Astronomers have found the cause of the Magellanic Stream





Astronomers have finally been able to determine the cause of the Magellanic Stream – a giant stream of gas that almost half goes around our galaxy. Early attempts at computer simulation showed that the source of this gas is the Small Magellanic Cloud (SMC) – one of the dwarf galaxies, which is adjacent to our galaxy, the Milky Way . The new study has not only confirmed, but also pointed out that the second important element in the formation of the Magellanic Stream is the Large Magellanic Cloud (LMC), another dwarf galaxy.

This discovery helped to make the space telescope “Hubble” by which scientists have found that most of the gas constituting the Magellanic Stream, separated from the small galaxy about two billion years ago. But then it turned out that a lot of time later stood and gas from the Large Magellanic Cloud.


Evidence of this was the discovery of scientists low oxygen and sulfur, which is close to what was found in the IMO, part of which is allocated 2 billion years ago. The very same high concentration of sulfur scientists found at the junction of two dwarf galaxies, which would indicate that the gas of which stood out much later than the time taken than was previously thought.

” By studying the heavy elements contained in this field, we crept up to the Magellanic clouds, where the heaviest concentration of these elements has increased dramatically, “- says Andrew J. Fox, the lead researcher, who made ​​this discovery.

“This inner region was very similar in composition to the composition of the Large Magellanic Cloud, which tends to suggest that this part of the galaxy was literally ripped from BMO Small cloud.”
