New fits to the photometry of 58,461 galaxies from the 3D-HST catalogs at 0.5 < z < 2.5 imply an older, more quiescent universe than found by previous studies at these redshifts.

Simulations of instrument performance show that ESA’s Ariel, a space telescope planned for launch in 2028, may be able to characterize the atmospheres of ~2,000 known and predicted TESS exoplanets.

The extremely slow spin of the slowest isolated pulsar, 1E 161348−5055, was likely caused by interactions with a supernova fallback disk that surrounds it; the spin rate can be used to estimate the mass of the disk.

New ALMA images of a quiet-Sun region reveal the presence of distinct particularly dark/cool areas in the millimeter maps with temperatures as low as 60% of the normal quiet Sun.

A curated data set (encompassing 6.5 TB!) from the NASA Solar Dynamics Observatory mission is presented in a format suitable for machine-learning research in heliophysics and the physical sciences in general.
Yuhu Miao et al 2019 ApJ 877 61
Observations of NOAA active region AR11166 reveal that the appearance of a satellite sunspot led to recurrent solar blowout jets, 30% of which directly developed into coronal mass ejections.
