    Explanation: What if we X-rayed an entire spiral galaxy? This was done (again) recently by NASA's Chandra X-ray Observatory for the nearby interacting galaxies known as the Whirlpool (M51). Hundreds of glittering x-ray stars are present in the above Chandra image of the spiral and its neighbor. The image is a conglomerate of X-ray light from Chandra and visible light from the Hubble Space Telescope. The number of luminous x-ray sources, likely neutron star and black hole binary systems within the confines of M51, is unusually high for normal spiral or elliptical galaxies and suggests this cosmic whirlpool has experienced...

  • Astronomy Picture of the Day -- NGC 5195: The Dot Under the Question Mark

    Explanation: Dwarf galaxy NGC 5195 is best known as the smaller companion of spiral M51, the Whirlpool galaxy. Seen together they seem to trace the curve and dot of a cosmic question mark, recorded in Lord Rosse's 19th century drawings as one of the original spiral nebulae. Dwarfed by enormous M51 (aka NGC 5194), NGC 5195 spans about 20,000 light-years. A close encounter with M51 has likely triggered star formation and enhanced that galaxy's prominent spiral arms. Processed from image data available in the Hubble Legacy Archive, this majestic close-up of NGC 5195 makes it clear that the dwarf galaxy...

    Explanation: The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The above image is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope highlighting sharp features normally too red to be seen. Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of the Hunting Dogs (Canes Venatici....

    Explanation: Follow the handle of the Big Dipper away from the dipper's bowl until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (top), NGC 5195. The pair are about 31 million light-years distant and officially lie within the angular...
  • Daring Test For Herschel Telescope: A Glimpse Of Things To Come

    The European Space Agency's Herschel Infrared Telescope opened its 'eyes' on 14 June and the Photoconductor Array Camera and Spectrometer obtained images of M51, ‘the whirlpool galaxy’ for a first test observation. Scientists obtained images in three colours from the observation, which clearly demonstrate the excellence of Herschel, the largest infrared space telescope ever flown.

For starters, Isabel was hundreds of miles across, while M51 (the Whirlpool Galaxy) spans about 50,000 light-years making them vastly dissimilar in scale, not to mention the extremely...

    [Credit & Copyright: Stephane Lamotte Bailey, Marc Deldem, & Jean-Luc Dauvergne] Explanation: One of the brightest supernovas in recent years has just been recorded in the nearby Whirlpool galaxy (M51). Surprisingly, a seemingly similar supernova was recorded in M51 during 2005, following yet another one that occurred in 1994. Three supernovas in 17 years is a lot for single galaxy, and reasons for the supernova surge in M51 are being debated. Pictured above are two images of M51 taken with a small telescope: one taken on May 30 that does not show the supernova, and one taken on June 2...

    Explanation: Where do spiral galaxies keep their supernovae? Near their massive star forming regions, of course, and those regions tend to lie along sweeping blue spiral arms. Because massive stars are very short-lived, they don't have a chance to wander far from their birth place. Remarkably, in the last 6 years two Type II supernovae, representing the death explosions of massive stars, have been detected in nearby spiral M51. Along with a third supernova seen in 1994, that amounts to a supernova bonanza for a single galaxy. As demonstrated in these comparison images, SN2005cs, the supernova discovered in 2005, and...

    M51 Hubble Remix S. Beckwith (STScI), Hubble Heritage Team, (STScI/AURA), ESA, NASA Additional Processing: Robert Gendler Explanation: The 51st entry in Charles Messier's famous catalog is perhaps the original spiral nebula - a large galaxy with a well defined spiral structure also cataloged as NGC 5194. Over 60,000 light-years across, M51's spiral arms and dust lanes clearly sweep in front of its companion galaxy (right), NGC 5195. Image data from the Hubble's Advanced Camera for Surveys has been reprocessed to produce this alternative portrait of the well-known interacting galaxy pair. The processing has further sharpened details and enhanced color...
  • France test-fires new inter-continental missile

    LE BOURGET, France, June 21, 2007 (AFP) - France on Thursday successfully test-fired an inter-continental missile that will be outfitted to its new class of nuclear submarines in 2010, Defence Minister Herve Morin said. The M51 intercontinental missile was fired from the Biscarosse launch site in the Landes region of southwest France and splashed down in the North Atlantic "far from the American coast," said a defence ministry official. "This morning, we carried out the second test of the M51 missile and it was a perfect success," said Morin during a visit to the air and space show at Le...

    M51 Missile Nears First Test Launch; Will Equip Final SSBN in 2010 (Source: defense-aerospace.com; published Sept. 25, 2006) By Giovanni de Briganti; © defense-aerospace.com CHERBOURG and BISCARROSSE, France --- France is nearing completion of the development of the M51 submarine-launched ballistic missile, and is on schedule to carry out the first test launch by year-end. In parallel, assembly of the final hull sections of the fourth and final SNLE-NG missile submarine, Le Terrible, is about three-quarters completed, and it will be floated in 2009 in preparation for sea trials, program officials say. When it enters operational service in July 2010,...
