A group of astronomers believe that a celestial body created by the collision of two white dwarfs could be a new source of X-rays.
According to News i, The XMM-Newton X-ray Telescope is a space observatory launched by the European Space Agency (ESA) in December 1999. The telescope captured an image of a new type of star that had never been seen before on X-rays. This strange star was formed after the collision and merging of two “white dwarfs” (White Dwarf). Instead of harming each other, white dwarfs form a new mass that glows with X-rays after colliding.
A team of astronomers used the XMM-Newton X-ray telescope to study the object, which was first discovered in 2019. Astronomers at the time reported that the star was too bright and too large to be an ordinary white dwarf. In their view, the object is a new type of star that has survived the merger of two white dwarfs.
Based on new information, the team now believes that what we see in the picture is a new type of X-ray source powered by the fusion of two white dwarfs.
