Cambridge, MA - An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has made the first complete millimeter-wavelength image of the ring o...

Astronomers have produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from radio wave...

Most if not all galaxies are thought to host a supermassive black hole in their nuclei. It grows by accreting mass, and while feeding it is not hidden from our view: it generates X-ray e...

An image of astronomical object, like other images, can be "worth 1000 words." Astronomers therefore use increasingly sophisticated technologies to obtain higher resolution images. At su...

Collisions between galaxies, especially ones rich in molecular gas, can trigger bursts of star formation that heat the dust and result in their shining brightly in the infrared. Astronom...

Cambridge, MA - Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be ha...

On April 10, 2017, the University of Turin in Italy conferred an honorary degree in physics to the CfA's Margaret Geller in a day-long celebration.Margaret J. Geller is a pioneer in mappi...

A globular cluster is a roughly spherical ensemble of stars (as many as several million) that are gravitationally bound together, and typically located in the outer regions of galaxies. L...

Become an astronomer for a day! Hosted as part of the annual Cambridge Science Festival, Cambridge Explores the Universe invites space scientists of all ages to explore the wonder of the ...

Cambridge, MA - The study of alien worlds is entering its next phase as astronomers amass the best planets outside our Solar System to look for signs of life. A newly discovered "super...
