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 — 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 ...

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 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 ...

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 ...

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, 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 ...

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+, ...

The element carbon is a building block for life, both on Earth and potentially elsewhere in the vast reaches of space. There should be a lot of carbon in space, but surprisingly, it's not always easy ...

Cambridge, MA - The missing ingredient for cooking up stars has been spotted for the first time by astronomers. Much like a pressure cooker has a weight on top of its lid to keep the pressure in, ...

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 ...
