We asked Ed β€” how do we talk up the benefits of science in the face of government cuts? He told us that's the wrong approach. πŸ§ͺ

Figure from the paper showing detected streams in the Milky Way in Cartesian coordinates, where streams are shown as highlighted volumes. The Sun is at X=Y=Z 0 pc (the red cross): so these streams are all around us!

What happens when a star cluster disperses? Well, it forms a stream of stars - and those streams are all around us!

In a new paper by Sebastian RatzenbΓΆck at the CfA / @univie.ac.at, we looked into streams near to the Sun, and found that the Milky Way's disk is *full* of streams! πŸ”­β˜„οΈπŸ§ͺ #galactic

This β€˜blue states closed schools too long’ narrative is becoming increasingly entrenched in the Polite Center but it’s arguable at best.

Republican states had far more deaths during COVID and their students have roughly comparable learning loss.

NSF Astronomy and Astrophysics Postdoctoral Fellowships (AAPF)

Hi astro πŸ”­ sky, I heard that the NSF Astronomy & Astrophysics Postdoc Fellowship (AAPF) is not being offered this year. Is that correct? I know it was cut in the PBR, but I wasn't sure what that meant in practice. Typically app would have opened Aug 15. www.nsf.gov/funding/oppo...

Ethan Vishniac to Step Down as Editor in Chief of AAS Journals in 2027 | American Astronomical Society Dr. Vishniac’s retirement will mark the end of a 12-year term, during which he has led the journals through a period of remarkable growth and innovation.

Some personal news.

Announcing one’s retirement two years in advance may strike a lot of people as excessive notice, but I expect the search for my successsor to be time-consuming (and I was determined not to extend my tenure beyond the announced date).

It's a GI program for funding and cadence. Some TESS programs are also for time on other telescopes (simultaneous observations), but most are for funding or to get certain targets at the faster download.

That's why it's a weird situation to in - funding is the MAIN output of the TESS GI program.

Apparently zero TESS proposals were "selected" because they don't know about funding. Best ranking you can get is "selectable". πŸ§ͺπŸ”­ #exoplanets

Spoken like someone who has never actually tried to make such a call to a university admissions office.
I've been at multiple institutions where tiny changes (like not accepting GRE scores) took 1-2 weeks of emails.

We were able to get the application portal closed for the astronomy graduate program at @michiganstateu.bsky.social for the upcoming cycle. Not an ideal circumstance, but we wanted to communicate this to the community as early as possible.

Little do you know that the easiest form of interstellar space travel is just hopping on existing interstellar comets. For that reason any comet-like thing furthers my hypothesis and any not-comet-like thing also furthers my hypothesis.
