NASA’s Transiting Exoplanet Survey Satellite (TESS) has unveiled TOI-4616 b, an Earth-sized planet orbiting a nearby M-dwarf star. Published in a March study on the preprint server arXiv, the findings ...

Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...

A naked-eye star’s 50-year mystery is solved—its bizarre X-rays come from a hidden, feeding white dwarf.

The six known DAQ type white dwarfs exhibit log (C/H) > –0.5 and appear in optical spectra. WD 0525+526 shows how many merger remnants may hide beneath pure hydrogen layers, detectable only in ...

For all the talk about life across the cosmos, Earth remains the only confirmed example. That single data point makes your place in the universe feel both ordinary and strange. Two facts sharpen the ...
