ARP 188 AND THE TADPOLE'S TAIL Image Credit: Hubble Legacy Archive, ESA, NASA; Processing: Faus Márquez (AAE)



Why does this galaxy have such a long tail? In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a mere 420 million light-years distant toward the northern constellation of the Dragon (Draco). Its eye-catching tail is about 280 thousand light-years long and features massive, bright blue star clusters. One story goes that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole by their gravitational attraction. During the close encounter, tidal forces drew out the spiral galaxy's stars, gas, and dust forming the spectacular tail. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper right. Following its terrestrial namesake, the Tadpole Galaxy will likely lose its tail as it grows older, the tail's star clusters forming smaller satellites of the large spiral galaxy.

COMET WIRTANEN AND STAR CLUSTERS (IMPROVED) Taken by Petr Horálek on December 10, 2018 @ Ustupky, Czech Republic



As the comet Wirtanen gets closest to the Earth, it also gets to one of the most beautiful part of the sky – the constellation Taurus with star clusters Pleiades (upper left) and Hyades (lower left). Weather in the Czech Republic is, however, very bad, so I was truly lucky for about 17 minutes of clear skies. Not quite enough for some truly deep imaging, but still worthy for capturing all three object in one view. Comet Wirtanen is now about twice bigger in the sky than the full Moon and its angular diameter still grows. On 16th December, during its closest approach to Earth, the comet will project very close to the Pleiades… Used Canon 6D Baader IR midified, Sigma 50 mm, f3.2, ISO 6400, 33×30 s from Vixen Polarie mount (darkframes applied).

COMET WIRTANEN - SPECTACULAR EVENING COMET Taken by Chris Schur on December 8, 2018 @ Payson, AZ



Spectacular easy naked eye comet, appearing as a huge 1 degree misty cloud to the eye. In the telescope the view is breathtaking! And it is a photographers dream. Too big to fit in a conventional telescope, here I imaged it with a small short focus refractor to get the starry field and the gorgeous teal colored comet. So exciting!

SPECTACULAR LIGHTNING STRIKE Taken by Peter Lowenstein on December 8, 2018 @ Mutare, Zimbabwe






On Saturday 8th December another early rainy season thunderstorm moved in from the north-west with much lightning, very loud claps of thunder and a cloudburst of torrential rain and hail driven by almost hurricane force gusts of wind. Just after the storm had passed overhead there was a spectacular lightning strike on a tree in Murambi Suburb which momentarily lit up with bright orange flame as shown in the accompanying still frame capture, time-lapse animations and mosaics. 24 mm of rain fell in less than half an hour and there was some damage to trees and plants in gardens.

WIRTANEN WIDE-ANGLE Taken by Alan Dyer on December 8, 2018 @ near Gleichen, Alberta



This was Comet Wirtanen / 46P on December 8, 2018 with it traveling north through Eridanus about to enter Taurus for its encounter in a week or so with the Hyades and Pleiades star clusters. Orion is to the left, and Taurus with the Pleiades at top. The comet is the green glow at bottom right.

This is a stack of 6 x 2-minute exposures, tracked on the Star Adventurer Mini, with the Canon 35mm L lens at f/2.8 and Canon 6D MkII (stock) at ISO 1000.
Bands of red and brown airglow discolour the field, a common sight in this southerly area of the sky from home. I can rarely shoot wide-angle shots of Orion and not have it tinted with airglow. This was from home in southern Alberta at latitude 51° N.

Could almost see it with the naked eye if you let your eyes adjust to the dark long enough. Having sky charts to show where it was sure did help but seeing the big green ball of gas in the back of the camera was very cool too.

SEBASTIAN KRÄMER UND DAS METROPOLIS ORCHESTER BERLIN - IM PLANETARIUM (LIVE)

COMET 46P/WIRTANEN Taken by Kevin Palmer on December 7, 2018 @ Bighorn Mountains, Wyoming



Ive been wanting to get an image like this for many years. But I had doubts that it was possible. Comet 46P/Wirtanen would only be positioned over this peak in the Bighorn Mountains for perhaps 3 nights. The chances of having a bright comet with clear skies and no wind on a December night in Wyoming were very slim. But somehow everything came together at 2:45AM this morning. The temperature hovered around 0°F, but I didnt care.

This image was shot with a Nikon D750 and a Nikon 180mm f2.8 lens. To capture the scene first I shot a 4-frame mosaic of the comet when it was higher in the sky, with 2.5 minute exposures using a tracking mount. Then I turned off the tracking and shot a time-lapse of the comet setting to later use for reference so I could position and align the comet exactly as it appeared behind Loaf Mountain. After the comet set, I shot 2 15-minute images of the mountain. Then I combined all 6 images as accurately as I could.

The comet is about 3X the size of the moon here, but its hard to say exactly since the outer atmosphere is so diffuse. There is a hint of a tail at 12:00.

