Searching for Planets Around Vega: A Summary of JWST Observations

Astronomers used the James Webb Space Telescope to search for planets around Vega, a star known for its prominent debris disk. While they detected two distant objects, these were likely extragalactic sources, not planets. The study set strict limits on the possible sizes of any planets in Vega’s system, ruling out planets larger than Jupiter within 10 AU. The smoothness of the debris disk suggests that any planets present are likely smaller than 0.3 times the mass of Jupiter.
