New high-resolution simulations show one million galaxies forming some 13 billion years ago. Cambridge, MA-- It looks like fireflies flickering in the darkness. Slowly, more and more amass, lighting ...

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 ...

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 ...

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 ...

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 ...

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 ...

The highlight of the new chart is a wake of stars, stirred up by a small galaxy set to collide with the Milky Way. The map could also offer a new test of dark matter theories. Cambridge, MA - ...

Analyzing more than two decades' worth of supernova explosions convincingly bolsters modern cosmological theories and reinvigorates efforts to answer fundamental questions. Cambridge, MA – ...

A new study shows that planets bigger than Earth and smaller than Neptune are common outside the Solar System. These results are another example of how planetary systems can be different from our ...

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, 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 ...
