APOD: 2018 May 25 - Galaxies Away
This stunning group of galaxies is far, far away, about 450 million light-years from planet Earth and cataloged as galaxy cluster Abell S0740. Dominated by the cluster's large central elliptical galaxy (ESO 325-G004), this reprocessed Hubble Space Telescope view takes in a remarkable assortment of galaxy shapes and sizes with only a few spiky foreground stars scattered through the field. The giant elliptical galaxy (right of center) spans over 100,000 light years and contains about 100 billion stars, comparable in size to our own spiral Milky Way galaxy. The Hubble data can reveal a wealth of detail in even these distant galaxies, including arms and dust lanes, star clusters, ring structures, and gravitational lensing arcs. via NASA

NASA head Jim Bridenstine, once doubtful, confirms he believes humans are the leading cause of climate change - The Washington Post
NASA Administrator Jim Bridenstine, who previously questioned whether humans are primarily responsible for climate change, left no doubt Wednesday that his position has changed. Signifying a striking conversion, he confirmed that he now accepts that humans are, in fact, the leading cause.

Phonesat | NASA
NASA's PhoneSat project will test whether spacecraft can be built using smartphones to launch the lowest-cost satellites ever flown in space. Each PhoneSat nanosatellite is one cubesat unit - a satellite in a 10 cm (approx. 4 inches) cube or about the size of a tissue box - and weighs approximately three pounds.

APOD: 2018 May 24 - The Gum Nebula Expanse
Named for a cosmic cloud hunter, Australian astronomer Colin Stanley Gum (1924-1960), The Gum Nebula is so large and close it is actually hard to see. In fact, we are only about 450 light-years from the front edge and 1,500 light-years from the back edge of this interstellar expanse of glowing hydrogen gas. Covered in this 40+ degree-wide monochrome mosaic of Hydrogen-alpha images, the faint emission region stands out against the background of Milky Way stars. The complex nebula is thought to be a supernova remnant over a million years old, sprawling across the Ship's southern constellations Vela and Puppis. This spectacular wide field view also explores many objects embedded in The Gum Nebula, including the younger Vela supernova remnant. via NASA

NASA Upgrades VHF Communications for International Space Station, Apr 2018
Via Dale Hatfield

"NASA is implementing upgrades to VHF communications ground stations that back up the International Space Station (ISS) primary communications system, the Space Network and communicate with Soyuz spacecraft when out of Russia’s range. The ISS’s first component launched in 1998."

NASA faces ‘significant’ IT management weaknesses, GAO says
‘GAO seems to concur with the IG’s assessment. “Until NASA addresses these [IT governance] weaknesses, it will face increased risk of investing in duplicative investments or may miss opportunities to ensure investments perform as intended,” the report states.’

Must be tough for the CIO types over there with that report.

APOD: 2018 May 22 - Craters and Shadows at the Lunar Terminator
Why does the right part of this image of the Moon stand out? Shadows. The terminator line -- the line between light and dark -- occurs in the featured image so that just over half the Moon's face is illuminated by sunlight. The lunar surface appears different nearer the terminator because there the Sun is nearer the horizon and therefore causes shadows to become increasingly long. These shadows make it easier for us to discern structure, giving us depth cues so that the two-dimensional image, when dominated by shadows, appears almost three-dimensional. Therefore, as the Moon fades from light to dark, shadows not only tell us the high from the low, but become noticeable for increasingly shorter structures. For example, many craters appear near the terminator because their height makes them easier to discern there. The image was taken two weeks ago when the lunar phase was waning gibbous. The next full moon, a Moon without shadows, will occur one week from today. via NASA
