Most rocky exoplanets are exotic in composition and mineralogy, according to an analysis of the chemical composition of the so-called ‘polluted’ white...
The white dwarf observed by NASA’s Transiting Exoplanet Survey Satellite (TESS) is a member of the binary system TW Pictoris and is known to be accreting...
Using a technique called gravitational microlensing, which occurs when a star close to Earth momentarily aligns with a more distant star, astronomers have...
Using high-resolution observational of two very similar globular clusters, Messier 3 and Messier 13, astronomers have found an unexpected overabundance...
Using the NASA/ESA Hubble Space Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 8.9-hr variability in both...
HD 265435 is a binary system with an orbital period of around 100 min that consists of a white dwarf and a hot subdwarf star.

The newly-discovered white dwarf, designated ZTF J190132.9+145808.7 (ZTF J1901+1458), has a mass of 1.35 solar masses and a radius of 2,140 km (1,330 miles),...
Astronomers have detected lithium in the atmospheres of four cool and old white dwarfs, of which one also displayed atmospheric potassium. The relative...
Sagittarius A East (Sgr A East), a supernova remnant located strikingly close to the central supermassive black hole of our Milky Way Galaxy, resulted...
Astronomers using ESO’s Very Large Telescope (VLT) have captured a beautiful image of a planetary nebula called the Skull Nebula.
This image, taken by...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered a Jupiter-sized planet orbiting...
A series of ‘black dwarf’ supernovae will be the last astrophysical events to occur in our Universe prior to the so-called heat death, when the Universe...
Astronomers have for the first time used X-ray imaging to examine a calcium-rich supernova. Their findings, published in the Astrophysical Journal, show...
A white dwarf star called SDSS J124043.01+671034.68 (SDSS J1240+6710) is traveling at 900,000 km/h (559,234 mph) through our Milky Way Galaxy. It also...
Astronomers have analyzed a few carbon-oxygen white dwarfs in Milky Way’s old open clusters, and their findings help shed new light on the origin of...
A team of astrobiologists from the Carl Sagan Institute at Cornell University has developed a spectral field guide for Earth-like exoplanets transiting...
Professor Andrew King from the University of Leicester has shown that periodic X-ray eruptions from a galaxy called GSN 069 could result from the core...
A nova is a sudden, short-lived brightening of an otherwise inconspicuous star. It occurs when a stream of hydrogen from a companion star flows onto the...
