APOD: 2026 February 8 – Active Sunspot Region 4366 Crosses the Sun
A different astronomy and space science related image is featured each day, along with a brief explanation.apod.nasa.gov
Enter the Dragon 🐉🥋
Here it is – my new JWST image of the young protostellar outflow system in Cassiopeia called HH288, aka The Dragon Jet.
We discovered it in the 1990s & the NASA/ESA/CSA JWST reveals stunning new detail, including several new jets crossing the main dragon 🙂👍
This is a 4K version – you can view & download the full 12K image here: flickr.com/gp/markmccaughrean/…

Finally some good news.
You may have been aware of the green hydrogen & ammonia production facility, INNA, proposed for construction on the Chilean coast, very close to Paranal & Armazones, home to ESO's VLT, VLTI, VISTA, & ELT telescopes.
It posed an existential light & atmospheric pollution threat to those world-leading astronomical facilities.
Fortunately, the concerns of the scientific community have been heard & the project cancelled.

Hello Universe!
Moved to new server.
Re-introduction - Been on here since 2022 and should write an intro again. I'm deaf, I'm a fan of open-source projects, so this will be short and sweet.
Post random ramblings, news, techie stuff, boost mostly cat pics. I just like computers and hang around here.

![XKCD comic #3196 "Aurora Coolness" https://xkcd.com/3196/
explanation from ExplainXCKD wiki https://www.explainxkcd.com/wiki/index.php/3196:_Aurora_Coolness
transcript:
A graph of “aurora coolness” over many hours. The coolness starts at “visible glow on the horizon, color only visible in photos” and gradually moves up and down to “spectacular ribbons of color spanning the sky and illuminating the landscape”, which is is labeled “5 or 10 minutes”, then gradually goes back down, almost getting all the way up, and eventually ending back at “visible glow on the horizon, color only visible in photos”.
Title text: I've had countless nights where the line never left the bottom zone of the graph, but the few moments where it's climbed all the way to the top have made up for them all.
explanation (truncated to fit alt-text):
The graph in this comic reports events during an aurora rated on 'coolness' over time, and shows that truly interesting events are fairly frequent, but often short-lived and not predictable. Both the caption and the title text encourage the viewer of an aurora to be patient with the 'boring' stuff, as more exciting events could happen with little or no notice. The caption gives general advice, while the title text reports Randall's own experiences.
The comic was published at around the time when low-latitude auroras were particularly anticipated to be visible, and may even have been displaying themselves to Randall in the immediate run-up to publication[...]](https://friendica.hellquist.eu/photo/preview/640/5398260 "XKCD comic #3196 \"Aurora Coolness\" https://xkcd.com/3196/
