JWST’s revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA’s Spitzer first, it wouldn’t have been possible.
The evolution of quantum technology is far from over.
Despite being the closest planet to the Sun, Mercury “only” reaches 800 °F at its hottest. Venus is always hotter, even at night.
Is there any good reason for assigning North and South the way we do, or could we have just as easily done the reverse?
Newborn stars are surrounded only by a featureless disk. Debris disks persist for hundreds of millions of years. So when do planets form?
Exoplanet LP 791-18d is likely to have an atmosphere and liquid water.
From life on Earth to the planet itself, there are four ways our planet will actually experience “the end,” no matter how we define it.
The answer to this question is key to understanding why anything exists.
Dinosaurs and other beasts were once thought to be the “undisputed masters” of Venus.
The new electrically conductive substrate could be the future of hydroponic farming.
Science and philosophy seem to be separate fields, but philosophical advancements have made the world more accepting of debate and unorthodox ideas.
Finland reveals that happiness is more about mindset than umbrella drinks and sun-warmed beaches.
The James Webb Space Telescope viewed Neptune, our Solar System’s final planet, for the first time. Here’s what we saw, and what it means.
In the early stages of the hot Big Bang, matter and antimatter were (almost) balanced. After a brief while, matter won out. Here’s how.
JWST just found its first transiting exoplanet, and it’s 99% the size of Earth. But with no atmosphere seen, perhaps air is truly rare.
Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.
Here on Earth, we commonly use terms like weight (in pounds) and mass (in kilograms) as though they’re interchangeable. They’re not.
We’ve only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
The Universe isn’t just expansion, but the expansion itself is accelerating. So why can’t we feel it in any measurable way?
Not every classic enjoyed rave reviews from the start.
In 1974, Hawking showed that black holes aren’t stable, but emit radiation and decay. Nearly 50 years later, it isn’t just for black holes.
Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here’s the greatest one ever witnessed.
The Universe certainly formed stars, at one point, for the very first time. But we haven’t found them yet. Here’s what everyone should know.
Valles Marineris is the Solar System’s grandest canyon, many times longer, wider, and deeper than the Grand Canyon. What scarred Mars so?
Our Sun will continue to grow, becoming a red giant and then a planetary nebula. Here’s how large it will get.

In the night sky for March of 2022, only stars and the Moon, not planets, will greet you. The real show, however, arrives just before dawn.
Epigenetic entropy shows that you can’t fully understand cancer without mathematics.
As early as we’ve been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here’s how they were made.
