In August 1872, amateur astronomer Henry Draper selected Vega as the first nighttime star to have its spectrum photographed. Draper's image revealed the classic absorption lines of hydrogen known as the Balmer series. This step-like sequence of lines results when electrons in a hydrogen atom located at higher energy levels drop down to level 2, the...
Like the Sun, Vega burns hydrogen in its core, but because it's hotter and more massive, it will exhaust its energy reserves sooner. At present, the star is about 455 million years old. Vega will leave the main sequence in about 500 million years and bloat into a red giant before expelling its atmosphere and evolving into a white dwarf encircled by...
While Vega may host an as-yet-unconfirmed Neptune-size planet, we have definitive proof of a dusty debris disk surrounding the star that's likely composed of an amalgam of silicate and carbonaceous grains. The rubbly ring may be home to protoplanets in the rough-and-tumble process of becoming full-fledged planets or the dusty aftermath of alarge an...
