APOD: 2022 December 7 - NGC 7293: The Helix Nebula 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 7 NGC 7293: The Helix Nebula Image Credit &Copyright:Tommaso Stella Explanation: A mere seven hundred light years from Earth, toward the constellationAquarius,a sun-like star is dying.The dying star's last few thousand years have produced theHelixNebula (NGC 7293), a well studied and nearby example of aPlanetaryNebula, typical of this final phase of stellar evolution. Combining narrow band image data from emission lines of hydrogen atomsin red and oxygen atoms in blue-green hues,it shows tantalizingdetailsof the Helix, including its bright inner regionabout 3 light-years across.The white dot at the Helix's center is this Planetary Nebula's hot,central star.A simple looking nebula at first glance,the Helix is now understood to have a surprisinglycomplex geometry.

APOD: 2022 December 6 - M16: A Star Forming Pillar from Webb 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 6 M16: A Star Forming Pillar from Webb Image Credit: NASA,ESA,CSA,STScI, Processing & Copyright: Mehmet Hakan Özsaraç Explanation: What’s happening inside this interstellar mountain?Stars are forming.The mountain is actually a column of gas and dust in the picturesque Eagle Nebula (M16). A pillar like this is so low in density that you could easily fly though it -- it only appears solid because of its high dust content and great depth.The glowing areas are lit internally by newly formed stars.These areas shine in red and infrared light because blue light is scattered away by intervening interstellar dust.The featured image was captured recently in near-infrared light in unprecedented detail by the James Webb Space Telescope (JWST), launched late last year.Energetic light, abrasive winds, and final supernovas from these young stars will slowly destroy this stellar birth column over the next 100,000 years.

APOD: 2022 December 5 - Pleiades: The Seven Sisters Star Cluster 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 5 Pleiades: The Seven Sisters Star Cluster Image Credit & Copyright: Blake Estes (iTelescope Siding Spring Obs.) & Christian Sasse Explanation: Have you ever seen the Pleiades star cluster?Even if you have, you probably have never seen it as large and clear as this.Perhaps the most famous star cluster on the sky, the bright stars of the Pleiadescan be seen with the unaided eye even from the depths of alight-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident.The featured 11-hour exposure, taken from the Siding Spring Observatoryin Australia, covers a sky area several times the size of the full moon. Also known as the Seven Sisters andM45,the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). A common legend with a modern twist is that one of the brighter stars faded since the cluster was named, leaving only six of the sister stars visible to the...

APOD: 2022 December 3 - Stereo Mars near Opposition 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 3 Stereo Mars near Opposition Image Credit &Copyright:Marco Lorenzi Explanation: Mars looks sharp in these two rooftop telescope views captured inlate November from Singapore, planet Earth.At the time,Mars was about 82 million kilometersfrom Singapore and approaching itsopposition, opposite the Sun in planet Earth's sky on December 8.Olympus Mons,largest of the volcanoes in the Tharsis Montes region(and largest known volcano in the Solar System), is near Mars'western limb.In both the images it's the whitish donut-shape at the upper right.The dark area visible near center is theTerra Sirenumregion while the long dark peninsula closest to theplanet's eastern limb is Sinus Gomer.Near its tip is Gale crater,the Curiosity rover'slanding site in 2012.Above Sinus Gomer, white spots are other volcanoes in theElysiumregion.At top of the planet is the north polar capcovered with ice and clouds.Taken about two days apart, these images of the samemartian hemisphereform a stereo pair.Look at the center of the frame and cross your eyes untilthe separate images come together to see the Red Planet in 3D....

APOD: 2022 December 4 - Video: Powers of Ten 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. Video: Powers of Ten Video Credit & Copyright: Charles & Ray Eames (Eames Office) Explanation: How different does the universe look on very small scales? On very large scales?The most famous short science film of its generation gives breathtaking comparisons.That film, Powers of Ten, originally created in the 1960s, has been officially posted to YouTube and embeddedhere. From a picnic blanketnear Chicago out past theVirgo Cluster of Galaxies,every ten seconds the film zooms out to show a square a factor of ten times larger on each side.The 9-minute video then reverses, zooming back in a factor of ten every two seconds and ends up inside a single proton.The Powers of Ten sequence is actually based on the book Cosmic View by Kees Boeke in 1957, as is a similar but mostly animated film Cosmic Zoom that was also created in the late 1960s.The changing perspectives are so enthralling and educational that sections have been recreated using more modern computerized techniques, including the first few minutes of the movieContact.Ray...
