Extinct mollusks known as ammonites inhabited the planet for more than 300 million years—almost twice as long as dinosaurs—before disappearing in the mass extinction event more than 65 million years ago. 
As many as 10,000 species may have existed, ranging from tiny organisms that measured only a fraction of an inch across to formidable animals more than 2 feet in diameter, such as the spectacular 75-million-year-old specimen shown above, which is on view in the Museum’s Grand Gallery.

Saturn’s hexagon is a persisting six sided cloud pattern around the north pole of the planet. It is created by a band of upper-atmospheric winds, and the sides of it are about 13,800 km (8,600 mi) long, which is longer than the Earth’s diameter. There’s a hurricane swirling within the hexagon.

If you mean habitable, then it sounds like all minecraft players dreams have come true!image

haha, no I haven’t heard of this, it would be super cool if it were true! Sadly, It seems very unlikely that scientists would be able to determine if an exoplanet has continents. The way that scientists find exoplanets is not by imaging them directly. One method is to detect a slight “wobble” of a star (this would give you very little indication of what the planet is made of):

Another way is to measure “dips” in a stars brightness as an exoplanet crosses in front of it. This would give you slightly more information about the composition of a planet, but not enough to confirm continents.

If you find the article, send it to me! I would love to take a look at it and see how they came to their conclusions. It’s very cool to think about these things, thanks for the ask DFTBA!

One thing I notice about Tumblr is the amount of Feminazis… Like it’s 2013 you have equality! I feel like being a white male is a fucking crime because I apparently oppress everyone…  Like women should have equal rights but Feminazis just put men down using bully tactics, which is what you are accusing men of so use your fucking head! UGH! THIS IS WHY WE CAN’T HAVE NICE THINGS! If you’re a Feminazi please look up The Amazing Atheist! He will explain why you’re wrong.
