Rosetta - a mission from the ESA - followed a comet called 67P through Space for a long time. Rosetta got a lot of information, such as temperature measurements, photos, dust grains, measurements of the gravity and the magnetic field of the comet and so on. However, the most remarkable discovery is that she found ingredients that were crucial for the origin of life on Earth.
Rosetta's mission is considered a huge success because it was the first attempt in history to send a lander to a comet.
