Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 ...

Astronomers produce the most complete map of the center of the Milky Way, which can provide insight into how stars and planets are formed.

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...

Launched to Mars in November, NASA’s ESCAPADE probes — operated by UC Berkeley’s Space Sciences Lab — are now testing their instruments in a never-before-visited region of Earth's magnetic field.
