Rainbows and Rays over Bryce Canyon 

What’s happening over Bryce Canyon? Two different optical effects that were captured in one image taken earlier this month. Both effects needed to have the Sun situated directly behind the photographer. The nearest apparition was the common rainbow, created by sunlight streaming from the setting sun over the head of the photographer, and scattering from raindrops in front of the canyon. If you look closely, even a second rainbow appears above the first. 

More rare, and perhaps more striking, are the rays of light that emanate out from the horizon above the canyon. These are known as anticrepuscular rays and result from sunlight streaming though breaks in the clouds, around the sky, and converging at the point 180 degrees around from the Sun. Geometrically, this antisolar point must coincide with the exact center of the rainbows. Located in Utah, USA, Bryce Canyon itself contains a picturesque array of ancient sedimentary rock spires known as hoodoos.

NASA just confirmed “Earth’s Twin” exists. This is what it means.

 (Video)NASA’s Keplar space telescope confirmed the existence of the 1030th known planet. Even more staggering, it’s the closest thing NASA has found to being Earth’s closest relative. Keplar-452b revolves in a “habitable zone” around a sun-like star and has an orbit time of 382 days and is just 5 percent further than Earth from its parent star. NASA estimates that the planet could be rocky based on its size. Keplar 452b is 60% wider than Earth. Since it began, the Keplar mission has detected 4,696 planets, 1030 of which have been confirmed. To accept the possibility that Earth is the only host to intelligent life is to remain blind to overwhelming probability.

The orbiter Columbia, aboard its orbiter transporter system, rolls toward the opening in the Vehicle Assembly Building where it was mated with the external tank mating in preparation for mission STS-93. The primary mission objective was the deployment of the Advanced X-ray Astrophysics Facility, renamed the Chandra X-Ray Observatory. Mission STS-93 was the first led by a woman, Commander Eileen M. Collins.  The mission launched on July 23, 1999.

im at 215 so i figured i should do one of these!!

NASA researchers find "frozen" recipe for extraterrestrial vitamin

Moffett Field CA (SPX) Jul 28, 2015
Vitamin B3 could have been made on icy dust grains in space, and later delivered to Earth by meteorites and comets, according to new laboratory experiments by a team of NASA-funded researchers. Vitamin B3, also known as niacin or nicotinic acid, is used to build NAD (nicotinamide adenine dinucleotide), which is essential to metabolism and probably ancient in origin. The result supports a theory

Happy Birthday Apollo Program: Today (July 28, 1960) at a series of meetings of The Space Task Group, the Apollo Program was announced. According to wikipedia:

The program was named after the Greek god of light, music, and the sun by NASA manager Abe Silverstein, who later said that “I was naming the spacecraft like I’d name my baby.” Silverstein chose the name at home one evening, early in 1960, because he felt “Apollo riding his chariot across the Sun was appropriate to the grand scale of the proposed program.”

Such great promise for a long period of space exploration fizzled out after the Skylab and Apollo-Soyuz missions were completed. And, oh the future plans for Apollo. The Apollo Applications Program (AAP) had visions of a moon base and possibly a Venus flyby. David S Portree posted an article on Wired in Oct 2014 that described how the Apollo Program might have fared in history.

Even though cut short, the Apollo Program did yield significant scientific and technological results, as Carl Sagan explains in this short video:
