Kepler, don’t give up on the hunt for exomoons

Feb. 13, 2017 -  
The Kepler spacecraft has been prolific in its search for planets outside our solar system, known as exoplanets, discovering thousands since its launch in 2009. But the hunt for moons orbiting these exoplanets, or exomoons, is vastly more challenging. While no exomoons have been found to date, a...

How this Martian moon became the ‘Death Star’

Oct. 12, 2016 -  
Mars’ largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the enigmatic satellite. The dominant feature on the surface of Phobos (22-...

These space rocks could save the planet

May. 9, 2016 -  
The box was inconspicuous, but Lawrence Livermore National Laboratory (LLNL) postdoctoral researcher Megan Bruck Syal immediately knew its contents: two meteorites around the size of walnuts. They formed about 4.6 billion years ago and survived a history of violent collisions in the asteroid belt...

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

Feb. 16, 2016 -  
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...
