We’re excited to announce the successful completion of the Secondary Mirror (M2) Metrology & Polishing Equipment Final Design Review!
@UAZOpticalSci has been leading this work since Spring 2025, developing the advanced tools needed to meet the mirror’s demanding optical requirements. At 3.13m & 2000kg, our M2 will be one of the largest convex mirrors ever created!✨ #NSFfunded @nsf

#OTD in 1987, astronomers spied a bright flash in a neighboring galaxy. The event, called SN 1987A, remains the closest supernova in over 415 years and is one of the best opportunities to study this type of stellar death. More: https://t.co/Zep65ag2b5
Congratulations to all the winners of the #CongressionalAppChallenge! 🌟 We were excited to sponsor gift bags with TMT swag for the talented contestants from California’s 28th Congressional District. It’s always inspiring to see young innovators showcase their passion for coding and technology!
Congratulations to the 2025 #CongressionalAppChallenge winners from #CA28!
I’m astonished by the talent behind each submission, showing the importance of STEM education for our youth. Thank you to every young coder who participated this year! @CongressionalAC
I’M RETURNING FROM HIATUS!!!!! 🥳🎉
To celebrate, we'll be building a telescope!🔭
Well… a 1/500 scale model of the upcoming Thirty Meter Telescope! 😅♥️ @TMTHawaii

The #AAS247 winter session is coming to a close after an engaging and astronomy-filled week. Thank you to @aas_office, our US Extremely Large Telescope Program partners, and all meeting participants. @giantmagellan @TMTHawaii @NOIRLabAstro
Another great meeting at #AAS247 thanks to @AAS_Office! It was a pleasure to be part of the #USELTP booth hosted by @NOIRLabAstro, where we had many engaging conversations about the Thirty Meter Telescope. Thanks to everyone who stopped by, whether to catch up on the latest TMT progress or to learn more about its far-reaching scientific capabilities.✨
We’re excited to be at #AAS247 in Phoenix with @aas_office!
Stop by the US Extremely Large Telescope Program booth to pick up some astro swag and chat with our experts.
