Space diamond, larger than Earth, spotted by astronomers - Technology & science - Space - Space.com Move over, Hope Diamond. The most famous gems on Earth have new competition in the form of a planet made largely of diamond, astronomers say. The alien planet, a so-called "super-Earth," is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet's mass and radius, and studying its host star's composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates. At least a third of the planet's mass is likely pure diamond.

A Rocket To Nowhere A Rocket To Nowhere The Space Shuttle Discovery is up in orbit, safely docked to the International Space Station, and for the next five days, astronauts will be busy figuring out whether it's safe for them to come home. In the meantime, the rest of the Shuttle fleet is grounded (confined to base, not allowed to play with its spacecraft friends) because that pesky foam on the fuel tank keeps falling off.

Sergeant Stubby the War Dog Sgt. Stubby Sergeant Stubby was a stray, homeless mutt who saved more lives, saw more combat, and performed more badass feats of heroic awesomeness than most people could ever hope to accomplish even WITH the advantage of prehensile thumbs and the ability to utilize 100 percent of their brain power without exploding into a burst of ball lightning. The American version of Voytek the Soldier Bear, this fearless, ass-destroyingly ferocious Pit Bull Terrier started his humble life as most stray animals do – hungry, cold, alone, and stranded in the town of New Haven, Connecticut.

Humanities & Social Sciences Art & Art History Courses The Space Shuttle Since 1981, NASA space shuttles have been rocketing from the Florida coast into Earth orbit. The five orbiters — Columbia, Challenger, Discovery, Atlantis and Endeavour — have flown more than 130 times, carrying over 350 people into space and travelling more than half a billion miles, more than enough to reach Jupiter. Designed to return to Earth and land like a giant glider, the shuttle was the world's first reusable space vehicle. More than all of that, though, the shuttle program expanded the limits of human achievement and broadened our understanding of our world. It all started with STS-1, launched on April 12, 1981, just twenty years to the day after Soviet cosmonaut Yuri Gagarin became the first human in space.

Borobudur Borobudur, or Barabudur, is a 9th-century Mahayana Buddhist Temple in Magelang, Central Java, Indonesia. The monument consists of six square platforms topped by three circular platforms and is decorated with 2,672 relief panels and 504 Buddha statues.[1] A main dome, located at the center of the top platform, is surrounded by 72 Buddha statues seated inside a perforated stupa. It is the world’s largest Buddhist temple,[2][3] as well as one of the greatest Buddhist monuments in the world.[4] Evidence suggests Borobudur was constructed in the 9th century and abandoned following the 14th-century decline of Hindu kingdoms in Java and the Javanese conversion to Islam.[7] Worldwide knowledge of its existence was sparked in 1814 by Sir Thomas Stamford Raffles, then the British ruler of Java, who was advised of its location by native Indonesians.
