Stereo Mars near Opposition

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....

Video: Powers of Ten

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...

Pleiades: The Seven Sisters Star Cluster

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 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 unaided eye.The actual number of Pleiades...

The Gum Nebula Supernova Remnant

APOD: 2022 November 29 - The Gum Nebula Supernova Remnant 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 November 29 The Gum Nebula Supernova Remnant Image Credit & Copyright: Victor Lima Explanation: Because the Gum Nebula is the closest supernova remnant, it is actually hard to see. Spanning 40 degrees across the sky, the nebula appears so large and faint that it is easily lost in the din of a bright and complex background. The Gum Nebula is highlighted nicely in red emission toward the right of the featured wide-angle, single-image photograph taken inlate May.Also visible in the frame are the Atacama Desert in Chile in the foreground,the Carina Nebula in the plane of our Milky Way galaxy running diagonally down from the upper left, and the neighboring Large Magellanic Cloud (LMC) galaxy.The Gum Nebula is so close that we are much nearer the front edge than the back edge, each measuring 450 and 1500 light years respectively. The complicated nebula lies in the direction of the constellations of Puppis and Vela. Oddly, much remains unknown about the Gum Nebula, including the timing and...

Leonid Meteors Through Orion

APOD: 2022 November 28 - Leonid Meteors Through Orion 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 November 28 Leonid Meteors Through Orion Image Credit & Copyright: Luo Hongyang Explanation: Where will the next meteor appear?Even during a meteor shower, it is practically impossible to know.Therefore, a good way to enjoy a meteor shower is to find a place where you can sit comfortably and monitor a great expanse of dark sky.And it may be satisfying to share this experience with a friend. The meteor shower depicted was the 2022 Leonids which peaked earlier this month, and the view is from Hainan, China looking out over the South China Sea.Meteor streaks captured over a few hours were isolated and added to a foreground image recorded earlier. From this place and time, Leonid meteors that trace back to the constellation of Leo were seen streaking across other constellations including Orion.The bright red planet Mars appears near the top of the image.Bonding over their love of astronomy, the two pictured meteor enthusiasts, shown celebrating their common birthday this month, are now married. Tomorrow's picture: closest supernova...
