A Huge Gas Cloud Will Strike The Milky Way At 700,000 MPH

A huge gas cloud known as the Smith Cloud is on collision course with the Milky Way. If the cloud were visible, it would be 30 times larger than the Moon.

A huge gas cloud known as the Smith Cloud is on collision course with the Milky Way. The cloud, which is approaching at a speed of 700,000 miles per hour, is expected to hit the Milky Way at an angle of around 45 degrees, in 30 million years. As per the news release, the Smith Cloud if visible, would have an apparent size of about 30 times the diameter of the moon from tip to tail.

Discovered in the year 1963, the Smith Cloud measures 11,000 light-years long and 2500 light-years wide. Astronomers believe that when the cloud collides with our galaxy, it could produce a massive burst of huge new stars.

For years, astronomers have not been able to determine the composition of this giant gas cloud, which would hold clues for its origin. But now it has been confirmed that the cloud contains elements similar to our sun, which means the cloud came from the Milky Way’s outer edges and not from intergalactic space.

“We have found several massive gas clouds in the Milky Way halo that may serve as future fuel for star formation in its disk, but, for most of them, their origins remain a mystery,” said Nicolas Lehner, who is an astrophysicist at University of Notre Dame. “The Smith Cloud is certainly one of the best examples that shows that recycled gas is an important mechanism in the evolution of galaxies.”

Similar to our Milky Way’s outer disk, the Smith Cloud is rich in sulfur. Astronomers believe the Smith Cloud, has enough gas to generate two million suns when it strikes the Milky Way disk.

The findings were published in the Astrophysical Journal Letters.


  1. The universe is so incomprehensibly vast and despite all evidence people still believe the Genesis account. Most Jewish scholars accept the astronomy science and measure the Genesis account not as the beginning of the universe but the beginning of the Hebrew people’s experience in God’s world. Events such as you describe also indicate that creation is an ongoing(perhaps never ending) matter not a mere event as characterized in Genesis.
