[NASA] Prepping the Parker Solar Probe for Space

At NASA’s Goddard Space Flight Center, the Parker Solar Probe is lowered into the 40-foot-tall thermal vacuum chamber. The thermal vacuum chamber simulates the harsh conditions that the spacecraft will experience on its journey through space, including near-vacuum conditions and severe hot and cold temperatures. via NASA http://ift.tt/2Dl77LM

Clouds in the LMC

An alluring sight in southern skies, the Large Magellanic Cloud (LMC) is seen in this deep and detailed telescopic mosaic. Recorded with broadband and narrowband filters, the scene spans some 5 degrees or 10 full moons. The narrowband filters are designed to transmit only light emitted by hydrogen, and oxygen atoms. Ionized by energetic starlight, the atoms emit their characteristic light as electrons are recaptured and the atoms transition to … Read More →

In the Valley of Orion

This exciting and unfamiliar view of the Orion Nebula is a visualization based on astronomical data and movie rendering techniques. Up close and personal with a famous stellar nursery normally seen from 1,500 light-years away, the digitally modeled frame transitions from a visible light representation based on Hubble data on the left to infrared data from the Spitzer Space Telescope on the right. The perspective at the center looks along … Read More →

An Elephant s Trunk in Cepheus

With image data from telescopes large and small, this close-up features the dusty Elephant’s Trunk Nebula. It winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, the cosmic elephant’s trunk is over 20 light-years long. The colorful view highlights bright, swept-back ridges that outline the region’s pockets of cool interstellar dust and gas. … Read More →

Rigel and the Witch Head Nebula

By starlight this eerie visage shines in the dark, a crooked profile evoking its popular name, the Witch Head Nebula. In fact, this entrancing telescopic portrait gives the impression that the witch has fixed her gaze on Orion’s bright supergiant star Rigel. More formally known as IC 2118, the Witch Head Nebula spans about 50 light-years and is composed of interstellar dust grains reflecting Rigel’s starlight. The blue color of … Read More →

Three Galaxies and a Comet

Diffuse starlight and dark nebulae along the southern Milky Way arc over the horizon and sprawl diagonally through this gorgeous nightscape. The breath-taking mosaic spans a wide 100 degrees, with the rugged terrain of the Patagonia, Argentina region in the foreground. Along with the insider’s view of our own galaxy, the image features our outside perspective on two irregular satellite galaxies – the Large and Small Magellanic Clouds. The scene … Read More →

Launch and Landing

A composite of three consecutive exposures, this night skyscape follows the January 7 launch and first stage landing of a Falcon 9 rocket from a beach on planet Earth’s space coast. With the launch from Cape Canaveral Air Force Station, the bright streak beginning farthest left traces the initial phase of the rocket’s flight. A visible upward hook marks the first stage beginning its return trajectory with a “boostback burn” … Read More →
