On December 2, 2018, we captured comet 46P/Wirtanen ☄️during its close approach to Earth—just 11.4 million kilometers away, about 30 times the distance between us and the Moon. 😉 Have you ever seen a comet in the sky?☄️

Congrats to students Raphael Baer-Way and Eliza Hillenkamp on being awarded prestigious Graduate Research Fellowships (GRFP) from the @NSF! They've been working with NRAO's Poonam Chandra on multiwavelength studies of interacting supernovae, using VLA/GMRT/Chandra combined data.

The submission deadline for Semester 2026A proposals is Wednesday, July 30, 2025, at 17:00 EDT (21:00 UTC). science.nrao.edu/observing/call…

I Love Lamp 💡 Outside the @almaobs ALMA Operations Support Facility (OSF), fixtures are used sparingly to prevent light pollution. As you can imagine, none of these stars would have been visible if the light were on! 📸 Credit: NSF/ AUI/ NSF NRAO/ B.Foott @bettymayafoott

📡The TPGS will significantly improve ALMA’s capabilities. It will feature: ✅Four times more correlated bandwidth ✅16 times finer spectral resolution ✅Ten times higher input data rate from antennas 🔗almaobservatory.org/en/announcemen…
