Astronomers using the Space Telescope NASA "Hubble", opened a surprising new details about the massive, rapidly aging stars, which behaves quite unique for our galaxy way. This star has received the catalog notation NaSt1, and astronomers - the nickname "Nasty 1 "(" intractable ", Eng.), may be a short-term stage of the evolution of supermassive stars.

Open for the first time a few decades ago, Nasty 1 was identified as a Wolf-Rayet star, a rapidly evolving star is much more massive than our sun. This star is losing its hydrogen-rich outer shell with high speed, exposing the red-hot to extremely high temperatures, super bright nucleus of helium.

However, Nasty 1 is not like the typical Wolf-Rayet stars. Astronomers used to observe space telescope "Hubble", expect to see gas in the form of two "interest", originating from the two poles of the stars, like the pattern observed in the case of Eta Carinae, which is a candidate for the Wolf-Rayet star. Based on current estimates, the age of the nebula surrounding the star is a few thousand light years, and it is located at a distance of about 3,000 light years from Earth.

"We were thrilled when they saw a" disk "structure, as it may indicate the possibility of forming a Wolf-Rayet star as a result of the interaction of a binary system," - said Jon Mauerhan the University of California at Berkeley, USA.

Under the proposed scenario team, a massive star evolves very quickly, and as fit to an end of its hydrogen, the star swells. Contact her outer hydrogen shell with the nucleus becomes less strong than before, and the hydrogen shell becomes "dinner" for a nearby companion star falling into the gravitational "claws" of the star. More compact "star cannibal" gradually pulls the matter with the original massive star, the latter loses its hydrogen envelope and reveals the helium core, thus becoming the Wolf-Rayet star.
