Black holes have been a focal point for scientific exploration for many years, and while progress is being made in understanding them, researchers still have a long way to go.

NASA has released a new image of a black hole using its Chandra X-ray Observatory and Neil Gehrels’ Swift Observatory. NASA explains on its website that the image above shows rings around a black hole located in the binary system called V404 Cygni, which is about 7,800 light-years from Earth. So what makes these rings appear in the X-ray image?
The space agency explains that the rings are caused by the black hole blowing away material from a companion star located in its approximate vicinity. The star is estimated to be about half the size of the Sun, and the rings clearly seen in the image are not visible in visible light, but are clear as day through X-ray vision at as the material “glows”. Astronomers refer to systems like these as “X-ray binaries.” For more on this story, check out this link here.

Jak’s love for science, space and technology, and more specifically PC gaming, began at the age of 10. It was the day his father showed him how to play Age of Empires on an old Compaq computer. From that day, Jak fell in love with games and the progression of the technology industry in all its forms. Instead of the typical FPS, Jak has a very special place in his heart for RTS games.
