Thanks to Sharmila Kuthunur for her @spacedotcom story today on the new U.S. federal administration's efforts to erase the contributions of people like Vera #Rubin from the #history of #astronomy.

Scientists alarmed as Rubin Observatory changes biography of astronomer Vera Rubin amid Trump's push to end DEI efforts
"The idea that they can somehow obliterate these sources is dead wrong — scientists in general and astronomers in particular are not going to take these threats lying down."Sharmila Kuthunur (Space)
Scientists with #ESAEuclid have discovered an Einstein Ring gravitational lens in a nearby NGC galaxies - something very rare, unexpected, and beautiful. NGC 6505 bends space, turning the image of a background galaxy into a ring.

(Asteroid YR4's) "...would, more likely, produce a meteor air burst rather than an impact crater due to its stony composition. It could cause damage as far as 50 km (30 mi) from the impact site."
Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032
More data will likely reduce the chance of an impact to zero. If not, we have options.Stephen Clark (Ars Technica)

Anticrepuscular Rays: A Rainbow Fan over Spain
A rare sight captured in Lekeitio, Spain, shows a rainbow with anticrepuscular rays converging opposite the sunset. This optical illusion occurs as sunlight reflects off rain and is partially blocked by clouds, creating a serene and surreal scene.

Here's the shot of the Rosette Nebula (Caldwell 49) I got last night. Red Cat 51 and ASI2600MC using Askar Colormagic C1+C2 filters.
Pulled out H, OIII, and SII channels out of the two image stacks and mapped them to the HOS palette, which I thought looked stunning. This is one of my favorite nebulae 😍
These filters are cool AF. Even straight out of the camera the images looked really pretty. I'm very happy with them.
Vera Rubin Was a Pioneering Female Astronomer. Her Federal Bio Now Doesn’t Mention Efforts to Diversify Science.

The edits to the webpage offer a glimpse into how far the Trump administration will go in refusing to acknowledge today’s inequalities as it purges federal initiatives promoting diversity, equity and inclusion.
This may be the strangest planet yet discovered. It seems to be a Pluto-size world circling the remains of three dead stars: two white dwarfs & a pulsar, as massive as the Sun but no bigger than Brooklyn.
If confirmed, it would also be the smallest exoplanet known.

Have We Discovered The Smallest Extra-solar Planet? - Astrobiology
Using pulsar timing techniques a team of researchers has discovered a trace of what may well be the smallest extra-solar planet ever discovered in the system of pulsar PSR J0337+1715.Keith Cowing (Astrobiology)
Fact: you can see quite a few planets in the night sky from Western Europe at the moment.
Bullshit: there is a super rare alignment of all the planets of the solar system, and they form a single straight line on the 25th January 2025
A reminder that humans are capable of great acts of wonder when we work together & embrace knowledge.
An international team of astronomers has discovered swarms of cold comets circling 74 nearby stars -- and got clear pictures of these "exocomet belts."

Astrophysicists reveal structure of 74 exocomet belts orbiting nearby stars in landmark survey
The Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have collaborated in the research that reveals the structure of 74 exocomet belts, it means, belts with minor bodies outside our solar system, around stars close to …Instituto de Astrofísica de Canarias • IAC
I've added a tip jar link to my profile page. The idea here is that once I get 100 euros in tips, I will be able to print a revised and improved prototype of the Acrux board game.
This is the first time that I've tried anything like this so please tell me if it works for you.

British mathematician and astronomer John Couch Adams died #OTD in 1892.
His most famous achievement was predicting the existence and position of Neptune, using only mathematics. The calculations were made to explain discrepancies with Uranus's orbit and the laws of Kepler and Newton.

I finished up processing everything (good) I got from the Mars occultation.
I did end up setting my scope up last night to get pics of the occultation. It was cold af, but I got some good data. I'll have more to share when I have time to do some processing, but I made up something quick this morning to share.
I finished up processing what I got from the Mars occultation on Monday night.
Here's a timelapse of Mars disappearing.
