In short, each star's extremely powerful winds of particles are colliding and heating up to roughly 50 million degrees, creating two lopsided «fans» of material that ultimately shape the innards of the dumbbell - like nebula, as this NASA simulation suggests:

«As the gas collides with the lunar surface, the cometary magnetic field becomes amplified and recorded in the small particles when they cool.»

Astronomers believe large moonlets up to at least a half - mile in size may hide among the rings, which themselves are only about 30 feet thick; the taller vertical structures visible here could be ring material that «splashes» up when the fine particles of the rings collide with these moonlets, much as water at the sea's edge can splash up and over a rock.

In a study published in The Astrophysical Journal on June 23, Schnittman describes the results of a computer simulation he developed to follow the orbits of hundreds of millions of dark matter particles, as well as the gamma rays produced when they collide, in the vicinity of a black hole.

By tracking the positions and properties of hundreds of millions of randomly distributed particles as they collide and annihilate each other near a black hole, the new model reveals processes that produce gamma rays with much higher energies, as well as a better likelihood of escape and detection, than ever thought possible.

But when a heavy ion collides with an atom of lead, it dislodges charged particles that can be just as destructive as the original heavy ion.

When a particle (such as a WIMP) collides with the detector, it creates crystal lattice vibrations (phonons) and releases electrons.

To be built on the campus of the University of Rome Tor Vergata on the outskirts of the city, SuperB will accelerate beams of electrons and positrons inside two 1.2 - kilometer - circumference rings and study the decay of particles such as B mesons and tau leptons that are produced when the beams collide.

Will a Higgs boson — the most wanted particle in physics — emerge from the wreckage of two colliding protons as seen in this simulation of an experiment planned for Europe's Large Hadron Collider in 2007?

Planet Earth is constantly on the move, colliding with myriads of dark matter particles as it hurtles through space.

When the charged particles collide with molecules in the atmosphere, they release energy as visible light.

Sometimes, such as during an event called magnetic reconnection where the lines explosively collide, the particles are shot off their trajectories, as if they were fired from a cannon.

But getting more protons to collide is an ongoing challenge because, as one beam of these positively charged particles passes through the other, the particles» like charges make them want to move away from one another.

The basic idea is that, in the case of large nuclei such as gold, which have a very large positive electric charge, electromagnetic interactions play a much more important role in particle production than they do in the case when two small, equally charged protons collide.

Then they tumbled and spun tiny particles of polystyrene, biphenyl, naphthalene and other hydrocarbons inside it, watching as the material collided, charged and clumped under conditions simulating Titan's atmosphere and lower gravity.

Although the exact mechanism that causes these changes remains unknown, the researchers propose that the electrical properties of the air are somehow altered as the incoming charged particles from the solar wind collide with the atmosphere.

For the first time in a metal, scientists have found that the charge - carrying particles in graphene behave as a fluid, where, rather than avoiding each other, particles collide trillions of times a second.

Scattering processes occur when particles collide in accelerators such as the LHC.

As these bouncing particles collide with other particles, they get charged up, eventually having so much electrostatic charge that they stick to other particles and clump.

It has been suggested that gamma rays coming from the dense region of space in the inner Milky Way galaxy could be caused when invisible dark matter particles collide, but two new studies suggest that the gamma ray bursts are due to other astrophysical phenomena such as fast - rotating stars called millisecond pulsars.

Birkeland was convinced that the aurora were created by charged particles streaming from the sun, drawn towards the poles of the earth by the magnetic field surrounding the planet and creating the lights as they collided with atoms in the earth's atmosphere, about 100 kilometers above the surface of the planet.

4 B. Conduction Conduction involves objects in direct contact conduction — the transfer of energy as heat between particles as they collide with one another.
