Octopuses have three hearts: two just to pump blood through the gills and one more to circulate it to the organs. The circulating heart stops beating while an octopus swims, as swimming puts a lot of pressure on their bodies, making it harder for their hearts to pump blood. #science #sciencefacts #octopus #octopuses #heart #swimming #swimmingisexhausting

Before unleashing their infamous stink bomb, skunks stomp their feet, hiss, and sometimes even do a handstand to warn predators. So, if you see an acrobatic skunk - run. #science #sciencefacts #skunk #skunks

Despite their towering height and tree-like appearance, palm trees are actually more closely related to grasses, lilies, and bamboo than to traditional trees. They belong to the monocot group of plants, which means they have no rings, no true bark, and no real branches. Instead, their trunks are more like giant, reinforced stems.

Octopuses (and some other cephalopods) can rewrite their RNA on the fly to adapt to changes in their environment. This allows them to tweak how their neurons function, helping them survive in different temperatures or even enhance their intelligence. #science #sciencefacts #octopus #octopuses #geneediting #rna

Lake Vostok, a subglacial lake buried under 2.5 miles (4 km) of Antarctic ice, has been completely cut off from sunlight, the atmosphere, and the rest of Earth for millions of years - and is teeming with life. Scientists drilled down and found thousands of microscopic organisms, including bacteria, fungi, and even signs of complex life. #science #sciencefacts #lakevostok #subglaciallake #life #antarctica

WASP-76b, an ultra-hot Jupiter exoplanet about 640 light-years away. On the day side, temperatures soar past 2,400°C (4,350°F) - hot enough to vaporize iron into gas. WASP-76b is also tidally locked. The hot side vaporizes iron, and violent winds whip that iron vapor to the cooler night side, where it condenses into liquid metal droplets and falls as molten iron rain. #science #sciencefacts #exoplanet #hotjupiter #wasp76b #ironrain #metalrain

A massive cloud of gas located near the center of the Milky Way galaxy, which contains a significant amount of ethanol (ethyl alcohol), alongside other complex molecules, is essentially a giant cloud of "space alcohol." This cloud is often described as smelling like "raspberry rum" due to the presence of certain esters. #science #sciencefacts #gascloud #ethanol #ethylalcohol #spacealcohol #esters #raspberryrum #sagittariusB2

There’s a theoretical limit to how tall a tree can grow, and it’s about 426 feet (130 meters). Why? Because trees rely on capillary action and water tension to pull water up from their roots to their leaves. At a certain height, gravity overcomes the tree’s ability to transport water effectively, causing water columns to break and leading to air bubbles (embolism) in their vascular system. The tallest known tree, Hyperion, is a redwood in California, is 379.7 feet (115.9 meters). #science #sciencefacts #trees #limit #capillaryaction #watertension #hyperion

The One-Electron Universe Theory is an idea proposed by physicist John Archibald Wheeler in a phone call to Richard Feynman in 1940. It suggests that every electron in the universe is actually the same single electron, traveling back and forth through time. #science #sciencefacts #oneelectronuniverse #johnarchibaldwheeler #richardfeynman #electron

On September 3, 2002, astronomers discovered an asteroid with an unusual orbit around Earth. Further analysis of its trajectory and spectrographic evidence—specifically, the presence of titanium dioxide used in Apollo missions—revealed that it was actually the third stage of the Apollo 12 rocket, launched in 1969. #science #sciencefacts #asteroid #J002E3 #apollo12 #thirdstage #rocketstage

Surfing bathymetry refers to the underwater topography that shapes how waves break, including reefs, sandbars, and underwater canyons. The ideal bathymetry funnels wave energy toward shallow areas in a way that creates clean, rideable waves.

A humorous concept among the scientific community, often referred to as 'The Pizza Radius' or the 'Thermonuclear Culinary Zone,' suggests that for every nuclear explosion, there exists a precise mathematical distance where the heat flux would be just right to perfectly cook a frozen pizza. #science #sciencefacts #pizza #frozenpizza #nuclearexplosion #pizzaradius #thermonuclearculinaryzone

Spectralon is considered one of the whitest and most reflective materials known - reflecting over 99% of light. However, it’s not a pigment in the traditional sense - it's a highly diffuse reflective material made from polytetrafluoroethylene (PTFE, the same polymer as Teflon). #science #sciencefacts #spectralon #polytetrafluoroethylene #PTFE #reflectivematerial #whitestwhite

Galagos, also known as bush babies, have large, forward- -facing eyes that are fixed in their sockets, meaning they can't rotate their eyeballs. To compensate, they have extremely flexible necks that allow them to turn their heads almost 180 degrees. #science #sciencefacts #galago #galagos #bushbaby #eyeballs

Sperm whales have two nostrils, but unlike most animals, they are asymmetrically positioned. The left nostril is visible on the outside and forms the single blowhole used for breathing. The right nostril is hidden inside the whale’s massive head and is actually part of its complex echolocation system.

Michelangelo had an astonishing understanding of human anatomy, which was so advanced that some of his artwork reveals details that were unknown or poorly understood in his time. One particularly obscure example is the "Creation of Adam" on the Sistine Chapel ceiling. Researchers have noted that the depiction of God surrounded by angels resembles an anatomically accurate cross-section of the human brain. #science #sciencefacts #michaelangelo #creationofadam #sistinechapel #humanbrain #anatomy

90% of the atoms in our bodies were forged in stars - elements like carbon, oxygen, nitrogen, and iron. The remaining 10% comes from the Big Bang - the universe's first moments which created the lightest elements, hydrogen and helium.
