Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
The TOI-700 star system is home to four planets, including two in its habitable zone that could host liquid water.

With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.
All human development, from large cities to small towns, shines light into the night sky.
With the help of thousands of citizen scientists, a new study measured exactly how much brighter night skies are getting every year.
Astronomers have found that mysterious dark energy may originate in black holes.
There are many pieces of evidence to help explain why the Earth spins, and some major mysteries.

An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.
People travel hundreds or thousands of miles and spend a fortune to see the night sky in all its splendor. But we are literally blocking out the cosmic beauty above our homes.

Skies in the Northern Hemisphere have been graced by a rare, green comet. Now, it’s our turn to look for it in Australia – but the view will be dimming rapidly.
Discover how a picture of the sky can become a symphony.

Since ancient times, the stars have been set to music. Modern technology now enables scientists to convert images of space into real compositions.
The Carina star-forming region imaged by the JWST.
A year on since the historic launch of the most powerful infrared telescope in human history, we admire and explore some of the best images it delivered in 2022.
When two neutron stars merge and create a black hole, they produce a powerful blast of gamma rays.

Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
Your zodiac sign – like Sagittarius, the archer – might be in the stars, but your future isn’t.

Astrology and astronomy were once practiced side by side by scientists like Galileo and Kepler. And they’re more similar than you might think.
The James Webb Space Telescope is providing astronomers with images and data that reveal secrets from the earliest era of the universe.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
A new particle accelerator at Michigan State University is set to discover thousands of never-before-seen isotopes.
Facility for Rare Isotope Beams
A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
Astronomers think the most likely place to find life in the galaxy is on super-Earths, like Kepler-69c, seen in this artist’s rendering.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
There could be a planetary heist going on in the star-forming region NGC 3324 in the Carina Nebula.

We may have a stolen planet in our own Solar System.
Spiral galaxies like M100, pictured here, may hold answers about the nature of dark matter.

A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
VFTS 243 is a binary system of a large, hot blue star and a black hole orbiting each other, as seen in this animation.
Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
The unusual planetary system has a host star orbited by two giants. One has an incredible odd route around its star. And the other (unlike our own gas giants) is hellishly hot.
TRAPPIST-1e is a rocky exoplanet in the habitable zone of a star 40 light-years from Earth and may have water and clouds, as depicted in this artist’s impression.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
