Example Input: 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. The image -- a panorama of 141 wide-angle pictures -- covers 404,880 miles across Saturn and its ring system.Image is Cassini's first showing Saturn, rings, moons, Earth, Venus and Mars at same timeThe collage is panorama of 141 wide-angle pictures taken July 19Image was possible that day because Saturn obstructed spacecraft's view of sun

Example Input: (CNN) -- The Senate on Thursday passed its version of the health care bill, inching the country closer to the biggest expansion of medical coverage since Medicare was enacted more than four decades ago. Senate Democrats declared victory after the 60-39 party line vote, but one of the most complicated tasks is still ahead. A conference committee must reconcile the differences -- notably a public option, how to pay for the plan that emerges, and coverage for abortion -- and merge them into one. The House and Senate will then have to pass the revised plan before it can be sent to President Obama's desk. Each chamber needs a simple majority vote for final passage.Conference committee must merge House, Senate billsBills differ on public option, abortion language, fundingFinal bill will look a lot like the Senate bill, congressional scholar saysLawmakers might try to extract favors in final negotiations, Ornstein says

Example Input: London (CNN) Unfettered by the concerns of voters, the UK's unelected House of Lords has begun its second day of debate on the "key purpose and principles" of legislation to withdraw from the European Union. A record 191 members of Parliament's upper house have lined up to speak in what is likely to be the largest second reading debate in the chamber's history. No one expects the peers to block the UK's departure from the 27-nation EU, but they could vote at the committee stage to accept amendments to the bill. The legislation would have to go back to the House of Commons if the House of Lords adds amendments, which would delay the bill's passage, endangering Downing Street's March 31 deadline to trigger the Brexit process.Theresa May becomes first Prime Minister to sit in House of Lords for debate in memoryA record 191 members of Parliament's upper house have lined up to speak on Brexit bill
