PROBLEM: (CNN) -- X-ray data from NASA's MESSENGER probe points to high levels of magnesium and sulfur on the surface of the planet Mercury, suggesting its makeup is far different from that of other planets, scientists say. The unmanned orbiter has been beaming back data from the first planet for a year and a half. Readings from its X-ray spectrometer point to a planet whose northern volcanic plains formed through upwellings of rocks more exotic than those often found on the Earth, the Moon or Mars, said Shoshana Weider, a researcher at the Carnegie Institution of Washington. "Before this MESSENGER mission, a lot of people assumed it was very like the Moon -- it's dark, it's grey," Weider said. But while the Moon's surface formed when light materials floated to the top of an ocean of molten rock, the low level of calcium on Mercury indicates that didn't happen there.NASA probe gives insight into Mercury's formationThe surface has sulfur levels 10 times higher than Earth'sThe MESSENGER orbiter has been circling Mercury since March 2011

SOLUTION: It's about 5% the size of _ and revolves around the sun every 88 days.

PROBLEM: Two men were hauled off a plane and arrested after an easyJet passenger claimed to have a bomb in his luggage at Manchester Airport. The passenger’s ‘stupid comment’ turned out to be a hoax, but police and airport bosses didn’t take any chances as they remain on high alert following last week’s terror attack in Paris.

Passenger Ed Griffiths, from Pentraeth, Anglesey, Wales, told the Daily Post he and his wife, Laura, had just sat down when crew announced over the loudspeaker that everyone would have to disembark.Plane's captain told passengers 'someone made a stupid comment'Incident at Manchester Airport was treated as a 'security alert'No device was found after passengers went through security againFlight EZY1893 left for Marrakech, Morocco three hours behind schedule

SOLUTION: An easyJet spokesman told MailOnline: ‘Easyjet can confirm that police were requested to board flight EZY1893 from Manchester to _ at the request of the captain.

PROBLEM: (CNN) -- Javier Hernandez has had to be patient this season. Robin van Persie's arrival at Manchester United was followed by a glut of goals that justified Alex Ferguson's $38 million investment in the former Arsenal striker. Hernandez also made a big impact two years ago as a relatively little-known signing from Guadalajara, being named player of the season as United won a record 19th league title. But last season was a different story as the Mexico international played a bit-part role and the club's Premier League crown was snatched by crosstown rivals Manchester City. The 24-year-old came into the 2012-13 campaign fresh after Ferguson demanded he miss Mexico's successful Olympic campaign, but he has started only five matches out of 16 in all competitions.Javier Hernandez comes off the bench to inspire Manchester United to victoryMexican scores twice and has another effort deflected in by Aston Villa playerThe 3-2 win puts United four points clear at the top of the Premier LeagueArsenal lose more ground after blowing a two-goal lead for the second time this week
