Astronomer Caroline Herschel’s work discovering and cataloging astronomical objects in the 18th century is still used in the field today, but she didn’t always get her due credit.
Black holes are known for pulling in all kinds of stuff – including light. Here’s how that actually works.

Astronomers have detected the coldest star ever found to emit radio waves using the Australian SKA Pathfinder telescope.
An x-ray of the brightest ever gamma ray burst reflected off dust layers, creating extended ‘light echoes’ of the initial blast.
Radiation from the brightest cosmic explosion ever seen may have been mixing with gas and dust around its dying star – making the signal last longer.
New research shows that the destructive merging of a star and a planet expels huge amounts of gas, as shown in this artist’s impression.

Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.

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.

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.
