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.
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that can affect the surroundings of black holes.
Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
New findings suggest the water originates from the space between solar systems, billions of years before the birth of our sun.
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.
The aftermath of an epic collision involving at least one neutron star has been captured for the first time in the millimeter range of radio frequency wavelengths.
Far out in the Milky Way, roughly 22,000 light years from Earth, a star unlike any other roars with a magnetic force that beats anything physicists have ever seen.
The discovery of a neutron star emitting unusual radio signals is rewriting our understanding of these unique star systems.
The eROSITA telescope aboard the Spektr-RG space observatory at the L2 Lagrange point captured the first time in what is known as the ‘fireball’ phase of a classical nova.
ESA's XMM-Newton has found a pulsar - the spinning remains of a once-massive star - that is a thousand times brighter than previously thought possible.
Neutron stars are one possible suspect responsible for an abundance of positrons in the Milky Way. Now astronomers have caught one red handed.
Just 4,000 light-years from Earth is a strange, star-sized object. It’s been observed by radio telescopes, but astronomers aren’t sure what it is. They call it a long period transient.
By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind fast radio bursts after all. The bursts may come from a highly magnetized, isolated neutron star - magnetar.
