Milky Way's black hole to eat planet-forming cloud

A young star and its planet-forming cloud are being pulled towards the huge black hole at the centre of our galaxy, astronomers say.
Earlier this year, researchers reported seeing a cloud of ionised gas and dust falling in towards SgrA*.
They suggested that it formed when gas streaming from two nearby stars collided, like wind-blown sand gathering into a dune.

Planets Can Form in the Galactic Center

At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. Stars crowd each other as they whiz through space like cars on a rush-hour freeway.

Yet new research by astronomers at the Harvard-Smithsonian Centre for Astrophysics shows that planets still can form in this cosmic maelstrom. For proof, they point to the recent discovery of a cloud of hydrogen and helium plunging toward the galactic center. They argue that this cloud represents the shredded remains of a planet-forming disk orbiting an unseen star.
