A deep survey of more than 200,000 stars in our Milky Way galaxy has unveiled the sometimes petulant behavior of tiny red dwarf stars. These stars, which are smaller than the Sun, can unleash powerful eruptions called flares that may release the energy of more than 100 million atomic bombs.
The "Extreme Planet Makeover" on the NASA/JPL PlanetQuest site lets you roll up your sleeves and create your very own planet.
Balance five factors to create an Earth-like habitable world, or get wild and make your own extreme exoplanet. Use the Image Gallery feature to compare your creation with those of other Earthlings. Once you've finished creating the exoplanet of your dreams, download a picture of your custom world for posterity.
NASA's Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system.
The discovery of this so-called exoplanet is based on more than eight months of data collected by the spacecraft from May 2009 to early January 2010.
"All of Kepler's best capabilities have converged to yield the first solid evidence of a rocky planet orbiting ...
In a study that pushes the limits of observations currently possible from Earth, a team of NASA and European scientists recorded the "fingerprints" of mystery molecules in two distant galaxies, Andromeda and the Triangulum. Astronomers can count on one hand the number of galaxies examined so far for such fingerprints, which are thought to belong to large organic molecules, says the team's leader, Martin Cordiner of the Goddard Center for Astrobiology at NASA's Goddard Space ...
The animals were a big success, filling the oceans for 350 million years before going extinct with the dinosaurs.
Now, exquisite ...
