MMT Observatory @mmtobservatory.bsky.social · 29/07/2025The three week long “summer shutdown” at the MMT began last week. We spend the time working on annual preventive maintenance and engineering activities that can’t be done during normal operations. This year, that includes listening to the natural vibrations of the telescope (so we can suppress them) 080

MMT Observatory @mmtobservatory.bsky.social · 08/04/2025Exciting night! The MMT, with the infrared MMIRS instrument, observed Uranus occult a star tonight! It was cool to see the rings and then the planet make the star (mostly) disappear. 🔭 #astronomy 0162

MMT Observatory @mmtobservatory.bsky.social · 16/03/2025We spent today at the #tucsonfestivalofbooks sharing our passion for science and demonstrating how we use masks to take spectra of multiple targets at once. We will be back again tomorrow! 021
MMT Observatory @mmtobservatory.bsky.social · 15/03/2025Weather brings mountains down! A rockslide on Mount Hopkins road on Sunday, March 9th. There was a snowstorm on Friday, March 7th. Some of the snow melted during the day on Saturday and seeped into cracks in the rocks.That water froze on Saturday night and literally broke the rocks apart! 030
