Alien Invaders In The Milky Way

Alien Invaders In The Milky Way

A new study, done team of Scientists from Swinburne University of Technology, Australia, has indicated the presence of an ‘Alien Invader’ which comprises of quarter of star clusters in our Galaxy in the Milky Way. It also implies that there could be six dwarf galaxies which are not yet discovered but they are within the Milky Way apart from the Two that have been discovered already.

Professor Duncan Forbes, an Astronomer from Swinburne has shown that many of our galaxy’s globular star clusters have migrated from their birth place elsewhere into our Milky Way, therefore are actually foreigners and aliens to us.. The period could sometime a billion years ago accord to a scientist. Again the Astronomers suspect. Some star clusters contain around one Lakh to Million stars that are alien to our galaxy. It is , but, difficult to pinpoint them.

Professors Duncan Forbes and Terry Bridges examined the star clusters in the Milky Way through Hubble Space Telescope data. Then they compiled a largest ever database of high quality that included data on chemical properties of each of the cluster stars. Professor Forbes opined that we were able to identify key signatures in many of these globular cluster stars that reflect their external origin they belong to. According to Prof Forbes that these.

“Foreign-born globular star clusters actually make up about one quarter of our Milky Way globular star cluster system.. That implies tens of millions of accreted stars – those that have joined and grown our galaxy – from globular star clusters alone.
