> Around a Sun-like star just 1,300 light-years away, a family of planets has been seen in its earliest moments of conception. Astronomers analyzed the infrared flow of dust and detritus left over from the formation of a baby star called HOPS-315, [2]finding tiny concentrations of hot minerals that will eventually form planetesimals -- the 'seeds' around which new planets will grow. It's a system that can tell us about the very first steps of planet formation, and may even contain clues about how our own Solar System formed.
The findings have been [3]published in the journal Nature .

Is this a place where a SuperNova once happened? (Score:2)
I just always had this "feeling" that after a supernova happened, that the matter that shot out would coalesce back to the same spot, and create a new solar system, except with much more heavy atoms that can only be created by a supernova. I'm just asking opinions.

There was a theory of a "cyclic universe" in which everything started at a point and then expanded outward in the big bang, until gravity draws it all back to a point in the "big crunch" and the cycle repeats perpetually. But that fell out of favor when it was discovered that the expansion of the universe is actually accelerating. It's a pity since intuitively it made sense. Now, we're thought to be part of a process that only happens once, ever, in the universe?
As for individual solar systems, accordin
