Hubble reveals dusty debris from two rare cosmic collisions near Fomalhaut, debunking a long-held planet mystery.
NASA’s Hubble Space Telescope captured rare images of dusty debris from two massive cosmic collisions near the star Fomalhaut, 25 light years away, resolving a decades-old mystery.
A bright spot once thought to be a planet was revealed to be transient dust from collisions between space rocks at least 60 kilometers wide.
The events, occurring within 20 years, are extremely rare—possibly once every 100,000 years in such regions—making this double occurrence surprising.
The debris temporarily mimicked planets but is now dispersing.
Scientists say the findings offer a real-time look at planetary formation, likened to a “toddler picture” of our solar system.
The study, published in Science, highlights how such violent events shape planetary systems and underscores Hubble’s ongoing role in uncovering dynamic cosmic processes.
