The existence of Cosmic Dust in the Universe

The existence of Cosmic Dust in the Universe | New

Cosmic dust was also recycled by the universe. The resulting cosmic star dust then blown by the solar wind from the stellar explosion. Dust was then recycled in interstellar space and forming gas clouds / nebula which can then again be the star formed. For the cosmic dust

SN2010jl supernova, Supernova At least I've found

SN2010jl supernova, Supernova At least I've found | New

  Observations made with NASA's Chandra X-ray Observatory, provides new evidence that the shock wave generated by the supernova is able to penetrate a collection of gas around a star that exploded. This discovery may help astronomers know the why some explosions

supernova supernova stronger than others.

On 3 November 2010, a supernova was found in galaxy UGC 5189A, located 160 million light-years from Earth with TODD data from the All Sky Automated Survey Telescope in Hawaii.

Composite image of UGC 5189A shows X-ray data in purple and optical data from Hubble telekop in red, green, and blue. SN 2010jl is the top of the galactic X-ray light is very bright.

Quoted from spacedaily.com, Tuesday (22/05/2012), The research team used NASA's Chandra X-ray Observatory to observe this supernova in December 2010 and October 2011. This supernova is one of the brightest supernova of other supernova ever detected by X-rays.

With optical light, SN 2010jl 10 times brighter than other types of supernova that resulted from the explosion of massive stars. And it goes into the brightest supernova group that is currently known by the optical survey. Different explanations proposed to explain the supernova energy including supernova blast wave interaction with matter density around the star will explode. Radioactive resulting from instability of the supernova (dipisu by the conversion of gamma rays into particle and anti-anti-particle), and the emission from the core of the star with a strong magnetic field which is not unusual.

Data retrieved from NASA's Chandra X-ray Observatory shows that the X-rays from the supernova blast wave is absorbed by the surrounding gas collection. And collection of the gas comes from the star is still before he explodes.

Mars Asteroid Hit 200 Times a Year | New



NASA recently revealed that the planet Mars was more frequently hit by asteroids and comets than previously thought. Mars was hit by asteroids many as 200 times each year. The average asteroid that hit the planet measuring 1-2 meters.
