Something for #PortfolioDay... I mostly do space #SciArt. Here is my digital drawing of the Rosette Nebula, a large star-forming region which is about 5000 light-years away. 🔭

Work in progress. Few sessions done, more sessions to go. Painting of the Butterfly Nebula, a bipolar planetary nebula, acrylic on canvas 30x40cm
#painting #acrylics #SciArt #acryliconcanvas #ArtYear #Art #nebula
Mini canvas of a nebula painting next to larger blank black canvas. Black canvas with Butterfly nebula outlined with colored graphite First session of acrylic painting. Large portions of (blue, white, red, yellow) butterfly nebula are painted on black canvas. Second acrylic later of colours added to Butterfly nebula. Painting is slowly starting to have better shape and brighter colours.

Tomorrow Mercury becomes closest planet to Earth and remains closest until 31st July 2026. I drawn Solar System bodies in Procreate. Distances can be explored in my Streamlit App: solar-system-distances.streamlit.app ps. there will be days in 2027 when Mars is the closest planet to Earth #SciArt 🧪 🔭
Screenshot of Streamlit web application "Distances in Solar System". Seeing distances from Earth to the Moon, Venus, Mercury, Sun and Mars for 28th June, and then below it for 29th June when Mercury becomes closest planet to the Earth, and remains closest for the rest of this year. Solar System bodies are illustrated in Procreate. Streamlit App: https://solar-system-distances.streamlit.app

Not sure what I was expecting as an outcome, but here is a version of our Moon, it's a sort of topographic paper cutout digital drawing #SciArt #Astronomy #Moon #ArtYear 🐡 🔭
Topographic map of the Moon in a paper cutout style, made in Procreate. On image one can see a layers of squiggly surfaces overlayed on top of each other where colour varies from black to white, giving indication of depth. Drawing is based of topographic image of the Moon (data Lunar Orbiter Laser Altimeter, author M.A. Wieczorek, original topographic map source is Wikipedia).

10 months & 20 astronomy written & illustrated pages later, I completed my first publishing cycle. Written in Panonian Rusyn & illustrated in Procreate for "Заградка"; 10 monthly publications. Here are examples of my 2 favourite sketch-to-page comparisons. #SciArt #kidlitart #kidlit #Astronomy 🔭 🐡 🧪
Comparison of sketch-to-page of a Astronomy article. Showing constellations visible in September on the northern hemisphere, focusing on area around milky way. Written in Panonian Rusyn, illustrated in Procreate. Comparison of sketch-to-page of a Astronomy article. Showing face on and edge on Milky Way galaxy. Enhanced spiral structure and marked our location. Written in Panonian Rusyn, illustrated in Procreate.
