Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.

Astronomers using the James Webb Space Telescope have detected phosphine gas in the ancient brown dwarf Wolf 1130C, a discovery that contradicts years of predictions about how phosphorus behaves in ...

Astronomers using the Hubble Space Telescope have discovered a "ultra-massive white dwarf that formed when a white dwarf merged with another star," according to the Goddard Space Flight Center. Credit ...

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in ...

For decades, astronomers have detected an unusual mix of ionised gas in the local clouds. Roughly 20% of hydrogen and 40% of ...
