Astronomers have discovered an ancient Galaxy, which has led the trail to orbit


The orbits of the Moon, stars of planets orbits, and stars can turn into orbits with galaxies, much smaller than the galaxies, such as orbital galactic nuclei. There are several hangers on the milk line, especially the Big and Small Magellanian Clouds, which depicted two of our galaxy's nude.

Now, thanks to Gaia's data, we have created the most complete map of our sky – astronomers have found another. And it's too big – like the Big Magellan cloud, or about a third of the size of the Milky Way.

In the picture above, this is a dark gloss on the upper left of the image near the Milky Way (bottom left), along with the Big Magellane Virus, depicted on the lower right.

Due to the name Antlia (The Pump), located in the southern stars group, it was named Antlia 2.

So, how can we find Antlia 2, especially since 964 we know about the Large Celery cloud?

There are several ways. The first is hidden behind the milk line. Secondly, it has a very low density, which means that it does not give more light. In fact, it's 10,000 times more than the Grand Magellan cloud, its illustration above is illuminated, so we can see it.

It is one of the longest galaxies. This is not a star – about 100 times the chance to create new stars, with no starless gas than starless, starless galaxies.

This is Paslyand 2 – a remnant of the galaxy. Gabriel Toreleeba, the Academia Sinica astronomer in Taipei, says: "This is a galaxy fragrance."

The group found the galaxy to the Milky Way satellites, based on the star type, called the RR Lyrae Variable. These stars are ancient and metalless poor and are often found in curved galaxies and globular clusters.

According to the name, they are variable stars, that is, about half of the Earth's light changes to a very normal time. This means that at the beginning of the 20th century Henrietta was able to be used as a standard lamp to calculate the exact distance between the Earth and the star found in Levit.

The team found these stars in the Gaia data, but they did not have anything to test for the location of the known objects against the database. Thus, they were further monitored and taken up to about 100 galloping stars before Split-2 was expected to remain within a few months until the sun was hidden.

All the stars they explore are moving along one another, proving that they are already known, the former unknown unknown Antioch, which lies outside the Milky Way.

Based on the team's remarks, Antlia 2 is about 424,000 light years from the Earth and is about 11.2 billion years. Most of the simulation material was packed with milk – Magellan clouds were waiting for them.

"The simple explanation for why today's small mass of 2 ounces is to distinguish itself from the Milky Way Galactic Excitement," said Sergei Koposov, an astronaut at the Carnegie Mellon University.

"However, the larger the size of the object, as a rule, the galaxies lose weight on the waves of the Milky Way, they are smaller, grow."

This means that even if it is to be determined, it will probably be much larger now. There are also some questions about the size of Antlia 2.

As New scientist astronomer and expert of RR Lyrae Jizella Clementin, according to the Institute of National Astrophysics in Italy, the calculation used to determine the distance to the group RR Lyrae was a mistake. It is only 260,000 light years away from them.

However, according to Torrealba, calculations only change the distance between the RR Lyrae stars, but they have researched the red giants, confirming the use of two separate methods.

That is why the RR Lyrae stars are at the front of Antlia 2, meaning the opening of the galaxy is the result of errors and, therefore, very happy, or they are part of the galaxy, but the closest edge.

Anyway, there is no doubt that the team found something strange in our neighborhood.

"Compared to Samyana's 60 or more companions, Ant2 is a handball," says Matthew Walker, astronomer at Carnegie Mellon University.

"We know that this galaxy is just the top of the iceberg, and the Milky Way is surrounded by vast majority of invisible gnomes that resemble it."

The work of the group was accepted Monthly Reminders of the Royal Astronomical Society, and the preprint resource can be read in the archive.
