APOD: 2022 December 28 - Messier 88 Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2022 December 28 Messier 88 Image Credit &Copyright:Adam Block,Mt. Lemmon SkyCenter,U. Arizona Explanation: Charles Messierdescribed the 88th entry in his 18th century catalog ofNebulae and Star Clustersas a nebula without stars.Of course thegorgeous M88is now understood tobe a spiral galaxy full of stars, gas, and dust, not unlikeour own Milky Way.In fact, M88 is one of the brightest galaxies in theVirgo Galaxy Clustersome 50 million light-yearsaway.M88's beautiful spiral arms are easy to trace in thissharp cosmic portait. The arms are lined with young bluestar clusters, pinkstar-forming regions,and obscuring dust lanesextending from a yellowishcore dominated by an older population of stars.Spiral galaxy M88 spans over 100,000 light-years.

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2022 December 29 Horsehead and Flame Image Credit &Copyright:Jason Close Explanation: The Horsehead Nebula,famous celestialdark marking also known as Barnard 33,is notched against a background glow of emission nebulae inthis sharp cosmic skyscape.About five light-years "tall" the Horsehead lies some 1,500 light-years away in the constellation of Orion.Within the region's fertile molecular cloud complex,the expanse of obscuring dust has a recognizable shape onlyby chance fromour perspectivein theMilky Waythough.Orion's easternmost belt star, bright Alnitak,is to the left of center. Energetic ultraviolet light fromAlnitak powers the glow ofdusty NGC 2024, the Flame Nebula, just below it.Completing a study in cosmic contrasts, bluish reflectionnebula NGC 2023 is below the Horsehead itself.This well-framed telescopic field spans about 3 full moons onthe sky.

APOD: 2022 December 27 - A Full Circle Rainbow over Norway Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2022 December 27 A Full Circle Rainbow over Norway Image Credit & Copyright: Lukas Moesch Explanation: Have you ever seen an entire rainbow?From the ground, typically, only the top portion of a rainbow is visible because directions toward the ground have fewer raindrops.From the air, though, the entire 360-degree circle of a rainbow is more commonly visible.Pictured here, a full-circle rainbow was captured over the Lofoten Islands of Norway in September by a drone passing through a rain shower.An observer-dependent phenomenon primarily caused by the internal reflection of sunlight by raindrops, the rainbow has a full diameter of 84 degrees.The Sun is in the exact opposite direction from the rainbow's center. As a bonus, a second rainbow that was more faint and color-reversed was visible outside the first.

APOD: 2022 December 26 - NGC 6164: Dragons Egg Nebula and Halo Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2022 December 26 NGC 6164: Dragon's Egg Nebula and Halo Image Credit & Copyright: Russell Croman Explanation: The star at the center created everything. Known as the Dragon's Egg, this star -- a rare, hot, luminousO-typestar some 40 times as massive as the Sun -- created not only the complex nebula (NGC 6164) that immediately surrounds it, but also the encompassing blue halo.Its name is derived, in part, from the region's proximity to the picturesque NGC 6188, known as the fighting Dragons of Ara.In another three to four million years the massive star will likely end itslife in a supernova explosion.Spanning around 4 light-years,the nebula itselfhas a bipolar symmetry making it similar in appearance to more common planetarynebulae - the gaseous shroudssurrounding dying sun-like stars.Also like many planetary nebulae, NGC 6164 has been found to havean extensive, faint halo, revealed in blue in this deep telescopic image of the region.Expanding into the surroundinginterstellar medium,the material in the blue halo was likely expelled from an earlier...

APOD: 2022 December 23 - Cassini Looks Out from Saturn Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2022 December 23 Cassini Looks Out from Saturn Image Credit: NASA,JPL-Caltech, Space Science Institute Explanation: This is what Saturn looks like from inside the rings.In 2017, for the first time, NASA directed the Cassini spacecraft to swoop between Saturn and its rings.During the dive, the robotic spacecraft took hundreds of images showing unprecedented detail for structures in Saturn's atmosphere.Looking back out, however, the spacecraft was also able to capture impressive vistas.In the featured image, taken a few hours before closest approach, Saturn's unusual northern hexagon is seen surrounding the North Pole.Saturn's B ring is the closest visible, while the dark Cassini Division separates B from the outer A. A close inspection will find the two small moons that shepherd the F-ring, the farthest ring discernable. A few months after this image was taken -- and after more than a decade of exploration and discovery -- the Cassini spacecraft ran low on fuel and was directed to enter Saturn's atmosphere, where it surely melted.

Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages.Heroically sized even for aNorse god,Thor's Helmet is about 30 light-years across.In fact, the cosmic head-covering is more likean interstellar bubble, blown with a fastwind from the bright, massive star near the bubble's center.Known as aWolf-Rayet star, the central star is an extremely hot giant thought to be in a brief,pre-supernova stage of evolution.NGC 2359 is located about15,000 light-years away toward the constellation of the Great Overdog.This remarkably sharp imageis a mixed cocktail of data from narrowband filters,capturing not only natural looking stars but details ofthe nebula'sfilamentary structures.The star in the center of Thor's Helmet is expected to explode in a spectacularsupernova sometime within the next few thousand years.

Dusty emission in the Tadpole Nebula, IC 410, lies about 12,000 light-years away in the northern constellation of the Charioteer (Auriga).The cloud of glowing gas is over 100 light-years across,sculpted bystellar winds and radiation from embedded open star cluster NGC 1893.Formed in the interstellar clouda mere4 million years ago, bright newly formed cluster stars are seen all around the star-forming nebula. Notable on the lower-right of the featured image are two relatively dense streamers of material trailing away from the nebula's central regions.Potentially sites of ongoing star formation in IC 410, thesecosmic tadpoleshapes are about 10 light-years long.The image was processed highlighting the emission from sulfur (red), hydrogen (green), and oxygen (blue) gas -- but with the stars digitally removed.
