It's an inference from the characteristics of this cloud of ice grains that is now being seen by the cameras.

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

A thorough search of interstellar ice grains by infrared astronomers should determine whether radicals indeed play a primary role in constructing prebiotic molecules.

But even cleaner ice may be melting faster due to higher temperatures that cause the formation of larger ice grains, according to the study, published in the European Geosciences Union journal The Cryosphere.

You're getting pummeled by these little ice grains.

Either answer suggests that the rock has been in substantial contact with water, for instance allowing minerals to dissolve, and explaining the salty ice grains we see coming out of the surface.»

Ice worms: The surface of a glacier contains a willy - nilly assemblage of irregularly shaped ice grains joined together by necks of ice.

One week we contemplated images of newly formed star clusters; another week we examined beautiful spectra of ice grains swirling around an infant star.

But the more likely explanation, they think, is that the oxygen was chemically made later — inside ice grains in the disc, where it stayed trapped for eons.

There, the chemicals are being liberated from the surfaces of ice grains where they were forged by light - driven reactions, he notes.

Closer to the star, the chemicals would typically be destroyed by intense radiation, and farther away they'd remain frozen onto ice grains and therefore undetectable.

«Indeed, planets are being mostly formed at a certain distance from the central star where it is cold enough for volatile compounds to condense into solid ice grains.

The observed absorption depth can be explained by the both disk models with / without photodesorption effect within the measurement accuracy, but slightly favors the model with photodesorption effects, implying that the UV photons play an important role on the survival / destruction of ice grains at the Herbig Ae / Be disk surface.

The prominent long - wavelength peak is due to CH3OH - rich ice grains, and is similar to those found in other known massive YSOs.

Urine that it vented also left a residue when tiny particles hit the craft's panels, so Lorenz suggests that future missions to Enceladus could look for signatures of life if similar residue is found in the minuscule dents left on a detector by ice grains from the plumes.

IES provided the first measurements of negatively charged, submicron - sized dust or ice grains in a cometary environment and discovered previously unobserved negative hydrogen ions produced through the solar wind / coma interaction.

In one of the troubling feedback loops of the changing climate, dark ice is partially caused by the warmer Arctic summers climate change has brought us: More warmth means less fresh snowfall to cover areas of accumulated sediment, changes to the shape and size of ice grains that make them less reflective, and more liquid near the surface.

When high - energy ultraviolet light from the central star strikes a clump of dust and ice grains, it drives electrons off the particles.

Another group, led by Frank Postberg of the University of Heidelberg, described finding sodium in the ice grains of Saturn's E ring, which is composed of material released by Enceladian eruptions.

Modeling approaches had assumed that most of the heat generated by the process comes from friction at the boundaries between the ice grains.

A month earlier, astronomers in Germany and the U.K. reported that sodium salts make up as much as 2 percent of the ice grains in the jets.

But mission members changed that policy after they determined that ice grains would not pose a threat to the spacecraft if it made a slow, close approach of the plume's central regions.
