There are hundreds of high-velocity gas clouds moving at hundreds of km/s through the outskirts of our galaxy, mostly in stable orbits that keep them out of the galactic plane. They're typically irregularly shaped, thousands of light years across, and contain many millions of times the mass of our Sun. However, one such cloud, known as the "Smith Cloud" (above), is very different from all the others. It's much more distant, and it's moving towards us incredibly rapidly: at about 310 km/s, or around 700,000 miles per hour. And when I say it's moving towards us, it's projected to collide at extreme velocities with the disk of our galaxy in about 30 million years: a long time for a human, but a very short time for our galaxy. (For comparison, it takes our Sun about 200 million years to complete a single orbit around our galactic center.) Here's how we found this out.

Let's keep this discussion on sober, mature grounds.

“it’s projected to collide at extreme velocities with the disk of our galaxy in about 30 million years:”
30 Million years?

He who smelt it, dealt it. He who denied it supplied it.

Well MrD has been quite active lately but I don't think he is to blame for this.

“Our sun will go nova in about 49 billion years.”
“Oh, my god! What are we going to do? What do I tell the kids?”
“Relax, man, 49 billion years is a long time.”
“Forty-nine billion? Whew. I thought you say 49 MILLION!’

I’m sure that before the 30 Million years are up, the EPA will have outlawed the Smith Cloud.....
