NASA knows that it can't rely solely on astronomers and robotic rovers to find life on other worlds, so it's recruiting some help. The space agency has formed the Nexus for Exoplanet System Science (NExSS), a coalition of scientists who study astrophysics, Earth, other planets and the Sun. The gro...

Space telescopes are great, but they're hardly the cheapest things to build, launch and maintain, which means scientists are forced to make compromises. The solution to this problem isn't to build a better rocket with a bigger carrying capacity, but to rely upon a low tech way to make any party fa...

NASA's top priority is still taking humans to Mars, and it says private companies who want to do the same don't stand a chance without its support. Administrator Charles Bolden told a US House budget committee, "our ultimate focus is the journey to Mars and everything comes back to that," adding t...

Don't look now, but what you know about the universe's growth might have been turned on its ear. University of Arizona scientists have learned that a certain type of supernova (Ia) isn't the reliable measuring stick for universe expansion that previous data would suggest. By comparing optical and ...

The quest to find proof of life beyond Earth hasn't been without its setbacks, but NASA isn't deterred. If anything, it's optimistic -- Chief Scientist Ellen Stofan now claims that there will be "definitive evidence" of extraterrestrial life within the next 10 to 20 years. Given the sheer number o...

While NASA has been able to go where it wants using existing materials for spacecraft, lightweight ones will enable the agency to explore more places in our solar system and beyond. That's why NASA is now investing in the development of ultra-lightweight (ULW) materials that could reduce a spacecr...

For its crazy 2020 asteroid capture mission and other projects, NASA is developing next-gen "Hall effect thrusters" to corral an asteroid and put it into the moon's orbit. At the same time, the European Space Agency (ESA) is trying to improve its own Hall thrusters to power future missions. If you...
