Space experts said the eery ring (pictured) is an artifact caused by the scattering of light inside the camera. Incredible new images of one of Mars' moons rising in the sky have been taken by Nasa's Curiosity rover based on the red planet. The exploration vehicle, which is fitted with a navigation camera, took 86 photos of Phobos rising after sunset on 28 June. They were transformed into a video by Nasa employees back on Earth. While the video is just 32 seconds long, it shows the remarkable moonrise, which actually lasted 27 minutes. Nasa experts at its Jet Propulsion Laboratory said the eery ring seen in the video is an artifact caused by the scattering of light inside the camera. Phobos, the moon seen in the video, measures just 14 miles wide but Mars' only other moon, Deimos is even more diminutive. Many astronomers believe that the two tiny moons are actually old asteroids snared by Mars' gravity millions of years ago. The strange video of the Martian moonrise was shared on the Curiosity Twitter feed in a post that read: 'You asked for the moon. Here it is! See footage from my Navcam of Mars' moon Phobos rising.' Nasa's Curiosity rover landed on Mars last August. It began its two-year tour to explore whether Mars ever supported microbial life, from the enormous Gale Crater. Nasa scientists controlling the robotic vehicle reported in March that a site called Yellowknife Bay could have supported life billions of years ago. Phobos, the moon seen in the video and pictured here, measures just 14 miles wide but Mars' only other moon, Deimos is even more diminutive. Many astronomers believe that the two tiny moons are actually old asteroids snared by Mars' gravity millions of years ago. While the rover has stuck close to its landing site so far, it is now on its way to its final destination, Mount Sharp. The strange mountain towers over the centre of Gales Crater by almost three and a half miles. It is of interest to scientists because its layers of rock can reveal information about the planet's changing environment over time. The video is not the first observation of Phobos made by the Curiosity rover. It took a photograph of the mini moon as it crossed the sun just five weeks after landing on the red planet last year. Nasa released the first official images captured by its Curiosity rover showing the surface of Mars in crystal clear detail last month. The space agency created a panorama made up of one billion pixels stitched together from nearly 900 exposures taken by cameras on-board Curiosity. Just days ago the Curiosity rover shared images of Shaler near the Gale Crater on Mars. It is conducting experiments on the rocks' distinctive layers.

answer: Video of Phobos is made from 86 photos taken in just under half an hour by the Curiosity rover on Mars. The moon pictured measures just 14 miles across and is believed to be an old asteroid. Nasa's Curiosity rover is beginning its mission to climb Mount Sharp.

question: The White House threatened Wednesday to veto a Republican bill to overhaul the widely criticized No Child Left Behind law, calling the effort 'a significant step backwards.' The veto threat came as lawmakers began debate on the measure in the House. A vote is expected on Friday. Republicans say the bill would restore local control in schools and stop top-down education mandates. Democrats say it would allow billions in federal dollars to flow out without ensuring they will improve student learning. The White House threatened Wednesday to veto a Republican bill to overhaul the widely criticized No Child Left Behind law, calling the effort 'a significant step backwards' The bill maintains annual federal testing requirements. It consolidates or eliminates many federal programs, creates a single local grant program and allows public money to follow low-income children to different public schools. It would also prohibit the federal education secretary from demanding changes to state standards or imposing conditions on states in exchange for a waiver around federal law. Democratic Rep. Bobby Scott of Virginia said the bill would allow states to redirect federal funds away from districts with high concentrations of poor students. 'In other words, the low-income areas would get less, the wealthy areas would get more,' Scott said. 'If that's the solution, I wonder what you think the problem was.' The White House said it was opposed to the bill because it 'abdicates the historic federal role in elementary and secondary education of ensuring the educational progress of all of America's students, including students from low-income families, students with disabilities, English learners, and students of color.' Furthermore, the bill 'fails to identify opportunity gaps or remedy inequities in access to the resources,' the White House said. The statement was the latest in a series of veto threats issued by President Barack Obama since both chambers of Congress went under Republican control last month. House Speaker John Boehner of Ohio called the education measure 'a good conservative bill that empowers America and does not empower the bureaucracy here in Washington.' 'If you step back and look at what the president’s doing, the president’s trying to protect the bureaucracy here in Washington,' he said in a statement. 'We’re for an opportunity society and empowering people around America to do their best and to empower them to get the education that’ll help them be successful in life.' At a news conference Wednesday, Boehner called education 'the civil right of the 21st century.' The measure, pushed by Education Committee Chairman John Kline, of Minnesota, would provide states and local communities greater flexibility over how 'federal dollars are used to educate America's kids,' Boehner said. Kline said education can be the 'great equalizer' in America, but only if schools succeed. About 1 in 5 students drops out of high school, and many who do graduate enter college or the workforce with subpar education, Kline said. He decried federal mandates that dictate how to gauge student achievement, define qualified teachers and spend money. 'We need to place less faith in the secretary of education and more faith in parents, teachers and state and local leaders,' he said. Speaker of the House John Boehner accused the president on Wednesday of 'trying to protect the bureaucracy here in Washington.' Republicans, he said, are for empowering people around America to do their best and to empower them to get the education that’ll help them be successful in life' The bipartisan No Child Left Behind law President George W. Bush signed in 2002 sought to close significant gaps in the achievement of historically underserved group of students and their more affluent peers. It mandated annual testing in reading and math for students in grades three to eight and again in high school. Schools had to show student growth or face consequences. No Child Left Behind required that all students be able to read and do math at grade level by 2014. The Obama administration in 2012 began allowing waivers around some of the law's more stringent requirements if schools agreed to certain conditions, like using college- and career-ready standards such as Common Core. House Republican leaders view the bill as a way to show their opposition to the Obama administration's encouragement of the Common Core state standards. The standards have been adopted in more than 40 states and spell out what English and math skills students should master at each level. They have become a political issue in many states because they are viewed by critics as a federal effort even though they were developed by U.S. governors. In the Senate, there appears to be more of a bipartisan effort to fix the law. Republican Sen. Lamar Alexander, the chairman of the Senate Committee on Health, Education, Labor and Pensions, and the committee's senior Democrat, Sen. Patty Murray of Washington, have said they were working together on a proposal. Alexander said this week he wants to get a bill to the full Senate in March.

answer:
President Bush signed the bipartisan No Child Left Behind law in 2002. Republicans say their changes would restore local control in schools and stop top-down education mandates coming from Washington bureaucrats. The new bill maintains annual federal testing requirements. It would allows public money to follow low-income children to different public schools. But according to the White House, it 'fails to identify opportunity gaps or remedy inequities in access to the resources'
