Sentences with phrase «ejected dust»

Then in 2010 a new type of active asteroid was discovered, which ejected dust like a shot without an obvious reason.

The team discovered at least four fragments of the object, previously established to have impulsively ejected dust in mid-2011.

The team rules out an asteroid impact because a lot of dust would have been blasted into space all at once, whereas P5 has ejected dust intermittently over a period of at least five months [2].

One explanation for the odd appearance is that the asteroid's rotation rate increased to the point where its surface started flying apart, ejecting dust in episodic eruptions that started last spring.

The team was able to measure the rotational speed of one of these objects, suggesting the asteroid spun so fast it burst, ejecting dust and newly discovered fragments in a trail behind it.

If that happens, it will show that supernovas might not be able to eject dust very far into the universe.

Not exact matches

The images reveal a narrow, well - defined jet of dust ejected by the comet's icy, fragile nucleus.

However, unlike other asteroids, they sometimes have the appearance of comets, when dust or gas is ejected from their surfaces to create a sporadic tail effect.

They showed dust grains being ejected from the surface, arcs that could be traced back, presumably, to geysers of sublimating ice.

One can grab dust ejected from the comet and place it under an on - board microscope to see what it's made of.

One theory suggests that the planemos were violently ejected from a dense collapsing cloud of dust and gas, but that process would almost surely have separated the pair, Jayawardhana says.

The eruption also produced erratic weather and spectacular sunsets throughout the world for many months afterwards, as a result of sunlight reflected from suspended dust particles ejected by the volcano high into Earth's atmosphere.

Eduardo Martin of the Institute of Astrophysics of the Canary Islands believes this is because the puffy planets formed from the gas and dust ejected when two binary stars merged.

[2] The ejected shell formed around AGB stars is composed of gas and dust grains.

Among several scenarios to explain Fomalhaut b's 2,000 - year - long orbit is the hypothesis that an as yet undiscovered planet gravitationally ejected Fomalhaut b from a position closer to the star, and sent it flying into an orbit that extends beyond the dust belt.

At the end of their short lives, the first stars ejected these elements into space, where they gave shape to tiny grains of dust.

If a young star is ejected from the system in which it was born, it would be cut off from the supply of gas and dust it needs to gain more mass, and thus its development would be abruptly halted.

After these molecules are formed on interstellar dust grains, they may be ejected as a diffuse gas.

Two of these visible - light pictures show interstellar gas and dust around young stars at the beginning of their lives, and two more show gas ejected from old stars that are nearing the end of theirs.

Researchers are investigating whether these particles may have formed in classical novae explosions, ejecting stellar material in the form of gas and dust into the space between stars in the galaxy, eventually to be recycled in the creation of our solar system.

Among the material ejected into space by these stars, we find dust, formed by the thermonuclear fusion of lighter elements contained in the stars.

Icy regions on the nucleus are activated as they rotate into sunlight, ejecting large amounts of dust in the jets that are faintly visible in this image.

Stars like our Sun eject large amounts of gas and dust into space, containing various elements and compounds.

Dust trapped in polar ice cores shows that ejected material spread around the globe, indicating that the eruption injected substantial material into the stratosphere, where it can strongly affect climate.

Such proposals often involve sulfates, particles that form in the stratosphere from sulfur dioxide ejected by volcanoes, or other molecules with high reflectivity, such as diamond dust or alumina (aluminum oxide).

The dust they eject is significant and a poorly measured factor.
