[NEWS] Four space science links: water worlds, debris disks, Alpha Centauri, Kepler 1625 b-i

• Watery worlds orbiting red dwarf stars, in one scenario, tend to see their volatiles evaporate into space quickly.


• Gaps in debris disks orbiting young stars seem to point to the existence of planets in these gaps.


• The proposed Project Blue--a space-based telescope capable of imaging planets at Alpha Centauri--sounds good to me.


• Kepler-1625 b-i, a strong candidate to be the first exomoon found, seems to have a fascinating history.
