Scientists have discovered a doughnut-shaped galaxy 11 billion light-years from Earth,media BGR reported. The galaxy is making stars at an alarming rate. The researchers believe its shape was formed by a collision with another galaxy. The findings were recently published in the journal Nature-Astronomy.
The galaxy, called R5519, is 11 billion light-years from Earth. “This is a very strange object that we have never seen before,” Dr. Tiantian Yuan, lead author of the study, said in a statement. “It looks strange and it’s familiar at the same time. “It is making stars 50 times faster than the Milky Way. Most of the activity takes place on its star ring — so it’s really a ring of fire. “
As for how it formed, the researchers believe it did not form a ring galaxy at all. Some ring galaxies appear to have formed on their own without outside influence, but R5519 is not. The researchers believe this is a rare “collision of ring galaxies.”
“In the case of this ring galaxy, we look back to the early universe 11 billion years ago, entering the era when the thin disk was just ‘assembled’,” study co-author Kenneth Freeman said in a statement. “By contrast, the thin disks of our Galaxy began to ‘assemble’ about 9 billion years ago. The discovery suggests that the disk ‘assembly’ in spiral galaxies occurred at a time older than previously thought. “
