(Space Fellowship) Tyrrhenian Sea and Solstice Sky

Today the solstice occurs at 23:03 Universal Time, the Sun reaching its southernmost declination in planet Earth's sky. Of course, the December solstice marks the beginning of winter in the northern hemisphere and summer in the south. When viewed from northern latitudes, and as shown in the above horizontally compressed image, the Sun will make its lowest arc through the sky along the southern horizon. So in the north, the solstice day has the shortest length of time between sunrise and suns [...]

(Space Fellowship) Apollo 11 Landing Site Panorama

Have you seen a panorama from another world lately? Assembled from high-resolution scans of the original film frames, this one sweeps across the magnificent desolation of the Apollo 11 landing site on the Moon's Sea of Tranquility. Taken by Neil Armstrong looking out his window of the Eagle Lunar Module, the frame at the far left (AS11-37-5449) is the first picture taken by a person on another world. Toward the south, thruster nozzles can be seen in the foreground on the left, while at the r [...]

(Space Fellowship) Horsehead of a Different Color

Sometimes a horse of a different color hardly seems to be a horse at all, as, for example, in this newly released image from NASA's Spitzer Space Telescope. The famous Horsehead nebula makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view. In visible-light images, the nebula has a distinctively dark and dusty horse-shaped silhouette, but when viewed in infrared light, dust becomes transparent and the nebula appears as a wispy arc. Th [...]

(Discovery News) THIS is What it's Like to Reenter the Earth's Atmosphere: Video

In a mesmerizing new video released by NASA, the full reentry of the Orion test space vehicle is chronicled -- and it's a phenomenal 10-minute ride from fiery reentry to sudden splashdown into the Pacific Ocean.

(Discovery News) The Flame Nebula Smolders in New Space Telescope Photo

NASA's Spitzer Space Telescope, which views the cosmos in infrared light, has taken a fresh look at the beautiful Flame Nebula, revealing some fascinating features that would otherwise remain invisible.

(Discovery News) This Is the Most Massive Young Galaxy Cluster Ever Discovered

This image, a composite of x-ray, infrared, and optical data, shows the most massive galaxy cluster ever discovered at its distance: a staggering 9.6 billion light-years away, altogether containing the equivalent mass of 400 trillion suns. Continue reading →

(Space Fellowship) NASA Glenn Research Center Completes Stirling Generator

Researchers at NASA’s Glenn Research Center recently assembled an engineering model Stirling power system using valuable assets that became available after the Advanced Stirling Radioisotope Generator (ASRG) flight project was cancelled in late 2013. This second engineering unit, called the EU2, is electrically heated to simulate future potential radioisotope-fueled systems that could be deployed on robotic missions throughout the solar system. Given their higher power to mass ratio compare [...]

(Space Fellowship) SpaceX Completes First Milestone for Commercial Crew Transportation System

NASA has approved the completion of SpaceX’s first milestone in the company’s path toward launching crews to the International Space Station (ISS) from U.S. soil under a Commercial Crew Transportation Capability (CCtCap) contract with the agency. During the Certification Baseline Review, SpaceX described its current design baseline including how the company plans to manufacture its Crew Dragon spacecraft and Falcon 9 v.1.1 rocket, then launch, fly, land and recover the crew. The company a [...]

(Space Fellowship) Hubble Sweeps a Messy Star Factory

This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian 209. Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study star formation, as their conditions are similar to those thought to exist in the early Universe. Markarian 209 in particular has been studied extensively. It is filled with diffuse gas and peppered with star-forming regions towards its core. This image captures it undergoing [...]

(Discovery News) DNews: Reasons for Methane on Mars that Aren't Biological

Methane is such a promising sign for the existence of biological life that it's hard not to get excited when it's detected on Mars. But Amy Shira-Teitel runs down some other ways the gas could be observed on the Red Planet without their being life.
