The European Southern Observatory announced that at least 70 planets have been discovered that do not orbit the Milky Way.
The research on the so-called “passing” planets has been published in the journal Nature Astronomy.

European Southern Observatory telescopes recorded tens of thousands of images.
Also, 170 potential planets have been identified in the Milky Way, and at least 70 images have been determined to have been “passing planets”, meaning planets without a defined orbit.
Astronomers can often observe another planet passing in front of a star.
The planet that enters between the Earth and the star creates darkness by blocking the light emitted by the star in question, and the dimming also shows that there is a planet in that region.
It is difficult to observe the passing planets because they do not revolve around a star, and this research also focused on the faint effects of radiation emitted by the planets since their formation.

The tiny motions, colors, and luminosity of millions of sources were measured over a wide area of the sky.
These measurements also made it possible to identify the weakest objects in the region, the “passing” planets.
