ESA's Gaia mission discovers the biggest stellar black hole in our galaxy yet

Gaia BH3 is 33 times the size of our sun and is relatively close to our planet.

The ESA team used data from ground-based telescopes like the European Southern Observatory to confirm the size of the newly discovered celestial body.
