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.
In a first, the James Webb Space Telescope (JWST) may have glimpsed a rare type of star that astronomers aren’t even sure exists. These “dark stars” might not have been fueled not by nuclear fusion but by the self-annihilation of dark matter.
Meteor-like fireballs in the atmosphere of the Sun rain down like showers of shooting stars during the phenomenon of coronal rain, scientists have found.
Using the Green Bank Telescope (GBT), US astronomers have detected a new binary millisecond pulsar. The newly found pulsar, designated PSR J0212+5321, belongs to the "redback" subclass and is located relatively nearby.
A group of Australian space scientists discovered a white dwarf star that appears to be in the beginning stages of crystallizing into a celestial diamond.
Astronomers studying black holes have serendipitously found another rarity: a dead star rocketing away from its birth supernova, leaving a comet-like trail of radio emission in its wake.
For the first time ever, we were able to identify the chemical traces of the explosions of the first stars in very distant gas clouds.
