X-ray data reveal 1st-ever planet orbiting stars in another galaxy

M51-ULS-1b is a Saturn-sized planet in the M51 galaxy. Amazing enough, but the system it’s in is even more amazing. The planet is in a binary star system, one star being a conventional massive star, the other being either a black hole or a neutron star. The small dark object is pulling the larger star apart, and as the gas spirals it friction heats it up enough that it emits X-rays… enough to be one of the brightest Xray sources in M-51. The planet then transits in front of the object now and then, blocking the Xrays and making it seem to shut off for a few hours.
