First Earth-like exoplanet

Friday, September 18th, 2009 | astronomy, science | No Comments

Recently the first Earth like planet outside our own Solar System was found. The article can be found here.

The planet is about twice the diameter of our own Earth with a mass about 5 times that of Earth. We would probably feel rather heavy on that one.

When will we see the next one ? I am sure there are others within our range.

Colliding Planets !!

Monday, August 10th, 2009 | astronomy, science | No Comments

The Spitzer InfraRed Space Telescope, launched a few years ago, has , more or less by accident found the remains of – not one – *but two* rocky planets around a star about 100 light years away.

The two planets, one estimated to be in the order of Earth sized, the other Moon sized , appear to have collided probably a few thousand years ago, very recent in astronomical terms.

More detail can be found at Bad Astronomer Blog

This is, as far as I know, the first, however indirect, evidence of Earth/Moon sized planets.

That is not all : A few days ago it was reported that the Kepler Space Telescope, launched this year, had detected the atmosphere of a planet orbiting another star

Exciting times indeed.
