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 ...

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 ...

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 | ...

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 ...

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 ...

The star Betelgeuse became visibly darker in 2019 and 2020, puzzling astronomers. New images show that the star was partially concealed by a cloud of dust, solving the mystery of the "Great Dimming" ...

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 ...

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 - ...

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.

CfA astronomers led two new EHT studies that have produced the first polarized light image of the supermassive black hole at the heart of the Milky Way Galaxy. Cambridge, MA--A new image from the ...

CfA astronomers helped lead a study discovering changes in the bright ring around M87's black hole, confirming the theoretical understanding of the variable and turbulent flow of material around black ...
