Astronomers have found evidence for a possible planet candidate in the M51 ("Whirlpool") galaxy, representing what could be the first planet detected outside of the Milky Way. Chandra detected the temporary dimming of X-rays from a system where a massive star is in orbit around a neutron star or black hole (shown in the artist's illustration). This dimming is interpreted as being a planet that passed in front of an X-ray source around the neutron star or black hole. A composite image of M51 with X-rays from Chandra (purple and blue) and optical light from NASA's Hubble Space Telescope (red, green, and blue) contains a box that marks the location of the possible planet candidate.
