The Oort cloud, a spherical shell of icy objects that surrounds the solar system, is home to 1 trillion comets.
Welcome! Here’s 5 Weird Things About Our Solar System
Picture this: you’re floating through space, high as a kite, surrounded by a trillion comets. That’s what it’s like in the Oort cloud, a spherical shell of icy objects that surrounds the solar system. It’s like being in a giant bong, but instead of a lot of weed smoke molecules, it’s a bunch of icy comets. Fun stuff to think about when you are stoned out of your mind. Not only is the Oort cloud home to 1 trillion comets, but it’s also home to some of the solar system’s most famous residents: Halley’s comet, Shoemaker-Levy 9, and Comet ISON. So if you’re ever feeling lonely, just remember that there’s a whole lot of cometary company out there in the Oort cloud.
Venus rotates backwards – it rotates from east to west.
If you were standing on Venus, the Sun would rise in the west and set in the east. That’s because Venus rotates backwards, compared to most other planets in the solar system. It rotates from east to west, instead of west to east. This is thought to be due to a giant impact early in Venus’s history. When a large object slammed into the planet, it caused the planet’s atmosphere and surface to spin in the opposite direction of its core. Over time, this process was further reinforced by the pull of gravity.
As a result, Venus rotates slowly and backwards, compared to most other planets. But that’s not all – Venus also has the longest day of any planet in the solar system! A day on Venus lasts for 243 Earth days. So if you’re planning a trip to Venus, be sure to pack your bong – you’re going to need it! But that’s not the only odd thing about Venus. The planet also has an incredibly thick atmosphere!
The atmospheric pressure on Venus is 90 times greater than the pressure on Earth, and the temperature is hot enough to melt lead. This used bong water-like atmosphere means that gravity has a very different effect on Venus.
Uranus has 27 moons, and 5 of them are larger than our moon.
Uranus is a gas giant, and it is the seventh planet from the Sun. It has 27 moons, and five of them are larger than our moon. Uranus’ atmosphere is composed of hydrogen, helium, and methane. Uranus’ core is thought to be made of water, ammonia, and methane. Uranus is about four times the size of Earth, and it has a diameter of about 51,000 kilometers.
Uranus was discovered in 1781 by William Herschel. Uranus is named after the Roman god of the sky. Uranus has a unique rotation; it rotates on its side. The length of one day on Uranus is about 17 Earth hours. Uranus’ orbit around the Sun takes 84 Earth years. Uranus is often referred to as an “ice giant” because it is thought to have a rocky core covered by a layer of ice.
Neptune’s moon Triton orbits in the opposite direction of everything else in the solar system.
Triton is a moon of the planet Neptune, and it has the distinction of orbiting in the opposite direction of everything else in the solar system. Triton is also the largest of Neptune’s moons, and it is thought to be a captured object from the Kuiper Belt.
Triton was named after the Greek god of the sea, and its surface is covered in ice. Triton’s orbit is unusually stable, and it is not expected to collide with Neptune any time soon. However, Triton’s orbit will eventually decay, and it will eventually be drawn into Neptune’s atmosphere and destroyed.
Pluto was downgraded from a planet to a “dwarf planet” in 2006 because it doesn’t meet all the requirements for being called a planet.
In 2006, marijuana smokers across the globe were dealt a blow when Pluto was downgraded from a planet to a “dwarf planet.” For many stoners, Pluto had always been their favorite planet, and they felt a sense of personal connection to it. After all, what could be more chill than a planet that’s so far away from the Sun that it’s almost always cold?
Not to mention the fact that its orbit is highly eccentric, meaning that it’s often closer to Neptune than it is to the Sun. In short, Pluto just seemed like the perfect planet for potheads. But alas, it was not meant to be. In 2006, astronomers decided that Pluto didn’t meet all the criteria for being called a planet, and so it was demoted to dwarf planet status.
This news was met with sadness and disbelief by many marijuana smokers, who felt that their beloved Pluto had been unfairly treated. However, despite its new status, Pluto still holds a special place in the hearts of stoners everywhere.
If you thought our solar system was strange before, just wait until you hear about some of the things that are going on beyond our orbit.
There’s a spherical shell of icy objects surrounding us called the Oort cloud, and it’s home to 1 trillion comets.
