Researchers Observe Remnants of Merger between Two Dwarf Galaxies

A stream of stars has been detected in one in every of Andromeda galaxy's outer satellite galaxies, a dwarf galaxy referred to as Andromeda II. Researchers at nuclear physicist Institute aforementioned that it had been indicated by the movement of the celebs that what they're finding out is that the remnant of a merger between 2 dwarf galaxies. it's ne'er happened before once scientists discovered mergers between galaxies of such Mass.

Nicola Amorisco of Denmark's University of Danish capital and also the study leader aforementioned, "Stars during a dwarf galaxy typically move around haphazardly, however this is often not precisely the case for Andromeda II. particularly we tend to might see that a stream of stars is touring otherwise than the remainder in an exceedingly} very coherent way". These stars ar rotating round the center of the galaxy associate degreed have located in an virtually complete ring.

The astronomers have given a theory that galaxies within the early universe were tiny, however grew larger and additional huge as a results of constant collision with neighboring galaxies. Smaller galaxies ar perpetually attracted by giant, huge galaxies attributable to gravity and that they eventually continue to merge along and grow even larger.

It doesn't mean that giant galaxies eat whole of the little galaxies, as a number of them stay in associate degree orbit round the giant galaxy.

Andromeda Galaxy is that the largest galaxy in our cosmic neighborhood and it's concerning two.3 million lightweight years away. Andromeda could be a giant galaxy and enclosed by a swarm of tiny galaxies. it's home to just about a trillion stars and swarm of over twenty much-smaller galaxies orbit it.

Because of close bright constellation constellation, Andromeda Galaxy, or Messier thirty one, will be simply seen within the northwest sky in early evenings in late Gregorian calendar month.
