I think its amazing the amount of data they can get from simply observing dips in the stars brightness...
1.4 times as wide as Earth
4.6 times as massive as Earth
Too hot to host life as we know it
Density is about 8.8 times that of water
Mostly made of rock and metal
One side of the planet is likely permanently facing the star
Heating it to around 1400 °C
We expect to find oceans of molten material
The reason it was a big deal:
Planet hunter Geoff Marcy of the University of California in Berkeley, who was not involved in the discovery, said it is "the first definitive
rocky planet ever found" outside the solar system.
The BBC are saying that its a stepping stone to finding "Earth like worlds"
Rocky exoplanet milestone in hunt for Earth-like worlds
I think that in our life time we will find a definite earth like planet but whether we will be able to observe it close up I'm not sure,
I love the idea that if there is life out there that we will be the aliens doing the visiting I really like the idea of aliens looking up in the sky
one day and "we" are the ones who ascend, I like finding things out for ourselves I'd hate it if aliens turned up here and said "here's all knowledge
of the universe... see ya later"... boring, I think there's an excitement to be had about unravelling things ourselves and taking credit for our own
discoveries and I look forward to the day we hear on the news "earth like world found!".
