Empty, intergalactic space is just 2.725 K: not even three degrees above absolute zero. But the Boomerang Nebula is even colder.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
For linguists, the uniqueness of the Basque language represents an unsolved mystery. For its native speakers, long oppressed, it is a source of pride.
“A modern five-day forecast is as accurate as a one-day forecast in 1980.”
Wealth concentration among elites was common in ancient nations, but the scale on which it took place in Egypt’s 18th Dynasty was unprecedented.
Happiness is not a five-star holiday. It’s often the result of struggle — and asking for help, as author Stephanie Harrison recently told Big Think.
Science continues to amplify our view of reality.
National Geographic’s first James Webb Space Telescope book shows us the cosmos like never before.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.
We haven’t seen a partial eclipse lasting this long since 1440, and won’t again until 2669. North America is perfectly positioned for 2021’s.
Although many of Einstein’s papers revolutionized physics, there’s one Einsteinian advance, generally, that towers over all the rest.
The mass that gravitates and the mass that resists motion are, somehow, the same mass. But even Einstein didn’t know why this is so.
Particle physicists use gigantic accelerators to investigate the infinitesimal.
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
If something exists, it is by definition natural.
Einstein’s theory of general relativity introduced the concept of space having a shape. So, what is the shape of space?
All telescopes are fundamentally limited in what they can see. JWST reveals more distant galaxies than Hubble, but still can’t see them all.
A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.
Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.
Today, our observable Universe extends for 46 billion light-years in all directions. But early on in our history, things were much smaller.
Even if you or I will never actually visit these distant worlds, we now know they exist. They should fill us with wonder.
Every timekeeping device works via a version of a pendulum — even the atomic clocks that are accurate to nanoseconds.
If you had a clear western horizon, you had your shot at this view! On September 9, 2021, the Moon and Venus nearly overlapped. A simulated view of the post-sunset skies […]
Wind farms seem less productive when scientists incorporate more realistic atmospheric models into their output predictions.
We have long thought that Pluto was completely frozen solid, but the discovery of cryovolcanoes challenges that assumption.
Atomic nuclei form in minutes. Atoms form in hundreds of thousands of years. But the “dark ages” rule thereafter, until stars finally form.
There’s a whole lotta shakin’ goin’ on beneath the single plate of Mars.
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.
