Over 29 days last spring, NASA's Mars Exploration Rover Opportunity documented this 360-degree panorama from multiple images taken at what would become its final resting spot in Perseverance Valley. (NASA)

Black hole pictures.

Event Horizon Telescope team:
• Black hole pictured weighs 6.5 billion times more than the sun
• Material moving around the black hole accelerated to light speeds



The black hole lies about 55 million light-years from Earth. Countless black holes are now thought to exist in the universe, including an estimated 100 million in our galaxy alone. Astronomers say none are near enough to Earth to pose a threat.

It's amazing to me how similar they look, actually.

IMO I think people don't appreciate just how MUCH MORE data is in the second photo. Like, think of the old quote:
Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.
Computer Networks, 3rd ed., p. 83. (paraphrasing Dr. Warren Jackson, Director, University of Toronto Computing Services (UTCS) circa 1985)

That's in 1985. The article here updates it for SD cards: https://what-if.xkcd.com/31/

The amount of data in the second photo would be BUILDINGS full of documents like the photo on the left.

There is a barge landing planned for the rocket. It looks like the barge is on the northern side of the landing area -- almost due east from Charleston South Carolina.

Good launch. Good first stage recovery. Good initial orbit. Next will be an additional second stage burn and satellites deployment in about half an hour from now.

Second burn was blink-and-you'll-miss-it. Only 3 seconds. Satellites deployment successful.

It was a nice looking launch. I got super busy this evening and didn't quite have enough time to get set to get a picture. The neat thing was that I was able to coordinate with my cousin in Charleston so that she was able to see the landing burn.
