The top prize in high-energy astrophysics has been awarded to Dr. Sheperd Doeleman of the Center for Astrophysics | Harvard & Smithsonian and the Event Horizon Telescope team for the ...

A Cepheid variable star is one whose particular mass and age (along with some of its other physical parameters) result in brightness oscillations with a precise period proportional to the...

The Dark Energy Survey (DES) program uses the patterns of cosmic structure as seen in the spatial distribution of hundreds of millions of galaxies to reveal the nature of "dark energy," t...

Cambridge, MA - NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be...

The interiors of stars are largely mysterious regions because they are so difficult to observe. Our lack of understanding about the physical processes there, like rotation and the mixing ...

This is the body of my workspace.

For the first time, the Center for Astrophysics | Harvard & Smithsonian will host a "Street" at a conference. The 235th meeting of the American Astronomical Society being held this we...

Galaxies that are very luminous in the infrared are generally active in making new stars whose ultraviolet radiation heats the dust. The energy, re-radiated by the dust at infrared wavele...

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...
