A survey of the Messier 17 HII region turned up nearly 200 radio sources — more than in comparable regions — at least 40% of which are associated with emission from stellar coronas.
Near-infrared observations enable discovery of black hole candidates in galaxies without bulges, and the derived masses of these black holes are in line with what is expected given the stellar masses of the galaxies.
New laboratory work has determined the infrared spectrum of a type of nitrogen-containing ice that is found in Titan’s atmosphere and may also be present on other solar system bodies as well as exoplanets.
New observations reveal the structure of 12 planetary nebulae, but determining the cause of their unusual morphologies — and whether they are related to the evolution of their central stars — requires further work.
Though black hole binaries can contain two primordial black holes — those thought to have formed in the very early universe — black holes found in tandem with neutron stars are unlikely to have a primordial origin.
Extremely detailed images of RY Tau suggest that the young star ejects knots of material at an irregular cadence and at significantly shorter intervals than other stars, which may be related to its mass accretion rate.
