APS physics had different statements, and one of them pointed out that these stars were supposed to be the remains of the arcade galaxy that have been disappearing from the Milky Way galaxy a few billion years ago.
The discovery of Antlia 2 is challenging the current models of the formation of the galaxy. Named Antlia 2 (or Ant 2), the galaxy is extremely poor, but it lies about 130,000 light-years away from our galaxy.
A global team, including many astronomers from the University of Cambridge, has discovered a worse galaxy in the study of Gaia's telescope data.
However, despite its size, Antlia 2 gives little light. One of the reasons why this vast galaxy remained hidden for so long to give a little light; Ant 2 is 10,000 times lighter than the Great Magellanic Cloud. Researchers at Universidad de Zaragoza, King's College in London and the Astronomical Institute in the United Kingdom studied the starry currents that the spheroidal sphere of the spheroidal galaxy, flooded by the Milky Way, was behind.
A group of astronomers added heat to the external demands of the apocalypse that were occurring all over the world. He will suggest that an incredibly fast dark material will quickly penetrate into the earth as it moves along the Milky Way.
The ESA Mission Gaia has provided the most extravagant list of stars, including high precision estimates of nearly 1.7 billion stars and the discovery of incomprehensible points of interest of our home. Because structures appeared in the early universe, the first galaxies that formed, so most of their stars are old, low-fat and bad metals.
They were lucky, in fact, because in 2017, a star stream called S1 was discovered by the European Gaia satellite. At the beginning of this year, the second set of data obtained by Gaia is released to scientists from different countries, a new set of data provides information on the details of the Milky Way that were not available for study earlier.

Precise measurements Gaia provided researchers with data on RR Lyrae stars that had a bad metal, a type of small, ancient star that regularly pulses and changes its brightness every 12 hours, reports Astronomy Now.
Then again, the properties of the complex "dark matter"which is supposed to bring together the worlds could be examined.
"This is the spirit of the galaxy," said Gabriel Torrealba, lead author of the discovery that was released on November 9th.
Ant 2 is probably stretched out with the galactic tides of the Milky Way, which is much lower than expected for the object of its size.
What remains unexplained is the large size of the building, says astronomer Sergei Koposov at Carnegie Mellon University.
"Compared to the remaining 60 or more satellites in the Milky Way, Ant 2 is weird," said co-author Matthew Walker, an assistant professor at Carnegie Mellon University. The current theory that requires it dark matter is closely packed in the centers of the galaxies, it does not appear to refer to a newly discovered ghostly scapegoat. "We wonder if this galaxy is just the tip of the iceberg."
