A precursor astrobiological mission could search for putative lifeforms in Venus’s cloud deck using instrument balloons, which could be delivered to Venus via launch opportunities in 2022–2023.

The 774 AD solar proton event, a tremendous increase in proton influx identified in measurements of Japanese tree rings, may have been produced by a single, 1033-erg solar superflare.

The CMZoom survey catalog contains 285 robust (816 total) compact sources in the galactic center. They have effective radii between 0.04 and 0.4 pc and are the potential progenitors of star clusters.

Hubble and Chandra imaging of Barnard’s Star, a 10-Gyr old M dwarf, indicates that quiescent stellar XUV flux does not lead to strong atmospheric escape, but the flare environment could drive significant atmospheric loss.

The cyclical bursts of the young stellar object EC 53 are carefully studied, generating a description in which mass builds up and then drains from the inner protoplanetary disk surrounding the young stellar object.
