New research explores asteroid deflection using spacecraft to crash into body at high speeds

Asteroids headed for a collision with the Earth, if found early enough, can be acted upon to prevent the potentially devastating consequences of an impact. One technique to divert an asteroid, called kinetic impact, uses a spacecraft to crash into the body at high speeds.This approach delivers the momentum of the spacecraft, while also providing an additional boost of…

An X-Ray Eye on Universes

Answers to many scientific mysteries lie in realms invisible to the human eye. Clues to some of the most fundamental questions in astronomy, cosmology, and nuclear science lurk in sections of the electromagnetic spectrum outside the small slice of wavelengths one can see.

Lawrence Livermore scientists' discovery of new young planet provides insight into Jupiter

For the first time, Lawrence Livermore scientists, as part of an international team, have discovered the most Jupiter-like planet ever seen in a young star system, lending clues to understanding how planets formed around our sun.Using a new advanced adaptive optics device on the Gemini Planet Imager (GPI) on the Gemini South Telescope in Chile, the team took an image of…

Giant Steps for Adaptive Optics

Livermore teams are now working on an adaptive optics system to transport x-ray beams in a new generation of high-energy research facilities.

Evidence of a Turbulent Beginning

Research from a Livermore-led team suggests our solar system’s birth was chaotic and included input from a nearby supernova explosion early in its evolution.

Averting Impact: Modeling Solutions to Prevent Asteroid Collisions

The story is common in science fiction: A large asteroid is on a collision course with planet Earth, and scientists are working to save the world. In February 2013, the scenario became a little less fictional when a meteor nearly 20 meters in diameter streaked through the sky above Russia.
