✨ TMT: Where the Universe Comes into Focus ✨ On May 30th, TMT’s Fengchuan Liu and Dave Andersen hosted a webinar diving deep into the science and engineering behind the Thirty Meter Telescope. They discussed how TMT’s design has been optimized to deliver groundbreaking science

In relation to the NSF FY2026 budget request, several Japanese academic societies have sent letters of support strongly endorsing the promotion and realization of the #TMT project. English translations of the letters are available at the following link. tmt.nao.ac.jp/info/1929

The #AAS246 summer 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. Giant Magellan Telescope TMTHawaii NOIRLab

#DidYouKnow… TMT found the sweet spot between image clarity and field of view! 🌟🔭 Adaptive Optics (AO) helps telescopes cut through the blur of Earth’s atmosphere, and while most AO systems specialize in either wide views or sharp images, TMT’s multi-conjugate AO (#MCAO)

#TMT’s Dave Andersen recently attended the Canadian Astronomical Society (#CASCA) conference in Halifax, 🇨🇦 where he provided a project update including community engagement in Hawai‘i, design maturity, and comparative performance advantages. Learn more about these topics in our

Congratulations to NSF-DOE Rubin Observatory on their fabulous first look images! Your surveys are set to uncover unprecedented phenomena across the cosmos, providing the data to answer many major questions in astrophysics and unlock countless new questions that will require the use of the next

TMT is eager to follow up on NSF-DOE Rubin Observatory discoveries, providing the ultra-high-resolution, high-sensitivity spectroscopic, and rapid-response observations needed to fully characterize the faintest and most distant objects revealed. ✨ From understanding the evolution of galaxies

🌟Major milestone for TMT’s Secondary Mirror System!🌟 The Secondary Mirror Support System and Positioner Assembly, designed by AMOS 🇧🇪 and ADS-International 🇮🇹, recently passed its Final Design Review! This system is key to precisely positioning the 3.1m secondary mirror which

#DidYouKnow… Mounting NFIRAOS, TMT’s adaptive optics system, on the Nasmyth platform unlocks major performance advantages! Why? Because the Nasmyth platform remains fixed no matter where on-sky the telescope is pointing. 🔭 This keeps gravitational forces on NFIRAOS consistent

We appreciate the invitation from the Gov't of Spain and their €400 million commitment to host TMT in La Palma, Canary Islands. This show of support is a positive development and reflects continued international confidence in the project. While no final decision has been made,

We had a great time at last week’s Habitable Worlds Observatory (HWO) conference! A highlight: TMT Optics Lead Ben G. spoke to 400 attendees about segmented mirrors, earning applause as the person behind JWST’s mirrors. That legacy lives on in HWO, which builds on technologies

Another milestone for #TMT! 🌟 The Tertiary Mirror Support System has passed its Preliminary Design Review! This subsystem plays a vital role in directing the telescope’s light to scientific instruments with extreme precision. More here ➡️ tmt.org/news/705

🌟Milestone achieved! TMT’s Wide Field Optical Spectrograph (#WFOS) passed its first Preliminary Design Review. WFOS will study nearly 100 galaxies or stars at once, unlocking new insights into the intergalactic medium ✨ 🔗 tmt.org/news/707

TMTの新たなサイエンスケース創出を目指す「TMT-ACCESS」第3回ワークショップが7月に開催されました。装置開発の課題とブレークスルーをテーマに、講演・討論・ラボツアーを実施。総勢43名の大学院生、若手研究者、スタッフが集まり、TMTの次世代装置の計画を議論しました。tmt.nao.ac.jp/blog/1950

🌟Another milestone for TMT Instrumentation: MODHIS has passed its Conceptual Design Review!🌟 This advanced near-infrared spectrograph will deliver ultra-high-resolution spectra with TMT’s adaptive optics. A key strength is the collaboration between TMT and W. M. Keck Observatory,
