Black Holes Discovered Close to Earth

Discovery: Gaia spacecraft has found a giant black hole named Gaia BH3, approximately 2,000 light years away.
How it works: Stars orbiting a black hole appear in empty space, but their light shifts due to the Doppler effect, revealing the black hole’s presence.
Key Findings:
Black holes in the Milky Way are often invisible but detectable through X-ray emissions. The Gaia BH3 is much larger than previous discoveries, including those in the Magellanic Cloud.
Next Steps: This discovery will help further understand cosmic objects and black hole formation.
