55 Nights with Saturn

For 55 consecutive nights Mediterranean skies were at least partly clear this summer, from the 1st of July to the 24th of August 2018. An exposure from each night was incorporated in this composited telephoto and telescopic image to follow bright planet Saturn as it wandered through the generous evening skies. Through August, the outer planet’s seasonal apparent retrograde motion slowed and drifted to the right, framed by a starry background. That brought it near the line-of-sight to the central Milky Way, and the beautiful Lagoon (M8) and Trifid (20) nebulae. Of course Saturn’s largest moon Titan was also along for the ride. Swinging around the gas giant in a 16 day long orbit, Titan’s resulting wave-like motion is easier to spot when the almost-too-bright Saturn is digitally edited from the scene. via NASA https://ift.tt/2P1qe3H

The Light, the Dark, and the Dusty

This colorful skyscape spans about two full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region’s massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 is below and right of center, also known as the Cave Nebula. About 10 light-years across the cosmic cave’s bright walls of gas are ionized by ultraviolet light from the hot young stars around it. Dusty blue reflection nebulae, like vdB 155 at upper left, and dense obscuring clouds of dust also abound on the interstellar canvas. Astronomical explorations have revealed other dramatic signs of star formation, including the bright red fleck of Herbig-Haro (HH) 168. Near top center in the frame, the Herbig-Haro object emission is generated by energetic jets from a newborn star. via NASA https://ift.tt/2Opmax7

NASA Awards Contract for Archive Center Operations

NASA has awarded a contract to the University of Alaska at Fairbanks for the continued development and operation of the Synthetic Aperture Radar (SAR) Distributed Active Archive Center (DAAC) for NASA’s Earth Observing System Data and Information System.
