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.13899261 - Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 200mm telephoto lens for a field of view of 10° x 6.8°. The tail appears to be about 3.5° long here. Taken about 6:30 am MST with the comet as high as it would be, though the sky is already beginning to brighten with the blue of dawn twilight. The distinctive cyan tint of a comet's coma is prominent.13898154 - Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 135mm telephoto lens for a field of view of 10° x 15°. The tail appears to be about 4° long here. Taken about 5:45 am MST. The distinctive cyan tint of a comet's coma is prominent. The comet was in Serpens at the time.13998387 - 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 ta13898382 - Auroral curtains at the zenith, with shades of green and cyan, from the display of September 8, 2018 taken from the Tibbitt Lake site near Yellowknife, NWT.70485921 - 'Close Up Of Frost Crystals With Cyan Lighting; Calgary, Alberta, Canada'71141474 - Branches of hanging cherry tree with blossoms against cyan sky, Bunkyo-ku, Tokyo, Japan71141473 - Branches of cherry tree with blossoms against cyan sky, Bunkyo-ku, Tokyo, Japan71141421 - Cherry Blossom against cyan sky, Bunkyo-ku, Tokyo, Japan14249114 - This is the large Vela Supernova Remnant – visible here as the mostly cyan wisps and strands of starstuff from a star that exploded about 11,000 years ago when it was about 900 light years away. It would have been a spectacular sight in our sky at that time.14249347 - This frames most of the intricate arcs and loops of the Vela Supernova Remnant (SNR), the remains of a star that exploded about 11,000 years ago. It is one of the closest SNRs to Earth, about 900 light years away. Most arcs and segments have no separate catalogue numbers, with the exception of the short straight Pencil Nebula, aka Herschel's Ray, in the lower left corner which is NGC 2736. It is the brightest segment of the Vela SNR visually in a telescope. The nebula complex is marked with lots of cyan arcs emitting oxygen III wavelengths, mixed with regions of red hydrogen-alpha emission.71467145 - Paraglider soaring above the crest of K2 against a cyan pastel sky.14249303 - This is a showpiece of the southern skies, the Large Magellanic Cloud, a member of the Local Group, and a satellite galaxy of our Milky Way, one rich in star forming nebulas and clusters. The LMC is cross between a dwarf irregular galaxy and a barred spiral. The nebulas along its bar and arms show as regions of magenta and cyan, from hydrogen and oxygen emission.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 1746.13999412 - Comet C/2022 E3 (ZTF) in the constellation of Taurus on the night of Feb 10,2023. The comet is the cyan-coloured glow above bright orange Mars at upper left.13999163 - Comet C/2022 E3 (ZTF) in the constellation of Taurus on the night of Feb 10,2023. The comet is the cyan-coloured glow above bright orange Mars.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.13998259 - Comet C/2022 E3 (ZTF) in the constellation of Auriga on the night of Feb 8,2023. The comet is the small cyan-coloured glow above centre. It was technically in Auriga but heading south into Taurus and in front of the Taurus Dark Clouds here at centre. Mars is the bright orange object right of centre.13898788 - The complex area of clusters and nebulosity in central Auriga, including: M38 the Starfish Cluster and its smaller companion cluster NGC 1907; the emission/reflection nebulas NGC 1931, IC 417, IC 410 and IC 405 (from right to left here). Magenta and cyan (from emission and reflection components) IC 405 at right is the Flaming Star Nebula. Between IC 405 and IC 410 is the asterism known as The Little Fish.13998908 - The Local Group spiral galaxy Messier 33 in Triangulum. The galaxy contains a number of cyan-coloured OIII regions of nebulosity.13899697 - The region in Serpens and Ophiuchus containing the Serpens-Ophiuchus (S-O) Double Cluster, here at top left, and the large binocular cluster IC 4655 above the cyan-tinted star Cebalrai, here at right. The S-O pair is made of IC 4756 (left) and NGC 6633 (right).13897449 - Scorpius and Sagittarius rising, with Scorpius coming up on its side, as seen from New South Wales, Australia, April 2, 2016. Mars is the brightest object left of Antares in Scorpius, with fainter Saturn below the reddish pairing of Mars and its rival Antares. The cyan-colored blob at lower left above the trees is Comet Linear/252P, which passed close to Earth the previous month. Many nebulas and clusters are visible along the Milky Way around the Galactic Centre in Sagittarius, which is rising here.13999047 - Comet 2022 E3 (ZTF) at top,as the green fuzzy star above the semi-circle of stars marking the constellation of Corona Borealis,the Northern Crown. The comet was approaching the Sun and Earth at this time (January 3,2023) and was brightening,but even here was visible in binoculars and sporting a short dust tail and cyan-colored coma. ZTF = Zwicky Transient Facility,the telescope used to discover the comet in early 2022.13998977 - The Veil Nebula complex in Cygnus,aka the Cygnus Loop or Cirrus Nebula. This is a remnant of a supernova explosion that occured 5000 to 8000 years ago. It features a mix of red hydrogen-alpha and cyan oxygen III emission for a colourful complex of lacy filaments. The components have the catalogue numbers of NGC 6992-5 (eastern component at left) and NGC 6960 (western component at right,through the star 52 Cygni),and NGC 6974 for the middle area at top called Pickering's Triangle.70059060 - water in movement, padangbai, bali, indonesia, asia, running on a beach, far distance, quit, soul, healing, cyan, emptiness, power, strong, calming down, calm, dreaming, longing for, moving, sea71467963 - summer, aerial view, river, water, mountains, Bavaria, Germany, Europe 71467980 - summer, aerial view, island, bay, fjord, Husøy, Senja, Skaland, Norway, Europe 71467961 - summer, aerial view, islands, bay, Senja, Skaland, Norway, Europe 71467958 - summer, aerial view, beach, Walchensee, lake, Bavaria, Germany, Europe 71467975 - summer, aerial view, bridge, bay, mountains, Lofoten, Nordland, Norway, Europe 71467960 - summer, aerial view, from above, river, water, Bavaria, Germany, Europe 71467956 - summer, aerial view, beach, Walchensee, lake, Bavaria, Germany, Europe 71417832 - Blue and gold macaw71413028 - USA, Washington, Seabeck.
