✨🔭🧪 with STScI postdoc Jimena Rodriguez! where we search for dusty star clusters in 19 nearby galaxies using the PHANGS-JWST Treasury Survey, and find a very short timescale (<3 Myr) for the dust embedded phase. Fig 17 & 18 are my favs!

Relieved to report that our PHANGS paper has finally been accepted for publication in ApJ! To our knowledge, this is the first census for dust obscured star-formation at the star cluster scale across a broad set of nearby galaxies. 🧵[1/n]🔭🧪#extragalactic

NASA’s Habitable Worlds Observatory will do more than hunt for life in the 2040s.
This summer scientists put forward 100 ideas for the ‘scope including planetary defense, studying Venus, and even observing individual stars in distant galaxies.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

One of my faves, among the galaxies that we're studying. Uncommonly beautiful because of its striking "flocculent" spiral morphology. We've learned its star clusters tell a story of gas accreted from a neighbor, rejuvenating the disk🧪🔭

Spiral, elliptical or neither? 🤔
The latest image from the NASA/ESA Hubble Space Telescope features a hard-to-categorise galaxy, NGC 2775. It has features of both elliptical and spiral galaxies – so what type is it?

The White House is proposing steep cuts in NASA’s science program that, if implemented, would cancel several major missions, contradicting claims by the administration’s nominee to lead the agency.