Venus rotates backwards – it rotates from east to west. Uranus has 27 moons, and 5 of them are larger than our moon.
Neptune’s moon Triton orbits in the opposite direction of everything else in the solar system. And Pluto was downgraded from a planet to a “dwarf planet” in 2006 because it doesn’t meet all the requirements for being called a planet.

Scented Secrets: 5 Terpenes You’ve Met Outside the Cannabis World!
Terpenes are the aromatic compounds responsible for the distinctive smells of cannabis strains. Over 200 different terpenes have been identified in the cannabis plant, each contributing to the wide spectrum of flavors, aromas, and effects. By understanding terpene profiles, consumers can select strains intentionally based on desired benefits. Beyond cannabis, these same terpenes that bring nuanced fragrance to bud also exist abundantly across the natural world. For example, the terpene limonene lends a zesty lemon scent when found in citrus fruits or cannabis. Myrcene produces an earthy, musky aroma reminiscent of cloves in both mango and some cannabis strains. Pinene conveys a pine forest scent whether in conifers or in a particular cannabis cultivar. Discovering terpenes both in and out of cannabis offers a deeper appreciation for these fragrant compounds.
Terpenes are aromatic compounds found abundantly in nature, especially in plants. These complex hydrocarbons are responsible for the distinctive smells we associate with plants – from the fresh lemon zing of citrus fruits to the soothing lavender fragrance of certain flowers.
In the cannabis plant, terpenes alongside cannabinoids like THC and CBD contribute to the wide spectrum of aromas, flavors, and effects found across different strains. Terpene profiles vary widely from strain to strain resulting in unique sensory experiences.
Understanding terpenes allows us to better appreciate the nuanced palate of cannabis. It also enables more targeted consumption by choosing strains with terpene profiles that align with desired effects and benefits.
Beyond the cannabis plant, terpenes play vital roles across the plant kingdom. They help attract pollinators and repel predators in nature. Their practical applications for humans span our food, medicines, cosmetics and more.
What Exactly Are Terpenes?
Terpenes are a large, diverse class of aromatic organic compounds produced in plants as well as some insects. The term “terpenes” refers to a broad category of hydrocarbons that contain hydrogen and carbon atoms.
They are synthesized in plant cells from precursor molecules such as pyrophosphates. Terpenes exist as oily liquids and evaporate easily at standard temperature and pressure. Most terpenes share a common molecular formula: C10H16
Terpenes alongside terpenoids (their oxygenated derivatives) comprise the largest group of phytochemicals, accounting for over 50,000 distinct compounds. They are the main constituents of plant essential oils and resins.
Chemically, terpenes consist of repeating isoprene units. The number of isoprene units determines terpene classification:
- Monoterpenes – 2 isoprene units (C10H16)
- Sesquiterpenes – 3 isoprene units (C15H24)
- Diterpenes – 4 isoprene units (C20H32)
- Triterpenes – 6 isoprene units (C30H48)
- Tetraterpenes – 8 isoprene units (C40H64)
The diverse molecular structures of terpenes are responsible for an equally wide spectrum of aromas, flavors, and effects. Subtle differences in their chemical structure can produce noticeably different smells.
For example, limonene and pinene both contain 10 carbon atoms but limonene has a lemon aroma while pinene smells resinous. These distinctive aromatic compounds interact with cell receptors in our nose impacting fragrance perception.
Terpenes in Cannabis: The Entourage Effect
Over 200 different terpenes have been identified in the cannabis plant. The mix of terpenes alongside cannabinoids like THC and CBD produce the Entourage Effect – a synergistic interaction that shapes the effects and aromas of different cannabis strains.
5 common terpenes found in and outside of the cannabis world:
This is the most predominant terpene in cannabis. Myrcene produces an earthy, musky aroma resembling cloves. It is commonly found in fruits like mango and herbs like hops. Myrcene induces relaxing, sedative effects. It also increases cell permeability allowing other terpenes and cannabinoids to better absorb.
As the name suggests, pinene produces a piney aroma much like a pine forest. It is found in conifers like pine trees and pine needles as well as herbs like rosemary and basil. Pinene acts as a bronchodilator potentially boosting airflow and alertness. It also enhances memory and concentration. Pinene also has various medicinal benefits.
