Not exact matches

Most likely, scientists have proposed, the tidal flexing induced in a moon's icy surface causes cracks in polar regions to open widest while the satellite is farthest from its parent planet but clamp shut at other times.

Clementine used radar to detect the signature of water in the permanently - shadowed South polar region, which scientists thought was the most likely place to look for water.

The reason that scientists are looking for life in this area is that it is thought to be the place on Earth that most closely resembles the permafrost found in the northern polar region of Mars at the Phoenix landing site.

Bacteria, however, have remained Earth's most successful form of life — found miles deep below as well as within and on surface rock, within and beneath the oceans and polar ice, floating in the air, and within as well as on Homo sapiens sapiens; and some Arctic thermophiles apparently even have life - cycle hibernation periods of up to a 100 million years while waiting for warmer conditions underneath increasing layers of sea sediments (Lewis Dartnell, New Scientist, September 20, 2010; and Hubert et al, 2010).

Keeling's record of data from Mauna Loa is considered one of the best and most consistent climate records anywhere, though scientists also use other sources for atmospheric data, including samples of air trapped in polar ice, to analyze CO2 levels in past millennia.

«Most of the world's polar bears are likely to disappear in the next 30 to 50 years if the Arctic continues to heat up as climatologists predict, two University of Alberta scientists say.»
