Autumn in the Night Sky ✨
🔭: Indian Astronomical Observatory
🌃: Hanle, India
"What comes to mind when you think of autumn? The cold scent of winter on the wind? Endless hot cups of chai? Golden forests and carpets of crimson leaves?
In Ladakh, autumn signifies glittering night skies, bitter, freezing winds, that cuts through layered jackets, and the occasional howl of a distant Tibetan wolf. This high altitude desert is a landscape of my dreams. Perched on this ridge, I was treated to the most surreal of sights. The giant arm of the Milky Way, gently set beyond the distant horizon. Wild displays of Airglow lit the sky. Bands of orange and greens, dancing in the night. Autumn colours in the sky!
The Himalayan Chandra Telescope peers into the distant universe, unraveling ancient cosmic mysteries. Green bands of Airglow behind, reflect off it's silver dome.
The Himalayan Chandra Telescope (HCT) is one of the highest altitude telescopes in the world, operated by the Indian Institute of Astrophysics. It takes stunning scientific images using it's giant 2 meter primary mirror. How I wish I could hook my camera up to it, and go crazy.
This image is a stacked, tracked panorama. The panorama consists of three rows, each of two horizontal frames. Each frame is a stack of 4x30s tracked images. This was shot using a old canon film lens. 50mm f/1.4 at f/3.2 at ISO 3200. Stacked in DSS and processed in Photoshop."

The Horsehead Nebula in Infrared from Hubble.
While drifting through the cosmos, a magnificent interstellar dust cloud became sculpted by stellar winds and radiation to assume a recognizable shape. Fittingly named the Horsehead Nebula, it is embedded in the vast and complex Orion Nebula (M42). A potentially rewarding but difficult object to view personally with a small telescope, the above gorgeously detailed image was taken in 2013 in infrared light by the orbiting Hubble Space Telescope in honor of the 23rd anniversary of Hubble's launch. The dark molecular cloud, roughly 1,500 light years distant, is cataloged as Barnard 33 and is seen above primarily because it is backlit by the nearby massive star Sigma Orionis. The Horsehead Nebula will slowly shift its apparent shape over the next few million years and will eventually be destroyed by the high energy starlight.

The Parker Solar Probe passed the current record of reaching 26.55 million miles from the sun's surface on October 29th, 2018 as calculated by the Nasa-based team. Although, just 2 days ago NASA announced that signals from the Parker Solar Probe indicated that the spacecraft is fully functioning after skimming by the sun at just 15 million miles from the sun's surface!😱 A status beacon that was sent on November 7th, indicates all instruments are running and collecting data properly. The Parker Solar Probe is planned to study the sun's corona in order to solve some of the long standing mysteries about the sun, and should help improve forecasts of space weather, which can affect spacecraft and astronauts in orbit, as well as communications on Earth. It is accomplishments like these that make me so proud of my species. I am almost reduced to tears by such accomplishments as we are venturing out among the stars and bettering humanity's future in space☺️🙏🏻 .

Here is Epimetheus. Epimetheus (also known as Saturn XI) is an inner satellite of Saturn. It was discovered on December 18, 1966 by astronomer Richard Walker. The mean distance between this moon and Saturn is 151,472 km. Epimetheus has an average orbital speed of 15.87 km/s and an orbital period of 0.69 days. Epimetheus shares a very similar orbit with another Saturn moon named Janus. With dimensions of 129.8 x 114 x 106.2 km and a radius of 36.10 mi (57 km), Epimetheus is certainly one of Saturn’s smaller moons. Epimetheus has an average temperature of =78 k and a surface gravity of 0.01 m/s^2. Most of Epimetheus’ surface is composed of darker material giving it a visual geometric albedo of 0.8. The estimated mass of Epimetheus is (5.266+0.006)x10^17 kg and a density of 0.64 g/cm^3. Several craters larger than 30 km can located on the surface of Epimetheus. Ridges and grooves are present in the surface as well. A large impact crater cover half the surface of this moon. This could possibly provide an explanation for the flattened shape of the southern part of Epimetheus. Some astronomers believe Epimetheus and Janus are from the same celestial body and eventually split into co-orbital satellites early in the solar system’s formation. Several years ago, a faint dust ring was discovered to be present around the region occupied by the orbits of Epimetheus and Janus. The ring has a racial extent of 5000 km and is mainly composed of particles that were blasted off of the surface due to meteoroid impacts.
