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


question:
Peter Lawwell recently admitted to telling Ronny Deila that it was a matter of getting over the ‘Le Guen hump’ but Celtic’s chief executive might well have cited a couple of names that had met their grim fates closer to home. One thing is for sure: Deila did not need to be an ardent student of the history of Scottish football to appreciate the gravitas of the situation he had become immersed in earlier this season. By late autumn, his side had twice exited Europe while Hamilton Accies had left Celtic Park triumphant. A search party was hardly required to identify his doubters.Celtic boss Ronny Deila was unsure he was cut out for the jobDeila struggled for results initially at Celtic ParkBut the Bhoys now lead the Premiership and should win the title
answer:

Celtic manager _ admitted that the first six months in charge were mentally tough.
