Cambridge, MA - The explosions of stars, known as supernovae, can be so bright they outshine their host galaxies. They take months or years to fade away, and sometimes, the gaseous rem...

The North Star, Polaris, is a Cepheid variable: one whose mass, age and physical conditions generate periodic oscillations with a period proportional to the star's intrinsic luminosity. ...

The Transiting Exoplanet Survey Satellite (TESS), launched on April 18, has as its core mission goal to discover small transiting exoplanets orbiting nearby bright stars, and to do so it ...

The nuclei of most galaxies host supermassive black holes with millions or even billions of solar-masses of material. Material in the vicinity of such black holes can accrete onto a tor...

The determination of accurate stellar ages and masses is essential for astronomy - but notoriously difficult. Various methods have been developed for stars of all types, achieving differe...

Cambridge, MA - Astronomers from Durham University and the Harvard-Smithsonian Center for Astrophysics (CfA) have found evidence that the faintest satellite galaxies orbiting our own M...

Cambridge, MA -

About twenty-five percent of young stars in our galaxy form in clustered environments, and stars in a cluster are often close enough to each other to affect the way they accrete gas and g...

A new paper by Laura Kreidberg from the Harvard-Smithsonian Center for Astrophysics (CfA) reports observations of the ultra-hot Jupiter WASP-103b by NASA's Hubble Space Telescope (HST) an...

Cambridge, MA - When NASA's Parker Solar Probe launches into space from the Kennedy Space Center, it will begin its journey to the Sun, our nearest star. The Parker Solar Probe will tr...
