Spectroscopic detection of molecular hydrogen frozen in interstellar ices.
TL;DR: A weak infrared absorption feature near 4141 wavenumbers (2.415 micrometers) in the spectrum of WL5, an infrared source in the rho Ophiuchus cloud complex, has been detected, attributed to molecular hydrogen created by irradiation and frozen in situ into water-rich ices.

TL;DR: Nova V2362 Cygni has undergone a number of very unusual changes as mentioned in this paper, including a rapid increase in the Swift X-ray telescope flux and a sudden shift in excitation of the visible and IR spectrum back to low levels.
The 8 micron band of silicon monoxide in the expanding cloud around VY Canis Majoris
TL;DR: In this article, the vibration-rotation transitions of silicon monoxide in VY CMa were observed to originate in accelerating, expanding, and cooling (600 K) layers of a circumstellar cloud at a distance of roughly 0.15 minutes from the central star.
The detection of HCN on Jupiter
TL;DR: In this paper, three R-branch lines of the nu-2 fundamental of HCN near 13.5 microns were observed in absorption, from which the HCN column density is inferred to be 0.005 cm-am with an uncertainty of a factor of two.

TL;DR: In this article, velocity-resolved spectra of the H2 1-0 S(1) (λ = 2.1218 μm) emission line were obtained in four regions within the central 10 pc of the Galaxy where the supernova-like remnant Sgr A East is colliding with molecular clouds.
