Non-space space news 

Looks like some of the paper airplanes I made as a kid. They didn't have sonic booms either

Andrew McCarthy takes great space photos:

That's some nice regolith.

Good article explaining the Radcliffe Wave, which shows a massive object, most likely dark matter, has collided with the Milky Way:

Guess this is a pretty big deal. Thanks for the post.

A large team of space scientists working in Canada has found evidence of a fast radio burst with a steady 16-day cycle. The team has published a paper describing their findings on the arXiv preprint server.

The repeating pattern suggests the source could be a celestial body of some kind orbiting around a star or another body. In such a scenario, the signals would cease when they are obstructed by the other body. But that still does not explain how a celestial body could be sending out such signals on a regular basis. Another possibility is that stellar winds might be alternately boosting or blocking signals from a body behind them. Or it could be that the source is a celestial body that is rotating.

Shit I'd hate to get hit by one of those things.

The biggest cosmic explosion on record has been detected – an event so powerful that it punched a dent the size of 15 Milky Ways in the surrounding space.

The eruption is thought to have originated at a supermassive black hole in the Ophiuchus galaxy cluster, which is about 390m light years from Earth.

"the event is thought to have taken place several hundred million years ago, with the black hole showing no signs of dramatic activity at present."

How would they know what is going on at the present time?

The next Mars Rover has been named Perseverance, and will launch on July 17, 2020:

Supermassive black holes, while giant cleansers of everything, also create huge amounts of water and organic compounds. When black holes collide or galaxies merge, their mass increases and stars stop forming as the black hole emits "active galactic nuclei" and the subsequent xray emission interact with the outer gases in the outer part of the galaxy  and start the process of creating water and tholin, which is a precursor to life when oxygen is added.

We might have all come from a black hole colliding with another black hole.

Also interesting and on topic: The last time our own galaxy had an active galactic nuclei event was a little over 3 million years ago, right before the first precursors of humans began to show up on Earth.
