Two massive space rock collisions detected around Fomalhaut
Hubble Space Telescope observations have identified two transient debris clouds produced by separate planetesimal collisions in the Fomalhaut planetary system, located about 25 light-years from Earth, with the second event detected in 2023. The findings indicate that objects previously interpreted as candidate exoplanets are instead the dusty aftermath of rare, high-energy impacts within the system’s debris belt.
