This is good advice for prospective PhD students. I'm getting a ton of emails that are heavily written by AI. If you can show that you've actually read some of the research yourself and have a few original thoughts about it you'll definitely stand out.

Hi my Bluesky community. I am the worst sleeper. I always have been, but I have gotten much worse lately. I need a little social pressure to deal with it. Encouraging stories of positive change welcome.

Check out this MASTERPIECE of accessibility from Joop Schaye's group - a gorgeous sonification of a galaxy growth simulation. Hear black holes merge, star formation rates rise and fall, and the whoosh of dwarf galaxies flying by. Beautiful AND informative! (Credits next post!) (📣 Sound on! 📣)

Small moment of Zen on my morning walk with Captain Fluff. Sound up for birds chirping. Merced is dry but so beautiful.

Infrared light highlights warm dust and bright star clusters in this image of galaxy NGC 5134 captured by #NASAWebb. Billions of small stars create the galaxy’s faint blue glow. Credit: NASA, ESA, CSA, A. Leroy.
A spiral galaxy, seen tilted diagonally from upper left to lower right. It has a blue-white, glowing spot at its core. Its oval-shaped disk glows faintly blue throughout with light from its many stars. The disk is filled with waves and strands of bright red dust that swirl around the core. At places there are holes torn in the dust, while elsewhere it forms dense clumps that glow orange. Several tiny, distant galaxies appear across the background, which is black.

Crazy lightning storm over UC Merced tonight. Breathtaking is an understatement.
A bright flash of lightning shines in electric blue on the top, contrasting the yellow street lights illuminating a walking path on the bottom right. Between some soggy tennis courts shimmer purple blue at UC Merced.

Enjoyed a beautiful Saturday morning hike with Captain Fluff (who was a most excellent doggo). Saw a beautiful murmuration and lots of wildflowers too. I hope you all have a chance to experience some beautiful nature today too. #MorningWalk
Big black fluffy German shepherd with pointy ears and a floppy tongue stretched out and relaxed in a field of small yellow daisies, with a few small white flowers and long grass behind and to the left of him, framing him and providing a little shade. Moments later he had a huge bowl of water (not pictured) for an hour hike well done. Excellent doggo.

Merced, CA this morning. #MorningWalk
A big, black German Shepherd runs down a long straight dirt road, which fades into the distance. Sun bleached long grass grows in fields on either side, lined and is separated from the dirt road by a thin barbed wire fence. Very blue sky and white clouds fill the rest of the field of view. A calm, quiet and largely empty place for dog and owner to have a morning walk.

Our wonderful dog, Captain Fluff, through a series of unfortunate events got a sunburn 1.5 months ago. To aid in his skin recovering, our vet has been giving him periodic laser treatment, and Fluff has to wear goggles for the treatment. He *loves* the experience so much. Our vet happily shared this!

Feeling so moved 💫 This 3,000-piece LEGO Milky Way—complete with our solar system’s location + a LEGO Gaia telescope—was assembled + gifted to me by Steven Umbarger, an amazing UC Merced graduating senior heading to UMich for his PhD with fellow LEGO lover Eric Bell. I’m so grateful. 💙
A completed LEGO Milky Way galaxy display set. The intricate build features thousands of small colored pieces to represent spiral arms, star-forming regions, and the central bulge. A tiny LEGO Gaia telescope is included on the model, along with an arrow labeled “You are here” pointing to the solar system’s approximate location. The whole display is colorful and detailed, capturing the structure of our galaxy in LEGO form.

This is a terrible budget proposal for NASA. While some cuts are justifiable, the largest part of the $5B cut comes out of space science including eliminating funding for "low-priority" climate monitoring satellites. Eliminating climate change research funding doesn't make the problem go away.

Fun facts about physics & astronomy, according to the American Institute of Physics (AIP): Fewer than one quarter of astronomy faculty or instructors, at any rank, are women. Fewer than one in five physics faculty or instructors, at any rank, are women. (Source links in 3/3) 🔭🧪 1/3
An infographic table from the AIP website:

Percent of Astronomy Faculty Members Who Are Women, 2010 to 2022

In 2022, 17% of full professors, 37% of Associate Professors, 35% of Assistant Professors, 35% of Instructor/Adjuncts, and 18% of "other ranks" were women. Overall, this is 23% women, and down from 2020's overall of 27% (matching 2018's rates).

But this theorist is going to try to learn something new; I bought a Coronado PST Solar Telescope. Will students & I be able to use it? Stay tuned.
