People say trick-or-treat on Halloween day. My parents brought our family from India to USA in 1969. The land of opportunity, freedom... Our nation is the best place on Earth but we are not perfect yet in everything so we can keep working on improving ourselves. We continue to collaborate with India 🇮🇳 and the world 🌎 to overcome global challenges and avoid wars... So on Halloween day, to the flag of the United States of America, I say TREAT. 🇺🇸 https://www.instagram.com/p/CkYVn76O06m/?igshid=NGJjMDIxMWI=

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. https://apod.nasa.gov/apod/ap221031.html #NASA #photography https://www.instagram.com/p/CkYUEsfuMaY/?igshid=NGJjMDIxMWI=

Night on a Spooky Planet Image Credit & Copyright: Stéphane Vetter (Nuits sacrées) Explanation: What spooky planet is this? Planet Earth of course, on a dark and stormy night in 2013 at Hverir, a geothermally active area along the volcanic landscape in northeastern Iceland. Triggered by solar activity, geomagnetic storms produced the auroral display in the starry night sky. The ghostly towers of steam and gas are venting from fumaroles and danced against the eerie greenish light. For now, auroral apparitions are increasing as our Sun approaches a maximum in its 11 year solar activity cycle. And pretty soon, ghostly shapes may dance in your neighborhood too. https://apod.nasa.gov/apod/ap221030.html #NASA #photography https://www.instagram.com/p/CkVo0CRu86G/?igshid=NGJjMDIxMWI=

LDN 673: Dark Clouds in Aquila Image Credit & Copyright: Frank Sackenheim, Josef Poepsel, Stefan Binnewies (Capella Observatory Team) Explanation: Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through planet Earth's skies near bright star Altair. In eerie silhouette against the Milky Way's faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars and astronomers search the dark clouds for telltale signs of star birth. This telescopic close-up looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673, stretching across a field of view slightly wider than the full moon. In the scene, visible indications of energetic outflows associated with young stars include the small red tinted nebulosity RNO 109 above and right of center, and Herbig-Haro object HH32 below. These dark clouds might look scary, but they're estimated to be some 600 light-years away. At that distance, this field of view spans about 7 light-years. https://apod.nasa.gov/apod/ap221029.html #NASA #photography https://www.instagram.com/p/CkTF05qO087/?igshid=NGJjMDIxMWI=

Seven Years of Halley Dust Image Credit & Copyright: Petr Horalek / Institute of Physics in Opava Explanation: History's first known periodic comet Halley (1P/Halley) returns to the inner Solar System every 75 years or so. The famous comet made its last appearance to the naked-eye in 1986. But dusty debris from Comet Halley can be seen raining through planet Earth's skies twice a year during two annual meteor showers, the Eta Aquarids in May and the Orionids in October. Including meteors near the shower maximum on October 21, this composite view compiles Orionid meteors captured from years 2015 through 2022. About 47 bright meteors are registered in the panoramic night skyscape. Against a starry background extending along the Milky Way, the Orionid meteors all seem to radiate from a point just north of Betelgeuse in the familiar constellation of the Hunter. In the foreground are mountains in eastern Slovakia near the city of Presov. https://apod.nasa.gov/apod/ap221028.html #NASA #photography https://www.instagram.com/p/CkQXgcJuL5U/?igshid=NGJjMDIxMWI=

Lucy Spots Earth and Moon. On Oct. 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from 890,000 miles (1.4 million km) away. The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provide Lucy with the speed required to reach the Trojan asteroids — small bodies that orbit the Sun at the same distance as Jupiter. On its 12-year journey, Lucy will fly by a record-breaking number of asteroids and survey their diversity, looking for clues to better understand the formation of the solar system. The image was taken with Lucy’s Terminal Tracking Camera (T2CAM) system, a pair of identical cameras that are responsible for tracking the asteroids during Lucy’s high-speed encounters. The T2CAM system was designed, built, and tested by Malin Space Science Systems; Lockheed Martin Integrated the T2CAMs onto the Lucy spacecraft and operates them.

Sunset, Moonset, Taj Mahal Image Credit & Copyright: Neelam and Ajay Talwar (TWAN) Explanation: On October 25th, Sun and New Moon set together as seen from Agra, India. Their close conjunction near the western horizon, a partial solar eclipse, was captured in this elevated view in hazy skies near the solitary dome of the Taj Mahal. Of course, the partial solar eclipse was also seen from most of Europe, northern Africa, the Middle East, and western parts of Asia. This eclipse was the last of two solar eclipses (both partial eclipses) in 2022. But the next Full Moon will slide through planet Earth's shadow on November 7/8, in a total lunar eclipse. https://apod.nasa.gov/apod/ap221027.html #NASA #photography https://www.instagram.com/p/CkNtrcluqhI/?igshid=NGJjMDIxMWI=

Cocoon Nebula Wide Field Image Credit & Copyright: Andy Ermolli Explanation: When does a nebula look like a comet? In this crowded starfield, covering over two degrees within the high flying constellation of the Swan (Cygnus), the eye is drawn to the Cocoon Nebula. A compact star forming region, the cosmic Cocoon punctuates a nebula bright in emission and reflection on the left, with a long trail of interstellar dust clouds to the right, making the 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 helps clear out a 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, stars that can be seen at infrared wavelengths. https://apod.nasa.gov/apod/ap221026.html #NASA #photography https://www.instagram.com/p/CkLXf7MOqLu/?igshid=NGJjMDIxMWI=

Clouds Around Galaxy Andromeda Image Credit & Copyright: Andrew Fryhover Explanation: What are those red clouds surrounding the Andromeda galaxy? This galaxy, M31, is often imaged by planet Earth-based astronomers. As the nearest large spiral galaxy, it is a familiar sight with dark dust lanes, bright yellowish core, and spiral arms traced by clouds of bright blue stars. A mosaic of well-exposed broad and narrow-band image data, this deep portrait of our neighboring island universe offers strikingly unfamiliar features though, faint reddish clouds of glowing ionized hydrogen gas in the same wide field of view. Most of the ionized hydrogen clouds surely lie in the foreground of the scene, well within our Milky Way Galaxy. They are likely associated with the pervasive, dusty interstellar cirrus clouds scattered hundreds of light-years above our own galactic plane. Some of the clouds, however, occur right in the Andromeda galaxy itself, and some in M110, the small galaxy just below. https://apod.nasa.gov/apod/ap221024.html #NASA #photography https://www.instagram.com/p/CkGKF31uIP8/?igshid=NGJjMDIxMWI=
