The satellites of the National Administration of Aeronautics and Space ( NASA , for its acronym in English), ground-based telescopes and theoretical modeling have captured spectacular images of the star system Eta Carinae , the most luminous and massive than has been discovered in our galaxy.
Eta Carinae is a binary star, two stars orbiting over a period of more than five Earth years, comprising a aged between two and three million years, which is very little in cosmic terms, variable rate hipermasiva light blue, in the constellation of the keel. Its mass is between 100 and 150 solar masses, belonging to the most massive stars known in our Galaxy.
The star system is located inside the Homunculus Nebula . Its mass makes it highly unstable and prone to violent ejections of matter. So many astronomers believe that a powerful supernova (or hypernova) will end his life within a few hundred thousand years.
You have reported Goddard astrophysicist and lead author, Ted Gull thanks to these images the scientific community hopes to better understand the state and its current environment. Mystery solved are still seeking explanations of eruptions that take place in it, besides confirming their future.
In the picture we can see the system of two stars, together with the remains of ancient eruptions that form the Homunculus nebula around the star.
Many media have created hype around the star will be in not long scene of a tremendous explosion, which because of its proximity to our planet (just about 7000 light years) constitute one of the most spectacular events in the history of astronomy.
Coincidentally, today the robot Opportunity , which was sent to Mars in 2004, has us made another interesting photograph of astronomical nature of the Martian surface. Another interesting event for the remaining weeks is the arrival of a large asteroid.