This terpene has a strong citrusy smell evocative of lemon zest. It is naturally abundant in citrus fruits. Limonene quickens metabolism and raises serotonin levels for improved mood. It has anti-anxiety and stress-relieving properties. As a potent antibacterial and antifungal, limonene also promotes immunity.
This is the only terpene that directly interacts with the body’s endocannabinoid system. It has a spicy, peppery scent and taste. Caryophyllene is also found in spices like black pepper and cloves. It functions as a powerful anti-inflammatory and pain-reliever. It also reduces anxiety.
One of the most fragrant terpenes, linalool produces a floral lavender aroma. It is prevalent in lavender as well as mint. Linalool helps induce relaxation and sleep. It works as an anxiolytic agent that calms the nervous system bringing an overall sense of peace. It also boosts immunity.
The diverse terpene structures create an orchestra of flavors and effects in cannabis strains. Some strains will be more abundant in certain terpenes producing targeted benefits. For example, limonene-dominant strains can energize and thwart stress while linalool-rich strains can relax both body and mind.
Understanding terpene profiles allows consumers to identify strains better suited for desired needs whether that’s energy, focus, creativity, sleep or pain relief.
Terpenes in Everyday Life
Beyond the cannabis plant, terpenes play indispensable roles across the plant kingdom. Plants produce these aromatic compounds to attract pollinators like insects and repel predators like herbivores.
The fragrant terpene bouquets advertise nectar rewards to potential pollinators. These scented chemical cues also enable plant communication – signaling danger or summoning beneficial predators when pests are present.
For humans, terpenes have a diverse array of applications in our everyday lives. We may not know it, but terpenes impact much of what we eat, smell and use daily.
Here are some common uses of terpenes:
The perfume industry relies heavily on terpenes to craft distinctive scents and fragrances. Limonene lends a lemon verbena zing while more woodsy terpenes like pine and cedar provide an earthy base. Floral terpenes like linalool and geraniol are used for their rosy aromas.
Companies isolate or synthetize particular terpenes to produce unique proprietary perfumes and colognes. Terpene isolates are also used to create aromatic oils and candles.
Terpenes contribute to the sensorial experience of eating through taste and smell. Limonene brings a citrusy flavor, pinene an herbal quality, and menthol a minty cooling sensation.
The food industry maximizes terpenes to elevate flavors. For example, terpenes called R-carvones provide spearmint flavoring. Menthol cools sensation in gum and candy. Thyme and oregano owe their robustness to terpenes like thymol.
Terpenes are Generally Recognized as Safe (GRAS) additives by the FDA to enhance taste, aroma, and preservation. They Terpene isolates are also used to create aromatic oils and candles
Health and Medicine
Some terpenes exhibit therapeutic properties from anti-inflammatory to antimicrobial. The phytochemical potential of terpenes is now being researched for health applications.
For example, limonene has gastroprotective effects useful in managing acid reflux and heartburn. Pinene helps clear airways – it is even being investigated as a natural bronchodilator. Linalool and caryophyllene have anxiolytic properties that ease stress and anxiety.
Terpenes feature prominently in aromatherapy. Inhaling lavender oil high in linalool targets mood disorders. Terpenes like borneol are also used in traditional Chinese medicine. As more research emerges, terpene therapies may grow in popularity.
Cleaning and Cosmetics
Citrus-scented cleaners leverage limonene for its clean, freshening aroma and antimicrobial potency. Linalool and eucalyptol (minty terpene) are used in hygiene products for their pleasant scents and germ-fighting abilities.
Some terpenes even dissolve grease and oil. D-limonene (citrus peel extract) is often listed as an active ingredient in all-purpose cleaners and degreasers. It breaks up grime and grease naturally without synthetic chemicals.
Cosmetics also capitalize on terpenes. Linalool offers a delicate floral scent to lotions. Limonene and pinene infuse an uplifting aroma to products. Menthol provides cooling sensation. Cosmetics leverage the fragrance, flavor and bioactive properties of terpenes.
Given their natural bioactivity, terpenes have a long history of use as insecticides and pest repellents. Citronella oil high in citronellol wards off mosquitoes. Other terpenes work as natural solutions against fleas, moths, roaches and plant diseases.
