Around this And Romeda The galaxy, three small galaxies are not how scientists are expecting.
StewardHubble Space Telescope trained for Andromeda with deep dive when its satellite galaxies were formed and changed over time. What they have received has shown the number of people of small galaxies that do not go around Milky Way.
Some 2,5 million The IS Simple Years Away, these local places formulated a number of their stars. But rather than produced by production, as a computer limit may lift, they continue to make new stars out of stock stock.
“The formation of the star continued to be truly continued in the coming times, which is not all that you can expect in the little galaxy,” Alessandro Savino said in UC Berkeley astronomy, in statement. “No one knows what you should do that so far.”
The little galaxy stopped making stars in billions of years. Then he started.

In the past, scientists mainly write down small galaxies near Milky the way, but they never make sure those were representative of others in the universe. That is why they pointed to a hubble, which is a rotation of the earth, the biggest big galaxy, its viencing of satellite galaxies.
This page readpublished in Astrophysical Journalbased on view from more than 1,000 telescope orbits. The scientific scientific campaign allowed astronomers to form a 36 Dwarf galaxies and rebuild new stars in the 13.8 billion years since big Bang. Photographs gave the unique view of Andromeda bird and place.
Bright light speed
Over the young galarf’s age, scientists were surprised to find that half sitting on the same plane and traveling the same way. However, Meeting and collision often result in things that visit unregulations.
“That is amazing,” said Daniel Weisz, the main investigator at UC Berkeley, in a statement. “It was actually totally surprised to get satellites in that arrangement, and we no longer understand why they seem that way.”
Astronomers learned that galaxies often start small and grow larger by collecting gas and Consolidation and other galaxies. But small thin galaxies that make stars before being called Epoch of Rebooting He never returned to business in the background. Renovate was a period of great change that occurred over more than 13 billion years ago. It could have been when a boy boy was changed for neutral-necked one full of electrons and free protons.
The pictures above give views around the flight of the Andromeda galaxy with its surrounding galaxies, based on hubble data.
Because most of the small galaxies turned away their work that made a star a few thousand years of space, many scientists thought to reset it was the reason. However, some researchers are Calling that idea to the question.
Astronomers blame Andromed with great collision with another dating, perhaps 5 billion years ago. Milky Way, on the other hand, may have never running with a galaxy for 10 to 10 billion. Andromeda’s collision – as well as its great scale – would describe a different and degraded satellite system.
This study only deeper to the group guess that the DWARF galaxies are not always all that are near at home. They can have many different days, investigators send, and it will take a lot of purchases to make sure why.
“Everything spreads in the Andromeda program is the best asymmetric and is visible. It seems that the important thing happens not too long,” said weisz. “Our work has shown that the galaxies with low branches followed different ways of evolution than we know from milky galaxies.”
