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).

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 perfectly cook a frozen pizza.

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. Thanks for sharing, Olivia S.! #surf

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 the 3rd stage of Apollo 12.

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 #sciencefact

The stay apparatus is a system of muscles, ligaments, and tendons in horses that allows them to stand on three legs while resting the fourth. This unique adaptation helps horses sleep while standing up and reduces wear and tear on their legs. #science #sciencefacts #horse

There’s a theoretical limit to how tall a tree can grow, and it’s about 426 feet (130 meters). #science #sciencefacts #trees #limit #capillaryaction #watertension #hyperion

Deep beneath Earth's surface, there’s an enormous amount of water trapped inside a special blue mineral called ringwoodite in the mantle. #science #sciencefactds #water #earth #mantle #ringwoodite

Surrounding a quasar called APM 08279+5255, about 12 billion light-years away, is a water vapor cloud containing 140 trillion times the water of Earth’s oceans. #science #sciencefacts #quasar #apm08279 #water #watervapor

PSR J1748-2446ad is the fastest known spinning pulsar. At about 20 kilometers (12 miles) across, it spins over 700 times a second - at the equator that’s 24% the speed of light. #science #sciencefacts #pulsar #fastest #psrj17482446ad

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."

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 into rain.

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. #science #sciencefacts #lakevostok #subglaciallake #life #antarctica

Scientists have found that being in love activates the brain’s reward system in a way that can actually reduce physical pain. #science #sciencefacts #love #pain #feelnopain #happyvalentinesday

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. #sciencefacts #octopus

Despite their towering height and tree-like appearance, palm trees are actually more closely related to grasses, lilies, and bamboo than to traditional trees. #science #sciencefacts #palmtrees #grass #monocot

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

Jonathan, a Seychelles giant tortoise, is the world's oldest known living land animal. As of 2025, he is estimated to be around 192 years old. #science #sciencefacts #jonathanthetortoise #tortoise #gianttortoise #seychellesgianttortoise

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. #science #sciencefacts #octopus #octopuses #heart #swimming #swimmingisexhausting
