APOD: The Spider and The Fly (2018 Jan 29)

Postby APOD Robot » Mon Jan 29, 2018 5:08 am

Image The Spider and The Fly

Explanation: Will the spider ever catch the fly? Not if both are large emission nebulas toward the constellation of the Charioteer (Auriga). The spider-shaped gas cloud on the left is actually an emission nebula labelled IC 417, while the smaller fly-shaped cloud on the right is dubbed NGC 1931 and is both an emission nebula and a reflection nebula. About 10,000 light-years distant, both nebulas harbor young, open star clusters. For scale, the more compact NGC 1931 (Fly) is about 10 light-years across.

Nice shot revealing some interesting features: the "smoke trail" extending out from the right side of the spider, the two bright yellow-orange stars in the spider's upper left, and what has the appearance of a shock wave moving into the Fly Nebula. Regrettably I couldn't get the enlargement to be any larger than the original photo. Tracking through the links I could find no further details.

Click on the photographer's name under the title and it takes you to his site, and then ultimately to today's APOD, with photo details...

Very nice image... "Come into my parlor...."

Probably better than my "Squiggly Line Nebula"....

Thanks, J.S. I hadn't realized that was available through the photographer's name.
