Are these planets?

Under review


Sorry for the delayed reply. This effect is most likely instrumental and due to the fact that GALEX was looking at an extremely bright star in the ultraviolet (alpha Andromedae, a massive 'blue' star, with spectral type B8 and a companion binary star with spectral type A3, seen as the smaller orange circle to the right). The GALEX mission was not designed to have the sensitivity to be able to detect planets. 

Best regards,

Deborah on behalf of the ESASky team
