The mysterious bright spot on the dwarf planet Ceres has been revealed in its highest resolution yet, and the bright materials in it appear to be coming from a fractured dome — a possible portal to
icy materials in the subsurface.
The icy materials in 67P will vaporise, emitting gas and dust in a tail that will trail for thousands of kilometres and be observed by Rosetta.
But if a planet like Jupiter were to move too close to the sun, the heat would remove
the icy material in its clouds.
Not exact matches
The other suggests they arose
in a two - stage process called core accretion,
in which bits of
material smashed and fused together to form bigger rocky,
icy bodies.
This
in turn suggests that the planet was bombarded by a lot of
icy material which gathered
in its atmosphere.
Carolyn Porco, leader of the Cassini imaging team, says the ring pictures may even help us figure out how Earth formed: «If we understand how
icy particles
in the outer solar system behave, then we can refine our understanding of how the early solar system formed from that same
material.»
In particular, sensors that could analyze the chemical composition of the plumes, either remotely or by sampling the
material as it whizzed through the vapor, could provide keen insights into the chemical processes taking place on or deep beneath Europa's
icy surface.
What little rocky
material occurs
in today's ring system probably is the debris of collisions between
icy ring particles and asteroids and comets swept up by the planet's huge gravitational field, says Canup.
In contrast to the carbon - rich icy material found in other double star systems, the planetary material identified in the SDSS 1557 system has a high metal content, including silicon and magnesiu

As the permafrost disappears, carbon - rich
material like grass roots, once trapped
in icy soil, sinks to lake bottoms, where bacteria convert it into the greenhouse gas methane.
The vast fountains of
icy material erupting from Enceladus's south pole enthralled planetary scientists when they were first spotted
in images returned by NASA's Cassini spacecraft
in 2005.
Cassini is scheduled to make a close flyby of Enceladus on Oct. 28,
in the mission's deepest - ever dive through the moon's active plume of
icy material.
The presence of
icy grains is expected to assist
in the formation of planets since it creates additional, solid
material to form the planetary core.
(4) Does the «typical» circumstellar disk states of primary star + Kuiper Belt Star show evidence for
material from each of the different kinds of small outer solar system bodies (Comets, Centaurs, KBOs) like the active comet debris
in HR4796A and the
icy KBO debris
in Fomalhaut and HD 32297?
The two researchers racked their brains to come up with
materials that might explain the new spectroscopic feature, and then tested everything from sodium chloride to Drano
in Hand's lab at JPL, where he tries to simulate the environments found on various
icy worlds.
The team found that, at the high pressures expected
in the moon's ocean,
icy materials called clathrates could form that imprison methane molecules within a crystal structure of water ice.
This water even escapes as geysers, through fissures
in its
icy crust, producing stunning plumes that eject
material hundreds of miles high and into Saturn's rings.
If you regularly run on trails or
in very
icy, slushy, or muddy conditions, it's worth checking to see if your favorite shoe comes
in Gore - Tex, the lightweight, waterproof
material found
in all kinds of outdoor gear.
Glazer's success is to lend such sombre, abstract
material a granite conviction, similar
in tone if not thrill to M. Night Shyamalan's work, ably assisted by Kidman's gift for
icy fragility.
Juvenile provocation for provocation's sake, Hard Candy delights
in its stylishly deviant
material —
in which squishy - sounding mutilation and garbage disposal testicle - grinding occurs
in an
icy, claustrophobic apartment characterized by sharp architectural angles and symbolic primary colors — while both pulling its ghastly punches and failing to exhibit the devilish irony of an American Psycho or the meta accusations of a Funny Games.
We expect these kinds of crashes will increase over the holidays, with a combination of
icy winter weather and the tendency of trucking companies to overload their vehicles and overwork their drivers
in an attempt to meet end - of - the - year demands for goods and
materials.
