Over its 6.5-yr lifespan, the proposed infrared space-based telescope Sentinel will be able to discover 50% of all objects >40m that have the potential to impact Earth. It can find 70% when combined with LSST.

The citizen science project Disk Detective was used to discover a new M-dwarf debris-disk candidate in the ~45 Myr old Carina association. This discovery could help us understand the evolution of such disks.

K2-56b, an exoplanet recently discovered with the K2 mission, orbits a solar analog and has 2.23 times Earth’s radius — but a surprising 16.3 times Earth’s mass, raising questions about its composition.
