Closeup of Solar 'Tadpoles'
…
| Title |
Closeup of Solar 'Tadpoles' with time tags |
| Abstract |
Here is a close-up view of dark 'tentacles' or 'tadpoles' moving towards the solar surface in this solar flare of April 21, 2002 seen by TRACE. One theory proposed in this press release is that they are due to voids created by magnetic reconnection in the flare. This version of the visualization displays the instrument clock time tags. |

McNeil's Nebula
| Title |
McNeil's Nebula |
| Explanation |
It was a clear, cold western Kentucky night [ http://www.wkaa.net/ article.php?articleid=32&cat=NW&ret=index.php ] on January 23rd as seasoned amateur astronomer Jay McNeil tried out his recently acquired 3-inch refracting telescope by imaging the area [ http://wkaa.net/gallery/mcneil/m78Lrgb ] around a familiar object, the M78 reflection nebula [ http://antwrp.gsfc.nasa.gov/apod/ap030121.html ] in Orion. Days later while processing the images, he noted a substantial but totally unfamiliar nebulosity in the region! With a little help from his friends, his amazing discovery [ http://cfa-www.harvard.edu/iauc/08200/08284.html ] is now recognized as a newly visible reflection nebula surrounding a newborn star -- McNeil's Nebula [ http://spacsun.rice.edu/~has/ Articles.html#McNeils%20Nebula ]. Pictured here at the center of this close-up [ http://www.noao.edu/outreach/aop/observers/mcneil.html ], McNeil's Nebula with its illuminating young star [ http://antwrp.gsfc.nasa.gov/apod/ap970619.html ] at the tip, do not appear in images of the area before September 2003. The emergence of McNeil's Nebula [ http://www.rc-astro.com/nebulae/mcneil_anim.htm ] is a rare event to witness and astronomers are eagerly following its development, but Orion will soon lie too close to the Sun in the sky, interrupting further observations for several months. The Orion nebula complex [ http://www.seds.org/messier/more/oricloud.html ] itself is around 1,500 light-years away. At that distance, the above image spans less than 10 light-years. "Update (Feb. 19)": While McNeil's Nebula was not seen on previous images, some dating back to 1951, it is reportedly apparent in an image of the region recorded in the mid-1960s and available on the SEDs [ http://www.seds.org/messier/more/ m078_mcneil.html ] web site. This would indicate that the intriguing reflection nebula and illuminating star are variable, rather than "newly" emerging. |
