Astronomers have discovered in the planets of the Milky Way that they can become "orphans," that is, exist without a parent star.

It is worth noting that at the moment it is impossible to say with certainty whether these planets are "wandering". Researchers reported on their discovery on the arXiv website, reports "DS".

As scientists emphasize, planets traveling beyond stars do not emit light. However, they can be detected using the gravitational microlens method. With that, the researchers are trying to perceive the planets that fly freely against the backdrop of the stars. In this case, the planet plays the role of a lens, and the star increases its brightness for a while.

The scientists were able to detect two events that were given the names OGLE-2012-BLG-1323 and OGLE-2017-BLG-0560. The first of these could be caused by the passage of a planet the size of Earth or Neptune, and the second – the size of Jupiter or a brown dwarf. At the same time, researchers do not reject the possibility that both planets are associated with the parent star, but have very broad orbits.
