Comet Siding Spring Won't Disrupt Martian Orbiters As It Makes Close Approach Of The Red Planet
2014-06-20 07:06:18

April Flowers for redOrbit.com - Your Universe Online Later this year, comet Siding Spring will have a very close brush with Mars. That brush will be so close, in fact, that it lead scientists to worry about the safety of the three spacecraft currently orbiting the planet. Some experts from the University of Maryland (UMD) have used a satellite mounted telescope to observe the "fresh" comet, however, and they find that it poses minimal danger to the Martian spacecraft. Instead, the...

Rosetta at Comet
2014-06-10 16:21:28

NASA Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objective is to arrive at comet 67P/Churyumov-Gerasimenko in August to study the celestial...

ESA's Rosetta Spacecraft Spies Comet Beginning To Form Its Tail
2014-05-16 11:42:34

Brett Smith for redOrbit.com - Your Universe Online The comet targeted for research by the European Space Agency’s Rosetta probe has begun to develop its tail as it zooms closer and closer to the Sun. The probe is maneuvering to align with the comet’s orbit this month and is slated to rendezvous with it in August. On Thursday, the ESA released a series of images showing comet 67P/Churyumov–Gerasimenko developing its tail, or coma. Taken between March 27 and May 4, the...

A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet. It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. "Our findings suggest that PET imaging can reveal cognitive processes that aren't...

Mars-Bound Siding Spring Comet Sprouts Multiple Jets

NASA NASA released on Thursday an image of a comet that, on Oct. 19, will pass within 84,000 miles of Mars - less than half the distance between Earth and our moon. The image on the left, captured  March 11 by NASA's Hubble Space Telescope, shows comet C/2013 A1, also called Siding Spring, at a distance of 353 million miles from Earth. Hubble can't see Siding Spring's icy nucleus because of its diminutive size. The nucleus is surrounded by a glowing dust cloud, or COMA, that measures...

Vegetative Patients Recognize Loved ones
2013-12-17 08:29:25

redOrbit Staff & Wire Reports - Your Universe Online Patients in a vegetative state may be able to recognize photographs of their family and friends, according to a new study published this month in the journal PLOS ONE. Although patients in a vegetative state are awake, can breathe on their own, and appear to go in and out of sleep, they do not respond to what is happening around them, and exhibit no signs of conscious awareness. Since communicating with these patients is...

Searching For What Is Left OF Comet ISON
2013-12-05 08:56:07

NASA Just prior to its closest approach to the sun on November 28, Comet ISON went through a major heating event, and likely suffered a major disruption. At this time, scientists are not sure how much of the comet survived intact. We may be seeing emission from rubble and debris in the comet's trail, along its orbit, or we may be seeing the resumption of cometary activity from a sizable nucleus-sized chunk of ISON. Most agree that up to 90 percent of ISON was destroyed, leaving...

Comet ISON Shows Signs Of Life After Close Encounter With Sun
2013-11-29 11:26:44

Lawrence LeBlond for redOrbit.com - Your Universe Online Last night astronomers were putting the final nail in the coffin for Comet ISON, which had been streaking toward its close encounter with the sun for months, culminating with a perihelion (closest approach of the sun) on Thanksgiving Day. Described as the “comet of the century” by some and predicted to just “fizzle out” by others, ISON has been a hot topic since it was first discovered by Russian astronomers on September...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
