Three #NASAWebb discoveries in ONE! Webb shows there are FOUR dust shells (only one was previously seen), allowing researchers to narrow the stars’ orbit of one another to a LONG 190 years. Plus, they confirmed a third star is part of the β€œparty”: https://bit.ly/4n1tpas πŸ”­ πŸ§ͺ

I put forward a simple amendment to the government funding bill that would’ve extended health care tax breaks to give folks some breathing room.

Pre-ACA, I was a postdoc on an NSF fellowship at a university that didn't offer employment benefits to independent fellows. At that time, being a woman meant that my premiums were double that of my male counterparts. The extra cost came out of my grant's budget for benefits, equipment, and travel.

Solar, Stellar and Time-domain Astrophysics Star formation and Stellar Evolution PhD Projects.

The @herts.ac.uk astronomy MSc and PhD applications are open.

I'm offering PhD projects on JWST spectroscopy of young stars in Tr 14 and star-cluster formation.

I'm also offering an MSc project on variability of YSOs.

Astronomers from the International Centre of Radio Astronomy Research (ICRAR) have created one of the largest low-frequency radio colour images of the Milky Way ever assembled. This spectacular new image captures the Southern Hemisphere view of the Galactic Plane – the disk of our Galaxy, which appears to human eyes as the glowing band of the Milky Way – now revealed across a wide range of radio wavelengths, or β€˜colours’ of radio light.

This is what the band of the Milky Way would look like at night if your eyes could see radio waves. A hidden beauty.

It's a new image created by the Murchison Widefield Array, which scanned the sky in 20 radio "colors" over frequencies from 72 to 231 megahertz. πŸ§ͺπŸ”­

This image captures a richly detailed section of the Milky Way, showcasing a tapestry of stars and glowing nebulas. Against a deep black cosmic backdrop, countless white stars sparkle like scattered diamonds. Wisps of reddish-pink nebulas drift across the scene, forming delicate tendrils and cloud-like structures.

Picture of wood beams crisscrossing the underside of the roof in a conference room. The photo is at a jaunty angle, catching the edge of a tall slide, and the ceiling below the beams where the projector is mounted. A white circle is drawn to indicate the presence of a fluffy gray tail among the beams.

I don't post a lot, but I am particularly proud of this paper. It's the first observational sample of binary companions to stripped envelope supernovae. And places constraints on the binary evolution physics.

It only took me 10 years to build with HST!

A Hertzsprung-Russell diagram (i.e. relationship between colour and brightness of stars) for ~1200 open clusters. Gaia magnitudes have been dereddened. The points show member stars in the clusters, colour-coded by age. The outlined regions show areas with variability based on Gaia DR3, labelled by Gaia class name.

Always fun to look at accepted HST programs. Hats off to David Thilker (STScI) with a title that doubles as a cry for help: β€œOur grasp of star formation, feedback, and galaxy evolution is incomplete without a JWST+HST look at the HI-dominated, outer disk of a spiral galaxy”

Hear, hear! Good luck!
