OU researchers excite the Rydberg atom using lasers in a cloud of ground - state atoms, so the Rydberg electron can collide with a ground - state atom and form the molecule.

One puzzle they pondered were the trails of droplets left by electrons as they passed through cloud chambers, an apparatus used to track the movements of charged particles.

They found that in the absence of the cloud, electromagnetic waves accelerated large numbers of electrons to high speed in Earth's inner radiation belt, causing a huge increase in radiation there.

This involves a light particle (photon) exciting the electron cloud of a gold nanoparticle so that it starts oscillating.

The relatively high density of plasma in the cloud prevents the formation of electromagnetic waves that would otherwise accelerate electrons to high speeds, turning them into a form of radiation.

Led by Charles Bennett of Johns Hopkins University, the team accounted for distortions in the microwaves due to collisions with distant clouds of electrons.

Basically, it contains a nucleus, holding some number (call it N) of positively charged protons, which is surrounded by a cloud (N) of negatively charged electrons.

These accelerators work by shooting pulses of intense laser light into plasma to create a wave rippling through the cloud of ionised gas, leaving a wake of electrons akin to those that form behind a speedboat in water.

That's because neutrons interact with the nucleus, rather than the cloud of electrons around it, and interact with very different strengths with the nucleus of each element at the lighter end of the periodic table.

Although northern lights also exist on giant planets such as Jupiter and Saturn, the newly discovered aurorae are thousands of times more powerful; furthermore, the same electrons that trigger these aurorae may drive weather patterns on brown dwarfs, some of which have clouds.

«The electrons that make up the cloud initially bounce off the supermassive black hole at the center of one of the galaxies and accelerate as a result.

Images produced by the Planck satellite have revealed an enormous cloud of electrons traveling near the speed of light in the heart of our Galaxy, the Milky Way.

Describing the clouds of electrons around each atom requires complex quantum calculations that require so - called basis sets.

In a nutshell, this is how you could summarize his theory: The nucleus of an atom is surrounded by a cloud of electrons.

And you could make a movie of this process, reverse it and it would still make sense (like the condensation of a gas cloud, or laser / electron beam inertial confinement fusion).

A third party could then note that this still underestimates what is called the «correlation energy» of the system, because treating the electron cloud as a continuous distribution through when electrons move ignores the fact thatindividual electrons strongly repel and hence do not like to get near one another.

The data collected indicate that the electrons released by the cosmic rays acted as catalysts to accelerate the formation of stable clusters of sulfuric acid and water molecules — the building blocks for clouds.
