The BOAT is the ruler of all gamma-ray bursts, releasing as much energy in seconds as the sun will in 10 billion years — and it could be revealing the secrets of these extreme cosmic blasts.

Using the James Webb Space Telescope, astronomers hunted supermassive black holes devouring stars in dusty galaxies — but laying in wait for their stellar victims.

It's 1961, and four intrepid cosmic explorers journey to space under the leadership of Reed Richards, where they encounter cosmic rays that change them forever. But what are cosmic rays?

A catalog of over 2,000 exploding white dwarf vampire stars, the largest ever gathered, has provided further evidence that dark energy is weakening.

Scientists have examined the interstellar invader 3I/ATLAS, finding evidence that it is packed with water that could be older than the solar system.

A death-defying star survived destruction by a ravenous supermassive black hole in a tidal disruption event, and came back to let the cosmic titan take another bite!

Astronomers have discovered a 200-light-year-wide Giant Molecular Cloud dubbed the Midpoint cloud that seems to be feeding star-building material to the heart of the Milky Way.

The long-serving space telescope saw the third interloper to enter the solar system from beyond its limits late on Monday morning (July 21).

The Orion Nebula, the Pleiades and the Hyades open clusters could represent the different phases of star clusters: baby, adolescent and elderly.

Astronomers have finally imaged the long theorized companion star of Betelgeuse, solving a mystery regarding its dimming that has persisted for millennia.

Astronomers have discovered a baby exoplanet "spiral architect" carving complex swirls into a disk of gas and dust around the young star HD 135344B.

Supernovas, kilonovas, gamma-ray bursts... oh my! The Nancy Grace Roman Space Telescope will uncover 100,000 of these explosions and many more powerful and violent cosmic events.

Astronomers have discovered an object at the edge of the solar system that is locked in a strange rhythmic dance with the ice giant Neptune.

Two teams of astronomers have simultaneously discovered a strange, spinning dead star that seems to defy our current understanding of both neutron stars and white dwarfs.

Astronomers have used the Chandra X-ray telescope to observe an exoplanet as it disintegrates because its parent star is bombarding it with radiation.

A massive doomed exoplanet on a death spiral toward its parent star has three possible catastrophic fates.

Up to 200 worlds investigated by NASA's exoplanet-hunting TESS satellite could be bigger than predicted, a finding that could impact our search for alien life.

Observations of a pulsar, consisting of a dead star spinning 600 times a second, and feasting on a stellar companion reveal the source powering its emissions.

Astronomers using the Subaru Telescope have discovered a strange new body in a weird orbit at the edge of the solar system, which could be bad news for Planet Nine theories.

Everything about the Infinity Galaxy, recently discovered by the JWST, is strange. One odd feature could be the 1st evidence of a "direct collapse" black hole.

Astronomers have witnessed the birth of an entirely new star system for the first time. The budding planets are forming around the infant star HOPS-315.

New research suggests that the Milky Way should be surrounded by as many as 100 undetected tiny and faint "orphan" galaxy companions.

New research indicates that cellular "pockets" that are the first step toward protocells, the precursors of life, could form in the methane seas of Saturn's moon Titan.

Astronomers have discovered that vampire white dwarfs that feast on victim companion stars have assistance in acquiring prey in the form of lurking third stars.
