A cottontail rabbit had scuttled across the road, and a tiny dust cloud
lingered like smoke, marking the way of his flight.
When X-rays encounter grains of dust in interstellar space they can be deflected, and if the dust clouds
are dense they can scatter a noticeable fraction of the X-rays away from their original trajectory, putting them on a triangular path.
By comparing the Chandra data to prior images of dust clouds
detected by the Mopra radio telescope in Australia, the researchers determined that each ring was created by the X-ray reflections off a different dust cloud
on the moons of Jupiter and Saturn have previously been identified, but this is the first time a dust cloud
has been confirmed on the moon.
Minimum Ignition Energy (MIE) for dust clouds
and dust layers
Often, consumers put a plastic bag around their vacuum when emptying it to prevent dust clouds
and spills," said Niklas Melin, the company's product marketing manager.
That may sound like a lot, but remember that these dust clouds
originate front layers on the floor and other surfaces that get lifted up into suspension.
If the test is positive, then the explosive index (Kst) and the maximum pressure rise (Pmax) of the dust should be determined by ASTM E 1226-12a, Standard Test Method for Explosibility of Dust Clouds
PORT TALBOT steel works owners Tata Steel have been issued with an enforcement notice after weeks of complaints from local residents about dust clouds
Summary: The dust clouds
will reappear in the country today, and temperatures are expected to fall as unstable weather conditions continue this weekend.
FORCAST offered astronomers the ability to see the CNR and QC regions and other exotic cosmic features whose light is obscured by water vapor in Earth's atmosphere and interstellar dust clouds
in the mid-plane of the Milky Way.
Scientists are becoming increasingly concerned about dust clouds
as they harmfully pollute the air with particles that lead to breathing and other health problems.
