Although ESA's GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to o...

In a surprising find, astronomers discovered a faraway galaxy that doubles as a cosmic "magnifying glass." At 9.6 billion light-years away, it could be the most distant such object known to science, NASA announced.

In a classical nova, a white dwarf siphons material off a companion star, building up a layer on its surface until the temperature and pressure are so high (a process which can take tens of thousands of years) that its h...
