That is not an artist's interpretation, but an actual proto-planetary disk around HL Tauri.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339361.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339361.page GMT Detailed planet formation image http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339378.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339378.page GMT Detailed planet formation image http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339496.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339496.page GMT Detailed planet formation image ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339665.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7339665.page GMT Detailed planet formation image

A few centuries here or there make no difference, planetary coalescence takes hundreds of millions of years. ts nice to look at a planetary system in its infancy]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342699.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342699.page GMT Re:Detailed planet formation image http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342725.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342725.page GMT Detailed planet formation image

Actually, we are finding out that planetary formation may take considerably less time, which is the main reason why this image is important.

What we know about HL Tauri suggests that the star is most likely close 100,000 years old and definitely no more than a million years old, a practical newborn as far as stars are concerned, and the structure of the disk is the result of large planetary bodies already formed.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342727.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342727.page GMT Detailed planet formation image

Is our own geological history being rewritten, this evidence is certainly news to me.
I was brought up with earlier thinking on planetary cosmology back before we could observe extra-solar planets; and frankly mostly worked to fit paleantological timelines.
Should we be reassessing how quickly after formation life started on earth, or by extension reassessing the age of the earth?

Our geological history is not being rewritten. If you are asking that question because this new information might lend credence to something like creationism; no.

The age of our Solar System are accurately documented so finding a system that formed more quickly isn't going to make the information we have about our solar system invalid.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342870.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7342870.page GMT Re:Detailed planet formation image No?
Well that is going to be some bad news for some of the simpler and gullible on this world

It is an awesome find and shot, almost as good as the Pillars of Creation shot.

This goes along way in validating some of the early solar system formation theorems]]> http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7345782.page http://www.dakkadakka.com/dakkaforum/posts/preList/622330/7345782.page GMT Re:Detailed planet formation image

No?
