[ Watch the Video: ScienceCasts: Comet ISON Meteor Shower ] Lee Rannals for redOrbit.com — Your Universe Online Astronomers have been given the clearest view yet of a comet that is supposed to light up the skies later this year. Comet ISON is expected to create a spectacular show in the night sky in November, and NASA's Hubble Space Telescope has provided scientists with a great preview, months before its premier debut. Comet ISON is a "dirty snowball," meaning it is a...

April Flowers for redOrbit.com - Your Universe Online To study charge exchange, a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space, three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera. It is rare to have researchers from such diverse disciplines as heliophysics, astrophysics and planetary science teaming up, but that's exactly what happened at...

British scientists have identified a new candidate for the biggest comet measured to date. Dr Geraint Jones of UCL's Mullard Space Science Laboratory will be presenting the results at the RAS National Astronomy Meeting in Glasgow on Tuesday April 13th. Instead of using the length of the tail to measure the scale of the comet, the group has used data from the ESA/NASA Ulysses spacecraft to gauge the size of the region of space disturbed by the comet's presence. Analysis of magnetometer data...

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. Images and animations showing fragments rapidly flying away from the nucleus of comet 17P/Holmes will be presented by Rachel Stevenson at the European Planetary Science Congress in Potsdam, Germany, on Wednesday September 16. Stevenson, together with colleagues Jan Kleyna and David Jewitt, began observing comet...

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. Astronomers used Hubble's powerful resolution to study Comet Holmes' core for clues about how the comet brightened. The orbiting observatory's Wide Field Planetary Camera 2 (WFPC2) monitored the comet for several days, snapping images on Oct. 29, Oct. 31, and Nov. 4. Hubble's crisp...

When it was launched 17 years ago, scientists and mission engineers for the Ulysses project knew they should expect, well, the unexpected. After all, the joint NASA/European Space Agency-managed spacecraft was going where no spacecraft had gone before - above and below the sun's poles. But the surprises the team expected were wholly in the area of solar research - which would make sense, as the primary mission of the Ulysses spacecraft is to characterize the sun and its influence on the space...

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. Pushing ESO's New Technology Telescope to its limits, a team of European astronomers have obtained the first, and possibly unique, detailed observations of this object. Their images show spectacular jets of gas from the comet spiralling several thousands of kilometres into space, while the spectra reveal the presence of sodium in its...

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. The...

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. XMM-Newton observed that Tempel 1 emits X-rays, as suspected from previous observations of comets, but this emission is very weak. It is not certain whether it is possible to obtain spectral data which indicate the mechanisms by which the comet's X-rays...

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...
