I was a volunteer of astronomical research. Sometimes I edit wikipedia articles and I create images with #JWST data. German 🇩🇪 no genAI 🚫🤖 trans, chronic pain, mental illness https://melinathevenot.carrd.co/ she/her

That's no moon. It's a...hang on, what should we call it? 🤔 Our VLT has revealed evidence for a moon-like object in the CD-35 2722 system. Yet this new ‘exomoon’ detection is challenging cosmic labels! 🔭 🧪 #exoplanets 1/4

Another visualisation of JWST🔭 data from "Mab area", in the vicinity of the supernova remnant Cassiopeia A. Here we see older light from 2024 summer in red, newer light reaching us on Dec 2024 as green, and Jul 2025 as blue. Credits: NASA, ESA, CSA, STScI.

A false-color James Webb Space Telescope image of light echoes surrounding the supernova remnant Cassiopeia A. Broad, translucent ribbons of dust sweep diagonally from the upper left to the lower right, displaying a vivid rainbow of colors. Unlike a natural-color image, the colors encode time: red marks light that reached the telescope earlier, while green and blue indicate progressively later-arriving light. This creates layered bands that trace the outward motion of the supernova's light pulse as it illuminates interstellar dust at different distances.

Here I am following @melina-iras07572.bsky.social , tracking the light echo by time. The first 4 frames were captured a few weeks apart between 19 Aug and 16 Oct 2024. Then there is a 2.5 month leap to Dec 2024, and then all the way to Jul 2025. I don't understand light echo. Credits below 🔭.
