Astronomers created detailed imagery of an RV Tauri variable — a rare stellar binary where two stars orbit within a dust disk. Their 130-year dataset spans radio to X-rays, the widest wavelength range yet collected for such a system.

The Milky Way's central molecular zone spans the innermost 1,600 light-years and contains about sixty million solar masses of molecular gas. SMA observations reveal new compact dust core structures within this extreme environment.

ALMA observations of IRS63 — whose disk was first identified by the SMA — reveal planet-forming structures in a system less than 500,000 years old, pushing back the timeline for planet formation.

EHT scientists analyzed data from 2009–2013 showing that the black hole's crescent-shaped shadow has been wobbling and rotating substantially over a decade of observations.

CfA astronomers produced the largest publicly available high-resolution submillimeter spectral line survey of young protostars using the SMA, providing a comprehensive dataset for the star formation community.

The $3 million Breakthrough Prize was shared among 347 scientists for producing the first-ever image of a supermassive black hole. The SMA is a key element of the EHT network.

The Event Horizon Telescope captured an image of M87's supermassive black hole, 55 million light-years away and containing 6.5 billion solar masses. The SMA provided crucial baseline coverage for the observation.

A detailed account of the SMA's role in the 2017 EHT campaign, including the equipment upgrades, site preparation, and observations that contributed to the historic black hole image.

Studies of Sagittarius A* — the closest supermassive black hole — reveal remarkable flaring activity, shedding light on accretion processes near the event horizon.

The Milky Way's central molecular zone contains abundant gas-formation materials yet star-formation activity remains below average. SMA observations reveal the role of high pressures in regulating this process.

Event Horizon Telescope observations reveal the magnetic field structure near Sagittarius A*, providing new insights into the physics of black hole accretion and jet formation.
