Calculating the way three things orbit each other is notoriously tricky — but a new study may reveal 12,000 new ways to make it work.
We currently know of 5,502 planets beyond the solar system, but we've only found the tiniest fraction of the planets astronomers think lie elsewhere in the universe.
Almost every galaxy in the universe has a supermassive black hole at its center. So why is it so hard to find young black holes actively feeding?
Astronomers studied the remains of a massive star ripped apart by a black hole in an epic astro-forensic murder investigation.
An infant star system contains the basic building block for organic chemistry, new James Webb Space Telescope images reveal.
SN 2023ixf is the closest supernova to Earth in more than a decade — and the perfect excuse for intelligent aliens to get our attention, new SETI research suggests.
Astronomers have confirmed the presence of phosphates — a crucial ingredient for life — in a plume of icy water gushing out of Saturn's moon Enceladus.
New simulations show that dying stars release enormous "cocoons" of gas that may rattle with space-time ripples called gravitational waves.
A new analysis of Kepler data shows that one-third of small stars called M dwarfs may have the potential to host life.
Light is faster than anything else in the known universe, though its speed can change depending on what it's passing through.
The James Webb Space Telescope took its first close look at a "mini-Neptune" — the most common type of planet beyond our solar system — and found signs of water.
Astronomers comparing maps of the universe uncovered the nearest example of a black hole devouring a star ever detected.
A satellite from the United Arab Emirates revealed that Mars' moon Deimos is made of the same material as the Red Planet itself, hinting at an ancient collision.
The European Space Agency is sending a probe called JUICE to Jupiter's moons — and we've got all the info you need to watch the launch.
A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds.
Astronomers using the James Webb Space Telescope have detected the four oldest galaxies in the known universe, which are forming stars much faster than thought possible.
Earth's magnetic field protects life on our blue planet — and astronomers just found evidence of a magnetic field on a rocky exoplanet 12 light-years away.
NASA's James Webb Space Telescope measured the temperature of the Earth-like planet TRAPPIST-1b and found that it is too hot for humans and likely has no atmosphere.
An object once thought to be a radio galaxy is actually an active black hole that changed angles to point directly at Earth, new research suggests.
Alien life could thrive in terminator zones, the edges between the light and dark sides of planets that are tidally locked with their host stars.
Simulations show that collisions between moons and planets may be a regular danger for possible extraterrestrial life.
NASA astronomers used the Hubble Space Telescope to measure the mass of a white dwarf, an important step for understanding how stars die.
Mysterious fast radio bursts (FRBs) helped astronomers weigh our galaxy, and reveal that some matter is missing.
