Sunny side serves massive stars

Researchers at the European Southern Observatory have discovered a huge, sunny side after top egg in space.

The fried egg - a massive star, surrounded by a double, the next yellow Hypergiant star neighboring Earth finds outer ring of gaseous dust - up today. Yellow hypergiants are rarely, massive stars living in a phase of the life cycle of a star, which only takes usually a couple hundred thousand years - a Flash in the life of the Galaxy. You consume a lot of energy to burn so bright.

Dust clouds surrounded the entire body of the Nebula - a yellow Hypergiant "Yolk" "Protein" - located about 13,000 light years from Earth.

"This object had glowing bright above noticed people, but nobody had identified it as a yellow Hypergiant," astronomer Eric Lagadec says, to examine part of European Southern Observatory team that discovered the monster star, while the neighboring stars.

The Nebula is massive: it has a radius of 10,000 times the distance from the earth around the Sun. For scaling, you would provide the Centre of the Nebula in the center of our solar system - the Sun - then the outermost part of the Nebula would reach star Jupiter. Of the regions in outermost part of the Nebula would some gaseous rings orbit Comet Neptune span.

The infrared photographs Lagadec and his colleagues in the fog with heavy duty telescope, used, to capture images. Above the photo shows the bright, shining star embedded in the middle of two outer shells of cosmic dust - gases the whole galaxy.

The outer rings of dust are the remains of the earlier explosions, has been through the star as it dies. Finally, the star in a supernova event, which all start his gaseous matter in the universe will explode. And when that happens, it is probably as bright as Venus lights and visible during the day, says Lagadec.

He says "It could happen tomorrow or in a few hundred thousand years".

This research was approved publication by the journal astronomy & Astrophysics.
