NGC 604, a stellar nursery seen through X-rays

About 3 million light-years away in the vicinity of the spiral galaxy M33, the vast stellar nursery NGC 604 has about 1,300 light-years across, about 100 times the size of the Orion Nebula.

The blue areas of the image are hot gas. In fact, among the regions of star formation in the Local Group of galaxies, NGC 604 is the second largest after 30 Doradus, also known as the Tarantula Nebula in the Large Magellanic Cloud.

This color composite X-ray data (in blue) from the Chandra Observatory and Hubble optical data, we show that the bubbles cavernous NGC 604 and its cavities are filled with tenuous hot gas emission X-ray

is fascinating as well as such that NGC 604 is divided by a wall of gas relatively frío.Al west side (right) of the nebula, the data tell us that the material is heated to X-ray strong winds from a cluster of about 200 young, massive stars.

the east side filled cavities appear to be more X-rays old, suggesting that supernova explosions in the end of the evolution of a massive star, have contributed to its formation.

Found earthquakes on the surface of massive stars

Valencia

Astronomers have detected photometric images provided by the Corot satellite motion in the area of \u200b\u200bmassive stars, those that are much larger than the sun and rotation quickly, which will improve the knowledge of the internal structure of the major stars of the Universe.

analysis of CoRoT data is done using mathematical and sophisticated computer, some of which have been developed at the Astronomical Observatory of the University of Valencia.

The results of this research was presented this week CoRoT Congress 2009, held in Paris, the international meeting on the CoRoT mission organized after the satellite launch, December 2006.

Scientists can not access the interior of stars, only have the ability to observe its surface. Therefore, to deepen the knowledge of the structure of stars, the astronomers analyzed the so-called beats, which, like earthquakes on Earth is the only way to get to know more details of its inner part. The stars may change size and shape.
