I am now observing WD1856B using NIRSpec Bright Object Time Series for 2 hours and 22 minutes. Keywords: Exoplanet Systems, Exoplanets, White dwarfs. Proposal: stsci.edu/jwst/phase2-public… 1:1
Bad product idea: A password manager that only uses long strings of capital "I"s and lowercase "l"s.
Maybe they're having Sam Seaborn rewrite POTUS' remarks 'cause the NASA Pub Aff writer said "very unique" #TheWestWingSpaceTelescope
Surely there are already people out there choreographing TikTok dance routines set to the #JWST hold music
Eeeeeeeeek! A new friend for @WD1856_534b!
Astronomers reported observing a tantalizing preview of our solar system’s afterlife: a Jupiter-size planet orbiting a white dwarf some 6,500 light years from here. The discovery hints that life on "survivor" worlds may endure the deaths of their stars. nyti.ms/2YN4get
Things that physics instructors should avoid #372: Giving a pantomimed demonstration of how a dashpot works using one's hands. 👉👌
"but abolishing the police is bad politics" - so is the murder of children, in less perverted societies

Imagine thinking the people who care about the murder of a child are radicals and that the people who argue for impunity for the murderer are the moral ones.

The coming weeks are likely to be important for the future of ground-based astronomy in the face of the threat of satellite constellations. How is it a threat, what are astronomers doing, why are these weeks important? Thread 👇
This one goes out to everyone who has ever tried to convince an astronomer that astrology is "harmless fun" and to every astronomer who has been called "close-minded" for pointing out that it's crap.

Even if you're fully vaccinated, the CDC still recommends that you begin your exoplanet paper by citing the astonishing and baffling discovery of 51 Pegasi b (Mayor & Queloz 1995)
I feel a great disturbance in the Force. As if hundreds of astronomers on Twitter just read this comic and cringed. File it under #JWSTMemes, I guess.

FLUID DYNAMICS, holy crap. Normalize it as part of a grad Astro curriculum. Everything is *basically* a fluid on at least some scales. Traffic? A fluid. Hundreds of billions of stars? A fluid.

ERES is back!!! To be held virtually May 24-May 26, 2021. The deadline to apply is April 2nd. Early career exoplanet scientists are especially encouraged to apply. Go here for details and application form: eres2021.com
My grad program's Friday social video call spontaneously became a thoughtful, respectful group debate about the need for major reforms in US higher-ed. Good reminder of both what the pandemic has taken away and what we'll need to do when it's over. #AcademicChatter

Every astronomer needs to watch this excruciating video. Jill Tarter is a pioneer and this is how he treats her?
@CenterForAstro has hosted some of my favorite people, but if they continue allowing this then I will do all that I can to stop people I care about from going there

Further proof that some of the most exciting exoplanet science is happening in two places: around white dwarfs, and at my alma mater @UCLA!
Paper 1 (Klein et al.): arxiv.org/pdf/2102.01834.pdf
Paper 2 (Doyle et al.): arxiv.org/pdf/2102.01835.pdf
These studies together (1) report the first detection of the element beryllium (Be) in the atmospheres of polluted WDs and (2) propose that the Be came from the icy satellites of giant planets orbiting these stars.
