An international group of astronomers has discovered what may be the first visible exoplanet outside our galaxy, he says Salvador Nogueira of Folha de S. Paulo.

A planet beyond the Milky Way?
The star found will be about the same size as the planet Saturn, and will be in the galaxy M51, located 23 million light years from here, near the sky of the northern constellation Ursa Major. And until then, let’s agree, nothing out of the ordinary. The strange thing is that the planet is spinning. We are talking about binary X-rays.
This is a double star, one of which has exploded and become one of two possible stellar bodies: a black hole or a neutron star.
By gravity, this dead star engulfs matter from its living neighbors and, in the process, produces a disk of gas and dust around it. By rotating toward a compressed object, this material becomes a powerful X-ray emitter.
Researchers led by Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics think it’s highly probable that planets exist around these stars, because planets have been discovered around neutron stars in our Milky Way. (By the way, the first exoplanet discovered in the history of astronomy, in 1992, orbited one of these stellar bodies, and not a star in its active phase, like the Sun).
After their reasoning, they hypothesized that some of these systems would align so that the planet would pass in front of the compressed X-ray emitting star, temporarily blocking the flow.
Such transits can be detected as “flashes” in X-rays, even at great distances, such as those separating other galaxies.
