Apr. 26, 2014: It's spring, and all around the northern hemisphere gardeners are planting seeds, tilling soil, and watering crops. Imagine a gardener's surprise, however, if water from the hose, instead of hitting the soil and sinking in, floated up to the sky. Or if the soil itself rose up... Read More

April 25, 2014: NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that  surprisingly is as frosty as Earth's North Pole. Named "WISE J085510.83-071442.5," the brown dwarf... Read More

April 17, 2014: Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting in the "habitable zone" of another star. The planet, named "Kepler-186f" orbits an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky... Read More

April 16, 2014: Earth's poles are separated by four oceans, six continents and more than 12,000 nautical miles. Turns out, that's not so far apart. New data from NASA's AIM spacecraft have revealed "teleconnections" in Earth's atmosphere that stretch all the way from... Read More
