Eruptions of plasma piling atop one another, solar wind streaming out in exquisite detail -- the closest-ever images of our ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

Auroras (also called the northern and southern lights) are visible from the ground after powerful solar storms, but these ...

Researchers stitched together hundreds of images from the Very Large Telescope to form a breathtaking photo of a nearby ...

Hubble’s crystal-clear look at NGC 1786—an ancient globular cluster tucked inside the Large Magellanic Cloud—pulls us 160,000 ...

NGC 1786’s mixed-age stars suggest globular clusters aren’t one-generation wonders, offering fresh clues to galaxy formation far beyond the Milky Way.

How does a star form from the cold, turbulent gloom of a molecular cloud? Three years have already passed since the James Webb Space Telescope has been revealing how, most recently by removing the ...

What lies within a toe bean? According to NASA’s James Webb Space Telescope, mini toe beans composed of gas, dust, and stars. Since kicking off full science operations in July 2022, the James Webb Spa ...

NASA confirms the existence of TOI‑1846 b, a nearby hot super-Earth that could contain water, initially observed by NASA's ...

Deep within the Milky Way’s core, researchers have uncovered cold gas clouds racing through a superheated galactic wind.

Cosmic dust does far more than float through space. It's the raw material from which stars, planets and possibly even life ...

A quiet, glowing gas cloud has been hiding in plain sight not far from Earth. For decades, astronomers have predicted that some of the galaxy’s molecular gas — the fuel for star birth — might be ...
