Physicists have increasingly begun to view life as information-processing “states of matter” that require special consideration.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it most likely caused the impact itself.
Grab a sword, a small plate, and a young child. We’ve got a demon to summon.
The number of planets that could support life may be far greater than previously thought, a recent discovery suggests.
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
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.
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.
Newborn stars are surrounded only by a featureless disk. Debris disks persist for hundreds of millions of years. So when do planets form?
The Vera C. Rubin Observatory in Chile will image the southern sky using the largest digital camera ever built.
Back in 1990, we hadn’t discovered a single planet outside of our Solar System. Here are 10 facts that would’ve surprised every astronomer.
The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it’s plausible.
In our Solar System, even the two brightest planets frequently align in our skies. But only rarely is it spectacularly visible from Earth.
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use “years” to measure time. Can we do better?
As Uranus approaches its solstice, its polar caps, rings, and moons come into their best focus ever under JWST’s watchful eye. See it now!
Some microbes can withstand Earth’s most inhospitable corners, hinting that life may be able to survive similarly extreme conditions on other worlds.
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 space telescope’s findings challenge the notion of a galaxy brimming with life.
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.
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.
In a distant galaxy, a cosmic dance between two supermassive black holes emits periodic flashes of light.
Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It’s not; it’s hard to mess with success.
All across the Universe, planets come in a wide variety of sizes, masses, compositions, and temperatures. And most have rain and snow.
Following the advent of human space flight, NASA began naming missions after children of Zeus.
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Comet A3, also known as Comet Tsuchinshan-ATLAS, has sprung to life since 2024’s last equinox. Here’s how to catch the show for yourself.
Long before the search for biosignatures, scientists imagined a cosmos teeming with intelligent life.
If the past is any guide, things are going to take off quickly.
