second black hole found at the centre of our galaxymark peplow seven stars
orbiting the region identify the invisible object.

a second black hole lurks at the centre of our galaxy, according to astronomers
who have watched a cluster of stars spinning around it.

just three years ago, astronomers confirmed that the milky way revolves around a
supermassive black hole1, called sagittarius a*, which is about 2.6 million
times more massive than the sun.

but now a much smaller black hole, just 1,300 times our sun's mass, has been
found orbiting about three light years away from its supermassive cousin.

jean-pierre maillard, an astronomer from the institute of astrophysics in paris,
france, led a team that looked at a very bright area of the galactic core called
irs 13, previously thought by astronomers to be a single object.
