... in Earth's atmosphere reported that the frequencies of light passing through a depleted ozone layer may not cause the widespread catastrophic damage to plants scientists previously predicted. They found that ... that causes the most damage to alfalfa plants passes straight through the ozone layer, meaning a depleted ozone layer would not increase exposure to the most dam-aging light. Significant depletions in ...

... -- Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell. Researchers saw a large amount of squeezing and ... bulge in solid tides of about 20 inches (50 centimeters). The presence of a subsurface layer of liquid water at Titan is not itself an indicator for life. Scientists think life ... implication for the mystery of methane replenishment on Titan. "The presence of a liquid water layer in Titan is important because we want to understand how methane is stored in Titan ...

... how one could pick out the inversion of the layers. It kind of takes a layered Earth, and it folds it back. So the layers out here gestures are now inverted. And that ... samples of the Earth and bring it way out. Then by looking at the various layers, they have some idea of the likelihood or nonlikelihood, of oil that may be lying ... age of a geological area, a geologist will core way down, and pull out the layers . We built a device to take a core sample of the Moon. I think it ...

... a ground-penetrating radar to study how snow accumulates, adding layer upon layer to the ice sheet over time. Greenland's surface layer vaulted into the news in summer 2012 when higher than ... waves bounce off buried features, informing researchers about the characteristics of the snow and ice layers. From a research station operated by the National Science Foundation called Summit Camp, a spot ...

... stands about 3 miles (5 kilometers) tall, its lower flanks exposing hundreds of rock layers. The rock layers – alternating between lake, river and wind deposits -- bear witness to the repeated filling and ... may have once been a series of lakes." Curiosity currently is investigating the lowest sedimentary layers of Mount Sharp, a section of rock 500 feet (150 meters) high dubbed the Murray ...

... predict what may occur with future climate change. Changes in the properties of the cloud layer caused by aerosols could also have an effect on regional coastal fisheries by altering the ... currents and ocean upwelling. The initially separate cloud and aerosol layers off the Namibian coast are relatively stable. As the cloud layers thicken away from shore like a wedge, it gradually mixes ...

... active systems are used together. 8.6.3.1 Passive Thermal Control Hardware '''''Multi-Layer Insulation.''''' Multi-layer insulation (MLI) is frequently used in spacecraft to minimize the heat exchange of a ... thickness. Mylar or kapton sheets with aluminized surfaces are widely used in this way. Several layers increase the thermal resistance to radiation, generating a very low effective emissivity for the MLI ...

... , the satellite data showed that a "hole" appeared each October in the ozone layer there, meaning the layer in that area became less able to shield the earth from damaging solar ultraviolet ... ultraviolet radiation that became weak when sunspots were fewest. Even under normal conditions the ozone layer was subject to wide variations, so it was difficult to establish that the recent depletion ...

... because of crossed radio signals. The astronauts also studied the seasonal hole in the ozone layer over Antarctica. On November 9, for the third time, Atlantis astronauts aimed solar-energy monitors at the Sun seeking clues about the dwindling ozone layer and global warming. A German satellite released from Atlantis the previous week had produced a ...

... the big solutions. Then it was the next layer, then the next layer, and finally, just before you do the mission, you solved the last layer, and you'd do that, and then ... see if this would work, and if it would, then you could do the next layer. But all these others had to be working along the way. So it was an ...
