A Great Barrier Reefs, off the coast of Queensland in northeastern Australia is the largest living things on Earth,and even visible from outer space. The 2,300 km.long ecosystem comprises thousands of Reefs and hundreds of Islands made of over 680 types of hard and soft corals. It's home to countless species of colorful fish,moluscs,starfish,plus turtles,dolphins and shark.

How do you think people of the earth would react if they knew that a cataclysmic event such as an asteroid hitting our planet was only 2 weeks away?

For the second time this month, the moon is about to become full. There was one full moon on Aug. 1st/2nd and now a second is tonight. According to modern folklore, whenever there are two full moons in a calendar month, the second one is "blue." Watch & learn more: http://go.nasa.gov/1KuqxyP

How would the Death Star actually work?
Possibly one of the most iconic scenes in sci-fi is when the Death Star destroys Alderaan in Star Wars: Episode IV. How might a real death star work?

Dense Star Clusters Shown as Binary Black Hole Factories http://b4in.org/bK7j

The coalescence of two black holes — a very violent and exotic event — is one of the most sought-after observations of modern astronomy. But, as these mergers emit no light of any kind, finding such elusive events has been impossible so far.

Colliding black holes do, however, release a phenomenal amount of energy as gravitational waves. The first observatories capable of directly detecting these ‘gravity signals’ — ripples in the fabric of spacetime first predicted by Albert Einstein 100 years ago — will begin observing the universe later this year.

When the gravitational waves rolling in from space are detected on Earth for the first time, a team of Northwestern University astrophysicists predicts astronomers will “hear,” through these waves, five times more colliding black holes than previously expected. Direct observations of these mergers will open a new window into the universe.

“This information will allow astrophysicists to better understand the nature of black holes and Einstein’s theory of gravity,” said Frederic A. Rasio, a theoretical astrophysicist and senior author of the study. “Our study indicates the observatories will detect more of these energetic events than previously thought, which is exciting.”
