Scientists have discovered thousands of Source:

Our galaxy “eats” stars of the large and small Magellanic clouds

Our milky Way is going how to eat several more smaller galaxies. Rather, it already does. As the portal , the researchers found several thousand odd stars on the edge of the milky way, they came to the conclusion that stellar objects appeared out of material, resulting in the large and small Magellanic Clouds — dwarf objects, which sooner or later will become part of our spiral galaxy.

Why disappear Magellanic cloud?

Magellanic cloud — dwarf galaxies nearest to our own, which are about 160 thousand light-years from the milky Way. Discovered young stars, most likely, has somehow migrated from the clouds in our margin, strongly spin-off among the “older” stars who live in these parts of the galaxy. Adrian Price-Whelan, researcher, Center for computational astrophysics, Institute of Flatiron in new York, says one of the young stars of the region is very, very far away from us and more vibrant galactic center. In addition, further analysis showed that stars of the Magellanic clouds, apparently, consists of very unusual ingredients, unusual in our segment of the galaxy. So, the characteristics bands of light that reached the Earth, indicate a very low content of metals and heavy elements, which directly indicates the extragalactic origin of the detected stellar objects.

Magellanic cloud — dwarf satellites of the milky Way

Researchers believe it is likely that gas from the hydrogen flow around the Magellanic clouds, at some point passed through our galaxy, creating a powerful pressure at which the gas flow was faced with a similar substance . This pressure, combined with the gravity of our galaxy's pinched part of the Magellanic gas so that it condensed under its own gravity. As soon as it happened, some clumps become dense enough, eventually forming the young and the very light of the stars with no signs of the presence of the usual metals.

The Discovery of non-stars could help scientists find the Magellanic stream in the space, which, as the researchers suggest, is about 90 000 light years from Earth. If the Magellanic stream for some reason is closer, merging and dwarf galaxies can occur faster and earlier than predicted by modern astronomical model. Such an event can significantly increase the lifespan of our galaxy, at the same time adding a large number of new stars in the night sky of our planet is approximately 5 billion years. Unless, of course, the Earth will be able somehow to survive up to this Grand cosmic event.