With increased pest resistance to synthetic pesticides, terpene-based insecticides and repellents offer safer and eco-friendly alternatives. They biodegrade rapidly avoiding environmental accumulation.
Industrial Applications Some terpenes work as green solvents for their ability to dissolve substances. D-limonene safely dissolves oils, waxes, greases and resins. It replaces harsh solvents like toluene as an ecologically-friendly option.
The adhesive industry uses terpene derivatives in formulas for pressure-sensitive tapes, labels, laminates and more. Terpenes can also wet surfaces helping adhesive spread and penetrate better.
This is just a sampling of the many practical uses and applications of terpenes in our everyday lives. Their multi-sensory properties coupled with ecological advantages make terpenes highly versatile across many industries from food to medicine and beyond.
The Abundance of Terpenes in Nature
Terpenes represent the largest and most widespread class of phytochemicals in the plant kingdom. They are produced profusely as main constituents of essential oils and resins.
Beyond aroma and flavor, terpenes play vital ecological roles for plant survival. As potent biochemicals, terpenes help plants:
- Attract pollinators
- Deter herbivores
- Repel or kill pests/pathogens
- Mediate symbiotic relationships.
Plants utilize terpenes as chemical messengers in communication, defense and reproduction. Some terpenes are toxic to competing plants inhibiting growth (allelopathy). Others alter soil chemistry to gain a competitive edge.
Given their ecological importance, terpenes are ubiquitous across the plant kingdom. They are found in abundance in:
Fruits – Most fruits contain high concentrations of terpenes that give them distinct aromas, flavors and colors. Citrus fruits are abundant in limonene while muskmelon has characteristic muscone (musk terpene). Mangoes brim with myrcene conveying lush, fruity notes. Even the characteristic flavors of apples (pinene) and grapes (linalool) arise from terpenes.
Herbs and Spices – Pungent herbs and spices owe their fragrance and taste to terpenes. Black pepper teems with caryophyllene while eucalyptol brings the cool sensation of mint. Thyme and oregano get their robust herbal quality from thymol and carvacrol terpenes. Ginger gets its zing from shogaols and zingerone. The piquant aroma of cloves comes from eugenol.
Flowers and Plants – Flowers across various species produce terpenes to attract pollinators. Lavender contains bountiful linalool bringing its soothing floral aroma. Similarly, geraniol and nerol terpenes impart the sweet rose fragrance to roses. Conifers are loaded with pinene giving forests their pine scent. Even cannabis showcases over 140 different terpenes.
Insects and Animals – Terpenes are not exclusive to the plant kingdom. Insects like swallowtail butterflies biosynthesize terpenes for defense. Their caterpillars absorb terpenes from host plants making themselves toxic or distasteful to predators. Some terpenoids found in truffles and cannabis may originate from microbial production.
In short, terpenes are integral natural compounds found across the biological world. Their production spans the plant, insect and microbial domains. Next time you catch a whiff of pine, lavender or cloves, that’s the sensory power of terpenes!
The Entourage Effect: How Terpenes Interact with Other Compounds
In nature, terpenes rarely exist in isolation. More often, a mix of terpenes alongside other phytochemicals creates synergistic interactions that shape plant characteristics.
This biochemical “entourage effect” underlies the aroma, taste, color and medicinal benefits of plants.
Some key entourage effects of terpenes include:
Terpenes + Flavonoids
Flavonoids are color pigments in plants. Their interaction with terpenes influences flower color. Blue flowers owe their hue to anthocyanin flavonoids. Coexisting terpenes stabilize and modify the anthocyanin molecules producing variegated shades.
Terpenes + Cannabinoids
In cannabis, limonene amplifies absorption of THC and CBD through the blood-brain barrier. Myrcene also increases cell permeability allowing more cannabinoids to reach receptors. The terpene caryophyllene even binds to CB2 receptors directly making it psychoactive.
Terpenes + Curcuminoids
Curcumin, the main bioactive in turmeric, is fat soluble. Terpenes like d-limonene help curcumin dissolve and become more bioavailable to the body. This synergy enhances the anti-inflammatory benefits.
