    Comet McNaught Over CataloniaCredit & Copyright: Juan Casado (skylook.net) Explanation: This past weekend Comet McNaught peaked at a brightness that surpassed even Venus. Fascinated sky enthusiasts in the Earth's northern hemisphere were treated to an instantly visible comet head and a faint elongated tail near sunrise and sunset. Recent brightness estimates had Comet McNaught brighter than magnitude -5 (minus five) over this past weekend, making it the brightest comet since Comet Ikeya-Seki in 1965, which was recorded at -7 (minus seven). The Great Comet of 2007 reached its brightest as it rounded the Sun well inside the orbit of Mercury....

    Comet McNaught has just made its appearance in the SOHO (SOlar and Heliospheric Observatory) "LASCO-3" field (at about the 11:00 position) -- and it is very bright!! The real-time image is viewable at http://sohowww.nascom.nasa.gov/data/LATEST/current_c3small.mpg. In the next couple of days, the 48-hr MPEGs of the SOHO LASCO-3 field at http://sohowww.nascom.nasa.gov/data/LATEST/current_c3small.mpg should be well worth watching. ~~~~~~ (The above URL is for the small (256 X 256) MPEG.

    Comet McNaught (2006 P1) has brightened rapidly in the last few days. It's now bright, beautiful, and easy to see at dawn and dusk — as long as you're fairly far north, know exactly where to look, and have an unobstructed horizon and perfect conditions. For most observers in the United States, the comet is quite close to the horizon at twilight, where even the slightest wisp of cloud can hide it. The geometry is more favorable for observers in northern Europe and Canada, who report Comet McNaught as an easy naked-eye object. In the Southern Hemisphere the comet is...

    SAN FRANCISCO - Detailed observations from the first comet samples returned to Earth are debunking some of science's long-held beliefs on how the icy, celestial bodies form. Scientists expected the minute grains retrieved from a comet Wild 2 to be made up mostly of interstellar dust — tiny particles that flow through the solar system thought to be from ancient stars that exploded and died. Instead, they found an unusual mix of primordial material as if the solar system had turned itself inside out. Hot particles from the inner solar system migrated out to the cold, outer fringes beyond Pluto...

    What had been a modest comet seen only with binoculars or telescopes flared up this week to become visible to the naked eye [images]. Comet Swan, as it is called, is in the western sky after sunset from the Northern Hemisphere. It remains faint, likely not easy to find under bright city lights but pretty simple to spot from the countryside. It is a "fairly easy naked-eye comet," said Pete Lawrence, who photographed the comet from the UK. "The tail is now showing some interesting features too." UPDATE: Late Thursday, however, Lawrence reported that the comet already may be getting...

However, these minerals are entirely absent from the Wild 2 samples analysed so far... It is not clear how to explain this difference, says Stardust mission leader Donald Brownlee of the University of Washington in Seattle, US. But he says one possibility is that the material on Tempel 1 was chemically modified by ancient collisions --...

    177 P/Barnard (2006 M3) 1. 177 P/Barnard (2006 M3),. is a returning semi-long period (117 year orbit) comet that was originally discovered on June 24th ,1889 by E.E. Barnard with a six-inch refractor from the Lick Observatory in California at mag. 9.5. For all these years it was lost to the world until the LINEAR robotic imager “recovered” it at 17th magnitude as an apparent asteroidal object. This occurred on June 23, almost exactly 117 years later. For a while it carried the designation P/2006 M3 (Barnhard), but it has since been changed to 177P/ Barnard. In addition, in...

    In 1996 in the Egyptian Museum in Cairo, Italian mineralogist Vincenzo de Michele spotted an unusual yellow-green gem in the middle of one of Tutankhamun's necklaces. The jewel was tested and found to be glass, but intriguingly it is older than the earliest Egyptian civilisation. Working with Egyptian geologist Aly Barakat, they traced its origins to unexplained chunks of glass found scattered in the sand in a remote region of the Sahara Desert. But the glass is itself a scientific enigma. How did it get to be there and who or what made it? Thursday's BBC Horizon programme reports an...

    Terrestrial Evidence of a Nuclear Catastrophe in Paleoindian Times by Richard B. Firestone & William Topping The Paleoindian occupation of North America, theoretically the point of entry of the first people to the Americas, is traditionally assumed to have occurred within a short time span beginning at about 12,000 yr B.P. This is inconsistent with much older South American dates of around 32,000 yr B.P.1 and the similarity of the Paleoindian toolkit to Mousterian traditions that disappeared about 30,000 years ago.2. A pattern of unusually young radiocarbon dates in the Northeast has been noted by Bonnichsen and Will.3,4 Our research...

Scientists are just beginning to piece the story together, and it goes right back to the beginning. Mars, like Earth, was formed from dusty and rocky debris left over after the sun was born 4.57 billion years ago. Initially, there were...

