An international discovery, with an Israeli researcher partner
Computer artist's illustration depicting a young star cluster surrounded by the gaseous (ring) bubble with an inflating bubble around the nebula
An international team of researchers - in which Israel was also represented - located in the depths
The universe, a very energetic and inflating gaseous bubble, associated with a star cluster
Huge dimensions. It is estimated that the bubble was formed as a result of a combination between
A stellar wind (like the solar wind) that compresses gas and originates in a star cluster
Young and hot - and the attraction of very massive stars. Staff
The astronomer announced that he had detected supersonic movements in the nebula
surrounding the studied star cluster.
The report on the discovery was given at the annual conference of the American Society
for astronomy which was in Pasadena, California. Dr. participated in the research team
Sarah Beck, from Tel Aviv University. The discovery was made possible thanks to use
In infrared equipment at the giant "Kek" telescope in Hawaii.
The researchers said that it has long been known that small gaseous bubbles are around
Young and very hot stars, in our galaxy - called the Milky Way.
But the bubble that has just been discovered is many times more energetic and possessive
Potential to severely damage the parent galaxy, adjacent to it.
The speed of the stellar wind that causes the bubble to swell is 4500 km per hour,
in the right gas cloud. This is a powerful spirit that was not known until now
So much for science.
The studied galaxy is "only" 12 million light years from us, in the group
The stars Centaurus. The studied star cluster contains a million stars
Very young, most of them are hidden from the "eyes" of any optical device, due to the gas cloud
The glow and dust that surround him.
The researchers estimated the age of the stars in the studied cluster at 15 thousand years.
For the Milky Way, the age of the star clusters is estimated at billions of years.
