Instead, the team proposes, soot and other particles in the ships» exhaust create large numbers of cloud droplets that are, on average, smaller than those forming around natural dust particles in the air elsewhere over the ocean.

Variations in the wind speed and the weight of the particles caused some parts of the cloud to travel faster or slower than others, and so the cloud spread as it moved around Earth, until it covered the equator with an almost imperceptible veil of dust and sulfurous particles.

By examining infrared data taken earlier by the Spitzer Space Telescope, they discovered a swath of dust particles ranging in size from 0.1 to 20 microns (finer than a split hair) that added up to the mass of a large asteroid and, based on their warmth, were strewn about 1.8 Earth — sun distances from the star.

Particles in the rings are on average much brighter than Chariklo's surface because they often collide, exposing fresh, bright ice; meanwhile, Chariklo itself continues to accumulate dust, he suggests.

The Hubble images also show the second disc is relatively red, suggesting the dust particles are even smaller than suspected.

Fewer dust particles translates to a warmer - than - usual land surface and cooler - than - usual water.

Careful analysis of the polarisation results revealed these grains of dust to be comparatively large particles, 0.5 micrometres across, which may seem small, but grains of this size are about 50 times larger than the dust normally found in interstellar space.

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.

Researchers found that the size of the dust particles in the inner 22 au gap is smaller than in the other bright regions and guess that a planet similar to Neptune is located in this gap.

Recent research shows that there is high microbial activity on glacial surfaces (Anesio et al., 2009), some associated with pigmented algae, which absorb significantly more light than local inorganic dust particles on the Greenland Ice Sheet (GrIS)(Lutz et al., 2014).

By modifying dust particles in the laboratory to mimic this process, the team was able to measure their cloud - ice - forming potential, discovering some conditions are more favorable than others.

With the help of citizen scientists, the research team has identified seven dust particles and residues - less than 1 millionth of a metre across - that are consistent with interstellar dust, which they have documented in an academic paper entitled «Evidence for interstellar origin of seven dust particles collected by the Stardust spacecraft» and published in the journal Science.

Cosmic dust is small solid particles consisted of silicon, carbon, iron and other elements with the size smaller than 1 micrometer.

The quantity of dust introduced would be far less than the number of particles that exist higher up.

That fact, combined with computer simulations, led the scientists to conclude that the dust particles in the disk are kept within the disk by the gravitational effect of two planets — one closer to the star than the disk and one more distant.

Consequently, particulates in smoke are more of a health concern than the coarser particles that typically make up road dust.

In addition to staining fur, these excess tears also serve as a magnet for dust, dirt, and other particles, leading to a less - than - desirable crust.

Kok's work, which focused on a type of airborne particle called mineral dust, also suggests that there may be several times more dust particles pumped into the atmosphere than previously believed, since shattered dust appears to produce an unexpectedly high number of large fragments.

Of course, particles are generated from sources other than vehicles, including industry, dust, pollens, bushfires and domestic wood fires.

They measure the hydrogen and oxygen isotopes to infer air temperatures at the time the snow fell, and the dust particles give a nice indication of the dusty periods (much of the dust was kicked up far away, in the Gobi Desert, rather than from sources closer to Greenland).

The idea, Lohmann said, is to inject solid particles, like desert dust, into the atmosphere at spots slightly lower than where cirrus clouds would naturally form.
