Odd Tilts Could Make More Worlds Habitable
Greenbelt MD (SPX) Apr 19, 2014
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute. The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are somewhat far from their stars. And with some water remaining liquid on the surface long-term, such planets could ... read more

Searching for dark energy with neutrons All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest - "Dark Matter" and "Dark Energy" - remains mysterious. A European collaboration ... more		A study in scarlet This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot newborn stars that formed out of the clouds of hydrogen gas. ... more		New Study Outlines 'Water World' Theory of Life's Origins Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transforme ... more
				B3: the vitamin from outer space Vitamin B3, also called nicotinic acid or niacin, is the precursor to nicotinamide adenine dinucleotide (NAD) - vital to metabolism and a key to the development of ancient life. And though its possible B3 developed non-biologically on ancient Earth, scientists say it's likely carbon-rich meteorites peppering the planet millions of years ago offered an extra dose of niacin. ... more		Scientists achieve first direct observations of excitons in motion A quasiparticle called an exciton - responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits - has been understood theoretically for decades. But e ... more
