[EX Q]: NASA has given the people of Earth a rare treat: A color mosaic that captures not only Saturn, but also the tiny dots of Earth and other planets in the background. The panorama, released Tuesday, was captured by the Cassini spacecraft on July 19, when the sun slipped behind the ringed planet. Earth appears as a bright blue dot to Saturn's lower right, just above Saturn's outer, halo-like E-ring. Venus is a dot to the upper left, with Mars appearing as a faint red dot above and to the left of Venus. This is the first image in which Saturn, its moons and rings, and Earth, Venus and Mars are all visible, NASA said.

[EX Q]: Washington (CNN) Democrats knew a general election battle between Hillary Clinton and Donald Trump would be rough, but many never considered the potential of a nailbiter. During a primary in which Trump usurped the GOP establishment, alienated crucial sectors of the general electorate on issues like immigration and abortion and dinged his own approval ratings, many Democrats salivated at talk of a November duel with the billionaire. Now, as Trump prepares for a general election showdown and a pair of new polls show a statistical dead heat, veteran Democrats warn there is little room for complacency.
