Citizen Scientists Discover Hypervelocity Object Exiting Milky Way

NASA's Backyard Worlds project reveals a mysterious celestial body traveling at 1 million miles per hour, challenging astronomers to uncover its origins.

CWISE J1249, an object identified by citizen scientists, is moving fast enough to leave the Milky Way.
The object may be a low-mass star or brown dwarf, with a composition suggesting an ancient origin.
Theories about its high speed include interactions with supernovae or black holes.
Backyard Worlds: Planet 9 has enabled over 4,000 discoveries, highlighting the value of citizen science.
Further observations and analysis are underway to determine the object's exact nature and history.
