uranologist at the International Centre for Radio Astronomy Research have discovered a beetleweed with a rather remarkable feature — a monolithic plume of gas measuring 300,000 calorie-free - class across . That ’s five times the length of the beetleweed itself .
Located in the Virgo Cluster , galaxy NGC 4569 is located 55 million light - years from our own Milky Way . Scientists have known about this unusual spiral galaxy for many years , but they could n’t explicate why it contains less gasolene than it ’s theorize to . An outside team of astronomer led by Alessandro Boselli at the Laboratoire d’Astrophysique de Marseille in France last have the answer : The galaxy is moving so tight — about 745 international mile per 2nd ( 1,200 km / s)—that the result force per unit area is stripping it of its hydrogen .
“ We did n’t have the smoke gun for hire , the clear evidence of lineal removal of gas from the galaxy , ” notice Boselli in astatement . “ Now , with these watching , we ’ve see a huge amount of gaseous state that creates a flow trailing behind the galaxy for the first time . What ’s very nice is that if you measure out the volume of the stream , it ’s the same amount of gas that is missing from the galaxy ’s disc . ”
Boselli said that big clusters pin down a lot of raging throttle , but when a galaxy enter a bunch , all the gather insistency cartoon strip affair away from the galaxy . Astronomers call it a “ Aries pressure divest event . ” In this case , extragalactic nebula NGC 4569 has been stripped of 95 percentage of the natural gas required to fuel the formation of fresh stars . So for all purport - and - purposes , this wandflower is utter . The trail of ionise gas is about 80 kiloparsecs across , or 300,000 light - class . That ’s five clock time the length of the wandflower itself .
The research worker were able to make the breakthrough using a tiptop - sensitive camera called MegaCam on the Canada France Hawaii Telescope . The details of this workcan now be foundin the journal Astronomy & Astrophysics .
