Caption
This is a James Webb Space Telescope view of a 100-billion-mile-wide disk of dust around the star Vega. The disk is remarkably smooth and there is no debatable evidence for planet formation taking place. Webb resolves the glow of warm dust in a disk halo, at 23 billion miles out. The outer disk (analogous to the solar system’s Kuiper Belt) extends from 7 billion miles to 15 billion miles. The inner disk extends from the inner edge of the outer disk down to close proximity to the star. There is a notable dip in surface brightness of the inner disk from approximately 3.7 to 7.2 billion miles. The black spot at the center is due to lack of data from saturation.
