They discover two new rebellious planets in the Milky Way.

Scientists at the University of Warsaw, Poland, have discovered two new planets that do not travel in any particular trajectory through the phenomenon of gravitational microlenses that occur when a planet passes in front of distant background stars and the planet's gravity acts like a lens. did. It transforms and expands the star's light.

Not all planets are the same: solid, aquatic, gas, large and small. However, there is no planet orbiting any orbit. A new study published on the Arxiv premiere site called Rebellion Planet, Wanderer, Wanderer or Goa, has just found two of these interstellar planets.

As you can imagine, it is much more difficult to find a constellation if you do not drop the star while you are in front of the parent star. Therefore, in order to find such an orphan planet, the planet must pass by a distant background star and rely on the phenomenon of magnitational microlensing, in which the gravity of the planet acts like a lens to transform and expand the light of the planet. star

It is the method used by Przemek Mróz and his colleagues at the University of Warsaw, Poland, to discover these two new worlds (one of them is the smallest we have ever seen). The team used data from a gravity optical lens experiment, a sky study to find gravitational lens events.

The size is not yet defined.

Based on this very small number of ground mass worlds we have discovered, the team that studied how difficult it is to discover that the wandering planet is more common than the stars in the galaxy. Moment

One of the planets Mróz and his colleagues have witnessed is about two or twenty times the mass of Jupiter, depending on how much it is dust. The other is about 2.3 to 23 times the mass of the Earth, and it is one of the smallest wandering planets we have ever discovered.

The researchers can not be sure how big these planets are because they can not measure exactly how far away they are. The estimates are based on whether they are the main cause of the galaxy or farthest from the galaxy. The galaxy.

"It's like you're staring, someone has a lot of magnifying glasses, and sometimes you're moving in front of a star," he says. A new scientist David Bennett of NASA 's Goddard Space Flight Center. "If the magnifying glass is all the light of a star, how can you know how close the magnifying glass is?

The origin of this tremendous planet is still a mystery. One hypothesis implies that it can be an object ejected from the star system in which it was formed, while the other indicates that it can be a failed star. Only the Milky Way can have billions of planetary planets.

Now in our own neighbors there is a planet that we have yet to discover. It is almost certain that it exists: the mysterious planet 9.
