Last year I had the pleasure of designing the cover for Stefan van der Giessen's thesis titled "The resolved lifecycle of metals and dust in nearby galaxies." For his PhD, Stefan combined multiwavelength observations of nearby galaxies with hydrodynamic simulations and chemical evolution models. 🔭🐡

Well to the surprise of absolutely NOBODY, the Australian University Census on Staff Wellbeing found that the sector is (to put it mildly) a bit fucked when it comes to psychosocial safety climate, with 44% of respondents in a very high risk environment. #AcademicSky

a figure displaying survey respondents and their placement in low, medium, high, or very high risk environments. Benchmark figures are between 54 and 62% low, and 11-12% very high. The census in question has a low risk placement of 18%, and a very high risk placement of 44%.

New frontiers 🔭🎨 This art was inspired by one of the first images released by the Vera C. Rubin Observatory. The Rubin Observatory will capture images of the entire sky every few days using the 3200 megapixel LSST camera, allowing astronomers to identify and study targets that move or change. (1/5)

Today, my colleague Christian at Leiden University successfully defended his PhD thesis, "Galaxy Clusters in the Decameter Sky"! In it, he mapped the sky at a relatively unexplored range of radio frequencies—10–30 MHz—using the LOFAR telescope. I had the honour of designing Christian’s thesis cover!

Cover of a PhD thesis titled "Galaxy Clusters in the Decameter Sky" by Christian Groeneveld. The background features real decameter-wavelength radio data in glowing green tones, filled with faint point-like sources. At the center is an abstract, swirling digital illustration representing the Perseus galaxy cluster, with luminous filaments and a bright central core, evoking the turbulent energy of radio halos.

Hi bluesky 👋🏻 We're a brand new 501(c)3 non-profit that works at the intersection of neurodiversity 🧠 and space science 🚀 If you're neurodivergent and in space aligned fields/interests, then we are here to help you!! FOLLOW US here so you're the first to know when we roll out our programs!

Check out this article from STFC about our sonification of astronomical data, and beyond! including a new sonification at the end - perceive multi-scale information about galaxy formation in our cosmological simulations... 🧪🔭⚡🐡. medium.com/big-science-...

The sound of silence: how sound brings space to life

The vacuum of space is famously silent, but what if you were able to use sound to help you visualise the Universe? What would a black hole…

April is both PMDD and Autism awareness month. It was cool to see a man talk about this topic! youtu.be/qPhWVC9vjl4?... If you think you might have PMDD, I highly recommend the IAPMD (international association for pre menstrual disorders) website for more resources and latest research.

Understanding the Impact of PMDD on Autistic Women

Hi! I'm Orion Kelly and I'm Autistic. On this video I explore the topic of PMDD and it's impact on neurodivergent women. #orionkelly #autism #asd #autismsign...
