"If you don't spend time thinking about the future...you don't have that future." NASA Planetary Science Director Jim Green challenges us to think big at the Vision 2050 Conference in Washington, D.C.
Comets are some of the most interesting objects in the solar system. Water that filled the ancient oceans of Earth might have been delivered by comets. And there is growing evidence that many comets (as well as some primitive asteroids) contain molecules key to life. NASA has sent space probes to travel hundreds of millions of miles to study these icy interlopers from the outer solar system.
The most sophisticated space science telescope ever constructed – the James Webb Space Telescope (JWST) – is targeted to launch in October 2018. With a primary mirror three times as wide as The Hubble Space Telescope and a special sensitivity to penetrating infrared radiation, Webb will peer into the far reaches of the universe to reveal how the first stars and galaxies formed after the Big Bang.
Earth. A world dominated by water. Trillions of gallons flow freely across the surface of our blue-green planet. While we once thought oceans made our planet unique, we’re now coming to realize that ‘ocean worlds’ are all around us.
NASA invites people around the world to help us celebrate Earth Day 2017 by "adopting" one of 64,000 individual pieces of Earth as seen from space.
