APOD: 2022 September 8 - North America and the Pelican 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 8 North America and the Pelican Image Credit &Copyright: Frank Sackenheim Explanation: Fans of our fair planetmight recognize the outlines of thesecosmicclouds.On the left, bright emission outlined by dark, obscuring dust lanesseems to trace a continental shape, lending the popular nameNorth America Nebulato the emission region cataloged as NGC 7000.To the right, just off the North America Nebula's east coast,is IC 5070, whose avianprofile suggeststhePelican Nebula. The two bright nebulae are about 1,500 light-years away,part of the samelarge and complexstar forming region, almost as nearby as thebetter-known Orion Nebula.At that distance, the 3 degree wide field of view would span80 light-years.This careful cosmic portraituses narrowband images combined to highlight the brightionization frontsand the characteristic glow from atomic hydrogen, and oxygengas.These nebulae can be seen with binoculars from a dark location.

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+...

APOD: 2022 September 4 - Sea and Sky Glows over the Oregon Coast 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 4 Sea and Sky Glows over the Oregon Coast Image Credit & Copyright: Rudy Montoya Explanation: Every step caused the sand to light up blue.That glow was bioluminescence -- a blue radiance that also lights the surf in this surreal scene captured in mid-2018 at Meyer's Creek Beach in Oregon, USA.Volcanic stacks dot the foreground sea, while a thin fog layer scatters light on the horizon.The rays of light spreading from the left horizon were created by car headlights on the Oregon Coast Highway (US 101), while the orange light on the right horizon emanates from a fishing boat. 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?
