This distant world is giant (about eight times the mass of Jupiter) and lies far out from its star (about 330 times the Earth-Sun distance).

But for all the planet's strangeness, its star is quite like our own sun.

Previously, the only photographed extrasolar planets (http://www.space.com/scienceastronomy/050430_exoplanet_image.html) have belonged to tiny, dim objects known as brown dwarfs that not all astronomers consider stars.

And while hundreds of exoplanets (http://www.space.com/businesstechnology/080402-tw-earth-like-planets.html) have been detected by noting their gravitational tug on their parent stars, it is rare to find one large enough to image directly.


I know there are a few space-based telescopes being worked on for the future that will be much better for attempting this type of picture.

Good stuff!:up:

For more info, here's a list of all the extrasolar planets that have been discovered. Stars with planetary systems are very prevalent. I suspect this list to grow exponentially after the Kepler mission in launched sometime next year.

That is cool. At about 1,800 Kelvin it's doubtful to support life.

Wrong.

thts what i never understood. why do we assume whats life needs for support millions of lightyears away?

Exactly. Who says life has to be carbon based?

Photonic based then?
