Rosetta researchers think comets are less likely to be the source of Earth's water than previously thought, which also makes them a great source of fuel for fictional starship warp cores.
In an out of this world first, the space probe enters the gravitational pull of a comet ahead of a landing attempt scheduled for November.
In 2014, humanity tagged a comet and became better acquainted with Mars and our place in the universe. Take a tour through the year in space.
A color image of Rosetta's comet buddy has emerged online and may shine some brightness on a comet that has become famous in black and white.
It's one of the most historic thuds heard in recent years. At only two seconds long, it offers a lot more data for scientists to unpack than you might think.
Rosetta spent more than a decade traveling from Earth to hop a ride on a comet for the first time in history. Here's a look back at one long cosmic road trip.
Space history is rarely made without some hiccups. Rosetta's lander, Philae, successfully reached its new comet home, but it's now in a precarious operating position.
The hunt for Rosetta's lost lander Philae is gaining steam as scientists pore over images from above the comet that may help reveal its final location.
