2007: Top 10 space stories

Seething activity on the Sun, Martian caves and bizarre black holes were among the most clicked-on subjects of the year.
1. Dazzling new images reveal the 'impossible' on the Sun
Japan's Hinode telescope revealed the restless frothing of the Sun's surface in astonishing detail.
2. Strange Martian feature not a 'bottomless' cave after all
An extremely dark feature on Mars was found to be just a pit – not the entrance to a deep cavern that future astronauts could call home.
3. Could black holes be portals to other universes?
A study suggested that the objects thought to be black holes could instead be wormholes leading to exotic cosmic locales.
4. Mars probe may have spotted lost rover
In 1997, NASA lost contact with its Pathfinder lander and tiny Sojourner rover, but a decade later, the Mars Reconnaissance Orbiter's eagle eyes spied them both.
5. Satellites solve mystery of low gravity over Canada
A satellite pair called GRACE answered a weighty question: why does Canada have such low gravity?
6. Do black holes really exist?
A controversial study suggested that matter may never collapse completely into a black hole, an idea that would solve a troubling quantum paradox.
7. Satellite snaps first images of mysterious glowing clouds
NASA's new AIM satellite took its first data on silvery blue 'noctilucent' clouds, which may be linked to global warming.

Researchers calculated that if our 3D universe is floating in a higher dimensional space, the shape of those extra dimensions might be detectable by Europe's Planck satellite, set to launch in 2008.
10. Atom smasher may give birth to 'Black Saturns'
Physicists said tiny, ringed black holes resembling Saturn might be produced at the Large Hadron Collider, set to open in 2008.
