Click on the picture to see the computer blinking between two pictures taken at different times.  You're looking for an object that appears in one, but not the other. If you look closely at David Lane's images, you should be able to pick out an object that's only in one of them.

Plot from a radio telescope. Greenbank Radio Telescope in West Virginia ran a pulsar search project with schools, teaching students how to recognize unusual signals and to spot human radio interference in the data. ©Mona Evans, "Young Astronomers Reveal the Universe" http://www.bellaonline.com/articles/art18718.asp

Antennas of the Atacama Large Millimeter/submillimeter Array (ALMA), on the Chajnantor Plateau in the Chilean Andes. The Large and Small Magellanic Clouds, two companion galaxies to our own Milky Way galaxy, can be seen as bright smudges in the night sky, in the centre of the photograph.  (Credit: ESO/C.
