The TRAPPIST-1 planets now have the best measurements of any set of terrestrial planets other than our Solar System... and they look different than our terrestrial planets. With Caroline Dorn @Nonomamades @ElsaDucrot @LaetitiaDelrez Michaël Gillon @AbVsm @brettmor @fselsis +++
ARCHIVED NASA Exoplanets@NASAExoplanets

The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found. Now we know even more about the densities of these seven rocky worlds. And the composition of the TRAPPIST-1 planets could be notably different than Earth's! go.nasa.gov/3c78qST

Can you tell which twin is which? I feel privileged to have met these gentlemen - thanks for serving our country. (Not sure who took the photo, but I think it may have been Gabby Giffords.)

I computed a model for the appearance of a supermassive black hole (right), which was confirmed twenty years later with the Event Horizon Telescope (M87 on left; Sagittarius A* middle).

4 out of 9 Noble prize winners in STEM fields this year are from the University of California system. Two from UC Berkeley (John Clarke and Omar Yaghi) and two from UC Santa Barbara (Michel Devoret and John Martinis). Incredible concentration of scientific expertise.

The statue of Pasteur in Paris faces the Invalides where Napoleon is buried. This is apt as one fought germs, while the other fought Germans.

Mario Livio@Mario_Livio

Today Sept 28. #OTD in 1895 chemist Louis Pasteur passed away. Renowned for discoveries of the principles of vaccination, microbial fermentation, and pasteurization. His research led to remarkable breakthroughs in the understanding of the causes and preventions of diseases.

Sorry @Wikipedia and @Google but this is not correct. Half of the Nobel prize was awarded to Penrose for the mathematical theory of black holes; the other half to Genzel & Ghez for their study of Sgr A*. (Thanks @NYTGames Connections for alerting me to this!)

RIP William Paxton, the founder of the MESA stellar structure and evolution code.
Simons Foundation@SimonsFdn

One of the most important contributions to the study of how stars evolve didn’t come from an astrophysicist, but instead a computer scientist. Bill Paxton — who died last month — revolutionized the field by creating the Modules for Experiments in Stellar Astrophysics (MESA).

@loiseau_jc I've found Julia to be a nice replacement for FORTRAN, with a REPL which makes interactivity possible as well @JuliaLanguage

Had an interesting discussion with a colleague about the merits of #Fortran and #Python for an undergrad class (ME not CS) on numerical linear algebra. Having just migrated my personal webpage, I figured I'll start a technical blog and write about it. 👉 tinyurl.com/3a4dfcnu

Whether planet e has an atmosphere is still TBD. Researchers are still observing it, and think its primary atmosphere is gone, though it could have a heavier secondary one. go.nasa.gov/3VBE3cL

The LIGO Scientific Collaboration will greatly miss our friend and colleague, Professor Rainer Weiss, whose immeasurable impact on gravitational-wave astronomy will be felt for generations to come ligo.org/professor-emer… Our thoughts are with Rai's family and friends

At the University of Wisconsin–Madison, we are excited to host 51 Pegasi b Fellows in the Department of Astronomy! Applications are due October 3, 2025. This was the fellowship that I had as a postdoc, and I’d be happy to chat if you think you might be interested in applying!
