For gas-giant cores that grow by accreting ice-rich pebbles, the ice will evaporate in warm regions of the giants’ atmospheres, saturating them with water vapor and forming “steamworlds”.

Wei Zhu et al 2017 ApJL 849 L31

MOA-2016-BLG-290, a lensing low-mass star or brown dwarf in the galactic bulge, is the first microlensing event for which we have signals from three well-separated locations: Spitzer, K2, and Earth.

New multiband photometry and optical spectra for a sample of spectroscopically confirmed supernovae will provide insight into Type II supernovae explosions and develop methods for their classification.

Vinyl cyanide, which can form cell membrane-like structures in liquid methane, has been spatially mapped in Titan’s atmosphere, appearing to be most abundant at altitudes above 200 km.

Icy minor planets are shown to typically retain some of their water through their host star’s evolution into a white dwarf, allowing them to potentially pollute the white dwarf’s atmosphere after a later collision.

Zheng Cai et al 2017 ApJL 849 L18

HST observations suggest that smaller galaxies are main sources of intergalactic C IV absorbers, and such small galaxies play a major role in the metal enrichment of the intergalactic medium at z ≥ 5.
