The molecule cyanomethyl (CH2CN) was previously detected around protostars and in pre-stellar cores and molecular clouds, but recent observations place the molecule in a new location: protoplanetary disk TW Hydrae.

Metallicity of star-forming clumps decreases as you move farther from the parent galaxy disk, bolstering the idea that the metal-rich interstellar medium mixes with the metal-poor intracluster medium in pressure-stripped clusters.

Follow-up observations validate the existence of a planet orbiting the M dwarf KOI-4777 that is roughly the same size as Mars and no more than three times as massive, making it the smallest known ultra-short-period exoplanet.

A team has explored the origins of fireballs detected by the Desert Fireball Network and found evidence for ongoing fragmentation of the parent bodies responsible for the Taurid Complex meteor showers.

The diversity of classical novae is reflected in their radio observations, which reveal a mixture of thermal emission and synchrotron emission — radiation generated when charged particles spiral around magnetic field lines.

The possibility of life being seeded by impacts from another star system varies wildly depending on where you are in the galaxy, but the probability of life arising via panspermia rather than prebiotic evolution tends to be low overall.
