Astronomers: Galaxy last supernova

Keywords: astronomers Galactic Supernova

A team of international astronomers 14, reported that they found the Galaxy known recent supernova that occurred in about 140 years ago. Astronomers have known that this discovery of the Galaxy to the future of Supernova frequency is extremely important. World Science report

From the United States, Britain and other countries of astronomers in the report, they make use of NASA's Chandra x-ray space telescope and the United States "a great array of" radio telescope, the track to the supernova remains the expansion of the material to the calculated time of supernova in about 140 years ago. Prior to this, within the Milky Way Galaxy known last supernova explosion occurred in 1680.

Massive stars death when the violent collapse of a supernova explosion, astronomy community think Supernova blast out in considerable material diffuse in galaxies, a breed a new generation of stars and planets around the original material. World Science report

The detection of a supernova explosion place too close to the center of the milky way, there is full of gas and dust, which makes its brightness only normally supernova of one trillion minutes, with no optical telescope observations. The Chandra Observatory project leader, United States, North Carolina State University, Stephen · Reynolds explains that many Supernova using optical telescope can be observed, "but if it is too dark, even though the supernova in our Galaxy ' own backyard ', will be missed."

Astronomers in other galaxies frequently observed supernova, they speculate that the Milky Way Galaxy, probably every 100 years should have 3 supernova. "Very large array," observing the Project Director, Cambridge University astronomer David · Green said: "If this estimate is correct, 1680, you should have about 10 times a supernova, today, we finally succeeded in tracing into one. ”

Astronomers believe that this discovery will help people learn more about Galactic supernova in the milky way stars at a frequency of awareness from death to the rebirth of cyclic process, etc. World Science report
