NASA today announced the discovery of 715 planets orbiting 305 stars, revealing multi-planet systems much like our own solar system.
Four of these newly verified planets are in their sun's habitable zone, a distance from a star where the temperature is conducive to the planet's having water in liquid form. With water, it's possible these four planets could potentially hold life.
NASA scientists say the first tests of what could someday become an outer space Internet have far surpassed their expectations.
"It's been beyond what we expected," said Don Cornwell, the Lunar Laser Communications Mission manager at NASA's Goddard Space Flight Center. "We obviously expected it would work well, but this is even better... Everything going better than we thought it would. We're running these systems error free."
Starting last Tuesday, 14 subdomains of NASA went down.
One of them, dedicated to the Kepler mission that searches for habitable exoplanets, had an announcement posted that read, "Down for Maintenance: The requested webpage is down for maintenance. Please try again later."
You've no doubt heard NASA has officially declared that its Voyager 1 spacecraft has left our solar system, becoming the first-ever human-made object to do so. But have you heard the trippy soundtrack Voyager sent back from interstellar space?
An Italian astronaut who nearly drowned during a July 16 spacewalk outside the International Space Station used his blog to describe the terrifying ordeal.
"At this exact moment... I 'feel' that something is wrong," Luca Parmitano, an astronaut with the European Space Agency, wrote in a blog post. "The unexpected sensation of water at the back of my neck surprises me -- and I'm in a place where I'd rather not be surprised."
