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.

https://www.nasa.gov/mission_pages/chandra/news/black-hole-image-makes-history



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.

I wasn't as close for this one, but I did manage to catch a couple of decent pictures:

Saw this on gfycat when I went to upload my sims videos for today's update... thought it was particularly cool in a "WE LIVE IN THE FUTURE, BITCH" kinda way.

The difference 50 years makes:


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.

Found Everyday Astronaut's channel over the weekend. Here's a collection of not going to space today.

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.
