Human activity risks contaminating pristine water locked underground for millennia and long thought impervious to pollution, said a study Tuesday that warned of a looming threat to the crucial resource.

Back-to-back volcanic eruptions in the mid-6th century darkened Europe's skies for more than a year and may have ushered in the Dark Ages, according to finding to be presented Friday at a science conference in Vienna.

In a new twist in a landmark exploration, Europe's comet-chasing Rosetta mission has found that its target, 67P/Churyumov-Gerasimenko, has no magnetic field, scientists reported on today.

First classified a planet, then an asteroid and then a "dwarf planet" with some traits of a moon - the more scientists learn about Ceres, the weirder it becomes.
