Huge gas cloud headed for Milky Way

Smith’s Cloud – a massive cloud of gas orbiting the Milky Way galaxy – contains enough gas to make 2 million stars the size of our sun. It’s moving through space at 700,000 miles (1.13 million km) per hour on a collision course with the Milky Way. In about 30 million years, it will crash into our galaxy, causing a brilliant burst of star formation.
