The Multi-Object Optical and Near-infrared Spectrograph (MOONS) at the Very Large Telescope in Cerro Paranal, Chile, made its first observations, the European Southern Observatory announced on September 3, 2026.[^1]

The detection was conducted using the GRAVITY+ instrument at the same observatory in the Atacama Desert.[^2] Two independent teams reported the detection of oxygen in the galaxy JADES-GS-z14-0 using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and the James Webb Space Telescope (Webb) in studies publicized in March 2025.[^5]

In a paper submitted to arXiv on September 4, 2026, Antonin Wargnier and co-authors stated that the Near InfraRed Spectrometer (NIRS3) onboard the Hayabusa2 spacecraft observed asteroid (162173) Ryugu, searching for signatures of water-bearing minerals.[^3] A separate paper submitted to arXiv on September 4, 2026 and accepted for publication in Astronomy & Astrophysics, by Tom Briand and colleagues, extended a 1D thermochemical and diffusion model to a pseudo-2D version with latitudinal variations to infer deep oxygen (O/H) and carbon-to-oxygen (C/O) ratios on Uranus and Neptune from observed upper-tropospheric carbon monoxide (CO).[^4]
