Overview
- Two independent teams — one using ESO’s Very Large Telescope and one using NASA’s James Webb Space Telescope — detected the same faint source late in 2025 and published coordinated results in The Astrophysical Journal Letters on Wednesday, July 15, 2026.
- Analysis of roughly 11 years of archival VLT and JWST images showed the source persisted and moved consistently with an orbiting object rather than a background star, and the teams deliberately kept their work separate to avoid bias.
- Researchers characterize Beta Pictoris d as a young gas giant about 2.4 times the mass of Jupiter on a roughly 91‑year orbit around the 63‑light‑year‑distant star Beta Pictoris, with temperature and spectral data supplied by Webb’s NIRSpec observations.
- The initial VLT signal survived advanced image cleaning, including machine‑learning techniques, while Webb’s integral‑field spectroscopy provided rapid spectral confirmation that the detection is a planet and not an instrumental artifact or disk feature.
- The planet helps explain structures seen in Beta Pictoris’s debris disk, makes the system only the second with more than two directly imaged planets, and points to archival mining and upcoming Extremely Large Telescopes as paths to find many more faint planets.