As these examples show, terpenes modulate bioactivity of other plant molecules from pigments to cannabinoids. The overall effect is amplified and balanced. Isolating single molecules misses these entourage benefits.
How Are Terpenes Created in Plants?
Terpenes are biosynthesized from basic molecular building blocks within plant cells. The primary precursor molecules for terpene synthesis include:
Acetyl Co-A – Derived from glycolysis, this coenzyme donates 2-carbon units
IPP (Isopentenyl pyrophosphate) – Formed from acetyl Co-A, IPP is a 5-carbon precursor
DMAPP (Dimethylallyl pyrophosphate) – Rearranged from IPP, DMAPP contains 5 carbons
IPP and DMAPP combine in a head-to-tail configuration to form monoterpenes, the C10 precursors to all terpenes.
This basic reaction is catalyzed by terpene synthase enzymes. Through alkylation, cyclization and oxidation steps, IPP and DMAPP are converted into the vast diversity of terpene structures.
For example, limonene synthase rearranges the geranyl pyrophosphate precursor into limonene. Further enzymatic steps add functional groups producing terpenoid derivatives.
The genes encoding these terpene synthesis enzymes have been widely studied and engineered in microbes for enhanced terpene production.
Certain growing conditions can also boost terpene content. Slow-dried cannabis often has higher terpene levels than rapidly dried cannabis. Stressors like high UV light and low nutrients may also stimulate terpene production.
Health Benefits of Key Terpenes
While research is still emerging, some terpenes appear to offer therapeutic properties and health benefits. Here are a few well-studied terpenes with promising bioactivity:
This abundant terpene has well-researched anticancer effects. It induces cancer cell death and restricts tumor growth. Limonene’s antioxidant action also promotes heart health. As a potent antibacterial and antifungal, limonene boosts immunity and battles pathogens. It relieves heartburn and gastroesophageal reflux when taken orally.
Used medicinally since ancient times, pinene exhibits potent antimicrobial effects against a broad range of bacteria, fungi and viruses. It acts as an expectorant to help clear airways. Pinene’s ability to cross the blood-brain barrier also makes it neuroprotective.
This is the only terpene known to directly activate endocannabinoid receptors. It selectively binds to CB2 receptors producing anti-inflammatory and analgesic effects similar to cannabinoids. Caryophyllene holds promise for pain relief and autoimmune conditions.
With its calming floral aroma, linalool is a proven anxiolytic that alleviates anxiety, stress and depression. It acts on GABA receptors and serotonin pathways bringing relaxation and improved mood. Linalool also completely inhibits growth of certain fungi and bacteria.
Clearly, terpenes are more than just aromatic compounds. From anxiety to pain, infection to inflammation, targeted terpenes may offer therapeutic benefits in the future. However, more rigorous research in humans is still needed.
Let’s Wrap it Up!
Terpenes constitute the largest class of phytochemicals performing vital roles across the plant kingdom. They contribute to plant communication, defense and reproduction. For humans, terpenes impart tantalizing aromas and flavors that make foods more palatable and even bioactive.
In cannabis, terpenes alongside cannabinoids create the Entourage Effect that shapes strain-specific characteristics. Analyzing terpene profiles enables more intentional consumption based on desired effects and benefits.
Beyond cannabis, terpenes have diverse applications across our everyday lives. They are ubiquitous in cleaning and cosmetic products, food and beverage, medicine and more. Nature’s biochemical factory has crafted over 50,000 terpene structures contributing sensory richness and ecological intimacy to the world.

Cosmic Revelations: A Journey into Space’s Mysteries
Space is silent. Wouldn’t you love a break from the constant buzz of everyday life? Space offers just that! The complete silence of space is an astounding concept, as it’s quite different from our noise-filled environment on Earth. This is primarily due to the absence of a medium, such as air, in the vacuum of space through which sound waves can travel.
Hello, all you stargazers and curious minds! Ready to take a deep-dive into the great unknown? Buckle up, as we’re about to embark on a cosmic journey exploring some astonishing facts about our universe. We guarantee this is an adventure that’s going to be truly out-of-this-world!
The Whispering Cosmos: Space’s Sound of Silence
Wouldn’t you love a break from the constant buzz of everyday life? Space offers just that!
