The hot outer region of the sun's atmosphere, its corona, is threaded by intense magnetic fields that extend upwards from the surface , often forming loops that are twisted and sheared by...

Magnetic fields play an important but poorly understood role in the formation and evolution of stars -- important because magnetic fields stretch around a hot medium like a rubber band an...

Cambridge, MA On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunter’s sword, the Orion Nebula swaddles a cluster of newborn stars called...

There are currently 340 known extra-solar planets (planets orbiting other stars). These planets range from one as small as only 1.7 earth-masses to a few dozen with masses ten to twenty t...

Nearly all galaxies are thought to have massive black holes at their nuclei, containing millions or even billions of solar masses of material. The size, structure, and physical propertie...
