An international team of astronomers have finally caught a glimpse of an expanding thermonuclear fireball from an exploding white dwarf. It's the first time this kind of data has ever been captured, allowing the researchers to study how the fireball evolves and rapidly expands into space.
Astronomers have detected an ancient stellar remnant that's 10 times fainter than the dimmest white dwarf ever discovered. Fortuitously orbited by a pulsar, this cold and collapsed star consists of crystallized carbon — essentially making it an Earth-sized diamond in space.
Typically, astronomers observe the dimming of a star whenever an exoplanet passes in front of it. But what could possibly cause a star to periodically increase its illumination when an object passes in front? The answer, say scientists, is a newly confirmed phenomenon known as "self-lensing."
Everyone, say hello to Type Iax, a new classification of supernova that astronomers are calling “the runt of the supernova litter.” But these celestial blasts are hardly subtle; they're a newly documented and surprisingly frequent subcategory of supernova in which helium-sucking white dwarfs survive the ensuing…
Scientists at the University of Oslo have discovered a completely new way for atoms to bond together — but these researchers won't be replicating the effect in the lab any time soon. The previously unknown bonding mechanism can only happen in the vicinity of white dwarfs where their intense density and spin creates…
Two newly-discovered white dwarf stars exhibit extremely odd properties, almost resembling planets. Their dense cores are exposed, shrouded in a layer of oxygen. Are these dying stars potentially habitable?
