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 -- 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 ...

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 ...

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 ...

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 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+, ...

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 ...

Cambridge, Mass. – A team of international experts who are known for debunking black hole discoveries have found a dormant stellar-mass black hole in the Large Magellanic Cloud, a galaxy that ...

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 ...

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 ...
