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 ...

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 ...

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 ...

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 ...
