A team using NASA’s James Webb Space Telescope has identified the new record-holder: a tiny, free-floating brown dwarf with only three to four times the mass of Jupiter.
It’s the first time such a disc, identical to those forming planets in our own Milky Way, has ever been found outside our galaxy.
A stunning river of stars has been spotted flowing through the intergalactic space in a cluster of galaxies about 300 million light years away.
The discovery of phosphorus in a molecular cloud at the edge of the Milky Way galaxy extends the presence of the element almost twice as far out as where it was known to exist.
Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
For the first time, artificial intelligence (AI) has searched for, detected, confirmed, classified, and announced a supernova discovery without any human intervention.
The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light.
After years of dedicated research and over 5 million supercomputer computing hours, a team has created the world's first high-resolution 3D radiation hydrodynamics simulations for exotic supernovae.
The James Webb Space Telescope has captured a new image of Supernova 1987A, one of the most famous exploding stars.
An international team of astronomers have identified a powerful magnetic field in the Wolf-Rayet star HD 45166, the exposed helium core of a star that has lost its outer layers of hydrogen.
NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang.
A record-breaking binary system has been found with a rotation so tight, both objects could comfortably fit inside the Sun.
A newly discovered star is so large, bright, and strange that its appearance could be pointing us towards a clump of dark matter in the sky.
A strange radio signal pulsing from a spot 15,000 light-years away could point to an unconfirmed type of star.
An unidentified source has been beaming out a pulse of radio waves every 22 minutes since 1988, astronomers say.
