Beautiful bow shock nebula. I did not know that Cataclysmic variable stars could produce bow shocks. This one was also discovered with the help of amateur astronomers. #amateurastronomy 🔭 I updated the wikipedia article about bow shocks: en.wikipedia.org/wiki/Bow_shock

It’s a brown dwarf! It’s not a mystery! It’s still an exciting distant brown dwarf, so I wouldn’t call it mundane.

Researchers use JWST looking for “exomoons” around brown dwarf In this blog post I look at two works using JWST to search for exomoons around nearby brown dwarfs.

A new video we made, which focuses on one of my favourite objects in the night sky, Caldwell 4, aka NGC 7023, aka The Iris Nebula. It has quite a story to tell, which relates to why the sky is blue, and why some other things are red! 🔭🧪 youtu.be/aNJgQlJDPMY

W0503-5648, is a "cold" brown dwarf (Y-dwarf). #Hubble image 🔭📷 It is about 10 parsec (33 lightyears) distant and has a temperature of around 94°C (201°F) and was discovered by volunteers of the backyard worlds project. #citsci program: archive.stsci.edu/proposal_sea...

Sulphur tuft (Hypholoma fasciculare) is a mushroom that glows under ultraviolet-light. #Fluorescence 💚 Left is without UV-light and right is with UV-light. #mushrooms 🍄

I did also see a mushroom that I think is fluorescent. It should not be too far, so after lunch I could go outside again with my UV-flashlight and try to take a picture.

I was going for a small hike and did take some pictures of #mushrooms. 🍄 Many different shapes and colours to explore.

ESO 583-4, which was observed with #Hubble because of a past tidal disruption event (TDE), called AT2022dsb. A TDE is when a the black hole in the center eats a star. ⭐+⚫➡️💥 The survey also has a funny name: GHOSTBUSTERS 👻🚫 filters: F338W+F615W #BlackHole program: archive.stsci.edu/proposal_sea...

A well-studied cold brown dwarf: WISE 1828+2650 with #JWST NIRCam (in the circle I did draw). It is well-studied, but even with JWST it is still holding some secrets. Some results suggest it is a binary, other works find it to be single. #BrownDwarf

Interesting work by Andrew Householder+. They use 8 hours of #JWST/MIRI LRS to search for satellites around the nearby brown dwarf binary Luhman 16 with the transit method. They don't find any, but are sensitive to objects as small as our Moon. iopscience.iop.org/article/10.3...

I've read about ZTF SLRN-2020 event where a star basically ate it's own planet. So I decided to try and depict this from a planet's perspective. It's atmosphere evaporating and getting ripped away by the star. #SciArt #spaceart #astronomy

Because of scraping accounts I started to add my name to my images/animations. I started on reddit to post images and there someone did steal one of my images and posted it on another subreddit without giving credit. They got 1.2k upvotes, while my original sat at 169 upvotes.

Starting to see nice separation of the dust and ion tails now. This is C/2025 A6 Lemmon from Oct 21. 60 minutes of data. Much better than where I started this week at 11 minutes. Captured with #Nikon D5300a and William Optics z73 430mm scope. #astrophotography #comet #nightsky

I used to hate drawing trees and foliage, but I think I'm getting better. I have this autumn maple in front of my kitchen window. So it inspired me to start a small pixel series. Here's episode 1. #pixelart

The crackdown on LGBTI people in Turkey is drastically intensifying. New draft laws criminalise anyone who “engages in behaviours contrary to biological sex and general morality.” Even promoting or supporting LGBTI rights could become a crime. 🧵

I was wondering what kind of #bird I did get in front of my lens. Turns out to be a European dipper (Cinclus cinclus). It was sometimes diving. Probably for aquatic insects. Great experience. (image licence: CC BY-NC 4.0)

I finally did create a clean 3D model of the Cassiopeia A light echo. A lot of simplification, but I am satisfied with the result.
