Cosmic rays are energetic particles moving at high speeds. Because it takes significant energy to create them, they often serve as cosmic messengers, revealing clues about the extreme environments that produce them — such as supermassive black holes. On Earth, scientists use accelerators to generate and study particles moving at high speeds, but nature needs no such apparatus. Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a possible mechanis ...read more
Hellooo, ladies! This male broad-tailed hummingbird was captured on the upswing of a dramatic dive meant to impress a potential mate. Many male birds put on a flashy show to woo females, and the broad-tailed hummingbird is no exception.
Princeton University researchers Benedict Hogan and Mary Caswell Stoddard have been studying the courtship routines of this tiny Don Juan, published today in the journal Nature Communications.
A male looking to catch a lady hummingbird’s eye will clim ...read more
Last week, Virgin Galactic made history when they launched their SpaceShipTwo suborbital vehicle to space (by one definition) and back with two test pilots on board. This was the first vehicle to launch humans to space from U.S. soil since NASA’s Shuttle program ended in 2011. This was also the first time a commercial craft built to carry paying passengers reached space.
But what’s next for the spaceflight company? Virgin Galactic founder Richard Branson says he plans to be the ...read more
Methane on Mars
There's a methane mystery brewing on Mars.
Scientists first detected traces of methane gas on Mars years ago, and it was exciting because the compound is a sign of life here on Earth. But a European orbiter has yet to find any evidence of methane in the planet's atmosphere, despite being expressly made for the purpose. It's complicating scientists' search for life on the Red Planet.
Traces of methane were first detected in Mars’ atmosphere by the European Space Agenc ...read more
