Very Large Telescope
6 reportsResearch connected with Very Large Telescope is followed through data pipelines, together with instrument configuration and observing campaigns. Judgments about instrument configuration are tied to raw and calibrated measurements and technical performance records rather than prominence or repetition; confidence is limited by the fact that weather, detector limits, and target selection can shape the available record.
Triple-Lobed Asteroid 44 Nysa Imaged With Orbiting Moon in Asteroid Belt
Astronomers have resolved asteroid 44 Nysa as the first known triple-lobed body in the main belt, using adaptive optics on major ground-based telescopes. The object also hosts a small moon, raising new questions about asteroid formation and evolution.
VLT Reveals Strongest Evidence Yet for Betelgeuse's Companion Star
Astronomers using the Very Large Telescope have obtained the clearest direct image to date of a faint companion star near Betelgeuse, advancing a century-long search for evidence that the red supergiant is part of a binary system
Hubble Reveals High-Speed Gas Bullets from Rare Helium Nova in Milky Way
Astronomers using Hubble and other observatories have observed V445 Puppis, the Milky Way's only known helium nova, ejecting dense gas clumps at speeds up to 32 million kilometers per hour
Possible Exomoon Candidate Challenges Definitions in Distant Star System
Astronomers using the Very Large Telescope have detected a moon-like object orbiting a brown dwarf in the CD-35 2722 system, raising questions about how to classify such bodies beyond our solar system
Giant Exosatellite Discovery Redefines Boundaries of Planetary Systems
Astronomers have identified a Jupiter-sized exosatellite orbiting a brown dwarf, itself in orbit around the star CD-35 2722. The finding, made using high-resolution spectroscopy, challenges current definitions of moons and planets.
Webb Telescope Detects Hidden Giant Planet in Beta Pictoris System
Astronomers have identified a third giant exoplanet in the Beta Pictoris system using the James Webb Space Telescope's spectroscopic capabilities, revealing a world previously concealed by the system's bright debris disk
