Vera Rubin was an American astronomer whose pioneering work on galaxy rotation rates provided the first evidence for the existence of dark matter.

This seminal breakthrough led to the creation of a whole new field of astronomy, as her once-startling theory became an accepted part of the still-evolving story of the universe.

Favored to win the Nobel Prize for years, she died in 2016 without ever receiving a call from Stockholm.

Also looks like someone at the UK's Royal Astronomical Society set up a Mastodon account and is crafting custom posts for it, but it only has ~300 followers compared with their >50K on Twitter:

I see this all too often -- major public/nonprofit organizations set up shop here, but don't know how to best cross-link/promote it, so the accounts get kind of lost. If you care about #astronomy & like their work, give them a boost or follow ๐Ÿ˜€

#JWST reaches new milestone in quest for distant #galaxies.

The light from these galaxies has taken more than 13.4 billion years to reach us implying they existed 400 million years after the big bang, when the #universe was only 2% of its current age.

These galaxies are extremely faint because of their great distance from us. Astronomers can now explore their properties, thanks to JWST's exquisite sensitivity.

NASA's Webb reaches new milestone in quest for distant galaxies

An international team of astronomers has used data from NASA's James Webb Space Telescope to report the discovery of the earliest galaxies confirmed to date. The light from these galaxies has taken more than 13.

No-one would ever get the two terms mixed-up if they were called:

Astronerdical

and

I have rediscovered Celestia ๐ŸŒ  (https://celestia.space/), the absolutely mindboggling #astronomy simulation for #linux and game consoles (aka. windowsยฎ). For more than a decade it has been removed from #debian but after a todays mention (and in fact I had to figure out its forgotten name) I realised that they again offer fresh working versions for download. ๐Ÿคฉ
And I am speeding through the galaxy arm right now at about 500 ly/s. ๐Ÿ˜ (That's about 10^10 c.)

Celestia is a free space simulator for Windows, Linux, macOS, iOS and Android. You can freely explore space in three dimensions. The program displays objects and orbits based on scientific data.
