    NASA detects odd X-ray signal 240 million light years away


    There's never a dull moment — er, light year — in outer space.

    NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton spotted an unusual X-ray signal in the data received from the Perseus galaxy cluster some 240 million light years away.

    The signal appeared as an intensity spike at an X-ray wavelength where none had been seen before.
