80 possible exoplanets discovered by Kepler space telescope

Surface molecules reveal ‘invisible’ exoplanets

There are several gaps in the gas surrounding the star which could have been created by planets passing through

ALMA discovers trio of exoplanets

An image of the newborn planet and its host star. The dark circle at the centre is a mask that blocks the light of the central star so astronomers can see the fainter disc and planet. The planet is the bright spot to the right of the black circle. Image Credit: ESO/A. Müller et al.

121 exoplanets may host ‘habitable’ moons
