Cambridge, MA — A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is ...

Scientists now estimate that there are over a trillion galaxies in the Universe. Many follow broad classification patterns, but no two are exactly alike. The variety of galaxies we see gives us a ...

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 ...

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 ...

Using the Event Horizon Telescope (EHT), astronomers have achieved very-long-baseline interferometry test observations at 345 GHz, the highest-resolution such observations ever obtained from the ...

An image from the ROMULUS computer simulation showing an intermediate mass galaxy, its bright central region with its supermassive black hole, and the locations (and velocities) of "wandering" ...

A few years ago, astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun ...

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 ...

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, 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+, ...
