Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White DwarfA supermassive black hole in a distant galaxy is once again surprising scientists. In 2018, a black hole called 1ES 1927+654, ...
Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations ...
It's the definition of "no pain, no gain." The rapid spin of this white dwarf, that is vampirically taking stellar matter away from a companion star, could be explained by its shrinking radius.
In this artist’s concept, matter is stripped from a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. Astronomers ...
