Sentences with phrase «icy particles in»

Chlorine monoxide, which is produced by a similar series of reactions involving icy particles in the stratosphere, is blamed for the springtime depletion of ozone above Antarctica.

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.»

Not exact matches

One way to study the solar system's formative period is to look for samples of small crystalline particles that were formed at high temperatures but now exist in icy comets.

On September 13 and 14, Cassini took a last look around the Saturn system's greatest hits, taking a color mosaic image of Saturn and the rings, a movie sequence of Enceladus setting behind Saturn, Titan and tiny moonlets in the rings that pull the icy ring particles around themselves to form features called propellers.

The comet is icy, but it contains particles that appear to have formed in a hot zone.

Planets shrouded in clouds full of icy particles, like Venus and Jupiter, for instance, are very reflective.

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.

New measurements indicate that charged particles are raining down from the icy rings, painting dark stripes in Saturn's upper atmosphere.

The temperature of the stratosphere is one of the key factors in the springtime depletion of ozone above the Antarctic where in winter it gets colder than anywhere else on Earth, encouraging icy particles to form in polar stratospheric clouds.

The icy moons that inhabit the main radiation belts continuously absorb energetic particles at their orbits, separating in this way the ionic radiation belts and producing «sweeping corridors» (Kollmann et al. 2013; Kotova et al. 2015).

A paper published this week in Astrophysical Journal, led by Open University academics, has examined the exact structure and behaviour of the icy particles that collide and grow at the onset of planet - formation, in a series of revealing experiments at the UK's world - leading neutron source, ISIS.

Our laboratory experiments show that methyl isocyanate can indeed be produced on icy particles under very cold conditions that are similar to those in interstellar space This implies that this molecule — and thus the basis for peptide bonds — is indeed likely to be present near most new young solar - type stars,» said Niels Ligterink at the Leiden Observatory in the Netherlands.

NASA's Cassini spacecraft discovered hydrogen in the plume of gas and icy particles spraying from Saturn's moon Enceladus.

From the tall mountains and icy lakes, to the particles of snow in the ground and trees, every landscape is so visually stunning and incredibly detailed that you will often find yourself stopping to just observe the environmental beauty around you.
