Cambridge, MA – A new astronomical survey is a portrait of gargantuan proportions. It shows the staggering number of stars bristling among the wispy bands of dust in our home galaxy, the Milky Way.

Cambridge, Mass. – For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star. The stricken world appears destined to spiral closer and ...

Astronomers have discovered what may be a massive star exploding while trying to swallow a black hole, offering an explanation for one of the strangest supernovae ever seen. Cambridge, MA - ...

This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits Neptune completes. Cambridge, MA — A team of astronomers led by the Center for Astrophysics | ...

New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago. Cambridge, Mass. – A new study has ...

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of ...

It is the first dormant stellar-mass black hole to be detected outside of the Milky Way galaxy, the team claims. "For the first time, our team got together to report on a black hole discovery, instead ...

Analyzing more than two decades' worth of supernova explosions convincingly bolsters modern cosmological theories and reinvigorates efforts to answer fundamental questions. Cambridge, MA – ...

An international team of scientists, including multiple astronomers from CfA, have made the first-ever detection of a mid-IR flare from Sgr A*. National Harbor, MD - Using the James Webb Space ...

Until now, astronomers have found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all less than about 3,000 light-years from Earth. Cambridge, MA-- Signs of a ...

For the first time, astronomers used galactic archaeology techniques to trace the chemical "fossil record" of a galaxy outside the Milky Way Cambridge, MA (March 23, 2026) — A team of astronomers led ...

Using new computational algorithms, scientists have measured a sharp ring of light predicted to originate from photons whipping around the back of a supermassive black hole. Cambridge, MA – When ...
