“The Tadpoles and the Flaming Star” - Runaway Stars, Clusters, and Nebulae 

The Flaming Star Nebula - IC405, seen at the bottom - is an emission/reflection nebula that is close to the runnaway star AE Aurigae. AE Aurigae is bulletting through space at an abnormally high velocity relative to its nebula. The effects of its motion can be observed within nebula IC405. This image also contains IC410 - an emission nebula - which can be seen at the top of this image. IC410 is best known for its tadpole like star forming clumps seen in its left side.

Newly Detected Radio Burst Appears to Come from Far Beyond Our Galaxy

The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescopein Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space. Exactly what may be causing such radio bursts represents a major new enigma for astrophysicists. Possibilities include a range of exotic astrophysical objects, such as evaporating black holes, mergers of neutron stars, or flares from magnetars – a type of neutron star with extremely powerful magnetic fields.

The finding by an international team of astronomers marks the first time that a so-called “fast radio burst” has been detected using an instrument other than the Parkes radio telescope in Australia. Scientists using the Parkes Observatory have recorded a handful of such events, but the lack of any similar findings by other facilities had led to speculation that the Australian instrument might have been picking up signals originating from sources on or near Earth.

The Tadpoles of IC 410
Image Credit & Copyright: Martin Pugh

Explanation: This telescopic close-up shows off the otherwise faint emission nebula IC 410 in striking false-colors. It also features two remarkable inhabitants of the cosmic pond of gas and dust below and right of center, the tadpoles of IC 410. The picture is a composite of images taken through narrow band filters. The narrow band image data traces atoms in the nebula, with emission from sulfur atoms in red, hydrogen atoms in green, and oxygen in blue. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars that energizes the glowing gas. Composed of denser cooler gas and dust the tadpoles are around 10 light-years long, potentially sites of ongoing star formation. Sculpted by wind and radiation from the cluster stars, their tails trail away from the cluster’s central region. IC 410 lies some 12,000 light-years away, toward the constellation Auriga.

IC 410

IC 410 is an emission nebula located about 12,000 light years away towards the constellation Auriga. It is about 100 light years across and contains an embedded open star cluster, NGC 1893. This cluster of young stars is responsible for the stellar winds and radiation that shapes and illuminates the nebula.

Visible in this image are two streamers of gas and dust in the upper left. These areas of denser, cooler gas and dust are about 10 light years long. The embedded star cluster is also responsible for these formations, which are potential sites of ongoing star formation.

Located in the constellation of Auriga, the Flaming Star Nebula (IC405, SH2-229 or Caldwell 31) is approximately 1500 light years away.

The Tadpoles (IC410) are located at approximately 12,000 light years, so despite looking like neighbours, these two are not. IC417 and NGC1931 are approximately 10,000 light years from earth.

They are both young star clusters still embedded in glowing hydrogen gas and dust.

IC410 (or the Tadpoles) are located in the constellation of Auriga, approximately 12000 light years away. The Tadpoles are clumps of gas and dust and are likely forming yet new stars within them. The tails of the tadpoles are caused by the radiation pressure and solar wind. The Tadpoles themselves are estimated to be about 10 light years long!

IC410 + Tadpoles

“ In the constellation of Auriga lies fascinating emission nebula IC410. NGC1893 is the young star cluster in the centre which energises the nebula. The 2 ‘tadpoles’ are believed to be filaments of cooler gas and dust, 10 light years long, being blown away from the cluster by the stars’ radiation

The data for this image was gathered over 3 separate nights at the end of November 2011 (yes, I really have been that bad at getting around to processing it!).

Some more SII would have been the ideal really and would have made the colour work a lot easier esp. the outer regions, but anyway here it is.

PS
A Happy 2012 to All !! ”

Aurigae Nebulae

Rich in star clusters and nebulae, the ancient constellation of Auriga, the Charioteer, rides high in northern winter night skies. Composed from narrow and broadband filter data and spanning nearly 8 Full Moons (4 degrees) on the sky, this deep telescopic view recorded in January shows off some of Auriga’s celestial bounty. The field includes emission region IC 405 (top left) about 1,500 light-years distant. Also known as the Flaming Star Nebula, its red, convoluted clouds of glowing hydrogen gas are energized by hot O-type star AE Aurigae. IC 410 (top right) is significantly more distant, some 12,000 light-years away. The star forming region is famous for its embedded young star cluster, NGC 1893, and tadpole-shaped clouds of dust and gas. IC 417 and NGC 1931 at the lower right, the Spider and the Fly, are also young star clusters embedded in natal clouds that lie far beyond IC 405. Star cluster NGC 1907 is near the bottom edge of the frame, just right of center. The crowded field of view looks along the plane of our Milky Way galaxy, near the direction of the galactic anticenter.
