The double spikes in Leonid activity in 2001 and in 2002 were due to the passage of the comet's dust ejected in 1767 and 1866.

Amalthea is in a close orbit around Jupiter and is within the outer edge of the Amalthea Gossamer Ring, which is formed from dust ejected from its surface.

Amalthea's orbit lies near the outer edge of the Amalthea Gossamer Ring, which is composed of the dust ejected from the satellite.

They studied the dust ejected in 1866 by comet 55P / Tempel-Tuttle in advance of the anticipated Leonid shower return of 1898 and 1899.

Within about 100, 000 years, most of the gas and dust will be ejected.

The gas in the central part can either be accreted or ejected by the growing planets, while the small dust particles are ejected by the radiation pressure of the central star.

The opaque ejected dust cloud has completely engulfed the B-type companion.

The last full-scale eruption of the Yellowstone Supervolcano, the Lava Creek eruption which happened nearly 640, 000 years ago, ejected approximately of rock, dust and volcanic ash into the sky.

Larger obstacles that might be encountered while passing through the target system would be dispersed by an artificially generated cloud of particles, ejected by support vehicles called dust bugs, some 200 km ahead of the vehicle.

These contaminants include lubricant particles ejected by the compressor, dirt particles, small water droplets or aerosols, and even oil vapor and dust particles

The main and halo rings consist of dust ejected from the moons Metis, Adrastea and other unobserved parent bodies as the result of high-velocity impacts.

Generally, these plumes are formed when volatiles like sulfur and sulfur dioxide are ejected skyward from Io's volcanoes at speeds reaching 1 km / s ( 0. 6 mps ), creating umbrella-shaped clouds of gas and dust.

Herbig – Haro objects ( HH ) are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of gas ejected by young stars collide with clouds of gas and dust nearby at speeds of several hundred kilometres per second.

When they approach the Sun, large amounts of gas and dust are ejected by cometary nuclei, due to solar heating.

During the event ( as seen from Earth ) Eta Carinae briefly became the second-brightest star in the sky, after Sirius ; but the ejected gas and dust have since obscured much of its light.

Intergalactic dust is also thought to be ejected from galaxies, and has been observed in intergalactic space.

When the force of the ejected gas at the nozzle is insufficient to accomplish anything useful in terms of dust removal, and the temperature of the can reaches the boiling point of the liquid ( which is for difluoroethane ), the liquid no longer evaporates into gas in any useful quantity.

Stardust is a scientific term ; not just a poetic one, referring to refractory dust grains that condensed from cooling ejected gases from individual presolar stars and mixed into the cloud from which the solar system condensed ..

Those refractory cores are also called Stardust ( section above ), which is a scientific term for the small fraction of cosmic dust that condensed thermally within stellar gases as they were ejected from the stars.

More prominent for interstellar dust grains is sputtering erosion when energetic atoms or ions pierce the surface of a solid to deposit enough energy to cause secondary ions to be ejected from the resulting internal explosion of fast ions.

Then, with a glory that almost wiped out the deep, downward sags in her careworn face, Matilda leaned over the wheel and shouted to Hez, who was stumbling along in the heat and the dust on the opposite side of the wagon `` Pa!!

It was filled with dust and wind and sound and violence.

There was a shattering, cracking sound as the concrete started to buckle, the air filled with dust and flying debris, and everyone in the room -- men and women hit the floor and used the desks as turtlebacks, as ordered.

it was mud in wet weather and dust, ankle-deep, in dry, and could be crossed only at the corner where there were stepping stones.

And now the redcoats were coming, and the gunfire was a part of the dust cloud on the road to the west of us.

In my recollection, there was a long interval between the death of the officer and the appearance of the first of the retreating redcoats, and in that interval the dust cloud over the road seems to hover indefinitely.

It was a Cadillac, black grayed with the dust of the road, its windows closed tight so you knew that the people who climbed out of it would be cool and unwrinkled.

It was all set up so there would be no dust anywhere and so that their children would color in the coloring room, paint in the painting room, play with blocks in the block house, and do all the other things in the proper rooms at exactly the right time.

What bits of Brumidi and Costaggini could be reached at either end seemed in good order, though the roughish sandy surface was thick with dust.

From this earth, then, while it was still virgin God took dust and fashioned the man, the beginning of humanity ''.

If I could put your body in an imaginary atomic press and squeeze you down, squeeze these holes out of you in the way we squeeze the holes out of a sponge, you would get smaller and smaller until finally when the last hole was gone, you would be smaller than the smallest speck of dust that you could see on this piece of paper.

: The neatness of his attire was almost incredible ; I believe a speck of dust would have caused him more pain than a bullet wound.

It is believed that most of the stable beryllium in the universe was originally created in the interstellar medium when cosmic rays induced fission in heavier elements found in interstellar gas and dust.

Dark matter's existence is inferred from gravitational effects on visible matter and gravitational lensing of background radiation, and was originally hypothesized to account for discrepancies between calculations of the mass of galaxies, clusters of galaxies and the entire universe made through dynamical and general relativistic means, and calculations based on the mass of the visible " luminous " matter these objects contain: stars and the gas and dust of the interstellar and intergalactic medium.

However, the current consensus among the scientific community is that the extinction was triggered by the Chicxulub impact event in Central America ( which would have produced a sunlight-blocking dust cloud that killed much of the plant life and reduced global temperature, called an impact winter ).

In December 1960, he suggested the existence of a shell of visible dust particles around the earth some 600 to in space, beyond which there was a layer of smaller particles, a micrometre or less in diameter, extending 2, 000 to.

In the Talmud ( Tractate Sanhedrin 38b ), Adam was initially created as a golem ( גולם ) when his dust was " kneaded into a shapeless husk.

A Polish Kabbalist, writing in about 1630 – 1650, reported the creation of a golem by Rabbi Eliyahu thus: " And I have heard, in a certain and explicit way, from several respectable persons that one man close to our time, whose name is R. Eliyahu, the master of the name, who made a creature out of matter Golem and form tzurah and it performed hard work for him, for a long period, and the name of emet was hanging upon his neck, until he finally removed it for a certain reason, the name from his neck and it turned to dust.

He then removed the Holy Name that was embedded on his forehead, thus causing him to disintegrate and return to dust.

To support his claim that the Great Andromeda Nebula was an external galaxy, Curtis noted the appearance of dark lanes resembling the dust clouds in the Milky Way, as well as the significant Doppler shift.

In 1857 Lamont DuPont solved the main problem when using cheaper sodium nitrate formulations when he patented DuPont " B " Blasting powder ; after manufacturing grains from press-cake in the usual way, the powder was tumbled with graphite dust for 12 hours, forming a coating on each grain which in this case reduced its ability to pick up moisture.

The dust from " repairing " powder in the field was a major hazard.

Such data was used to help determine dust origin and dynamics within the magnetosphere.

The dust was washed in a small stream of water and the heavy gold dust and gold nuggets collected in riffles.
