For the first time, astronomers have discovered seven Earth-size planets orbiting a nearby star — and these new worlds could hold life. NASA and the Belgian-led research team announced the news Wednesday. This cluster of planets is 40 light-years away in the constellation Aquarius. They circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three planets are in the so-called habitable zone, where water and, possibly life, might exist. The others are right on the doorstep.
The United States has debated immigration since the country's founding, and the Statue of Liberty—a potent symbol for immigrants—is often invoked as an argument for why we should usher in those who seek safety and opportunity with open arms. A little-known fact about Lady Liberty adds an intriguing twist to today's debate about refugees from the Muslim world: according to the Smithsonian Institute the statue itself was originally intended to represent a female Egyptian peasant as a Colossus of Rhodes for the Industrial Age. That might be surprising to people more familiar with the statue’s French roots than its Arab ones.
Thirteen seconds before liftoff, a panicked voice on the livestream said, “hold, hold, hold!” And so SpaceX’s Falcon 9 launch on Saturday morning , February 19, 2017 was scrubbed in the final seconds “out of an abundance of caution,” operators said, because of a potential problem in the rocket’s upper stage. “Better to wait a day,” Elon Musk tweeted. The launch was pushed to Sunday morning, and this time went off without a hitch.
The face of a modern human is almost uniquely flat and extraordinarily expressive. But our remarkable faces may not be as "modern" as we think. (A reconstruction of a Neanderthal face is illustrated above). These reconstructed faces look impassive, but a range of emotions are painted onto visitors' faces at the Natural History Museum in London.
