Have geologists discovered all the big craters on Earth?

The Meteor Crater is "only" 1 mile across - craters larger than this are becoming increasingly harder to discover... because we may have discovered them all.

Mars has over 250,000 craters created by asteroid impacts, the Moon has millions – too many to count. But the Earth has an atmosphere, which means we’re protected against most threats and we have much to be thankful for. But even the craters that we do have are constantly eroded by wind and water, so finding and identifying them is quite a challenge.

Alien pyramid on Ceres? More like bad media on Earth

Ceres-pyramid

The whole media is abuzz after NASA released some pictures of the dwarf planet Ceres, the largest object in the asteroid belt, which lies between the orbits of Mars and Jupiter. But while it’s somewhat expected for pseudoscientists and alien fanatics went crazy after they spotted what appears to be a huge pyramid-shaped mountain, I was expecting more from the mainstream media. I know, right?

Astronomers discover huge hydrogen cloud around exoplanet

The Orion Nebula, where the planet "resides"

Astronomers using the Hubble telescope have identified a warm Neptune-sized planet that is “bleeding” a huge hydrogen cloud – thus increasing the odds of finding liquid oceans on gas giants.

Researchers create coldest molecules – colder than interstellar space

Martin

MIT researchers have managed to create incredibly cold molecules, much colder than even interstellar space. In this new experiment, sodium potassium (NaK) molecules were brought down to 500 nanokelvins, just a touch more than 0 Kelvin – the absolute lowest possible temperature.

With NASA’s New Horizons shuttle basically knocking on Pluto’s door, Mark Showalter and Douglas Hamilton present new theories on Pluto’s moons and make predictions about what New Horizons will observe. They propose complex interactions and an intricate “dance” of Pluto’s moons – a miniature version of our solar system.

Young and in its prime: famous California tree is “only” 777 years old

They call it “Tree 76″, because it stands 76 meters tall (249 feet) above the Muir Woods floor in California. Researchers wanted to see how old Tree 76 is, and they were surprised to see how young it is – at only 777 years old, it’s much younger than the oldest known trees of its kind.
