A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London's Olympic Stadium – between January 2011 and April ...
Study reveals four new man-made gases in the atmosphere
Scientists at the University of East Anglia have identified four new man-made gases in the atmosphere – all of which are contributing to the destruction of the ozone layer.
Researchers find levels of nitrogen in meteorites similar to levels in Earth's atmosphere
Evidence found for granite on Mars
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth—could have formed there, according to a new study. The findings suggest ...
Early Mars may not have been hospitable after all: study
Instead of a warm, wet and possibly life-bearing planet as some scientists contend, early Mars may have been a hostile and volatile place with frequent volcanic outbursts, a study said Sunday.
Land bulge clue to aviation threat from volcanoes
Bulging in land that occurs before a volcano erupts points to how much ash will be spewed into the sky, providing a useful early warning for aviation, geologists in Iceland said on Sunday.
Cutoff switch may limit spread, duration of oxygen minimum zones
A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that ...

Researchers figure out how oddly shaped sandstone landform structures come about
Remaining Martian atmosphere still dynamic
(Phys.org) —Mars has lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate. Rover team members reported diverse findings today ...
New research technique shows perennial sea ice cover came about earlier than thought
Researchers develop model for identifying habitable zones around star
Researchers searching the galaxy for planets that could pass the litmus test of sustaining water-based life must find whether those planets fall in a habitable zone, where they could be capable of having ...
Black hole, star collisions may illuminate universe's dark side
Scientists looking to capture evidence of dark matter -- the invisible substance thought to constitute much of the universe -- may find a helpful tool in the recent work of researchers from Princeton University ...
