20 It discovered the origin of the Magellanic Stream
, a long ribbon of gas stretching nearly halfway around our Milky Way.
Both the Large and Small Magellanic Clouds are very likely newcomers to the Milky Way's environs, and both are wreathed in a stream of hydrogen gas (the Magellanic Stream
) that winds around our galaxy.
The evidence for the findings comes from a lacy filament of hydrogen gas called the Magellanic Stream
. It trails behind our galaxy's two small companion galaxies, the Large and Small Magellanic Clouds.
The proof comes from a lacy filament of gas, mostly hydrogen, called the Magellanic Stream
and this trails behind our galaxy's two small companion galaxies, the Large and Small Magellanic Clouds.
For instance, it's not clear what pulled the Magellanic Stream
, along tail of hydrogen gas, out of the two clouds.
New observations might reveal the origin of the Magellanic Stream
, a long rivulet of gas encircling the Milky Way that is headed by the Small and Large Magellanic Cloud dwarf galaxies.
Fox of the Space Telescope Science Institute in Baltimore, Md., and the European Space Agency, determined the source of the gas filament by using Hubble's Cosmic Origins Spectrograph (COS) to measure the amount of heavy elements, such as oxygen and sulfur, at six locations along the Magellanic Stream
. COS observed faraway quasars whose emitted light passes through the stream and detected these elements from the way they absorb ultraviolet light.
Washington, Aug 9 ( ANI ): Astronomers have unraveled a 40-year mystery on the origin of the Magellanic Stream
, which is a long ribbon of gas stretching nearly halfway around our Milky Way galaxy.
The LMC tidally yanked gas from the SMC during that close encounter, forming the Magellanic Bridge, while Milky Way tides helped stretch that gas into the Magellanic Stream
and Leading Arm.
The new revelations provide a fresh insight on what started the gaseous intergalactic streamer.The first evidence of such a flow, named the Magellanic Stream
, was discovered more than 30 years ago, and subsequent observations added tantalizing suggestions that there was more.
Visible in the Southern Hemisphere, they are much smaller than our Galaxy and may have been distorted by its gravity.idever and his colleagues observed the Magellanic Stream
for more than 100 hours with the GBT.
