Astronomers have discovered a new dwarf galaxy that’s a satellite of the Milky Way. In size it’s a lot more other similar systems of similar luminosity.
About it reported in a press release on Physics.org.
The researchers conducted a research for satellites of the Milky Way, analyzing astrometric and photometric information obtained using the space telescope Gaia. The new galaxy, that is a large compared to the other dwarf stellar systems of similar brightness, was named the galaxy of Pump two (Ant 2). Its existence was confirmed by observations using a spectrograph 2dF+AAOmega on the Anglo-Australian telescope.
Ant two is at a distance of 424 thousand light-years from Earth, its age is 11.2 billion years old. Its radius reaches around 9300 light years, making it as giant as the giant Magellanic Cloud (LMC). However, the luminosity ant two in four thousand times smaller. in addition, the galaxy Pump two about a hundred times more broken than ultradilute galaxies with low luminosity and a small range of stars at larger sizes.
We will remind, well-known in Rostov blue “Lada” with creative tuning got in an accident. On Union street near the monument to Strike with UFO sedan crashed into a pickup truck.
