What's Up?

The 2022 Spring semester has begun! This semester Dr. Michael Person is instructing 12.409 Hands-On Astronomy: Observing Stars and Planets.  

We also have several exciting projects underway to improve the observatory and expand our offerings.  One of which is to refurbish and automate the Wallace 20' dome.  Another is to replace Pier 1's manual mount with a robotic one, making the telescope more accesible to our students.   

 Tour scheduling has resumed!
