Hydrogen Gas on collision course with Milky Way galaxy

Posted by on Friday, January 29, 2016

An invisible cloud of hydrogen gas is on a collision course with our Milky Way galaxy, the cloud known as the Smith Cloud, is plummeting toward us at nearly 1 million km/h.

Like a boomerang, the cloud was launched from our galaxy around 70 million years ago and is on a return collision course in about 30 million years.

This collision is expected to ignite a spectacular burst of star formation, maybe even enough gas to make 2 million suns.
