Is There Water On The Moon?
The ancient astronomers once deemed the Moon, like Mother Earth, to be awash with water and gave fanciful names to its “seas”.

Solar System The Shape Of An Egg
Millions of textbooks depicting our Solar System as spherical have got it all wrong, according to studies of data sent back from deep space by NASA’s venerable probe, Voyager 2.

Earth’s Cries as Heard from Space
A White Male Figure in the Sky is Shedding Tears for The Planet?
Scientists knew that Earth is crying since the 1970s, but they’ve just recently been able to listen to it.
The “cry” is actually a series of chirp and whistles created by solar wind particles colliding with the Earth’s magnetic field high above the planet, and is called the Auroral Kilometric Radiation (AKR):

Soil On Mars Appears Able To Support Life
They call it the “red planet” because the soil is great for growing tomatoes
“Flabbergasted” NASA scientists said on Thursday that Martian soil appeared to contain the requirements to support life, although more work would be needed to prove it.

Batch of “Super-Earths” Found
Earth like planets common
European researchers said on Monday they discovered a batch of three “super-Earths” orbiting a nearby star, and two other solar systems with small planets as well.

Scientists Surprised to Find Earth’s Biosphere Booming
The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data
since 1997. By monitoring the color of reflected light via satellite,
scientists can determine how successfully plant life is photosynthesizing.
An article from the Financial Post says that recent studies of biosphere imaging from the NASA SEAWIFS satellite indicate that the Earth’s biomass is booming: ‘The results surprised Steven Running of the University of Montana and Ramakrishna Nemani of NASA, scientists involved in analyzing the NASA satellite data. They found that over a period of almost two decades, the Earth as a whole became more bountiful by a whopping 6.2%. About 25% of the Earth’s vegetated landmass — almost 110 million square kilometers — enjoyed significant increases and only 7% showed significant declines. When the satellite data zooms in, it finds that each square meter of land, on average, now produces almost 500 grams of greenery per year.’

Super Flare Captured by NASA
Much like a male peacock spreading his feathers, some stars have
to show a little flare to gain the attention of stars of the opposite sex
On April 25, 2008, NASA’s Swift satellite picked up a record-setting flare from a star known as EV Lacertae. This flare was thousands of times more powerful than the greatest observed solar flare. But because EV Lacertae is much farther from Earth than the sun, the flare did not appear as bright as a solar flare. Still, it was the brightest flare ever seen from a star other than the sun.

‘Fire Scars’ Shown on Scorched Earth Map
Africa obviously has their share of pyromaniacs
A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium.

Space Elevator and the Controversial ‘Wobble’ Problem
If an elevator stretching from Earth into space could ever be built, it could slash the cost of space travel. But a controversial new study suggests that building and maintaining one would be an even bigger challenge than previously thought, because it would need to include built-in thrusters to stabilize itself against dangerous vibrations.
Photos and video after the jump.

All The Water And Air On Earth Gathered Into Spheres And Compared To The Earth
Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc.
Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth.

Iraqi TV Debate: Is the Earth Flat?
When it was announced that a war was coming, Iraq went through a major brain drain as the best and the brightest chose to leave the country. They will only return when it’s safe to come home. As a result, these are the type of people making decisions in their country.
I don’t believe many countries would have given airtime to this argument, but its fascinating to see how they twist the facts to fit their understanding of the world.
