Astronomers have discovered an ultra-massive white dwarf with a unique carbon-hydrogen mixed atmosphere. Named WD J055134.612+413531.09 (WD J0551+4135...
According to new research by University of Warwick and University of Colorado, Boulder scientists, electromagnetic radiation from stars at the end of their...
There is growing evidence that evolution of red giant stars is often affected by an interplay with a nearby companion. Using the Atacama Large Millimeter/submillimeter...
Using the archival data from NASA’s Kepler Space Telescope, astronomers have identified a previously unknown dwarf nova that underwent a ‘supermaxima’...
SN 2006gy, a superluminous supernova discovered in 2006, gained its exceptional brightness when a normal Type Ia explosion smashed into a dense shell of...
A Neptune-like exoplanet orbits an Earth-sized white dwarf star called WD J091405.30+191412.25 (WD J0914 for short) once every 10 days, leaving a comet-like...
White dwarfs are dense, burned-out remnants of normal stars. Due to their strong gravitational pull, surface atmospheres of these ancient objects should...
Astronomers using NSF’s Green Bank Telescope have identified a record breaking neutron star with the highest mass yet known. The object, called MSP J0740+6620,...
Astronomers using the KPED (Kitt Peak Electron Multiplying CCD demonstrator) instrument at NSF’s Kitt Peak National Observatory have discovered ZTF J153932.16+502738.8,...
Astronomers have used NASA’s Transiting Exoplanet Survey Satellite (TESS) to see what was happening around the supernova ASASSN-18tb in the first moments...
In celebration of the 29th anniversary of the launch of the NASA/ESA Hubble Space Telescope, astronomers captured this colorful look at the hourglass-shaped...
Astronomers using the Gran Telescopio Canarias have spotted a low-mass planet-like object in a disk of gas and debris around SDSS J122859.93+104032.9,...
Professional astronomers and volunteers working with the Backyard Worlds: Planet 9 citizen science project have spotted the oldest and coldest known white...
Astronomers using ESA’s galaxy-mapping spacecraft Gaia have discovered the first direct evidence that white dwarfs form crystal cores of metallic oxygen...
Plasmas are naturally formed at high temperatures, such as those reached in the interiors of stars. Neutral plasmas consist of equal numbers of positive...
Astronomers using the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument on ESO’s Very Large Telescope have captured dramatic...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers found evidence that a white dwarf and a brown dwarf collided in a ‘blaze of...
