NASA and its commercial partners are working on deformable mirrors (DM) that will allow next-generation telescopes to directly observe exoplanets.

The ESA recently conducted a test fire of its next-generation Ariane 6 rocket, a dress rehearsal for its first test flight next year.

One outstanding mystery in astrophysics is known as the "final parsec problem." Simulations predict that binary black holes should stall out in the last stages of their merger. Since we're detecting the gravitational waves from these mergers, we know it happens, but how? A new paper proposes that ultralight dark matter near the black holes could help to carry away orbital energy from the black holes, driving them together.

The Department of Energy just delivered a shipment plutonium that NASA will turn into radioisotope thermoelectric generators (RTGs) for future missions.
