Kepler Planets (IMAGE) NASA/Goddard Space Flight Center Caption The final observing campaign of NASA's Kepler Space Telescope lasted only a month. As the spacecraft began to run low on attitude control fuel, it couldn’t maintain its position long enough to collect useful observations. In the end, astronomers only had about seven days of high-quality data. A research team worked with a group of citizen scientists and professional astronomers and found three planets in the last bit of data. Credit NASA/JPL-Caltech (K.
