Octopuses have three hearts, blue blood, and nine brains — and the central brain has so little control over the arms that each one essentially decides what to do on its own
Psychology
NASA's playbook for staying intact through long isolation
Constellations
There is no sound in space, but NASA records the electromagnetic vibrations of planets and converts them to audio, and Saturn sounds genuinely haunting

The light hitting your eyes from the sun right now left its surface 8 minutes ago — but the energy behind it may have spent roughly 100,000 years fighting its way out from the core
Earth Observation
There are roughly 170 trillion pieces of plastic floating in the world's oceans, and the satellite work mapping where it concentrates wasn't designed to look for plastic at all
Space Industry
Buzz Aldrin took communion on the surface of the moon before he took his first step on it, and NASA asked him not to mention it on the live broadcast
Climate Science
The Parker Solar Probe is now moving at 430,000 miles per hour, fast enough to cross the continental United States in 20 seconds, and it survives skimming the Sun's corona because a four-and-a-half-inch slab of carbon foam stays at room temperature on the side facing 2,500-degree plasma.

The Hubble Space Telescope was nearly blind for its first three years because its primary mirror was ground too flat by 2.2 micrometers, and NASA's reputation depended on a 1993 repair mission built around corrective optics the size of a refrigerator
Aerospace
NASA's Perseverance rover is about to finish its first marathon on Mars, and it's taken the six-wheeled robot more than five years to do it

The James Webb Space Telescope is currently observing galaxies that formed 13 billion years ago, and several of them shouldn't exist according to the model cosmologists were using when Webb launched

A hidden layer of microbial life has been found beneath the Atacama Desert, and it may be the closest Earth can get to rehearsing the search for life on Mars

The warmth of the sun on your skin began its journey up to 100,000 years ago — bouncing through the solar interior for almost all of that time before the final 8-minute sprint to Earth, meaning the energy reaching you now started moving when humans were still living in caves.

The International Space Station is travelling at 17,500 mph as you read this, and the astronauts inside it are aging measurably slower than you are
Science
The cells in your eyes that detect light are technically part of your brain, pushed outward during embryonic development, which means when you look at the night sky your brain is physically touching the photons that left distant stars thousands of years ago.
