Exciting Times!

Exciting times! Indeed.

European Space Agency’s Rosetta mission successfully placed a small spacecraft on the surface of a speeding comet on Wednesday. Now maybe we will find out of comets filled the oceans of the Earth! Maybe we could find out of organic material exists on comets which could mean life was seeded from outer space.

But of course this news is not for the faint hearted, creationists and conspiracy theorists.

For scientists, one of the central mysteries that Rosetta will explore is whether Earth’s oceans are filled with melted comets.

Since the rocky bits that came together to form the planet were dry, water has to have come from somewhere else. One possibility is that comets slamming into the Earthearly on seeded it with water. http://www.nytimes.com/2014/11/13/science/space/european-space-agencys-spacecraft-lands-on-comets-surface.html

And how big exactly is Rosetta’s comet? Compared to Los Angeles very big.

Fossilised bones of dinosaur believed to be the largest creature ever to walk the Earth has been unearthed in Argentina, palaeontologists say.

Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall. Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus. Scientists believe it is a new species of titanosaur – an enormous herbivore dating from the Late Cretaceous period. Read more: http://ow.ly/wXCu1
