30 June 2015 — A NASA satellite controlled by Penn State University has detected a brief, super-bright, high-energy flare -- an X-ray nova -- erupting from a star system 8,000 light-years away from Earth named V404 Cygni. This system is in the constellation Cygnus and includes a black hole and a star just slightly smaller than the Sun. This black hole has been known to burp up an X-ray nova occasionally, but it had been slumbering since 1989 until the detection by NASA's Swift Gamma-ray Burst Explorer on June 15, just before 2:32 p.m. EDT. About 10 minutes after the detection by Swift, the Japanese " MAXI" experiment (Monitor of All-sky X-ray Image) on the International Space Station also picked up the flare.
