ALMA observations reveal details of the rotating, high-velocity jet associated with the FIR 6b protostar located in the Orion Molecular Cloud-2, which may be influenced by a magnetized accretion disk wind.
Camilla Scolini et al 2021 ApJL 916 L15
New numerical simulations explore the possibility of analyzing the interaction of coronal mass ejections with solar wind streams using a swarm of radially aligned, simulated spacecraft.

The second discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) program, COCONUTS-2b, is the second-coldest (434 K), second-widest-orbit (6,471 au), and nearest (10.9 pc) exoplanet imaged to date.
