New York: Astronomers have discovered a very rare type of galaxy that might provide valuable insights on how galaxies developed during the early days of the Universe.
The galaxy which the astronomers studied is called J1649+2635 and is nearly 800 million light-years from Earth.
It is a spiral galaxy, like our own Milky Way, but with prominent "jets" of subatomic particles propelled outward from its core at nearly the speed of light. Spiral galaxies are not supposed to have such large jets.
J1649+2635 is only the fourth jet-emitting spiral galaxy discovered so far, the first was found in 2003.
“The conventional wisdom is that such jets come only from elliptical galaxies that form through the merger of spirals. We do not know how spirals can have these large jets,” said Minnie Mao from the National Radio Astronomy Observatory in the US.
The astronomers took help from volunteers who are part of an online project called the Galaxy Zoo. The members classify the galaxies as spiral, elliptical, or other types.
To ensure accuracy in the classification, each galaxy image is inspected by multiple volunteers.
So far, some 700,000 galaxies have been classified by Galaxy Zoo participants.
