13999415 - Comet C/2022 E3 (ZTF) passing Mars in the constellation of Taurus on the night of Feb 10,2023. Mars appears to be at the tip of a dark lane of interstellar dust in the Taurus Dark Clouds. The comet is showing its whitish dust tail and blue ion tail,as well as its cyan coma from diatomic carbon emission. The star cluster at left is NGC 1746.13998596 - The infamous "Green" Comet C/2022 E3 (ZTF) passing by reddish Mars with both in the constellation of Taurus on the night of Feb 11,2023. The comet was 2° south of Mars this night. Mars was embedded in some of the dark obscuring dust clouds in Taurus,creating the dark patchy appearance to the background sky. The comet's coma glows cyan due to emission from diatomic carbon molecules,a common trait of comets. The dust tail and faint ion tail are just visible.13999146 - Comet Nishimura (C/2023 P1) captured at dawn on September 7,2023 with the sky brightening with morning twilight colours. The comet was set amid the stars of the Sickle asterism of Leo the Lion,just rising in the east. The comet sports a faint blue ion tail,with the comet seemingly pointed toward the sunrise point; it was moving down and closer to the Sun at this time.13898314 - Comet NEOWISE (C/2020 F3) in a telephoto lens close-up on July 19, 2020, showing the straight blue ion tail and the curving whitish-yellow dust tail. Even the ion tail was visible in binoculars and traceable out for 12° or so, or two binocular fields. A bit of cyan colour is visible around the head of the comet. The ninth magnitude galaxy NGC 2841 is visible to the right of the comet.71448783 - Captain Ion Ismana looks through binoculars at bridge of river cruise ship NickoVISION (nicko cruises) on the Danube, near Bratislava, Bratislava, Slovakia, Europe71448780 - Captain Ion Ismana looks through binoculars from on board river cruise ship NickoVISION (Nicko Cruises) on the Danube, near Bratislava, Bratislava, Slovakia, Europe13998387 - Comet C/2022 E3 (ZTF) on the night of January 22/23,2023 when it was in Draco,with it near the reddish star Edasich (aka Iota Draconis) at top,and the edge-on galaxy NGC 5907 below the comet. To the right of that galaxy is NGC 5866,aka M102. The dust tail of the comet was showing a strong anti-tail spike ahead of the comet's greenish coma,as this was two days before we crossed the plane of the comet's orbit when we would see its dust tail "edge-on." The coma of the comet is strongly cyan or green from glowing diatomic carbon molecules,common for comets. There was little sign of the blue ion ta13900057 - A close-up of Comet NEOWISE (C/2020 F3) on the night of July 14/15, 2020 with a 135mm telephoto lens, and cropped in somewhat. But the field is about 10° high and the white dust and blue ion tails extend across the frame and beyond it. Some of the banding structure in the dust tail is visible.13899504 - Comey Lovejoy, C/2014 Q2, nearest the Pleiades star cluster, Messier 45, on the night of Sunday, January 18, 2015, with its blue ion tail almost passing over the cluster. This is a stack of 6 x 2 minute exposures at f/2.5 with the 135mm lens and Canon 5D MkII at ISO 1600, on the Sky-Watcher Star Adventurer tracker. Taken from City of Rocks State Park, New Mexico, Some haze was passing thru this night but this is a stack of the cleanest frames.13898737 - A selfie observing Comet NEOWISE (C/2020 F3) with binoculars on the dark moonless night of July 14/15, 2020 from Dinosaur Provincial Park, Alberta. A faint aurora colours the sky green and magenta. The faint blue ion tail of the comet is visible in addition to its brighter dust tail. The ground is illuminated by starlight and aurora light only.13899867 - A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 17, 2015, showing structure in the ion gas tail, in the form of streamers and discontinuities in the tail.13899076 - Comet Lovejoy, C/2014 Q2 amid the clusters, nebulas and dark dust clouds of Taurus and Perseus, on Friday, January 