Stereo Mars

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 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.

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.

Supernumerary Rainbows over New Jersey

APOD: 2022 November 27 - Supernumerary Rainbows over New Jersey 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 27 Supernumerary Rainbows over New Jersey Image Credit & Copyright: John Entwistle Explanation: Yes, but can your rainbow do this? After the remnants of Hurricane Florence passed over theJersey Shore, New Jersey, USA in 2018, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of rainbows. Over the course of a next half hour, to the delight of the photographer and his daughter, vibrant supernumerary rainbows faded in and out, with at least five captured in this featured single shot. Supernumerary rainbows only form when falling water droplets are all nearly the same size and typically less than a millimeter across. Then, sunlight will not only reflect from inside the raindrops, but interfere, a wave phenomenon similar to ripples on a pond when a stone is thrown in.In fact, supernumerary rainbows can only be explained with waves, and their noted existence in the early 1800s was considered early evidence of light's wave nature.
