According to the new data, cometary
bombardment could account for no more than half of Earth's inventory of water, says Francois Robert, a geochemist at the Museum of Natural History in Paris and one of several researchers who brought the paradox of the incompatible ratios to light.
In either case, fine dust appears to be streaming off the rubbly X due to the Sun's radiation pressure, to form the long, cometary
Their detour into cometary
physics was purely accidental, they said.
Deep Impact will be sent on its way toward its new cometary
target on New Year's Eve, when it will swing past the Earth 29,000 km above Mongolia.
346), indicate that certain cometary
ices remain unchanged from their composition in the interstellar cloud that gave birth to the solar system.
Washington, Feb 26 (ANI): New research on comet Wild 2 indicates that inner solar system material was transported to the comet-forming region at least 1.7 million years after the formation of the oldest solar system solids, which is the first constraint on the age of cometary
material from a known comet.
The observed cometary
X-ray emission was much stronger than could be explained by direct reflection of solar X-rays.
In mathematical terms, notes Levison, the cometary
parade proceeds because of the special balance of a quantity that approximates the total energy of a comet and the planet nearest it.
Washington, January 25 (ANI): Scientists at the Southwest Research Institute, US, have determined that differences in the number and speed of cometary
impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states.
Commonly known as van den Bergh 142 (vdB 142), the Elephant's Trunk is a dark cometary
globule on the western edge of IC 1396, the nearly 3[degrees]-wide emission nebula associated with the open star cluster Trumpler 37.
The researchers report in the May 31 Science that they detected it at a high concentration, roughly half that of a more familiar cometary
