Sentences with phrase «of icy particles»

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.

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

Researchers will soon begin studying data from Cassini's gas analyzer and dust detector instruments, which directly sampled the moon's plume of gas and dust - sized icy particles during the flyby.

«The icy small bodies warm up as they approach the Sun, and the ice sublimes to form a coma [a dense cloud of gas and dust particles around a nucleus] and often a tail, making the comets observable,» she explained.

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.

However, there were other possible sources of water: interplanetary dust particles produced by cometary activity and asteroid collisions, icy rings, or one of the 60 Jovian satellites.

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.»

More startling, Cassini found that Enceladus, just one - tenth the size of Titan, is also active, venting water vapor and a spray of fine icy particles from cracks at its south pole.

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.

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.

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.

Saturn may produce the greatest number of antiprotons because of interactions between cosmic rays — energetic charged particles from space — and the planet's icy rings.

The finding implies the fine spray of water vapor, icy particles and simple organic molecules Cassini has observed coming from fractures near the moon's south pole is being fed by this vast liquid water reservoir.

False color Cassini image illustrating the jets of fine icy particles erupting from the south polar region of Enceladus.

The disk is thought to be made of icy dust particles that have been warmed by the star which, according to Holweger et al (1999), tends to develop after most of the surrounding nebulae of gas has been absorbed or expelled from the developing star.

It also would be far easier to get a water sample from Enceladus, which has plumes of water vapor, ice and particles shooting more than 300 miles off its surface, than from other moons, such as Jupiter's Europa, where a massive ocean is believed to be buried beneath a thick icy crust.

Astronomers found the river of particles was significantly affected by Pluto, but only for short distances from the icy sphere.

For example, Cassini discovered that the Saturn satellite Enceladus is a mini-world of active jets — geyser - like phenomena that blast out water vapor and ice particles from the huge, salty ocean that lies beneath the moon's icy crust.

The scientists traced these particles» origin to Saturn's E-ring, which lies between the orbits of the moons Mimas and Titan and whose icy particles are known to come from Enceladus.

Saturn's icy 246 - mile - wide moon Mimas (near lower left) appears tiny by comparison to the planet's rings, but scientists think the all of the small, icy particles spread over a vast area that comprise the rings are no more than a few times as massive as Mimas.

Even today, they may be spewing ice from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring.

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

Enceladus» southern polar region is also home to occasional jets of water vapor and icy particles (with traces of carbon dioxide and monoxide, volatile gases, and hydrocarbons) that spew from vents within the moon's so - called «tiger stripe fractures,» which create a huge plume of vapor and icy particles that extends into space and affects Saturn's magnetosphere.

Using magic during combat also feels lackluster: unleashing an icy bolt to freeze enemies doesn't feel like you're doing much more than throwing an ice - cube at someone who mildly annoyed you, while setting foes alight with your Nova attack involves you creating what looks like a pile of gellatine at your feet before unleashing the attack which doesn't so much set fire to enemies as generate some weird particle effects.

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.
