A New Chapter for a Historic Observatory
The Haystack 37m Telescope at MIT Haystack Observatory in Westford, Massachusetts, has officially resumed front-line astronomical research following a comprehensive series of system upgrades. On December 8, 2025, scientists successfully used the telescope to observe the supermassive black hole at the center of galaxy Messier 87 (M87) using very long baseline interferometry (VLBI), marking a significant milestone in its renewed scientific career.
The return to research is the result of more than 10 years of work, including support from NSF and private donors.
A Legacy of Discovery
First commissioned in 1964, the telescope boasts a rich history of groundbreaking achievements. It supported NASA's Apollo missions, created radar maps of Venus, tested general relativity, and contributed to the development of VLBI. It has also been instrumental in studying quasars and star-forming regions.
Between 2010 and 2014, the telescope underwent a major upgrade to enhance its millimeter-wavelength capabilities, primarily to serve U.S. government space radar needs.
The Path Back to Science
The journey back to front-line astronomy involved a decade of dedicated effort:
- 2015: Initial support from the National Science Foundation (NSF) modernized data analysis and radio signal processing systems. This led to the first successful engineering VLBI experiments.
- 2019: Additional NSF funding through the Next Generation Event Horizon Telescope program supported further receiver and computing upgrades.
- 2025: Support from MIT's Jarve Seed Fund and projects led by the Smithsonian Astrophysical Observatory removed the final technical limitations, enabling the M87 campaign.
Targeting the M87 Jet
The December 2025 observations specifically targeted M87*'s jet, a powerful stream of plasma extending thousands of light years from the black hole. The Haystack telescope worked in concert with the Very Long Baseline Array and the Greenland Telescope.
"The telescope's sensitivity enables detection of faint emission, aiding the creation of multifrequency movies of the jet," said Paul Tiede, principal investigator of the M87 study.
A Broad Scientific Horizon
The renewed capabilities of the Haystack 37m Telescope open the door for a diverse range of research projects:
- Planetary Defense: Saverio Cambioni and Richard Teague (MIT EAPS) plan to measure asteroid sizes and shapes to aid in planetary defense.
- Astrochemistry: Brett McGuire (MIT Chemistry) plans to search for complex organic molecules in space.
- Star Formation: Jens Kauffmann, principal investigator of the Haystack 37m Telescope Astronomy Program, noted the telescope's use in studying star and planet formation, and its high value for training students.

Looking Ahead
The telescope continues to be a vital asset for research and education. The refurbishment between 2010 and 2014, combined with the recent upgrades, has positioned it for a new era of discovery. However, to sustain its momentum, the Haystack 37m Telescope Astronomy Program is actively seeking further funding.
