The Center for Astrophysics (CfA) provides world-class opportunities for academic training and career development in astrophysics. It is home to the Harvard University Department of Astronomy, which ...

Cambridge, MA--A new image from the Event Horizon Telescope (EHT) collaboration — which includes scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA) — has uncovered strong and ...

Cambridge, MA -- It looks like fireflies flickering in the darkness. Slowly, more and more amass, lighting up the screen in large chunks and clusters. But this is not a video about insects. It's a ...

Cambridge, MA – Astrophysicists have performed a powerful new analysis that places the most precise limits yet on the composition and evolution of the universe. With this analysis, dubbed Pantheon+, ...

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. – A new study has revealed the true shape of the diffuse cloud of stars surrounding the disk of our galaxy. For decades, astronomers thought this cloud of stars — called the stellar ...

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" ...

Cambridge, MA - Astronomers using data from NASA and the ESA (European Space Agency) telescopes have released a new all-sky map of the outermost region of our galaxy. Known as the galactic halo, this ...

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 ...

Cambridge, MA -- Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. This intriguing result, using NASA's Chandra X-ray Observatory, opens up ...

Using fast radio bursts to guide them, CfA astronomers have mapped the distribution of the Universe's ordinary matter in the space between galaxies, and detected the most distant fast radio bursts to ...

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 ...
