Astrophysicist and Planetary Scientist. Professor at the University of Arizona. Fellow, American Astronomical Society. Outdoor enthusiast with a love for hiking, biking, and dogs.
Glad to have toured the Stratospheric Observatory for Infrared Astronomy (SOFIA) at the Pima Air & Space Museum. Amazing to see the aircraft that carried infrared astronomy above the clouds, I almost got the chance to fly on it.

‘An Overview of Exocomets’ is a very comprehensive review led by Daniela Iglesias started at an @issibern.ch meeting. I worked on Figure 1 detailing comets around the Sun, Beta Pic and a white dwarf - I’m very proud of it, and it is available on @github.com: Exocomet systems #astrodon #exoplanet ☄

Seeing some beautiful photos of aurorae tonight, so here's a reminder that other planets get them, too!
This is Saturn, with aurorae visible at both poles in this UV image from Hubble's Space Telescope Imaging Spectrograph, taken in October 1997 when the planet was 1.3 billion km away.

Here is the Nebra sky disk, considered by some the oldest known illustration of the night sky.
The artifact was discovered near Nebra alongside several Bronze Age weapons and is linked to the Unetice culture, which thrived in parts of Europe...

This weekend I read that the entire Breaking Bad franchise is estimated to have had $385M in economic impact for the state of NM and this is celebrated by a statue at the ABQ convention center. Meanwhile University of Arizona space science has an economic impact of $560M on our state every year.

Congrats to my student Dingshan Deng on a new paper! 🎉 A self-consistent thermochemical model to measure disk masses, fully consistent with dynamical estimates – no need for ×100 CO depletion! Enables reliable disk-mass estimates for many more stars. #ALMA #Astronomy @uarizonalpl.bsky.social

This is devastating, and part of a larger move to entirely push science out of NASA's mission. It is horrific betrayal of so much work, not to mention the fact that it violates NASA's charter.

NASA’s charter clearly states the agency should study planet Earth, however.

It’s depressing how much faster it is to break a thing than it is to build it

Call it millennial cynicism if you like, but I truly believe nothing will turn the Republican base or leadership against Trump. Our only hope is getting young voters to turn out for elections, and every march/petition is useful only if it serves that goal.
The Republican megabill cuts trillions in taxes, while scaling back spending on Medicaid and other federal programs. It now heads to the House, where some GOP lawmakers are signaling major objections.
