A study of 543 star-forming clumps in the local universe have allowed scientists to statistically analyze their properties, revealing no evidence of a gradient in clump ages or masses as a function of their galactocentric distances.

New analysis shows that Lyα-emitting galaxies may not faithfully trace the cosmic web of neutral hydrogen; instead, their distribution is likely biased depending on the viewing direction.

New ALMA observations suggest that most of the observable chemistry at 10–100 au is similar for solar-type and M4–M5 protoplanetary disks, but hydrocarbons may be more abundant around the cooler stars.

3.6- and 4.5-μm-band photometry is obtained of 170,000 objects in the Kepler field using the Warm Spitzer Space Telescope, and several stars are identified with large infrared excess.
Jacob Aaron White et al 2021 ApJL 912 L5
Radio continuum observations of Altair have been used to produce the first submillimeter to centimeter spectrum of a rapidly rotating A-type star informed by observations.