16, 2016. Its long blue ion tail stretches back at least 15°, almost to the open cluster NGC 1647 on Taurus at the left edge. At centre is the Pleiades star cluster, M45; at top right is the red California Nebula, NGC 1499, in Perseus, while the field is filled with the dark dusty lanes of the Taurus Dark Clouds. At left is the red giant star Aldebaran amid the V-shaped Hyades star cluster.13898512 - A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 19, 2015. I shot this from near Silver City, New Mexico, using a TMB 92mm apo refractor at f/4.4 and using a Canon 6D at ISO 1600 for a stack of 4 x 5 minute exposures. The ion tail is primarily from a single exposure to minimize blurring from the comet’s motion relative to the stars. The rest of the image is from the stacked combination to minimize noise.13897910 - This is Comet NEOWISE (C/2020 F3) over the Horseshoe Canyon formation near Drumheller, Alberta on the night iof July 10-11, 2020, taken about 2 a.m. MDT with the comet just past lower culmination with it circumpolar at this time. Warm light from the rising waning gibbous Moon provides the illumination. The comet’s faint blue ion tail is just barely visible even in the moonlit sky and low altitude. The glow of summer perpetual twilight at latitude 51.5° N still colours the northern horizon despite this being close to the middle of the night.13897728 - Comet NEOWISE (C/2020 F3) over the still waters this night of Crawling Lake in southern Alberta. The Big Dipper is at top. Even in this short exposure, the two tails — dust and ion — are visible. This was July 20, 2020. The blue ion tail is extending up into the Bowl of the Big Dipper, for some 20° in length. Very impressive!13999563 - The Geminid meteor shower of 2022,showing two bright Geminids leaving yellowish ion trails or "smoke" trains in their wake. The two meteors appeared about 45 minutes apart but are blended together here.13898763 - Comet NEOWISE (C/2020 F3) reflected in the still waters this night of Crawling Lake in southern Alberta. A dim aurora at right colours the sky magenta. Lingering twilight colours the sky blue. A meteor or more likely a flaring satellite appears at right and is also reflected in the water. Even in this short exposure, the two tails — dust and ion — are visible. This was July 20, 2020.13899168 - A scene looking west on January 16, 2015 but with a field stretching up to and beyond the zenith overhead, taking in the Zodiacal Light stretching up to the Pleiades at upper left. Just below the Pleiades is green Comet Lovejoy, with its faint ion tail pointing away from the Sun along the same plane as the Zodiacal Light, as it should. Ion tails always point directly away from the Sun, as they are blown out by the solar wind. Comet Lovejoy was crossing the ecliptic this night, as it heads north in its orbit traveling almost perpendicular to the ecliptic plane.70153746 - cruise on the Nile, fishermen in boat ion front of bank with palm trees, Nile between Luxor and Dendera, Egypt, Africa71209340 - Cooked crayfish ion a fish shop on Kangaroo Island70148410 - ion X, Gymnastics, Health, Healthy, Human, Indoor, Indoors, Inside, Interior, Looking at camera, One70517267 - ION Orchard shopping mall at night, Orchad Road, Singapore.70118807 - ion, Facial expressions, Female, Foam, Foamy, Froth, Generation X, Grin, Grinning, Happiness, Happy70118757 - ion, Facial expressions, Gesture, Gestures, Gesturing, Half-naked, Human, Indoor, Indoors, Inside, In71085138 - ION Orchard Shopping Mall on Orchard Road, Singapore, Southeast Asia70517270 - ION Orchard shopping mall at night, Orchad Road, Singapore.70152613 - ion X, Horizontal, Human, Leg, Legs, Low angle view, Male, Man, Men, One, One person, Outdoor, Outdoo71042524 - Nutmeg sculpture outside ION Orchard shopping mall, Orchard Road, Singapore, Southeast Asia, Asia70517268 - ION Orchard shopping mall at night, Orchad Road, Singapore.70153026 - Car braking ion a curvy road.
