Astronomers used the sharp vision of NASA's Hubble Space Telescope to measure the mass of a dead star known as "white dwarfs".
A team of scientists at the W. M. Keck Observatory in Hawaii have discovered what seems to be a remnant of a massive object that was torn apart by a white dwarf star some 170 light-years from Earth.
An international team of scientists is trying to take a peak on what will happen to Earth five billion years from now by looking at a 10-billion-year old star with the help of one of the most powerful radio telescopes in the world.
It pays to clean one's basement once in a while. A 1917 astronomical glass plate was unearthed from the collections of Carnegie Observatories in Pasadena, California revealed the first-ever evidence of exoplanetary system.
Type Ia supernovae are some of the most rare and dazzling phenomena in the Universe, and yet astronomers were recently lucky enough to catch a glimpse of one in action. And now, their discovery is shedding light on the mysterious origins of such spectacles, according to a new study.
A pair of white dwarf stars located deep inside the planetary nebula Henize 2-428 are slowly moving closer and closer towards each other, destined to collide in a catastrophic supernova explosion.
In the case of supernovae, it was long thought that dying white dwarf stars were left out of the equation, simply too small to spark the awe-inspiring explosion. Now researchers believe they figured out how some stars managed to still pull off the self-destructive stunt - re-igniting with the help of a nearby buddy.
A team of astronomers and astrophysicists has found that some of the Universe's loneliest supernovae are likely created from collisions between white dwarf and neutron stars, according to a recent study.
Astrophysicists have recently identified a new source of high-energy gamma ray emissions using NASA's Fermi Gamma-ray Space Telescope. Stellar explosions, called novae, have been found to release a surprising amount of gamma radiation, showing just how little we know about these rays.
A team of astronomers has identified an Earth-sized "diamond" in space, or possibly the coldest, faintest white dwarf star ever detected.
