So I'm seriously considering looking outside the US in my attempt to get into an astro grad program. Most places outside the US require an MS, so my options are a) find a master's program in the US, b) attempt to get into a US PhD program again, or c) find an international MS. Any recs/advice?

Our closest spiral galaxy neighbor, sitting about 2.5 million light years away. Captured with my Seestar S30 telescope and processed in Siril, Graxpert and Lightroom. This is 3.5 hrs of data and I will continue to add to it. #astronomy #space #universe #astrophotography @kat-astro-bot.bsky.social

M4 is a globular cluster located about 6 kly away in the constellation of Scorpius.
Studies of the motion of stars in M4 suggest that there is an 800 Solar mass object at its centre. This could be a intermediate mass black hole. #astronomy

🌙 The crescent Moon is currently near the M35 star cluster in the pre-dawn morning sky. M35 is located near the feet of Gemini. Closest approach is at 0h UT on August 19th. Use a pair of binoculars at a dark sky site for the best view. 🔭

The Bubble Nebula, in the constellation of Cassiopeia. The bubble itself is a shell of material cast off by the intense winds of the bright star SAO 20575 inside. The radiation also illuminates a vast cloud which surrounds the region, causing it to glow the characteristic red of ionized hydrogen. 🔭

Question for the radial velocity #exoplanets experts:
Is there an animation that shows two spectra being shifted with respect to each other and the corresponding values of the cross correlation function changing?
I think I’ve seen one in a talk but can’t find a nice animation online

The SETI Institute's Allen Telescope Array (ATA) recently played host to 16 scientists, engineers, and technologists who gathered for a three-day "hackathon" to develop novel capabilities for the observatory. 🧪 🔭

Data that taxpayers have paid for and rely on is disappearing. Here's how it's happening and what you can do about it
People rely on data from federal agencies every day—often without realizing it.

I was hoping for at least two more nights on this guy but that hasn’t happened yet so I thought I’d post what I have for now. I believe it’s coming along nicely though.
Here is vdB 152 aka Wolf’s Cave, or as some have called it, the Penguin. Just another dark nebula from the constellation Cepheus. 🔭

It's full of stars! Almost forgot the awesome feeling standing under the Milky Way & seeing its structure. I miss these skies.
Comet C/2025 K2 (ATLAS) is still moving quickly. 11.8 mag, Dia 1.4', DC5. Next estimate tomorrow night. The image does NOT show the comet, just a quick smartphone shot.

I'm excited! Having a meeting at DIN Berlin tomorrow and will spend two nights at my childhood home in the Erzgebirge Mts with my mother. I have brought the 10" Dob with me & will observe comet C/2025 K1 tonight under the dark skies I was used to between 1987 and 2000. Sky looks already good! 🔭☄️

📷 This NASA/ESA #Hubble Space Telescope image shows spiral galaxy NGC 2835. This image differs from previous images of NGC 2835 because it contains new data from Hubble for a specific wavelength of red light called H-alpha. Read more👇🧪🔭

As the weather isn't great, decided to have a look at old #astrophotography data I've taken instead: I went back to my first ever big project, just after I moved out to dark skies...the Veil Nebula.
Took this over 8 hrs on 2 nights on an unmodded DSLR.
Not bad at all! Description in ALT

Been working for quite some time to get a shot like this one. Loads to luck and planning after an utter failure the previous night. Can finally check this off the list. Captured Cygnus over our holiday rental last night. #astrophotography #space #milkyway

Supernova SN 2025rbs in the galaxy NGC7331 from yesterdays short #Astrophotography session.

Here is SS 433, the first identified microquasar.
It is about one of the most exotic star systems known, a binary star microquasar consisting of a stellar-mass black hole and its companion, a giant star.
The star is about 30 solar masses, ...

Haha, no, you don't lie about observations. ;) Although I have seen Venus, Jupiter and Saturn on other occasions this summer. 🪐🔭🐸
