Massive Peculiarly Dim Galaxy Discovered Concealed On Far Side Of Milky Way

Earth might soon collide with

While low in mass, Ant 2 is about the same size as the Large Magellanic Cloud (LMC).

The University of Cambridge wrote that the galaxy is either far too large for its luminosity or far too dim for its size. "Normally, as galaxies lose mass to the Milky Way's tides, they shrink, not grow", Koposov said.

The team tried to get more data on Ant 2 via the Anglo-Australian Telescope in Australia. In a paper presented at the online library of preprints arXiv.orgscientists describe 2 Antlia (Ant 2) as a small galaxy,"Ghost", unique among about 60 companions of the milky Way.

Scientists at the University of Zaragoza in Spain detected the dark matter hurricane using data from the European Space Agency's Gaia satellite. As structures emerged in the early Universe, dwarfs were the first galaxies to form, and so most of their stars are now old, relatively low in terms of their mass, and poor in metals.

ERA's Gaia Mission has proved to be a great asset for astronomers worldwide, due to data provided by Gaia, researchers worldwide have been able to catalog more than 1.7 billion stars with precise details about their size and measurements.

Massive amounts of data are generated by orbiting scientific platforms like the Hubble, and the ESA's Gaia satellite; so much data that it often takes years for researchers to pour through.


"RR Lyrae had been found in every known dwarf satellite, so when we found a group of them sitting above the Galactic disk, we weren't totally surprised", said co-author Dr. Vasily Belokurov, researcher at Cambridge's Institute of Astronomy.

In April previous year, a team of astronomers found that stars in the vicinity of the Solar system are moving in the direction opposite to the direction of rotation of our galaxy, writes National Geographic.

They were able to measure the spectra of more than 100 red giant stars just before the Earth's motion around the Sun rendered Ant 2 unobservable for months.

Adding heat to the outlandish apocalypse claims surfacing all around the internet, a team of astronomers has suggested that an incredibly fast dark matter hurricane will soon slam into the earth as it moves through the Milky Way. Past research has proposed that a few smaller people could be swelled by vigorous star arrangement, making the cosmic system "puff up", yet the new research demonstrates that this process would need to be strikingly proficient to clarify Ant 2.

"What remains unexplained, however, is the object's giant size". In addition, now the milky Way absorbs dwarf elliptical galaxy with a diameter of about 10 thousand light years.

Co-author Dr Alex Geringer-Sameth, from the Department of Physics at Imperial College London, said: "Antlia 2 might be hinting towards some new fundamental forces at work - in particular that dark matter might not behave as simply as has been assumed in the standard model of cosmology". The analysis also allowed the researchers to predict which possible signatures of the stream scientists ought to look for to find dark matter.
