Unexpectedly, gusts of Martian winds repeatedly acted as cleaning events, wiping the dust away.

The boy's face is covered with a veil, nothing sinister about that: It's there to keep dust away.

One promising strategy: Cover sensitive surfaces with an Electrodynamic Dust Shield — essentially, electrically charged panels that shoot currents through thin wires to zap dust away.

As Surveyor 23 landed in the near-vacuum of the moon, the exhaust gas from its engine should have pushed dust away from the spacecraft.

She turns to dust, and the wind carries the dust away and all through the city; the things she's created go forward with a piece of her attached forever and ever.

Over the last two decades, Pietrasanta's artisan workshops have been resettled just beyond the minuscule center to keep the dust away from residents, but the artist's studios remain there, between the upscale shops and restaurants aimed at the growing number of art-curious tourists.

At this distance the solar wind becomes strong enough to blow the gas and dust away from the coma, enlarging the tail.

Three external explosions and more than 200 rounds of ammunition fired at the bulldozer had no effect on it. For visibility, the bulldozer was fitted with several video cameras linked to two monitors mounted on the vehicle's dashboard. The cameras were protected on the outside by shields of clear bulletproof lexan. Compressed-air nozzles were fitted to blow dust away from the video cameras.

If he saw smaller pieces of gold in the dish, the miner might use his own breath to blow the sand and dust away. The observer found the dry blowing process to be "both tedious and unhealthy." Life on the goldfields was hard, water was scarce, fresh fruit and vegetables were unavailable, and basic commodities, such as flour, were very expensive. Disease, including cholera and typhoid, was common.

Within the story, Stiles says that he chose the name "Toynbee Convector" for his machine, being inspired by "a historian named Toynbee": > ... that fine historian who said any group, any race, any world that did not > run to seize the future and shape it was doomed to dust away to the grave, > in the past. Bradbury almost certainly refers to Arnold J. Toynbee, who proposed that civilisation must respond to a challenge in order to flourish.

The Great Comet of 1811 also had a coma roughly the diameter of the Sun. Even though the coma can become quite large, its size can decrease about the time it crosses the orbit of Mars around from the Sun. At this distance the solar wind becomes strong enough to blow the gas and dust away from the coma, and in doing so enlarging the tail. Ion tails have been observed to extend one astronomical unit (150 million km) or more.

Typical direction of tails during a comet's orbit near the Sun In the outer Solar System, comets remain frozen and inactive and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from observations by the Hubble Space Telescope but these detections have been questioned. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas each form their own distinct tail, pointing in slightly different directions.

In the 1950s, with the increasing popular interest in "electrified" guitars, some manufacturers turned to Rowe Industries rather than expending resources on making their own pickups. As a result, Harry DeArmond is best known for pickups used on inexpensive "beginner" instruments as well as quality guitars. Most widely distributed were the so-called "gold foil" pickups, primarily installed in inexpensive Harmony Company guitars. Generally, these have a chrome-plated metal casing, with cut-out shapes (leading to further colloquial naming: diamond, S, moustache, scroll, and more), beneath which was placed a metalized plastic shim, for aesthetic reasons as well as to simply keep dust away from the pickup's inner parts.

Bandanas became an increasingly utilized tool in the spread of pro war propaganda during the early and mid 20th century when World War 1 and World War 2 were being fought. It was thought that by purchasing and sporting a pro-war paisley bandana, the person was helping to support their country in winning the war. The Paisley bandana started to feature in countless numbers of western movies and thus took on the symbol of the American west. Previous to the 1970s, paisley bandanas were worn by many blue collar and labor workers in an effort to keep dust away from their mouths and noses, the bandana's symbolism once again shifted in American minds, being associated with hard work.

Comet Holmes (17P/Holmes) in 2007 showing blue ion tail on right Animation of a comet's tail A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye.

A comet's orbit showing the different directions of the gas and dust tails as the comet passes the Sun In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from the Hubble Space Telescope observations, but these detections have been questioned, and have not yet been independently confirmed. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous tail to form, which points away from the Sun.
