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%.

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

Digital art with a circular nebula in the center colored pink and blue. On top is a bird with an orange breast - about the same size as the nebula.

Happy LGBTQinSTEM Day!! I just ordered a pin for myself and a pin for my trans femme partner who is also called Robin... I hope she never gets sick of my robin themed cards and gifts... Like this card I painted digitally with the robin's egg nebula. 🐡

LOVE IT!

I look forwards to seeing what the Vera C. Rubin observatory will help reveal about the universe.

Here is a timelapse (condensed into 30s) of my artwork from the software I use, Procreate (on ipad). #sciart

In June, @harvardplatestacks.bsky.social held an event celebrating a new U.S. quarter honouring Dr Vera Rubin. Her colleagues and granddaughter shared stories: Vera was not only an amazing scientist, but she was also warm, down-to-earth, loving, curious, and an advocate for women astronomers. (4/5)

Dr Vera Rubin changed the way we view the universe. Her meticulous observational work showed that galaxies were rotating faster than expected. Her work convinced scientists that dark matter must exist, and that there’s far more of it than regular matter. 🌌 (3/5)

Trifid and Lagoon Nebulae | Rubin Observatory Get a Rubin's-eye view of the Trifid and Lagoon Nebulae

The inspiration image was created in May 2025 and combines 678 separate images, allowing us to see the faintest details. The picture shows the Trifid nebula (top right, blue) and the Lagoon nebula (central, pink). You can read more about them here: rubinobservatory.org/news/rubin-f... (2/5)

digital art with an orange, yellow gaseous background, a central pink elongated nebula, and a top right pink and blue circular nebula. Lanes of dark brown dust clouds are across the image.

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)

Thank you Jonathan for your decades of work shaping such an amazing program! Very cool to think about/see how many people's lives you've influenced.

Wowowow! That was quick! These look incredible!

It's finally here! We've just released all of our COSMOS-Web images and catalogs, along with an interactive viewer where you can explore the data! Check it out at: cosmos2025.iap.fr

You can find a list of Christian's publications here: orcid.org/0000-0002-88...

Congratulations, Dr. Groeneveld!

Digital artwork depicting the Perseus galaxy cluster as a swirling, abstract formation. A bright white core is surrounded by turbulent, filament-like structures in shades of green, blue, and soft white, suggesting the presence of radio halos. The outer edges blend into a glowing green aura, evoking the sense of motion and energy from cosmic turbulence. The image symbolizes the invisible structures seen in low-frequency radio observations of galaxy clusters.

Christian’s research focused on the Perseus galaxy cluster. They confirmed two giant structures: a radio "mini-halo" around the central galaxy, and a much larger "giant radio halo" over a million ly! These halos likely come from turbulence caused by past cosmic mergers, which re-energize particles.

Back cover of a PhD thesis featuring a background of real LOFAR decameter-wavelength radio data in dark green tones, overlaid with four bright blue-white objects representing active galactic nuclei (AGN). These AGN appear as luminous, irregularly shaped sources with glowing cores and faint jets, distributed across the frame. The background is textured with starburst-like calibration artifacts centered on numerous faint point sources.

Studying space at such low frequencies is incredibly challenging because the Earth's ionosphere distorts the incoming radio waves. Christian helped develop a new calibration technique that enables higher sensitivity and resolution imaging at these wavelengths.

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.

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!

These are great! I would put prints of a set up in my office.

This is so great 😍😍

Hi Bunny! What a fabulous idea - it would be an honour to collaborate. I'll DM you.

Aww thanks for the sweet words! I'm so happy you like my art. Yes, please repost with credit :-) 🙏

I was asked to give my social media accounts when applying for my work visa last fall.

I hope so too Susan. I think too often scientists try to remain applitical and (are told to) "stick to the science". I try to remember that science is (and has always been) political and we scientists are also (first and foremost) humans.

painting of the pillars of creation in visible light. The 3 pillars are dark brown and block the light.

The pillars of creation were first made famous when imaged by the Hubble Space Telescope in 1995 (and again in 2014) in visible light - which I have previously painted. The near-infrared view from JWST helps us peer through more of the dust - revealing many more stars that are forming within.

painting of the "pillars of creation". The three pillars are brown, but also have red and yellow colours

My mini painting of the Pillars of Creation was inspired by the JWST NIRCam image. This region of active star formation lies ~6,500 lyr away. Glowing red lines near the edges of some pillars reveal where stars are ejecting material as they form. 🔭🧪 🎨
