How has cosmology changed from 2000 to 2025? At the turn of the century, we had evidence for a dark energy and dark matter dominated Universe, as the Standard Model of cosmology came into focus. 25 years later, it's starting to crack. bigthink.com/starts-with-... #physics #space #astro #science

Will the Sun make a planetary nebula when it dies? Nearly every planetary nebula we prominently see is from a high-mass star in a multi-star system. So will the Sun make one? Almost certainly. Here's why. bigthink.com/starts-with-... #space #astronomy #astro #physics #science

Why are maps of the cosmos always oval-shaped? #AskEthan When astronomers show us maps of the Universe, they show the entire sky mapped onto an ellipsoid. Here's why, how, and what it sacrifices. bigthink.com/starts-with-... #space #astro #science #cartography

Hello Fediverse, time for an introduction! My name is Matthew (or Matt, Mattie), and I'm a non-binary software engineer based in the UK. I've been on fedi before but I've decided to make a presence here where I can share my more professional stuff. I'll be posting about: 

- Typescript, React, Astro and Webdev
- Unreal Engine, C++ and game dev
- Devops and Linux, primarily Opensuse

Feel free to follow me!

JWST has captured Neptune’s auroras for the first time! The most distant planet from the Sun has a magnetic field tilted at a strange 47-degree angle, causing auroras away from its poles. Webb also found Neptune’s upper atmosphere has cooled by hundreds of degrees—likely why its auroras remained undetected for so long.

EDIT - The answer is that it is Falcon 9. And the spiral is excess fuel released from the rocket.
#astro #question This object was just passing over Brno (21:00-21:03 CET) from NWW to SEE. It started as a small butterfly from light - I thought about some kind of halo around a bright star. But it was moving in satellite speed, and the halo was rotating and growing. Photos are bad because it is from phone.

JWST observed Herbig-Haro 49/50, a protostellar outflow where a still-developing star’s jet collides with surrounding gas, shaping intricate structures. A distant spiral galaxy, seen by chance, aligns in the background.
