COMET 46/P WIRTANEN AND GEMINIDS SHOWER Taken by Juan Carlos Casado on December 14, 2018 @ Albanyà, Girona, SPAIN



Just finished processing the images of the last Geminid meteor shower.

The image is a composition from almost 800 images of the Geminids captured the night of 14 to 15 December 2018. The fireball in the upper right corner was so bright that it briefly illuminated the landscape and left a good wake visible.

On the left you can see the bright star Aldebaran and the Hyades cluster, on the right the Pleiades star cluster with the nebulosities around it in Taurus constellation.

The red emission nebulosity that appears in the lower left surrounds the star Lambda Orionis.

The scene is completed in the lower area with comet 46p / Wirtanen at its maximum brightness and approach to our planet.

Images obtained from the small village of Albanyà, province of Girona, Spain.

Technical data: Sony A7s camera modified with Optolong L-Pro clip filter, 85 / 1.4 objective, 6s exposures, ISO 6,400.

NGC 1365: MAJESTIC ISLAND UNIVERSE Image Credit & Copyright: Martin Pugh




Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.

PERIODIC COMET 46P/WIRTANEN AND STEVE Taken by Harlan Thomas on December 28, 2018 @ NorthWest of Clgary on Highway 766



Paying attention to the solar wind usually pays off and tonight was no exception, based on the news feed from Spaceweather.com, I knew that a CRI was due and if I paid attention to the NOAA Solar Wind, I may get an opportunity to catch some auroral activity. Its really been a aurora drought here in Alberta the last glimpse we had was back in October. Tonight the drive out Highway 766 paid off in spades, not only did I catch a decent auroral show, STEVE made an appearance and passed by Comet 46P Wirtanen, what a treat that was!

RARE MOON DOGS Taken by Raymund Sarmiento on December 27, 2018 @ Nasugbu Batangas Phili



A very very rare phenomenon called Moon Dog lights up the dark cloudy skies of Nasugbu. These are the two rare bright circular spots with comet like tails on each side of a 22 deg lunar halo. Captured at Punta Fuego beach club using a Mate 20 Pro in wide field long exposure mode. The earphone was used as a remote trigger (or the built-in timer) for a jitter free long exposure shot.

M100: A GRAND DESIGN SPIRAL GALAXY Image Credit: NASA, ESA, Hubble




Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice's Hair (Coma Berenices). This Hubble Space Telescope image of M100 was taken recently with the Wide Field Camera 3 and accentuates bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe.

NGC 6357: THE LOBSTER NEBULA Image Credit: Dean Carr



Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion.

THE GREAT CARINA NEBULA Image Credit & Copyright: Maicon Germiniani



A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up reveals remarkable details of the region's central glowing filaments of interstellar gas and obscuring cosmic dust clouds. The field of view is over 50 light-years across. The Carina Nebula is home to young, extremely massive stars, including the stars of open cluster Trumpler 14 (above and left of center) and the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun. Eta Carinae is the brightest star, centered here just below the dusty Keyhole Nebula (NGC 3324). While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory.
