Pictured in an electromagnetic interference test chamber at Houston's Johnson Space Center on June 2, Robonaut 2 is literally speechless, but that doesn't mean he can't communicate.
The robot, whose dexterity approaches human levels, is tweeting up a storm, with help from its handlers—and will continue doing so, in space, this fall. Developed by NASA and GM, "R2" is to report for duty in November aboard the International Space Station. There, the robot, via commands from Houston, is to take on dull or dangerous tasks.
Despite an expected hectic schedule, R2 should still have time to weigh in on everything from Star Trek to, well, Star Wars. "I idolize Data's positronic mind," R2's handlers tweeted August 10, "but C3PO is rockin' the gold!"
Located about 62 million light-years from Earth, the Antennae galaxies are named after their antennae-like "arms" (not pictured), which are produced by tidal forces spawned by the collision, according to HubbleSite.
The ongoing clash began more than a hundred million years ago and has triggered the creation of millions of stars in clouds of dust and gas.
Located about 200,000 light-years from Earth, the galaxy is named after the Portuguese explorer Fernando de Magellan, who observed it on his voyage around the world in 1519, according to the WISE website.
Possibly the biggest glacier collapse in recorded history, the event was captured within hours by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite.
The resulting "ice island" covers a hundred square miles (260 square kilometers) and holds enough water to keep U.S. public tap water flowing for 120 days, according to Andreas Muenchow, a physical ocean scientist and engineer at the University of Delaware.
