Rocky debris around Vega. Artwork of the ring of rocky debris orbiting the star Vega. 25 light years distant,Vega is the brightest star in the constellation Lyra and the fifth-brightest in the sky. It debris disk is thought to be composed of dust particles and asteroid-like objects. The origin of the disk is not certain. It may have formed from material left from the formation of the star,or from a later collision between protoplanets. The structure of the debris disk has been examined in infrared by the Spitzer Space Telescope and the Herschel Space Observatory. The SST observations revealed a more extensive disk structure than previously known. Image published in 2013 | |
