When the stars “sneeze”
Photo of the day | When the stars “sneeze”
Operators Space Center, responsible for managing the space telescope “Hubble” , published a new and very interesting picture of the Herbig-Haro objects, parts of nebulae associated with young or not yet fully formed stars. One of the main features of these sites are huge in terms of gas emissions that can be seen just in the picture above.
Object of focus in this picture is located in the center. Photo captured at the moment of release huge volume of hot gas, which is being carried out with great speed away.
“So sneeze Star” – joking astronomers.
Events culprit in this case is a variable star (its brightness varies with time) V633 Cas, for which in the recent past had seen “Hubble.” Telescope space agencies NASA and ESA (European Space Agency) showed that gas clouds ejected star, moving at a speed of several hundred kilometers per second, creating a powerful shock wave and pushing their way located on a static gas field. It is interesting here is that this Herbig-Haro object is formed into a star the size of our Sun, which means that its main life cycle will run for about 10 billion years.
By hypothesis, scientists, about a hundred years later the star V633 Cas reaches its full maturity. During this period of her life she will begin to burn hydrogen and thus begins his star cycle.
Back laser transmission system information showed very high efficiency
Next culprit low sales of the smartphone is the LG G2 Nexus 5
