APOD: 2022 September 7 - Tarantula Stars R136 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 September 7 Tarantula Stars R136 from Webb Images Credit & Copyright: NASA, ESA, CSA, STScI, Webb ERO Production Team Explanation: Near the center of a nearby star-forming region lies a massive cluster containing some of the largest and hottest stars known. Collectively known as star cluster NGC 2070, these stars are part of the vast Tarantula Nebula and were captured in two kinds of infrared light by the new Webb Space Telescope. The main image shows the group of stars at NGC 2070's center -- known as R136 -- in near-infrared, light just a bit too red for humans to see.In contrast, the rollover image captures the cluster center in mid-infrared light, light closer to radio waves. Since R136's brightest stars emit more of their light in the near infrared, they are much more prominent on that image.This LMC cluster's massive stars emit particle winds and energetic light that are evaporating the gas cloud from which they formed.The Webb images, released yesterday, shows details of R136...
APOD: 2022 September 6 - An Iridescent Pileus Cloud over China 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 September 6 An Iridescent Pileus Cloud over China Image Credit & Copyright: Jiaqi Sun （孙嘉琪） Explanation: Yes, but how many dark clouds have a multicolored lining?Pictured, behind this darker cloud, is a pileus iridescent cloud, a group of water droplets that have a uniformly similar size andso together diffract different colors of sunlight by different amounts. The featured image was taken last month in Pu'er, Yunnan Province, China.Also captured were unusual cloud ripples above the pileus cloud. The formation of a rare pileus cloud capping a common cumulus cloud is an indication that the lower cloud is expanding upward and might well develop into a storm.

APOD: 2022 September 5 - Carina Cliffs from the Webb Space Telescope 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 September 5 Carina Cliffs from the Webb Space Telescope Image Credit: NASA, ESA, CSA, STScI Explanation: Stars created these cliffs.Specifically, the destructive winds and energetic light from the stars in the open cluster NGC 3324 eroded away part of a mountain of dark interstellar dust in the northern part of the Carina Nebula.Several of these stars are visible toward the top of this highly detailed image taken recently by the James Webb Space Telescope, the largest astronomical telescope ever launched.Webb's large mirror and ability to see dust-piercing infrared light has enabled it to capture fascinating details in the dust, hundreds of previously hidden stars, and even some galaxies far in the distance. The featured jagged cliffs occur in part of Carina known as the Gabriela Mistral Nebula -- because when viewed in another orientation, they appear similar to the facial profile of the famous Chilean poet. These nebular cliffs occur about 7,600 light years away toward the southern constellation of Carina. Astrophysicists: Browse 2,800+...

Visible far in the distance is the band of our Milky Way Galaxy, appearing to rise from a dark rocky outcrop. Sixteen images were added together to bring up the background Milky Way and to reduce noise. Your Sky Surprise: What picture did APOD feature on your birthday?

APOD: 2022 August 31 - Siccar Point on Mars 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 August 31 Siccar Point on Mars Image Credit: NASA/JPL-Caltech/MSSS;Processing & License:Kevin M. Gill Explanation: What created this unusual hill on Mars?No one is sure. A good outlook to survey the surrounding area, Siccar Point stands out from its surroundings in Gale Crater.The unusual mound was visited by the robotic Curiosity rover exploring Mars late last year.Siccar Point not only has a distinctive shape, it has dark rocks above lighter rocks. The apparent much younger age of the dark rocks indicates a time-break in the usual geological ordering of rock layers -- by a process yet unknown.The Martian hill is named for SiccarPoint on Earth, a place in Scotland itself distinctive as a junction between two different rock layers. Curiosity continues to explore Gale crater on Mars, looking for clues of ancient life.Simultaneously, 2300 kilometers away, its sister rover Perseverance explores Jezero crater, there assisted by the flight-capable scout Ingenuity.
