Astronomers have discovered the smallest Galactic Galaxy that is bordering the nearest galaxy of the Milky Way and Romeda Galaxy.
Galaxy-bitsy satellite is called Andromeda XXXV and is located about 3 million years from Earth. The discovery of galaxies helps astronomers to have useful comparison tools for the study of the Galactic Galactic Galaxy. The team's research results are Published This week in the journal Astrophysical Journal
“These are galaxy that works completely. But they are about one million in the Milky Way. “Eric Belle, Astronomy from the University of Michigan and the senior author of a university in a university in a university release– “It's like having a perfect human being, which is the size of rice.”
Andromeda xxxv is only about 20,000 times larger than our sun, even the Galaxy. For the comparison of the Milky Way is about 1.5 trillion mass And the best galaxy can have up to 30 trillion mass of solar mass
Although it is a full galaxy, the Andromeda XXXV is small enough to be pulled with gravity. Andromeda-Much Like the acidic galaxies of the Milky Way Researchers observed andromeda XXXV with Hubble Space Telescope.
“This type of galaxies can be discovered around a single system of the Milky Way in the past,” Belle said. “Now, we can watch around Andromeda and for the first time we do that outside our system.”
Observing hubs, revealed that not only Andromeda XXXV, the Galactic Galactic But still small enough to ask questions about the said satellite
“Most Milky Way Satellite has a very ancient star population. They stopped the stars about 10 billion years ago, “said Margaria. “What we see is a similar satellite in Andromeda. Can create stars up to a few billion years ago – about 6 billion years.”
This finding can be used to make a difference in the galaxies and the formation of stars in the Milky Way from the conditions in other galaxies. 100 billion to 2 trillion galaxy In the universe that can be observed But the small galaxy is hard to see – when you hear about the observation of the Andromeda XXXV's hub
There is still a distinctive question about a small galaxies -how can survive from the universe almost 13 billion years ago? “All the universe became a bowling oil tank,” Belle said and Andromeda XXXV is so small that it may lose all gas. But after billions of years, after that, the galaxy was still forming a star.
Additional observation can clarify the characteristics of this industry. The existing satellite – and the proxse can shine on the galaxies, the academic surface rotates around the outside of our own universe.
