Observations carried out by NASA's Swift and Nuclear Spectroscopic Telescope Array (NuSTAR) space telescopes may have located the source of intense X-ray bursts emitted by supermassive black holes. According to NASA, the phenomenon can be attributed to a component of a black hole known as a corona.
An international team
of astronomers from Europe, Israel and the United States has
succeeded in shedding light on the origin of Type la supernovae –
powerful nuclear explosions in deep space that allow us to chart the
vast distances between galaxies. It is known that a white dwarf star
is responsible for creating the distinctive, intensely bright
explosion, but the cause of the supernovae are still a topic of hot