COMET CLOSEUP Taken by Alan Dyer on December 6, 2018 @ near Gleichen, Alberta



Heres a telescopic view of Comet Wirtanen / 46P on December 6, 2018 with it in the field with several moderately bright stars in Eridanus. A faint ion tail is visible extending upwards at the “10 o’clock” position, which is more or less the comet’s direction of travel. Taken from home in southern Alberta.

The comet was passing through the Clarke Belt this night so some geosynchronous satellite trails appeared in some frames, requiring a median stack mode and some cloning to eliminate.

This is a stack of 3 x 2-minute exposures aligned on the stars, and a stack of 3 x 1-minute at ISO 3200 and 3 x 1-minute at ISO 1600, each set aligned on the moving comet, with those short exposure stacks aligned to the core of the comet to provide a less trailed and not too over-exposed nucleus core.

All with the A&M 105mm apo refractor and Hotech field flattener for f/6.2, and stock Canon 6D MkII. All processing in Photoshop. Diffraction spikes added for photogenic effect with Astronomy Tools actions.

CELEBRATORY GALAXY PHOTO HONORS 25TH ANNIVERSARY OF NASA'S FIRST HUBBLE SERVICING MISSION



Over the past 28 years Hubble has photographed innumerable galaxies throughout the universe, near and far. But one especially photogenic galaxy located 55 million light-years away holds a special place in Hubble history. As NASA made plans to correct Hubble's blurry vision in 1993 (due to a manufacturing flaw in its primary mirror) they selected several astronomical objects that Hubble should be aimed at to demonstrate the planned optical fix. The magnificent grand spiral galaxy M100 seemed an ideal target that would just fit inside Hubble's field of view. This required that a comparison photo be taken while Hubble was still bleary-eyed. The Wide Field and Planetary Camera 1 was selected for the task. The picture had to be taken before astronauts swapped out the camera with the vision-corrected Wide Field and Planetary Camera 2, in December 1993. Following the servicing mission Hubble photographed the galaxy again, and it snapped into crystal clear focus. The public celebrated with Hubble's triumphant return to the clear vision that had been promised. Jaw-dropping pictures of the vast universe that followed have not disappointed space enthusiasts. Because of the astronaut servicing missions, Hubble's capabilities have only gotten better. To commemorate the 25th anniversary of the first servicing mission, this two-panel photo compares the blurry, pre-servicing 1993 image (left) to a 2009 image (right) taken with Hubble's newer, Wide Field Camera 3 instrument, installed during the last astronaut servicing mission to the space telescope.




These three images are of the central region of the magnificent spiral galaxy M100, taken with three generations of cameras that were sequentially swapped out aboard the telescope, and document the consistently improving capability of the observatory. The image on the left was taken with the Wide Field and Planetary Camera 1 in 1993. The photo is blurry due to a flaw (called spherical aberration) in Hubble's primary mirror. Celestial images could not be brought into a single focus. The middle image was taken in late 1993 with Wide Field and Planetary Camera 2 that was installed during the December 2 – 13 space shuttle servicing mission (SM1, STS-61). The camera contained corrective optics to compensate for the mirror flaw, and so the galaxy snapped into sharp focus when photographed. The image on the right was taken with a newer instrument, Wide Field Camera 3, that was installed on Hubble during the space shuttle servicing mission 4 in May 2009.

DECEMBER'S COMET WIRTANEN Image Credit & Copyright: Juan Carlos Casado (TWAN, Earth and Stars)



Coming close in mid-December, Comet 46P Wirtanen hangs in this starry sky over the bell tower of a Romanesque church. In the constructed vertical panorama, a series of digital exposures capture its greenish coma on December 3 from Sant Llorenc de la Muga, Girona, Catalonia, Spain, planet Earth. With an orbital period that is now about 5.4 years, the periodic comet's perihelion, its closest approach, to the Sun will be on December 12. On December 16 it will be closest to Earth, passing at a distance of about 11.6 million kilometers or 39 light-seconds. That's close for a comet, a mere 30 times the Earth-Moon distance. A good binocular target for comet watchers, Wirtanen could be visible to the unaided eye from a dark sky site. To spot it after dusk on December 16, look close on the sky to the Pleiades star cluster in Taurus.

WINTERGREEN WIRTANEN Taken by Alan Dyer on December 6, 2018 @ near Gleichen, Alberta



This was Comet Wirtanen on December 6 in the early evening, with it now in Eridanus and moving north rapidly. It appears here at upper right, and to the west of the rising Orion the Hunter at far left.

A 35mm lens was just able to frame the scene.

The comet is easy in any binoculars — if you know just where to look. Itll be easier to find, and brighter, once it gets up into Taurus between the Pleiades and Hyades. It appears much as it looks in the photos — as a diffuse glow, though without the cyan-green that shows up in photos.

This is a blend of tracked exposures for the sky and untracked exposures for the ground.