    In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon that was determined to plunge the world into eternal darkness. A fitting name, astronomers reasoned, for a menace now hurtling towards Earth from outerspace. Scientists are monitoring the progress of a 390-metre wide asteroid discovered last year that is potentially on a collision course with the planet, and are imploring governments to decide on a strategy for dealing with it.
  • Moses' Comet

    Moses' Comet Moses’ Comet, by Mike Baillie Discovering Archeology, July/August 1999 Moses called down a host of calamities upon Egypt until the pharaoh finally freed the Israelites. Perhaps he had the help of a comet impact coupled with a volcano. A volcano destroyed the island of Santorini in the Aegean Sea (between today's Greece and Turkey) around the middle of the second millennium B.C. Researchers Val LaMarche and Kathy Hirschboeck suggest the volcano might be associated with tree-ring evidence for several years of intense cold beginning in 1627 B.C. Could that form the basis for strange meteorological phenomena recorded in...

    "Before SOHO was launched, 16 sungrazing comets had been discovered by space observatories. Based on that experience, who could have predicted that SOHO would discover more than sixty times that number, and in only nine years? This is truly a remarkable achievement!" said Dr. Chris St. Cyr, Senior Project Scientist for NASA's Living With a Star program at NASA Goddard Space Flight Center in Greenbelt, Md.

    Data from Deep Impact's instruments indicate an immense cloud of fine powdery material was released when the probe slammed into the nucleus of comet Tempel 1 at 6.3 miles per second. The cloud indicated the comet is covered in the powdery stuff. The Deep Impact science team continues to wade through gigabytes of data collected during the July 4 encounter with the 3-mile-wide by 7-mile-long comet. "The major surprise was the opacity of the plume the impactor created and the light it gave off," said Deep Impact Principal Investigator Dr. Michael A'Hearn of the University of Maryland, College Park. "That...

    The arrogantly named "Rods from God" weapons from space weapons of mass destruction "WMD" program (see the second article below) is well underway and has received a substantial boost from the successful trial attack on comet Tempel-1. Capping a series of other recent planetary death weapons tests such as the failed space mirror test conducted by the Planetary Society, the NASA probe "Deep Impact" provided military observers with significant data and analysis concerning the proper design for kinetic energy weapons configured to slam into an Earth ground target, releasing an explosion similar to an atomic weapon but without the radiation....

    MOSCOW (AP) - NASA's mission that sent a space probe smashing into a comet raised more than cosmic dust - it also brought a lawsuit from a Russian astrologer. Marina Bai has sued the U.S. space agency, claiming the Deep Impact probe that punched a crater into the comet Tempel 1 late Sunday "ruins the natural balance of forces in the universe," the newspaper Izvestia reported Tuesday. A Moscow court has postponed hearings on the case until late July, the paper said. The probe's comet crash sent up a cloud of debris that scientists hope to examine to learn how...

    NASA's film of the impact are incredible. One from the impactor and one from the fly-by craft. Look here: http://www.nasa.gov/mov/121530main_its_approach_x4.mov http://www.nasa.gov/mov/121527main_MRI_impact.mov Watch the one from the impactor. Early in the film, the camera seems to aquire a target, as it was probably supposed to do by design. Keep watching frame by frame. You will see two large craters come into clear view at the center section of the frame. As it gets closer, it seems to target a spot just below the upper crater. Just south south west of the craters looks like a frozen lake. It is very much...

    A Russian astrologist who says NASA has altered her horoscope by crashing a spacecraft into a comet is suing the U.S. space agency for damages of $300 million, local media has reported. NASA deliberately crashed its probe, named Deep Impact, into the Tempel 1 comet to unleash a spray of material formed billions of years ago which scientists hope will shed new light on the composition of the solar system. "It is obvious that elements of the comet's orbit, and correspondingly the ephemeris, will change after the explosion, which interferes with my astrology work and distorts my horoscope," Izvestia daily...

    PASADENA, Calif. - It sounded like science fiction — NASA scientists used a space probe to chase down a speeding comet 83 million miles away and slammed it into the frozen ball of dirty ice and debris in a mission to learn how the solar system was formed. The unmanned probe of the Deep Impact mission collided with Tempel 1, a pickle-shaped comet half the size of Manhattan, late Sunday as thousands of people across the country fixed their eyes to the southwestern sky for a glimpse. The impact at 10:52 p.m. PDT was cause for celebration not only to...

    PASADENA, Calif. - A space probe hit its comet target late Sunday in a NASA-directed, Hollywood-style mission that scientists hope will reveal clues to how the solar system formed. It was the first time a spacecraft had ever touched the surface of a comet, igniting brief Independence Day weekend fireworks in space. The successful strike 83 million miles away from Earth occurred at 10:52 p.m. PDT, according to mission control at NASA's Jet Propulsion Laboratory in Pasadena. Scientists on the mission — called Deep Impact, like the movie — erupted in applause and exchanged hugs. "A lot of people said...
