NASA’s Spitzer Space Telescope has spotted a belt of warm dust swirling around the young star HD 113766. It’s about 424 light-years away, and the formation is interesting because the star is just a bit larger than our sun and the dust belt is right in the sweet spot where temperatures will sustain liquid water.
The age is apparently just right, too. If the star system were too young, the disk would be full of gas and it would be making gas-giant planets like Jupiter instead. If it was too old, planets would have already formed.
