The #MinorPlanetCenter is the globally accepted authority on handling observations 🔭 and reports of new #asteroids ☄️, comets, and other small bodies 🚗 in the #SolarSystem : discovery of an unusual asteroid, 240,000 km from Earth https://www.astronomy.com/science/astronomers-just-deleted-an-asteroid-because-it-turned-out-to-be-elon-musks-tesla-roadster
I've had a lot of people ask how BlueSky compares to Mastodon and the Fediverse. I've tried to make the answer as simple and easy to understand as possible:
🦋 BlueSky is designed to give corporations and wealthy people full control of the network. All of its traffic has to flow through expensive-to-run corporate relays.
The Fediverse is designed to give ordinary people control of the network. All of its traffic flows directly from one cheap-to-run server to another.
Type Ia supernovae are vital for measuring the expansion of the Universe. So far, a few thousand have been found and led to the discovery of dark energy. The upcoming Vera Rubin Observatory will shatter those numbers, finding millions of exploding stars and allowing astronomers to map out the expansion of the Universe in unprecedented detail. If all goes well, its survey will begin in just a few months, scanning the entire southern sky every few nights.
On this day in 2001 Wikipedia started.
Things I regret: Looking at github issues for the open-source self-driving car conversion kit.
Thousands of people use these things on public roads.
A marvelous ant in Micrographia.(1665) The ant gave Robert Hooke a lot of trouble since she wouldn't quit moving around as he tried to draw her. He ended up dipping her in brandy, ... though he does say that she woke back up and ran away. Gotta love this girl for surviving and escaping!
He supposes that the ant was drunk... But it probably was simply deprived of O2. I've seen ants who fell into water revive in a similar way when their spiracles (pores) dry off and they can breathe again. #ants
I’m not sure who made this t-shirt but I think I need to have it.

And here is a listing of sky events in the *Southern* hemisphere in 2025: https://astroblogger.blogspot.com/2025/01/coming-events-year-of-southern.html
What the article doesn't mention is that #MichaelJFox and his foundation have raised over $2B for #Parkinson's research, MORE than ALL government investment in a cure.

The carbon in your body formed through fusion in the hearts of stars and was then thrown out into the cosmos to seed stellar nebulae with the elements for life. Now, researchers are discovering just how long a journey that carbon has gone on, possibly circling the galaxy a few times before returning to our spot in the cosmos. They tracked giant conveyor belts that surround galaxies, pushing material out into space and then drawing it back into the galactic interior.
