WATCH: 2017 Solar Eclipse

MIT Wallace Astrophysical Observatory & MIT Haystack Radio Observatory
August 21, 2017

The MIT Wallace Astrophysical Observatory and MIT Haystack Radio Observatory are proud to present the 2017 Solar Eclipse live feed from Westford, MA. Optical feed is of the Sun's chromosphere, in a Hydrogen filter. The 150 foot antenna at Haystack is recording 440Mhz radio data of the ionosphere.




The Wallace Astrophysical Observatory is a teaching and research facility run by the planetary astronomy lab in the Department of Earth, Atmospheric, and Planetary Sciences (EAPS) at the Massachusetts Institute of Technology (MIT). Students in the observing subjects at MIT, 12.409 "Hands-on Astronomy: Observing Stars and Planets" and 12.410 "Observational Techniques of Optical Astronomy", travel to Wallace to make observations.

There are six telescopes mounted on permanent concrete piers at the site. The two largest telescopes at Wallace, the 24-in and the 16-in Cassegrain reflectors, each have their own domes. Four more telescopes are housed in an observing shed with a roll-off roof.


The Haystack Observatory was founded in 1970 and occupies 1,300 acres of hilly woodlands in the towns of Groton, Tyngsborough, and Westford, about 40 miles northwest of the MIT campus in Cambridge, Massachusetts. A group of 100 scientists, engineers and technical personnel conducts the Observatory's research programs and operations. The Observatory is a center within MIT's overall research structure, and the Observatory Director reports to the MIT Vice President for Research.

Haystack Observatory scientists and engineers collaborate with faculty and staff in various departments and laboratories on the MIT campus and at various NEROC institutions, as well as with other national and international groups. Collaborative activities also exist with researchers at the MIT Lincoln Laboratory which shares the facilities at the site in Westford, MA.
