Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space.
Three stellar black holes found in our galaxy, Gaia BH1, Cygnus X-1 and Gaia BH3, have masses that are 10, 21 and 33 times that of the sun, respectively.
The researchers used the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert and other ground-based observatories to confirm the mass of Gaia BH3, and their study has also offered new clues to how such huge black holes came to be. The findings appeared Tuesday in the journal
Scientists believe stellar black holes with masses such as Gaia BH3’s formed when metal-poor stars collapsed. These stars, which include hydrogen and helium as their heaviest elements, are thought to lose less mass over their lifetimes, so they have more material at the end that can result in a high-mass black hole.
Now, the team hopes the research can allow other astronomers to study the colossal black hole and uncover more of its secrets without having to wait for the rest of the Gaia data release, slated for late 2025.
