#BlackHoleWeek2025 🌀 Black hole Sagittarius A* from optical🔭 to radio wavelengths📡#EHT📡 @ehtelescope
Recent research led by our astronomer @jayender_singh has changed our understanding of the Milky Way's inner structure. This part of the galaxy is notoriously hard to study, but these new insights are redefining the shape of our home galaxy: iopscience.iop.org/article/10.384…
🚀 Turns out, the so-called "Expanding 3 kpc arms" of Milky Way are: ❌ Neither expanding ❌ Nor at 3 kpc ❌ Nor spiral arms Our new paper reshapes our understanding of the Milky Way’s inner structure—watch as @SimonEllingsen breaks it down! 🌌 linkedin.com/posts/internat…
VLBI at @prcnaoj_en Mizusawa
Traveling to @naoj Mitaka and Mizusawa VLBI observatories from Kagoshima via Shinkansen. Pretty awesome actually 🗾📡🚄
Among beautiful Perth beaches, delicious food, and my fav person in the world!! 😎🏝️
Graduations are always special events🎇 Even more so when you get to celebrate with people you have worked closely with for many years. Congratulations Dr Kumar aka @jayender_singh
And the four #Gaganyaan #astronauts are: Gp Capts Prashanth Nair, Ajit Krishnan, Angad Prathap and Wing Co Shubhanshu Shukla. I'd got three of the four names out in today's TOI, correctly indicated by sources outside of @isro. One name (Chauhan) was off. All four are test pilots
BREAKING: India announces the 4 Indian astronauts for the #Gaganyaan mission to space. The four chosen IAF pilots are: Gp Capt Prashanth Nair Gp Capt Ajit Krishnan Gp Capt Angad Pratap Wg Cdr Shubhanshu Shukla Big congratulations to the 4 and their families!
Congratulations @jayender_singh on formal acceptance of your PhD thesis. So you're now officially Dr Kumar! A nice note on which to finish the working year
Congratulations to @isro for the successful landing of the #Chandrayaan3 mission at the lunar south pole and deploying a lunar rover. It's starting to get really busy on the Moon. Did you know that radio communication to the moon needs antennas of around 20m or bigger?
Chandrayaan-3 Mission: 'India🇮🇳, I reached my destination and you too!' : Chandrayaan-3 Chandrayaan-3 has successfully soft-landed on the moon 🌖!. Congratulations, India🇮🇳! #Chandrayaan_3 #Ch3
Chandrayaan-3 Mission: The mission is on schedule. Systems are undergoing regular checks. Smooth sailing is continuing. The Mission Operations Complex (MOX) is buzzed with energy & excitement! The live telecast of the landing operations at MOX/ISTRAC begins at 17:20 Hrs. IST…
Final PhD presentations are always a proud supervisor moment - excellent work @jayender_singh! They are also bitter-sweet when valued team members move on to the next stage of their careers - all the best @CSIRO_ATNF 📡

Very nice talks today from @jayender_singh on direct measurements of the Milky Way bar and Lucas on new southern parallax results. Friday morning, first talk after the conference dinner is when I get my turn 🤔

Another busy week! On Monday Guifré attended the @AusSpaceAgency industry event with senior NASA officials. While @jayender_singh, Lucas Hyland and @SimonEllingsen are at #IAUS380 in Japan presenting the ultra-precise astrometry results from the @UTAS_ @AuScopeVLBI array.
Radio astronomers have used Very Long Baseline Interferometry and parallax. Parallax is a way to calculate distance by looking at an object from two different positions. (2/🧵)
