New observations have confirmed that the object HD 100546 b (top), which is up to 34 times as massive as Jupiter and orbits a youthful star some 320 light-years from Earth, is a still-forming planet. The recent images of the surroundings of HD 100546 (the star) have revealed what appears to be a second still-growing planet, dubbed HD 100546 c (bottom). It could weigh in at up to 1020 Jupiter masses. Credit: Gemini Observatory/AURA/Thayne Currie – NAOJ