Space is Silent:
The complete silence of space is an astounding concept, as it’s quite different from our noise-filled environment on Earth. This is primarily due to the absence of a medium, such as air, in the vacuum of space through which sound waves can travel. Sound, as we understand it, is created by the vibration of particles in a medium. In space, there are exceedingly few particles, and they are spread far apart, so sound waves cannot travel. Even in the event of a colossal cosmic explosion, there would be no sound to hear. The images we see from space telescopes are therefore silent, which is a thought-provoking contrast to the chaotic events we’re witnessing.
The Sun: Earth’s Mighty, Oversized Neighbor in Space
The Sun is over 300,000 times bigger than the Earth:
When we say the Sun is bigger than the Earth, we’re talking about its volume, which is a measure of how much space it occupies. The Sun is so large that you could fit over 1 million Earths inside it. That’s because its diameter is about 109 times that of Earth, and volume increases with the cube of the diameter. Furthermore, the Sun’s mass is about 300,000 times that of Earth, contributing significantly to its powerful gravitational force, which keeps the planets of our solar system, including Earth, in their respective orbits. The Sun’s immense size and mass enable it to hold a vast amount of fuel, allowing it to shine brilliantly and support life on Earth.
Halley’s Comet: The Celestial Nomad with a 75-Year Itinerary
Halley’s Comet, perhaps the most famous of all comets, is notable for its relatively short orbital period of around 75 to 76 years. This means that it returns to the inner parts of our solar system (where Earth is located) approximately every 75 years. Halley’s Comet has been documented for over 2000 years and its repeated returns have allowed scientists to study it in detail. Its last appearance was in 1986, and it’s expected to return in 2061. Every time Halley’s Comet swings by, it puts on a dazzling show, leaving a trail of debris that often results in meteor showers on Earth.
The Moon: The First Cosmic Pit-Stop for Humanity in Space
The Moon holds a significant place in human history as it was the first celestial body humans visited outside of Earth. This historic event took place on July 20, 1969, during the Apollo 11 mission by NASA. Astronauts Neil Armstrong and Buzz Aldrin made a safe landing on the Moon’s surface, marking a significant milestone in human exploration. Armstrong’s first step onto the lunar surface and his famous statement, “That’s one small step for man, one giant leap for mankind,” symbolized this incredible achievement. The moon landings represented the culmination of the space race and have fueled our interest in space exploration ever since.
Neutron Stars: The Galactic Whirling Dervishes
Neutron stars are remnants of massive stars that have undergone a supernova explosion. Once the outer layers of the star are blown away, the core collapses under gravity, resulting in a highly compact object primarily composed of neutrons. These neutron stars can spin incredibly rapidly due to the conservation of angular momentum. Before the explosion, the original star was spinning slowly, but as it shrinks in size during the supernova explosion, the rotation speed increases significantly, similar to a figure skater who spins faster when they pull in their arms. This can result in a neutron star spinning multiple times per second, becoming a pulsar if its magnetic poles emit beams of radiation that sweep past Earth.
Mercury and Venus: The ‘Moonless’ Duo of Our Solar System in Space
In the planetary lineup of our solar system, Mercury and Venus are the only ones without moons.
One leading hypothesis for this is their proximity to the Sun. The gravitational pull of the Sun could prevent these planets from acquiring and holding onto moons of their own. For a moon to orbit a planet, the planet’s gravity needs to be the dominant influence on the moon. But since Mercury and Venus are so close to the Sun, the Sun’s much stronger gravity would likely disrupt any moon’s potential orbit around these planets. In the case of Venus, another possibility is that it might have had a moon in its early history, which could have collided with another body or been destroyed by tidal forces. Despite extensive exploration of both planets, no evidence of current or past moons has been found to date.
Space- Endless Fascination:
So, there you have it! Our cosmic neighborhood is as captivating and diverse as it gets. Each silent corner, colossal star, punctual comet, human footprint, spinning neutron star, and moonless planet tell us a tale about the universe’s grandeur. As we marvel at the night sky, remember that we’re part of an ongoing cosmic saga, forever exploring, learning, and reaching for the stars. And remember, in this vast cosmic theatre, we’ve only seen the opening act! Join us again as we journey further into the mysteries of the cosmos.
