Sentences with word «cryovolcanism»

If the results hold up, he says, they could increase «the relative role of cryovolcanism in resurfacing icy bodies.»

Active cryovolcanism on Europa?

Weaver holds out hope that Pluto may even remain geologically active, its surface sculpted by cryovolcanism: eruptions powered not by magma, but by melting or boiling ices.

«I suppose cryovolcanism could also bring it to the surface, but impacts would be the safer bet.»

«If we discover something like cryovolcanism on Ceres, that would be spectacular because it would be an indicator that there are subsurface reservoirs of water,» Sykes says.

But he says it's «not ridiculous» to think that Pluto has enough residual heat, from radioactive elements in its rock, to drive cryovolcanism.

«Ongoing cryovolcanism at present seems to be unlikely, because of missing plumes of water and a missing mechanism for creating such powerful activity,» Nathues says.

Desch and Marc Neveu, both at Arizona State University, model cryovolcanism on icy worlds.

Finally, spectroscopic analysis may also reveal evidence of evolutionary processes on KBOs, such cryovolcanism, volatile loss and surface gardening.

A recent paper in the journal Icarus published in 2015 by Marc Neveu of Arizona State University's School of Earth & Space Exploration and his colleagues, states that required atmospheric constituents for cryovolcanism are carbon monoxide, molecular nitrogen, methane and molecular hydrogen.

New evidence for the dwarf planet's icy volcanism, called cryovolcanism, came from NASA's Dawn space probe, which orbits Ceres.

This suggests that both compounds may have come from an interior liquid water layer that erupted to the surface, a process known as cryovolcanism.

There's also a possibility of cryovolcanism, where salty ocean contents actually spray out onto the surface.

Researchers suspect methane could be belched into Titan's atmosphere by cryovolcanism, or volcanoes with water as lava.

If a body has an abundance of at least one of those, which requires (a) that the carbon monoxide does not get dissolved by a body of water, (b) a large amount of accumulated molecular nitrogen or (c) «reduced gases» (like methane) produced in the masses via hydrothermal vents, there may be cryovolcanism on the planet's surface.

Another explanation is cryovolcanism, in which ice and water are forced out of the surface by processes similar to those that drive magma volcanoes on Earth.

«Our pre-flyby prediction, made when we submitted the paper, is that it's most likely that Pluto is actively resupplying nitrogen from its interior to its surface, possibly meaning the presence of ongoing geysers or cryovolcanism,» said Stern.

In addition, optical and radar images of the surface show signs of cryovolcanism — geyserlike eruptions of ammonia - water ice — which also indicates that material wells up from the interior.

Some researchers think that the answer is cryovolcanism, where subsurface layers of mixed ice and minerals percolate slowly to the surface through cracks and fractures, or more swiftly following an impact.

Yet another surprising discovery would be cryovolcanism — volcanic eruptions of gaseous material such as water, ammonia or methane — on Pluto.

The paper also attributes the possibility of cryovolcanism to Pluto's largest moon, Charon.

Because of these extreme changes, astronomers have speculated that the cause may be cryovolcanism.

Gusty winds, clouds, haze, micro snowflakes and even ice volcanoes — cryovolcanism — could all be part of Pluto's dynamic weather system.

It can develop a «parasitic» atmosphere by grabbing some of Pluto's as it escapes; cryovolcanism can cause eruptions that create one; or giant meteor impacts can create one.

Following the Voyager spacecraft encounters with Saturn, cryovolcanism was suggested as a source for the wispy markings on both Rhea and Dione.
