Explanation: Bright enough for binocular viewing Comet 21P / Giacobini-Zinner stands out, even in this deep telephoto mosaic of the star cluster and nebula rich constellation Auriga the Charioteer. On the night of September 9 its greenish coma and diffuse tail contrast with the colorful stars and reddish emission nebulae in the almost 10 degree field of view along the Milky Way. The comet was near its perihelion and closest approach to Earth, about 200 light-seconds away. Riding across the distant background just above the comet's tail are well-known Auriga star clusters M38 (left of center) and M36 (toward the right) about 4,000 light-years away. At the top left, emission region IC 405 is only 1,500 light-years distant, more dramatically known as the Flaming Star Nebula. To its right lies IC 410, 12,000 light-years away and famous for its star-forming cosmic tadpoles. A child of our Solar System Giacobini-Zinner is a periodic comet orbiting the Sun once every 6.5 years, and the parent body of October's Draconids meteor shower.

    Erläuterung:Hell genug für binokulare Betrachtung Comet 21P / Giacobini-Zinner zeichnet sich auch in diesem tiefen Telephoto-Mosaik des Sternhaufens und des nebelfleckigen Sternbildes Auriga the Charioteer aus. In der Nacht zum 9. September kontrastieren sein grünliches Koma und sein diffuser Schwanz mit den bunten Sternen und rötlichen Emissionsnebeln im fast 10-Grad-Sichtfeld entlang der Milchstraße. Der Komet befand sich in der Nähe seines Perihels und war ungefähr 200 Lichtsekunden von der Erde entfernt. Über den fernen Hintergrund direkt über dem Kometenschwanz reiten die bekannten Auriga-Sternhaufen M38 (links von der Mitte) und M36 (nach rechts) etwa 4.000 Lichtjahre entfernt. Links oben ist der Emissionsbereich IC 405 nur 1.500 Lichtjahre entfernt, dramatischer als Flaming Star Nebula bekannt. Rechts davon liegt IC 410, 12, 000 Lichtjahre entfernt und berühmt für seine sternbildenden kosmischen Kaulquappen. Ein Kind unseres Sonnensystems Giacobini-Zinner ist ein periodischer Komet, der alle 6,5 Jahre die Sonne umkreist, und die Mutter des Draconiden-Meteorschauers im Oktober.

NASA PhotoNews: Orion in Red and Blue

Image
NASA PhotoNews: Orion in Red and Blue Image Credit & Copyright: David Lindemann Explanation: When did Orion become so flashy? This colorful rendition of part of the constellation of Orion comes from red light emitted by hydrogen and sulfur (SII), and blue-green light emitted by oxygen (OIII). Hues on the featured image were then digitally reassigned to be indicative of their elemental origins -- but also striking to the human eye. The breathtaking composite was painstakingly composed from hundreds of images which took nearly 200 hours to collect. Pictured, Barnard's Loop, across the image bottom, appears to cradle interstellar constructs including the intricate Orion Nebula seen just right of center. The Flame Nebula can also be quickly located, but it takes a careful eye to identify the slight indentation of the dark Horsehead Nebula. As to Orion's flashiness -- a leading explanation for the origin of Barnard's Loop is a supernova blast that occurred about two ...

NASA PhotoNews: Jupiter in Ultraviolet from Hubble

Image
NASA PhotoNews:  Jupiter in Ultraviolet from Hubble Image Credit: NASA, ESA, Hubble; Processing & License: Judy Schmidt Explanation: Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and (not pictured) infrared light. Featured from 2017, Jupiter appears different in near ultraviolet light, partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, are br...

Trapezium: At the Heart of Orion

Image
Trapezium: At the Heart of Orion Image Credit: Data: Hubble Legacy Archive, Processing: Robert Gendler Explanation: Near the center of this sharp cosmic portrait, at the heart of the Orion Nebula, are four hot, massive stars known as the Trapezium. Gathered within a region about 1.5 light-years in radius, they dominate the core of the dense Orion Nebula Star Cluster. Ultraviolet ionizing radiation from the Trapezium stars, mostly from the brightest star Theta-1 Orionis C powers the complex star forming region's entire visible glow. About three million years old, the Orion Nebula Cluster was even more compact in its younger years and a recent dynamical study indicates that runaway stellar collisions at an earlier age may have formed a black hole with more than 100 times the mass of the Sun. The presence of a black hole within the cluster could explain the observed high velocities of the Trapezium stars. The Orion Nebula's distance of some 1,500 light-years would make it t...

NASA PhotoNews: The Great Carina Nebula

Image
NASA PhotoNews: The Great Carina Nebula Image Credit & Copyright: Maicon Germiniani Explanation: A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up reveals remarkable details of the region's central glowing filaments of interstellar gas and obscuring cosmic dust clouds. The field of view is over 50 light-years across. The Carina Nebula is home to young, extremely massive stars, including the stars of open cluster Trumpler 14 (above and left of center) and the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun. Eta Carinae is the brightest star, centered here just below the dusty Keyhole Nebula (NGC 3324). While...

NASA PhotoNews: M100: A Grand Design Spiral Galaxy

Image
NASA PhotoNews: M100: A Grand Design Spiral Galaxy Image Credit: NASA, ESA, Hubble Explanation: Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice's Hair (Coma Berenices). This Hubble Space Telescope image of M100 was taken recently with the Wide Field Camera 3 and accentuates bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe. === #NASA #space #photonews 18.12.25
