The Event Horizon Telescope (EHT) Collaboration has conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of ...

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 ...

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 ...

Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner regions of its host (and also with some other properties), ...

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 ...

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 ...

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 ...

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 ...

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 ...

New high-resolution observations clearly show a moon-forming region around exoplanet PDS 70c. The observations have allowed astronomers to determine the ring-shaped region’s size and mass for the ...

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 - ...
