**Cambridge, MA** – Astronomers have confirmed the existence of a supermassive black hole residing within the Large Magellanic Cloud (LMC), a dwarf galaxy neighboring our Milky Way. This discovery, detailed in a study published in the *Astrophysical Journal*, marks the closest supermassive black hole to Earth outside of our own galaxy’s Sagittarius A* (Sgr A*).
The research team, led by Harvard University doctoral student Jesse Han, traced the trajectories of nine hypervelocity stars – stars ejected from the LMC at incredibly high speeds. Their analysis, utilizing data from the European Space Agency’s Gaia space observatory, strongly suggests that these stars were flung out by the gravitational forces of a supermassive black hole at the LMC’s core.
This black hole, while significantly smaller than Sgr A*, still boasts a mass approximately 600,000 times that of our sun. While the existence of supermassive black holes at the centers of most galaxies is theorized, this represents the first direct evidence of one within the LMC. The previous closest known supermassive black hole outside the Milky Way was located in the Andromeda galaxy, some 2.5 million light-years away.
The LMC, visible to the naked eye from the southern hemisphere, is located roughly 160,000 light-years from Earth. This makes the newly discovered black hole the nearest such object to our planet besides Sgr A*, which sits at the center of our own Milky Way galaxy, a mere 26,000 light-years away.
The study’s co-author, Caltech astronomer Kareem El-Badry, notes that while the LMC’s mass and structure suggested the presence of a supermassive black hole, this discovery provides concrete evidence. He emphasizes that further research is needed to pinpoint the black hole’s exact location within the LMC. This exciting find significantly advances our understanding of galactic evolution and the prevalence of supermassive black holes throughout the universe.
