ESA's spacecraft is following the comet in its orbit around the sun.
Data from the comet can be explained only by life, leading astronomers from Cardiff University have claimed.
ESA announced extension by nine months that will help Rosetta study the comet as it moves away from the Sun.
The lander went blank last November, 60 hours after it was projected onto comet 67P.
Philae went off radar after it landed on the comet last November.
In a scientific first, the European Space Agency has successfully landed a probe on a moving comet.
