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...

Cambridge, MA - Scientific data taken by the Parker Solar Probe are set to be released to the public on Nov 12. The data files being released contain measurements that were taken closer ...

Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, making them potential collision threats. NEOs also offer clues to the composi...
