Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

The discovery of a monster-sized black hole in a pristine galaxy unspoiled by stellar death suggests growth via mergers between primordial black holes formed during the Big Bang.

The "Hubble tension," one of the most frustrating and lingering problems in science, could be solved if Earth and the Milky Way sit in a low-density void.

Radar signals from "leaky" civilian and military aviation systems could act as a beacon to alien life, revealing intelligent life on Earth while helping us pinpoint them.

Brown dwarfs, also known as "failed stars," could be corrupted by dark matter and transformed into "dark dwarfs" powered by the universe's strangest stuff.

As James Gunn's Superman (2025) races into cinemas faster than a speeding bullet, we look at the planet that could have hosted his home world and why he might be older than he looks.

Using the ALMA telescope, astronomers have revealed the internal structure of the first galaxies in the universe, hinting at how our cosmos took shape.

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.
