The spots are planet - sized regions in which strong magnetic fields become tangled.

Not exact matches

The trick was performed using a strong magnetic field that distorts the movement of electrons in water molecules, which in turn produces a magnetic field opposing the one applied.

Until now, they believed the ions came from Jupiter's magnetosphere, the region in which the planet's magnetic field is strong enough to deflect the «solar wind,» a stream of particles emitted by the sun.

«Most surprising is that the blast wave was still strong enough to cause significant effects in the atmosphere of Saturn, which is nearly a billion miles from the sun and has a magnetic field much larger than Earth's,» says Ed Stone of Caltech, chief scientist of NASA's Voyager program.

At the same time, Juno is busy sampling Jupiter's magnetic field, which is stronger than expected in some places and weaker in others, astronomers announced in the May issue of Science.

«If there is a magnetic field which is very strong, you don't need a piece of glass or a prism to refract the light,» says team member Silvia Zane at University College London.

According to the most prevalent theory, the black hole and the gas disk are surrounded by a strong magnetic field in which particles such as electrons are accelerated to almost the speed of light.

It is probable that strong magnetic fields, which accelerate the particles at right angles to the disk and into the jets, occur here as well.

In 2000, Heyl and Shaviv predicted that the magnetic field of a neutron star — which is 10 trillion times stronger than Earth's — would be strong enough to induce birefringence in the neighborhood of a neutron star.

«These include different types of MRI scans, which use strong magnetic fields and radio waves to produce detailed images of the inside of the brain, and Positron Emission Tomography (PET) scans, which use a small amount of a radioactive drug, or tracer, to test how tissues in the brain are actually functioning.

The breakthrough is in magnetic confinement fusion, in which hydrogen is heated until it is a plasma 10 times hotter than the centre of the sun, and held in place by strong magnetic fields until fusion reactions occur.

The sensitivity of the technique would otherwise only be achieved with a 20,000-fold stronger magnetic field, which would only occur on a neutron star.

This receptor seems to measure the strength of the magnetic field — the field is generally strongest at the poles — and the angle of the field in relation to the ground, which also varies with latitude.

This model describes three types of forces: electromagnetic interactions, which cause all phenomena associated with electric and magnetic fields and the spectrum of electromagnetic radiation; strong interactions, which bind atomic nuclei; and the weak nuclear force, which governs beta decay — a form of natural radioactivity — and hydrogen fusion, the source of the sun's energy.

Earth is protected from a similar fate only by its strong magnetic field, which guides the solar wind around the planet.

Cell - damaging, high - energy particles from interstellar space, which reach the surface because Mars lacks a strong magnetic field

The gauntlet Juno ran at Jupiter held many chances for catastrophe: The spacecraft might have been knocked out by intense magnetic fields (at that distance, 20 times stronger than Earth's), ionizing radiation (a total dose of 265 rads — more than enough to kill a human being), dust particles from Jupiter's rings (from which the main engine was completely unshielded) or loss of power if the solar arrays were unable to reorient to the sun.

In the single - atom qubit used by Morello's team, and which Tosi's new design applies, a silicon chip is covered with a layer of insulating silicon oxide, on top of which rests a pattern of metallic electrodes that operate at temperatures near absolute zero and in the presence of a very strong magnetic field.

The device, known as a transcranial magnetic stimulator, is designed to send a strong electric current through a metal coil, which creates an intense magnetic field for about one millisecond.

But mole rats that built nests within changing magnetic fields showed strong activity in a brain region called the superior colliculus, which collects spatial cues and directs orienting behavior.

«When electrical currents are created in such a system of flows, they can cause a magnetic field which in turn increases the electrical current and so forth — and finally the magnetic field becomes so strong that we can measure it on the surface of Earth,» says Alessandro Toschi.

In the past, there has been a debate regarding whether the jet is mostly made of matter we are familiar with (which is called a «fireball») or strong alternating magnetic and electric magnetic fields (which is called a Poynting - flux - dominated flow).

So more solar activity means a stronger solar magnetic field, which means fewer GCRs reaching Earth, which hypothetically means fewer clouds and more warming.

Superconductors also repel all magnetic fields, which allows them to float in the air when they are placed inside a strong magnetic field.

C. Carreau, ASPERA - 4 & MAG teams, Venus Express, ESA Annotated image illustrating loss of hydrogen through plasma wake Venus may have lost oceans of water due to a runaway greenhouse effect which evaporated water into the upper atmosphere, where ultraviolet light dissociated water into ionized atomic hydrogen and oxygen (some later incorporated into carbon dioxide) that were blown away by the Solar wind due to the lack of a strong magnetic field like the Earth's (more).

A significant feature of these molecular probes are that they stable outside of strong magnetic fields which means they could be easily delivered to the patient in a clinical setting.

The young, eruptive variable star completes a rotation in less than 4.4 days (unlike Sol's 25.4 days or over three and a half weeks) which creates a magnetic field around a hundred times stronger than the Sun's (NASA news release; and Michael E. Contadakis, 1995).
