In the process, they might identify a planet's surface features — such as oceans, continents, ice caps and even cloudbanks — and detect the presence of biomarkers like oxygen, methane and water.

Today the small amount of water detected on the planet is locked in the polar ice caps, but recently discovered geological features suggest liquid water once flowed on its surface.

Last year the Herschel Space Observatory detected wisps of water vapor around the dwarf planet, and since its arrival at Ceres, Dawn has imaged oodles of highly reflective bright spots on the Cereian surface that may be sites of exposed water ice.

With their long strings of light - detecting devices, lowered into deep water or ice to wait for the telltale flashes that signal a neutrino, none of them looks remotely like a conventional telescope.

The Dawn probe has previously detected salts, ammonia - rich clays and water ice on Ceres, which together indicate hydrothermal activity, says study coauthor Carol Raymond, a planetary scientist

Among the findings is strong evidence for the existence of clouds of water or water ice, the first such clouds detected outside of our solar system.

The Shallow Radar experiment will peer 30 feet or more below the Martian surface to detect buried water ice; another instrument, an infrared radiometer, will monitor dust storms and other atmospheric disturbances.

Combe and colleagues used Dawn's visible and infrared mapping spectrometer (VIR) to detect probable water ice at Oxo Crater, a small, bright, sloped depression at mid-latitudes on Ceres.

Davis likens the technique to flying over a frozen river where you can see static patterns formed by the ice while also detecting flowing liquid water — and doing it over and over through the spring as the frozen waterway gradually melts.

In the mid-1990s, a lake containing 1,300 cubic miles of water (as much as Lake Michigan) was detected 12,000 feet below the surface of the ice in East Antarctica, beneath where the Russians had spent years drilling into the ice sheet to study its history.

In 2002, NASA's Odyssey orbiter detected evidence of ice just beneath the surface of the Martian north pole, raising the possibility that during a warm spell liquid water could melt out — a likely requirement for life.

«LCROSS is planned to impact into the moon and see if they can vaporize any water ice and then detect the vapor plume.»

The first major hint came in 2005, when NASA's Cassini spacecraft detected magnetic field distortions along with plumes of water vapor and ice erupting from its south pole.

So far, only water vapour has been detected — unlike the plumes on Enceladus, which also contain ice and dust particles.

We will know even more in late July and August, when the comet begins to warm up near the water - ice line outside of the orbit of Mars, and we can detect the most abundant frozen gas, which is water, as it boils away from the comet.»

The Ralph / Linear Etalon Imaging Spectral Array (LEISA) aboard New Horizons observed Pluto's surface from a range of 108,000 km to show areas where water ice is most abundant as well as possibly detecting areas that are depleted in methane.

Weinberger designed the observations to be able to detect large water ice grains in the surface layer of the disk.

At the time, scientist were able to detect that it was in fact water ice, but little else would be known until the molecular weight of chemicals in the plume could be measured and analysed.

Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes.

Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes (see Figure SPM.6 and Table SPM.1).

All these sensors make measurements at critical frequencies at and above 85 gigahertz (GHz); sensors measure microwave emissions at 183 GHz, the signature frequency band emitted by water vapor, making it feasible to detect frozen hydrometeors (snow, ice, and the like) in the atmosphere.

Conversely, during low solar activity during the Little Ice Age, transport of warm water was reduced by 10 % and Arctic sea ice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibiliIce Age, transport of warm water was reduced by 10 % and Arctic sea ice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibiliice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibility?

In storms, ice and liquid water not only are key ingredients for separating the positive and negative electrical charges that initiate a lightning strike; they also are the main features detected by microwave sensors on satellites.

Warmer water has been detected closer to the edges of Antarctica in recent years, and that can accelerate the melting of ice shelves from below.

The IPCC's Fifth Assessment Report (Summary for Policymakers) states, «Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes.

«Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes,» the report said.

However, detecting acceleration is difficult because of (i) interannual variability in GMSL largely driven by changes in terrestrial water storage (TWS)(7 ⇓ — 9), (ii) decadal variability in TWS (10), thermosteric sea level, and ice sheet mass loss (11) that might masquerade as a long - term acceleration over a 25 - y record, (iii) episodic variability driven by large volcanic eruptions (12), and (iv) errors in the altimeter data, in particular, potential drifts in the instruments over time (13).
