Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material. These AGN emit jets of charged particles that move at speeds close to tha...

Cambridge, MA - As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm. In keeping with the season, astronomers have studied two groups of g...

Astronomers have known for decades that massive outflows of gas are being ejected from galaxies. These fast-moving, bipolar streams act to slow down the rate of star formation and inhibit...

The sun glows with a surface temperature of about 5500 degrees Celsius but its hot outer layer, the corona, has a temperature of over a million degrees. The corona ejects a wind of charge...

Most galaxies are thought to host a supermassive black hole at their nucleus, and dozens have been indirectly measured using techniques ranging from imaging (the most famous recent exampl...

Cambridge, MA - A scientist at the Center for Astrophysics | Harvard & Smithsonian has announced the discovery that mass in triple star systems takes on the characteristics of recipi...

Nearly forty years ago, as he thought about the dramatic new millimeter wavelength observations of gas in star-forming molecular clouds and their newly derived masses and motions, Gary La...

Over two hundred molecules have been discovered in space, some (like Buckminsterfullerene) very complex with carbon atoms. Besides being intrinsically interesting, these molecules radiate...

Paradoxically black holes, which emit no light because of their strong gravitational fields, are regularly discovered via the bright X-ray emission that arises when material accretes onto...

CfA scientist Dr. Alberto Accomazzi has been awarded the Smithsonian Institution's 2019 Secretary Research Prize for "excellence in scholarly websites." The prestigious prize, which has b...
