  • NGC1333 9 hours of exposure , taken by Lynn Hilborn, Grafton,Ontario with NP101is@f4.3 and ML8300 camera...October 10 and 12, 2010. (Photo appeared in the December 2010 SkyNews magazine).<br /> NGC 1333<br /> Distance: 720 Light Years<br /> <br /> Right Ascension: 03 : 29.3 (hours : minutes)<br /> Declination: +31 : 25 (degrees : minutes)<br /> <br /> <br /> <br /> Text copyright Robert Gendler<br /> <br /> NGC 1333 is catalogued as a reflection nebula but is actually a diverse region and part of the Perseus OB2 molecular cloud complex. It is one of the nearest star forming regions and particularly rich in young stellar objects (YSOs). Stellar clusters are born embedded within molecular clouds and during their early evolution as YSOs are often only visible at infrared wavelengths, being heavily obscured by dust. Four classes of young stellar objects have been described. Class I though III objects progress through an evolutionary sequence of being less dust enshrouded, as they develop towards the zero-age main sequence. The earliest and most imbedded stage of star formation is the class 0 YSOs. These earliest protostars are difficult to detect due to their heavily imbedded nature. Less than 50 Class 0 objects are known however 4 of these low mass protostars exist in NGC 1333. Also 36 Herbig-Haro obejects have been identified in NGC 1333 confirming its status as a young active region of star formation. Herbig-Haro objects are collisionally excited nebulae produced by outflows ejected by YSOs. They are produced mainly during the first few hundred thousand years of life of a YSO and are usually highly obscured by the cloud core environment from which they formed.<br /> <br /> The gaseous structure of NGC 1333 has been mapped at radio wavelengths and appears to support the large scale star formation observed. Lumpy and filamentary cloud structure exists in NGC 1333 indicative of recent collapse and fragmentation of the parent molecular cloud leading to the clustered mode of star formation observed in the nebula. In addition a series of cavities and shells exist presumably blown out by the outflows of infant protostars. Infrared surveys reveal the presence of YSOs at the edge of these cavities indicating that sequential star formation has occurred there and has been triggered by the effects of the powerful outflows from the first generation of stars. The entire process is extremely recent as the cloud hosting NGC 1333 is less than a million years old.'

Taken by Lynn Hilborn, WhistleStop Obs, Grafton, Ontario, July 30,31 and Aug 1, 2011.<br /> <br /> The Bubble Nebula (NGC 7635) (S162)<br /> Distance: 7800 Light Years<br /> Right Ascension: 23 : 20.7 (hours : minutes)<br /> Declination: +61 : 12 (degrees : minutes)<br /> <br /> Imagine a star 40 times as massive and several hundred thousand times more luminous than our sun? Well, BD +60°2522 is such a star. Its enormous energy output and powerful stellar winds have blown a titanic bubble of ionized gas measuring 6 light years in diameter. Popularly known as the Bubble Nebula, the strange symmetrically round nebula is the outcome of the prodigious energy output and fierce stellar winds of an unusually powerful star known as a Wolf-Rayet star. Named after the French astronomers Charles Wolf and Georges Rayet, who first described the unusual stars in 1867, less than 300 Wolf-Rayet stars (WR) have been identified in our own galaxy and some have even been identified in other galaxies. These extremely powerful stars mark the end stage of rare O type stars that begin their lives with at least 25 times the mass of our sun. Their hot surface temperatures range between 30,000 and 60,000 degrees Kelvin and their stellar winds can exceed 1500 kilometers per second, capable of rapidly depleting the stars outer layers. WR stars can lose two thirds of their mass during this final stage of their stellar life. A star entering the WR stage with 35 solar masses can end up as a 10 solar mass star before it explodes as a supernova.<br /> <br /> Wind blown bubbles, concentric rings and filamentary shaped nebulae are common outcomes of Wolf Rayet driven winds on surrounding gas clouds. The peculiar shape of the Bubble nebula marks the leading edge of the Wolf-Rayet wind front as it plows into the denser stationary material of the interstellar medium. The prodigious winds of this WR star travel at 9 million kilometers per hour. The asymmetry of the bubble in relation to BD +60°2522 is believed due to subtle differences in the density of the surrounding gaseous material. Also the bright arcs and small condensations which characterize the bubble's surface are also related to density variations in the swept up material forming the bubble wall. The prominent inner bright knot projected along the western wall of the bubble is actually the ionized edge of a larger cloud that physically lies outside the bubble itself.<br /> <br /> The Bubble Nebula, NGC 7635 is imbedded in the surrounding HII region Sharpless 162 (S162). The entire complex is located in the Perseus arm of the Milky Way. BD +60°2522 the sole exciting star of the nebula is a type O6.5 giant with a surface temperature of 34,000 degrees. It is considered a member of the Cas OB2 stellar association.<br /> Text with permission of Robert Gendler.
  • vdB 152 in Cepheus. Devouring stars !! 7.5 hours of exposure. TEC 140@f7 and FLI ML8300 camera on Takahashi NJP mount. Lum 1x1 27x10m, RGB each 2x2 12x5m. Taken by Lynn Hilborn, WhistleStop Observatory, Grafton, Ontario on July 6 and 8, 2011.<br /> Described as a "dusty curtain" or "ghostly apparition", mysterious reflection nebula vdB 152 really is very faint. It lies about 1400 light-years away, along the northern Milky Way in the royal constellation Cepheus. Near the edge of a large molecular cloud, pockets of cosmic dust in the region block light from background stars or scatter light from the embedded bright star (top) giving parts of the nebula a characteristic blue color. Ultraviolet light from the star is also thought to cause a dim reddish luminescence in the nebular dust. Though stars do form in molecular clouds, this star seems to have only accidentally wandered into the area, as its measured velocity through interstellar space is very different from the cloud's velocity.

  • M33, the Triangulum Galaxy. The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy (courtesy of APOD)<br /> Taken by Lynn Hilborn, November 2010.
