Two tails of 46P/Wirtanen

two tails of comet 46P by 虞 骏, on Flickr

On the night of December 14, I used a telescope to track Comet 46P/Wirtanen. In this photo with a cumulative exposure time of 100 minutes, you can see two long tails pulled from the both side of the coma. The one on the right is the normal tail opposite the direction of the sun. The one on the left should be a rare antitail.

The halo in the upper left corner should be the glare in the telescope, not the real structure.

In this image I made a 3D reproduction on the computer to show what the inside of the comet would be on the left side, using the interior to demonstrate the relief in bright parts, with the center as the highest point of light. On the right side I did inversion technique as if the center were the darkest part.

Comets are cosmic snowballs of frozen gases, rocks, and dust that orbit the Sun. When a comet's orbit approaches the Sun, it warms up and repels dust and gasses in a giant bright head, larger than most planets . Dust and gases form a tail that moves away from the Sun for millions of miles. Its diameter is estimated at 1.2 km.
Some argue for electrochemical theory that comets, are formed by instance Sio2. Si and o2 are electrically separated, and each oxygen atom is first combined with one hydrogen atom to form the hydroxyl radical, another hydrogen atom to form water. Comets are neglected crystalline rocks. Much of what comets are made can not form in the cold darkness of space.

Thomas Henne, I must tell you how much I love this image and your other one, the one showing us NGC 654, NGC 663 and vdB 6.

Both of your images are splendid examples of "cosmic landscape painting". It is not one object that is in focus, but an entire skyscape, full of stars, clusters and nebulas. The composition and details are splendid and the colors are superb.

Thank you!

Ann

P.S. Can you tell me the designation of the star at lower left that appears to be surrounded by an emission nebula? Or, alternatively, can you tell me the designation of the bright and blue star to the upper right of this apparent emission nebula? There appears to be a star surrounded by a dust-reddened reflection nebula to the lower right of the blue star.

Thank you, Ann!
I'm glad, that you like this images. The star at lower left, that seems to be surrounded by an emission nebula is BD+60 2380 or TYC 4264-678-1.
The dust-reddened reflection nebula is GN 22.14.9 or DG 181.
Here is an annotated image (it's also on my website): Best Regards
Thomas

Thanks! I asked, because I'm interested in hot stars. Thanks to you, I could use Simbad Astronomical Database to find out more about the star that appears to be surrounded by an emission nebula. According to Simbad, its spectral class is B2III, which means it is just hot enough to ionize a faint emission nebula.

Thanks again!

Ann

CHRISTMAS STAR?
Copyright: Alan C Tough

Although it looks like a Christmas ornament here, Canopus (Alpha Carinae) is the second brightest star in the night sky and is, arguably, a candidate for the fabled Star of Bethlehem.

iTelescope T27, Siding Spring Observatory, New South Wales, Australia.
Planewave 27" CDK @ f/6.6, FLI PL09000 CCD, Planewave Alt/Az mount.
Astrodon filters. LRGB = 60 Seconds per filter.
FOV: 27.1 x 27.1 arc-mins.

The California Nebula (NGC 1499) illuminated by the runaway star, Menkib.

This three panel mosaic reveals the California Nebula, roughly 1000 light years from our Solar System. Featured in many photos of this month's comet, 46p as it passed through Perseus, this up close mosaic of the nebula reveals it's subtle hydrogen clouds filled with stars and hiding galaxies behind the wispy clouds.

Merry Christmas
Dear friends, I leave here in advance my sincere merry Christmas to all.
I anticipate my merry Christmas, so I made through the junction of two images my astronomical Christmas tree.
Here in this image times:
1) cone nebula (Christmas tree): captured during the meeting in Mato Grosso- MT - Brazil : https://www.astrobin.com/full/332122/0/
2) Comet 46p / Wirtaner (would be the light at the tip of the star, captured um Jales - SP - Brazil https://www.astrobin.com/full/381842/0/

Some artificial spikes were placed to simulate Christmas balls.

Equipment
1) cone: Apo 80mm ts + cen60ec + asi1600mm + baader LRGB
20 * 150 "GB + 10 * 300" halpha + L
2) Comet 46p: Canon 6D + lens 200mm f2.8 +smarteq: 15 * 60 "

A twisted Geminid meteor
This picture captured on the way to Mt.Siguniang scenery during the Geminid meteor shower.A Geminid meteor taking a twisting path just flies over The Youngest Girls's Peak which is higher than 6200 meters.No one is sure why meteor path becomes twisted,Juergen Rendtel guesses the reason could be the meteor is markedly non-spherical in shape, non-uniform in composition, or electrically charged. Non-uniform meteors, for example, may evaporate more on one side than another, causing a rotating meteor to wobble.
