Infrared Space Observatory Herschel owned by European Space Agency (ESA) has detected the movement of wind consisting of gas molecules that flow away from the galaxy.
The wind that has been monitored for many years was thought to have sufficient power to destroy the galaxy consists of gas and halt star formation early on.
Herschel detected the wind is incredible. Some blowing hard, with a speed of more than 1,000 kilometers per second. The wind is 10 thousand times faster than the storms that blow on Earth.
"This is the first time that such molecular gas flow can be clearly observed in a galaxy," Echard said Sturm, a researcher from the Max-Planck Institute, who chaired the study, as quoted by the Daily Galaxy, Wednesday, May 11, 2011.
This finding, Sturm said, is important because the stars are formed from molecular gas. While this wind flow steal materials belonging galaxies needed to make new stars. "If hembusannya strong enough, they can even stop the total star formation," he said.
"With Herschel, now we can study what effect the wind is blowing towards the evolution of galaxies," said Sturm.
From the research, concluded that up to 1200 times the mass of our sun is lost every year due to the devastating winds. The amount is equal to the depletion of gas supplies to form a galaxy of stars between one and 100 million years into the future. In fact, the disruption of star formation has adverse effects on galaxies.
The wind itself could be due to the expenditure of particles and intense light of a new star or it could be by the shock wave from the explosion of an old star. Alternatively, the wind can be triggered by radiation caused by substances that are spinning around the black hole, in the middle of the galaxy. (Eh)
