Read the latest news about NASA's James Webb Space Telescope.

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this transformation, they may vomit out more stellar material than we knew.

With the aid of citizen scientists, astronomers have discovered an erupting cataclysmic variable star in a rarely seen evolutionary stage.

Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own parent stars by being too clingy.

Astronomers have discovered the first evidence of a white dwarf wiped out by a double-detonation supernova, also providing space-lovers with stunning eye-candy.

Cosmic archeologists have used the James Webb Space Telescope to excavate ancient disk galaxies that tell the story of how the Milky Way and other modern galaxies evolved.

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black holes or a cosmic particle accelerator.

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.

With the aid of NASA's exoplanet-hunter TESS, citizen scientists have discovered a new gas giant that is cool, literally and figuratively.

Andromeda never looked as good as it does in a new image from the Chandra X-ray observatory and a range of powerful telescopes. A fitting tribute to dark matter pioneer Vera Rubin.

Astronomers have discovered the first step in planet birth, finding hitherto unseen structures in 78 planetary disks in the star-forming region of Ophiuchus.

A walk in the desert and a curious discovery could have revealed that the secrets of alien life grow in the harshest conditions on Earth in the form of lichen.

With exactly a month to go until the release of Fantastic Four: First Steps, the final trailer reveals more Galactus, more Franklin, but no Clobberin' Time... yet.

The James Webb Space Telescope has discovered its first exoplanet, TWA 7b which is also the lightest exoplanet ever to be directly imaged.

A mysterious and powerful blast of radio waves detected last year, suspected to originate far beyond the Milky Way came from a long-dead NASA spacecraft in Earth's orbit.

Astronomers have discovered the strange dance that leads to the creation of rare "double hot Jupiters" in binary star systems that are "just right."

A radio signal from the dawn of time could help scientists weigh the first stars and reveal how they lifted the cosmic darkness.

The Vera C. Rubin Observatory has released its first images, providing a staggering glimpse at the observing power it will unleash when it begins its decade-long survey.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our place within the multiverse.

Astronomers have taken an unprecedentedly detailed look at the tendrils and filaments that wrap around supermassive black hole-dominated galaxies of Abell 2255.

The Rubin Observatory will reveal its first images on Monday. Space.com spoke to scientists who explained why this will be a monumental event for astronomy.

The monsterous 85-mile-wide comet C/2014 UN271 isn't just the largest icy rock in the Oort Cloud, it's the second most distant that is chemically active.

Using the XMM-Newton telescope, astronomers have discovered a vast 23 million light-year-wide tendril connecting galactic clusters and containing much of the universe's missing matter.
