This is an especially beautiful photo by Dave Lane. Worth the time to look it up.

NGC 281

Image Credit & Copyright: Eric Coles and Mel Helm

This cosmic cloud cataloged as NGC 281, “playfully called the Pacman Nebula,” exists at about 10,000 light-years away in the constellation Cassiopeia

Its beautiful sculpted columns and dense dust, captured in a “sharp composite image, was made through narrow-band filters, combining emission from the nebula's hydrogen, sulfur, and oxygen atoms in green, red, and blue hues.“

Four Astronomical Highlights to Watch in November 

"The Supermoon 

The full moon in November will be super-size, the largest of 2016. "Supermoon" is a recently coined term for when the moon is full and at perigee-its closest point to the earth in its elliptical orbit. Perigee will take place on November 14 when the moon passes about 356,000 km from our planet. The full moon peaks less than three hours later, wowing viewers and causing larger than normal tides along the coast."

Eclipse to Sunset 
Image Credit & CopyrightLuc Perrot (TWAN)

Explanation: September's eclipse of the Sun is documented in the 68 frames of this timelapse composite. Starting at 1pm local time a frame every 4 minutes follow's the progress of the New Moon across the solar disk. Taken near the centerline of the narrow eclipse path, the series of exposures ends with a golden sunset. Balanced rock cairns in the foreground line a beach on the southern side of Reunion Island in the Indian Ocean, near the village of Etang-Salé. Of course, the close balance in apparent size createsdrama in eclipses of the Sun by the Moon as seen from planet Earth. In an annular eclipse, the Moon's silhouette is just small enough to show the solar disk as a narrow ring-of-fire at maximum eclipse phase.

Gerald, thanks for the image of the space station between the moon & earth.

Venus and Saturn Meet in the Morning Sky

January 7, 2016 By Brian Ventrudo

"Look to the southeastern sky before dawn on January 9 to see Venus and Saturn make a close approach to each other before sunrise. Venus is the brighter of the two, about 60x brighter than Saturn. The two planets make their closest approach at about 4h Universal Time when they are just 1/10 of a degree apart. This timing favors observers in Europe and Africa."

Chicago in Winter

Thanks, Loren for your invitation to watch CBS Sunday morning. I also found this photo that may interest Carl and the Illinois members.

CBS Sunday Morning did a piece this morning about preserving the night sky and minimizing light pollution.  It's worth a look!

Right of centre is the transiting space station.
