Discovery of Beta Pictoris d
Astronomers announced on July 15, 2026 the detection of a faint, cold gas giant orbiting the 20-million-year-old star Beta Pictoris, located 63 light-years from Earth in the southern constellation Pictor. Two independent teams identified the planet—referred to as Beta Pictoris d—in data collected a few days apart late in 2025. A Scottish-German collaboration used the European Southern Observatory’s Very Large Telescope in Chile, while a California-led group employed NASA’s James Webb Space Telescope. Both groups reported the findings in *Astrophysical Journal Letters*. The planet is roughly Jupiter-sized, 100 times fainter than its star, and completes an orbit in about 91 years, slightly longer than Uranus’ period around the Sun.
Context: Beta Pictoris System and Imaging Challenges
Beta Pictoris already hosts two brighter, directly imaged planets. The star’s brilliance and the presence of these companions had masked the new, dimmer world in archival data for more than a decade. Direct imaging of exoplanets remains rare; fewer than 100 of the roughly 6,000 confirmed exoplanets have been captured this way, most through transit methods that detect dimming of starlight.
Official Scientific Commentary
Researchers emphasized the planet’s significance for understanding early planetary system evolution. The discovery provides a clearer view of a system still stabilizing after the formation of its giant planets, offering a laboratory for studying how smaller, terrestrial worlds may continue to coalesce.

- “It was very much playing hide-and-seek for 11 years,” — Markus Bonse, co-leader, European Southern Observatory
- “The giant planets have formed, but smaller terrestrial planets could still be forming,” — Aidan Gibbs, University of California San Diego
- “is probably our best look at a planetary system just after it has formed and is still in the process of stabilizing” — Aidan Gibbs, email
- “and we are very excited to see what more can be learned about it.” — Ben Sutlieff, University of Edinburgh
Implications for Planet Formation Studies
Beta Pictoris d represents the dimmest planet ever directly imaged from Earth, expanding the observable range of young, faint exoplanets. Its detection demonstrates the complementary power of ground-based and space-based telescopes and suggests that additional, low-luminosity worlds may be uncovered in existing data sets, refining models of planetary system maturation.
