Latest Comet Hyakutake Stories
Astronomers have been given the clearest view yet of a comet that is supposed to light up the skies later this year.
To study a poorly understood phenomenon known as charge exchange, NASA scientists teamed up to build NASA's first wide-field-of-view soft X-ray camera using "lobster eye" technology.
British scientists have identified a new candidate for the biggest comet measured to date.
Astronomers from the University of California, Los Angeles and the University of Hawaii have discovered multiple fragments ejected during the largest cometary outburst ever witnessed.
NASA's Hubble Space Telescope has probed the bright core of Comet 17P/Holmes, which, to the delight of sky watchers, mysteriously brightened by nearly a millionfold in a 24-hour period beginning Oct. 23, 2007.
When it was launched 17 years ago, scientists and mission engineers for the Ulysses project knew they should expect, well, the unexpected.
Comet McNaught, the Great Comet of 2007, has been delighting those who have seen it with the unaided eye as a spectacular display in the evening sky.
Ten days after part of the Deep Impact spacecraft plunged onto Comet Tempel 1 with the aim to create a crater and expose pristine material from beneath the surface, astronomers are back in the ESO Offices in Santiago, after more than a week of observing at the ESO La Silla Paranal Observatory. In this unprecedented observing campaign - among the most ambitious ever conducted by a single observatory - the astronomers have collected a large amount of invaluable data on this comet.
ESA's XMM-Newton observations of Comet 9P/Tempel 1 revealed that the object is a weak X-ray source. These data were acquired on 4 July 2005 by one of the EPIC X-ray cameras on board the spacecraft during the post-impact observation phase.
Comet Encke -- Because of its proximity to the Sun and its stable orbit, comet Encke is probably one of the most evolved comets that still remains active. It may represent a transition object between an active comet and the defunct comets that are thought to make up a significant percentage of the near-Earth asteroid population. The orbit of comet Encke is very stable both in its size and orientation because it can pass no closer to Jupiter than about 0.9 AU. This orbital stability...
