For the formation of intelligent life, a planet the size of Jupiter, but not too much bigger, is likely essential. Jupiter has served to clear out a lot of stellar junk which, if it impacted earth, could sterilize the planet. One computer simulation found that without Jupiter, large collisions with earth would be 1,000 times for common.

If the desire is to find another solar system with an intelligent civilization, look for a Jupiter in a stable orbit.

The title and article may say what they desire, yet the best & most tested model we have at our disposal (OUR Sun and OUR solar system) seems to show otherwise quite easily.

My skepticism comes from assume all star forming region are alike. And what about terrestrial planets? We still do not have enough data.

…I would consider 6% a high percentage…

The only planets I care about are the ones that will be like ours but we still can't see them…so who cares if there are few gas giants.

I'm only interested in what Wolf Vishniac has to say about this.

I agree with first poster.. the title is misleading. Should read "Low probability of Forming Large Planets."

In my opinion that's a good thing. Gas giants are relatively worthless. Terrestrials are the holy grail.

I want so badly to dismiss these findings… so to look at something optimistically…

If only 6-12% form planets, this is still A LOT of planets out there.

If the regions they looked at have already formed stars it is likely some of the planets are well into their developmental stages and will not require a great deal of the remaining dust and gas to reach a decent size.
…at least, this is what I choose to believe!

This article is utter nonsense. We will find the majority of stars have planets. This is misleading , just like article that
martian soil is to salty to support life.
