Andromeda Galaxy is 3 times the Expected Size

Andromeda Galaxy is 3 times the Expected Size

Our nearest major galactic neighbor in the universe, the Andromeda galaxy has a rotating nebula of stars three times bigger than previously measured. This information was released by a group of American scientists yesterday.

These latest reports have confirmed that we know less about our galactic neighbor than we expected. The group of scientists was represented by Scott Chapman, a researcher from the California Institute of Technology. He presented the results of a survey of Andromeda’s stellar motions at a meeting of the American Astronomical Society.

They used the Keck telescope to measure speeds of 5,000 stars in the outskirts of Andromeda to discover these latest facts. Scott expressed surprise at the fact that these fringe stars are rotating as if they are part of the galaxy’s nebula. The statement said: “Finding all these stars in an orderly rotation was the last explanation anyone would think of.”

The latest findings also claim that nebula is 220,000 light-years in diameter, instead of the earlier estimate of 70,000 to 80,000 light-years.
