Scientists witness a white dwarf’s massive X-ray explosion for the 1st time ever

Blink and you’ll miss it — a searing explosion of X-rays 60 times hotter than the surface of the sun. 

That’s what astronomers have observed on a distant white dwarf star for the first time ever. In July 2020, a group of scientists from European universities were scanning the skies with the German eROSITA X-ray telescope, an instrument that specializes in soft X-rays and orbits a gravitationally stable point in space about 930,000 miles (1.5 million kilometers) from Earth. The researchers happened to catch an extraordinarily bright explosion, which they have identified as a white dwarf explosion called a nova.
