For the first time in history, people found this in the universe

A landmark discovery of science and technology, marking the era of human influence far beyond our Milky Way framework.

The previously identified human planets - including candidates thousands of light years away - have a common trait. That's all in the scale of the Milky Way.

But you probably already know, the universe has a multitude of different galaxies, the Milky Way is just a part of it. However, the planets of other galaxies are not capable of being observed by humans.

For the first time scientists found planets belonging to another galaxy.

However, everything has changed. Recently, for the first time in history, astronomers have published a list of our outer galaxies . The great public belongs to data from NASA's Chandra X-ray Observatory .

As noted, the new planets are quite diverse in size, ranging from just the Moon, to the size of Jupiter. And their galaxy is located 3.8 billion light-years away.

"We are excited about this discovery. This is the first time our outer galaxies have been found," said Xinyu Dai, an astrophysicist from Oklahoma University.

More specifically, experts analyzed an astronomical phenomenon called "microlensing" . This is the phenomenon that light emitted from stars or very far away is bent by gravity from another celestial body. It could be another star, or cosmic black hole.

If the light source is blocked, the obstacle will look like a lens, creating a spectral disc. The brightness of the spectral range is affected if there is another planet present. And analyzing those spectra is also the only way at the present time that allows us to identify planets far away.

This effect was predicted by Einstein in the theory of relativity, so "that spectral disk" is also called "Einstein disk."

The new planets are quite diverse in size, ranging from just the Moon.

"This is an example of how the" power "of microchip analysis techniques can be achieved" - Dr. Eduardo Guerras, associate professor of Dai.

"This galaxy is 3.8 billion light-years away, and we certainly have no chance of seeing it directly, even with the most horrifying periscope that people can imagine. " .

"However, we can study them, know their existence, even measure the size, mass and size."

"We analyzed the signals by modeling data, to determine the scale of the planets."

"Science is really great, " Guerras said eagerly.

The study was published by two researchers in The Astrophysical scientific journal.
