For Day 2 of #SpacetoberChallenge #Spacetober prompt Moon, I'm posting an acrylic painting I did a few years ago for my friend @aurora_kess #SpacetoberChallenge_04 #SciArt

Mixed media Witch Head Nebula. The Witch Head Nebula, also known as IC 2118, is a reflection nebula located about 900 light-years away in the constellation Eridanus. 🐡🔭 #Sciart #spaceart #witch 1/4

The blue color of the nebula is due to interstellar dust reflecting Rigel's light, which is more efficiently scattered by blue wavelengths. I used hot glue and cotton wool to create a 3D effect - adding texture and depth to the artwork. 3/4

The cotton wool gives the piece a soft look, similar to the nebula's cloud-like appearance, while the hot glue creates and highlights sharp details, enhancing the nebula's "witch-like" profile. 4/4

I really enjoy watching videos of acrylic pours and it was very fun to incorporate the technique for this series: 1. Impressions of a gas giant 2. Impressions of an exo-moon 3. Impressions of Mercury 4. Impressions of Mars. #spaceart #planet #acrylicpouring #astronomy

Blue represents data from the Atacama Large Millimeter/submillimeter Array (ALMA), highlighting cold molecular gas. This dataset (Kaufman+16) allowed astronomers to trace the motion of the gas, revealing where the encounter has compressed gas and triggered new star formation! 4/7

Calculations suggest IC 2163 is currently moving past NGC 2207, having made its closest approach ~ 40 million years ago. However, IC 2163 lacks the energy to escape NGC 2207's gravitational pull. Eventually, in billions of years, they will merge into a single massive galaxy. 7/7

Friends in the NL, are you looking for something to do on Saturday? I'll have a table at the Home Made Market in den Haag where l'll be selling my space- themed postcards, stickers, bags, and original acrylic paintings. homemademarket.co.nl/eveneme…

This is my digital art of NGC 1360, the robin's egg nebula, inspired by the Astronomy Picture of the Day Aug 5, 2023: apod.nasa.gov/apod/ap230805.… 🔭 #procreate #digitalart #spaceart 1/3
Digital art: black background and a turquoise egg shaped nebula with pink in the centre and some dark cloudy dust lanes across it. A few stars spattered across the image.

The object lies ~1,500 light-years away in the constellation Fornax. The nebula looks similar to a robin's egg and spans about 3 light-years across. #procreate #digitalart #spaceart 2/3

It is a planetary nebula, formed by final phase in the evolution of an aging star, or in this case, maybe two stars -- visible at the center of the nebula, is a binary system likely consisting of two evolved white dwarf stars.  3/3
