Finding a black hole isn't straightforward, and it's even harder the more distant such a behemoth is.

Because black holes absorb all flavors of light, telescopes typically can't see them directly.

But any black hole will leave fingerprints: for instance, its gravity will influence the movements of objects around it — and those objects, telescopes can study.

Now, chasing one such clue, astronomers have found a black hole in a cluster just outside the Milky Way, making it the first black hole ever spotted beyond our own galaxy with this technique.

The astronomers made the discovery using the European Southern Observatory's Very Large Telescope (VLT), which is perched atop a desert mountain in northern Chile.

The researchers turned the VLT's eyes upon NGC 1850, a cluster nestled in the neighboring Large Magellanic Cloud about 160,000 light-years away from Earth.

Here, scientists could look at thousands of stars in one go.

Artist’s animated view of the black hole in NGC 1850 distorting its companion star

This artist’s impression shows a compact black hole 11 times as massive as the Sun and its companion, a five-solar-mass star.

Although the star's movement is not displayed in this view of the binary, the star orbits the black hole.

The two objects are located in NGC 1850, a cluster of thousands of stars roughly 160 000 light-years away in the Large Magellanic Cloud, a Milky Way neighbour.

The distortion of the star’s shape is due to the strong gravitational force exerted by the black hole.

A journey to NGC 1850

NGC 1850, a cluster of thousands of stars roughly 160 000 light-years away in the Large Magellanic Cloud, a Milky Way neighbour.

Among many stars, this cluster is home to a black hole 11 times as massive as the Sun and to the five-solar-mass star orbiting it.

By looking at the star’s orbit, a team of astronomers were able to infer the presence of the black hole, making it the first small black hole outside of our galaxy to be found this way.

For this discovery, the team used the Multi Unit Spectroscopic Explorer (MUSE) instrument at ESO’s Very Large Telescope in Chile.
