On 12 November 2014, the ESA's Rosetta mission landed its Philae probe (thăm dò) on a comet (sao chổi), the first time in history that such a feat (chiến công) has been achieved. Rosetta was launched on 2 March 2004 and travelled 6.4 billion kilometres through the Solar System (Hệ Mặt trời) before arriving at the comet on 6 August 2014.

The landing site, named Agilkia and located on the head of the bizarre (kì lạ) double-lobed object, was chosen just six weeks after arrival based on images and data collected at distances of 30–100 km from the comet. Those first images soon revealed (làm lộ ra) the comet as a world littered (rải rác) with boulders (đá tảng), towering cliffs (vách đá) and daunting precipices (vách đứng) and pits, with jets of gas and dust streaming from the surface.

Over the next 2.5 days, the lander will conduct its primary science mission, assuming that its main battery remains in good health. An extended science phase using the rechargeable secondary battery may be possible, assuming Sun illumination conditions allow and dust settling on the solar panels does not prevent it. This extended phase could last until March 2015, after which conditions inside the lander are expected to be too hot for it to continue operating.

Below you will find a gallery of some of the most amazing images already taken to date by both Rosetta and its lander, Philae; including the first ever image taken from the surface of a comet.
