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 14 Lunar Dust and Duct Tape Image Credit: Apollo 17,NASA Explanation: Why is the Moon so dusty?On Earth, rocks are weathered by wind and water, creating soil and sand.On the Moon, the history of constant micrometeorite bombardmenthas blasted away at the rocky surface creating a layer of powderylunar soil orregolith. For the Apollo astronauts and their equipment,the pervasive, fine,gritty dustwas definitely a problem.Fifty years ago, on the lunar surface in December 1972,Apollo 17 astronautsHarrison Schmitt and Eugene Cernan needed torepair one of their rover's fendersin an effort to keep therooster tails of dustaway from themselves and their gear.This picture reveals the wheel and fender of their dust coveredrover along with the ingenious application of spare maps,clamps, and a grey strip of "duct tape".

APOD: 2022 December 12 - An Unusual Globule in IC 1396 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 12 An Unusual Globule in IC 1396 Image Credit & Copyright: Bernard Miller Explanation: Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the featured image. Jets and winds of particles emitted from this star are also pushing away ambient gas and dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moons.

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 13 An Artful Sky over Lofoten Islands Image Credit & Copyright: Giulio Cobianchi Explanation: Can the night sky be both art and science?If so, perhaps the featured image is an example.The digital panorama was composed of 10 landscape and 10 sky images all taken on the same night, from the same location, and with the same camera. Iconic features in the image have been artfully brightened, and the ground nearby was artfully illuminated.Visible in the foreground is the creative photographer anchoring an amazing view from the rugged Lofoten Islands of Norway, two months ago, by holding a lamp.Far in the distance are three prominent arches: our Milky Way Galaxy on the left, while a scientifically-unusual double-arced aurora is documented on the right.A meteor is highlighted between them.Other notable skylights include, left to right, the Andromeda Galaxy, the planet Jupiter, the star Vega, and the stars that compose the Big Dipper asterism.

APOD: 2022 December 11 - Io in True Color 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 11 Io in True Color Image Credit: NASA, JPL, Galileo Project Explanation: The strangest moon in the Solar System is bright yellow. The featured picture, an attempt to show how Io would appear in the "true colors" perceptible to the average human eye, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes. The intense tidal gravity of Jupiter stretches Io and damps wobbles caused by Jupiter's other Galilean moons. The resulting friction greatly heats Io's interior, causing molten rock to explode through the surface. Io's volcanoes are so active that they are effectively turning the whole moon inside out. Some of Io's volcanic lava is so hot it glows in the dark.

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.
