LDN 43: The Cosmic Bat Nebula

APOD: 2022 October 31 - LDN 43: The Cosmic Bat Nebula 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 October 31 LDN 43: The Cosmic Bat Nebula Image Credit & Copyright: Mark Hanson and Mike Selby;Text: Michelle Thaller (NASA's GSFC) Explanation: What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars.

NGC 6357: The Lobster Nebula

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 November 1 NGC 6357: The Lobster Nebula Image Credit: CTIO/NOIRLab/DOE/NSF/AURA;Processing: T. A. Rector (U. Alaska Anchorage/NSF’s NOIRLab), J. Miller (Gemini Obs./NSF’s NOIRLab), M. Zamani & D. de Martin (NSF’s NOIRLab) Explanation: Why is the Lobster Nebula forming some of the most massive stars known?No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars. The overall red glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. The image was taken with DOE's Dark Energy Camera on the 4-meter Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile.NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion.

Cocoon Nebula Wide Field

In this crowdedstarfield, covering over two degrees within the high flyingconstellation of the Swan (Cygnus),the eye is drawn to the Cocoon Nebula.A compact star forming region,the cosmic Cocoonpunctuates a nebula bright in emission and reflection on the left,with a long trail of interstellar dust clouds to the right, makingthe entire complex appear a bit like a comet.Cataloged as IC 5146, the central bright head of the nebula spans about 10 light years,while the dark dusty tail spans nearly 100 light years. Both are located about 2,500 light years away.The bright star near the bright nebula's center, likely only a few hundred thousand years old, supplies power to the nebular glow as it helpsclear outa cavity in the molecular cloud's star forming dust and gas.The long dusty filaments of the tail, although dark in this visible light image, are themselves hiding stars in the process of formation,...

Jupiter Rotates as Moons Orbit

APOD: 2022 October 25 - Jupiter Rotates as Moons Orbit 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. Jupiter Rotates as Moons Orbit Video Credit & Copyright: Makrem Larnaout Explanation: Jupiter and its moons move like our Sun and its planets.Similarly, Jupiter spins while its moons circle around.Jupiter’s rotation can be observed by tracking circulating dark belts and light zones.The Great Red Spot, the largest storm known, rotates to become visible after about 15 seconds in the 48-second time lapse video.The video is a compilation of shorts taken over several nights last month and combined into a digital recreation of how 24-continuous hours would appear.Jupiter's brightest moons always orbit in the plane of the planet's rotation, even as Earth’s spin makes the whole system appear to tilt. The moons Europa,Ganymede, and Io are all visible, with Europa's shadow appearing as the icy Galilean moon crosses Jupiter's disk. Jupiter remains near opposition this month, meaning that it is unusually bright, near to its closest to the Earth, and visible nearly all night long.
