NASA's Future, Pluto's Closeup, Australia's Violent Past
President Obama's plans for the National Aeronautics and Space Administration, unveiled last week, include a push to find new ways of going into space.
In other space news, new images of Pluto taken by the Hubble Space Telescope have revealed that it is a dynamic world that undergoes dramatic atmospheric changes that are seasonal.
Evidence of possible impact craters off the coast of Australia has led a researcher to theorize that pieces of a giant asteroid or comet may have crashed there about 1,500 years ago.
Meanwhile, the Hubble Space Telescope captured the image of two asteroids shortly after they collided head-on between Mars and Jupiter at more than 11,000 miles per hour. At first astronomers mistook the scattered debris for a comet's tail.
And a new ground-based technique to study the atmosphere of a planet outside our solar system was used by a group of astronomers to spot methane gas on an exoplanet. They say the technique could be used by many other earth-bound telescopes.
