Scientists have discovered an alien world, which is 3.2 times more massive than Earth circling Barnard’s Star. Barnard’s Star is a very-low-mass red dwarf. It…
This image of NGC 1333 nebula which was taken by French skywatcher Jean-Pierre Brahic, in December 2011, reveals nebula‘s blue glow.
The reflection nebula is located in the constellation Perseus. A reflection nebula is a cloud of dust visible with the help of energy from a nearby star or stars. These nebula are typically blue in color because the carbon dust particles reflect blue light more efficiently than red light. NGC 1333 is 1,000 light-years away at the edge of a large star-forming cloud. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers). The region is known for containing hundreds of young stars in a chaotic environment of dust and gas. The faint reddish glow comes from hydrogen gas from young stars forming within the nebula.
