Buried inside data Voyager 2 gathered at Uranus more than 30 years ago is the signature of a massive bubble that may have stolen a blob of the planet's gassy atmosphere.
The winds and radiation blowing out of quasars — the most energetic objects in the universe — can kill star formation galaxy-wide, new research shows.
The bubble concept could explain one of the strangest mysteries plaguing astrophysics: Why can't we tell how fast the universe is expanding?
A large and "potentially hazardous" asteroid is poised to fly by Earth next month, but don't worry — it poses no threat to Earth.
In this episode of Life's Little Mysteries, we'll take a closer look at a mysterious object in space that's our closest cosmic neighbor: the moon.
As satellites orbiting Earth have observed, as coronavirus has progressed, there has been less air pollution over Italy and lowered nitrogen-dioxide emissions over China.
For years, amateur astronomers have been waiting for a bright, naked-eye comet to pass by Earth — and finally, such an object may have arrived.
Could Mercury's close orbit to the sun help the planet generate ice? This sounds like a paradox, but a new study shows how it could happen.
Freeman Dyson may be gone, but his famous alien-hunting idea will likely persist far into the future.
The red supergiant star Betelgeuse is nearing the end of its life, and researchers are preparing for what it will look like when the star dies in a fiery explosion called a supernova.
We all know that iconic scene: Luke Skywalker staring forlornly — and perhaps wistfully — at the double sunset of his home planet, Tatooine.
As the world scrambles to confront the disease caused by a novel coronavirus, Italy has been forced to take such dramatic measures that the country's emissions have changed, as seen from space.
As the universe cooled in the era after the Big Bang, a supermassive black hole had already formed in the center of a galaxy, forming a giant engine of energy we can still see today.
