Solopos.com, Jakarta – Using data from the European Space Agency (ESA) telescope GAIA, astronomers have discovered a very mysterious new dwarf galaxy near the Milky Way. This galaxy is called a ghost galaxy because it is hiding in the universe so far but its low density makes it very difficult to detect.
Named Antia 2 or simply Ant 2, the Galaxy's mass is estimated to be 1/3 of the Milky Way, but is very dark and hiding in a region known to the astronomers as the zone of Avoidance (Zoa). The size of the galaxy is also comparable to the Great Magellanic Cloud, one of the two largest dwarf galaxies that embrace the Milky Way but 10,000 times dimmer.
The Giant but Dark Objects As Ant 1 have never seen before our discovery is merely thanks to the quality of data from Gaia, "said Gabriel Torralba, lead author of the study of Cambridge University as reported Suara.com, Wednesday (11/21/2018).
Reporting to IP Science, Ant 2 is located at a distance of about 130,000 light years of the Milky Way and more than 13 million times more massive than the sun. The cause of the dwarf galaxy is very dark because the 2 is not filled with normal matter, but is dominated by dark matter, where the material has not been identified. In addition, Ant 2 also has only a few stars.
"We're wandering if this galaxy is the only one or perhaps the Milky Way is surrounded by invisible galaxies such as this," added Matthew Walker, one of the astrologers involved in the study.
According to the astronomers, compared with 60 other Milky Way satellite galaxies, Ant 2 is the most eccentric. Although the current theory can not yet explain this mysterious ghost galaxy, the astoniers continue to study it.
