Some rocky worlds may have lots of water from birth.
"Using the mid-infrared instrument on NASA's James Webb Space Telescope, the scientists discovered water near the center of the planet-forming disk of gas and dust surrounding PDS 70, in the form of hot vapor at a temperature of about 625 degrees F ."Our result shows that water is present in the inner disk of this iconic system where planets similar to Earth may be assembling," Perotti said.
My thoughts, exciting what JWST is showing for some exoplanets studied now. However, all is not so good for dust disks seen with rings and gaps. Do all gaps in protoplanetary discs host planets?, https://arxiv.org/abs/2307.11172Phys.org reported. JWST observations find water for the first time in the inner disk around a young star with giant planets, https://phys.org/news/2023-07-jwst-disk-young-star-giant.
"...However, scientists have not yet found any planets near the PDS 70 disk center so far. Instead, astronomers detected two gas-giant planets farther out, PDS 70 b and c. They accumulated surrounding dust and gas while orbiting their host star during their growth, creating a wide annular gap almost void of any detectable material. Still, any rocky planets forming in a water-rich environment closer to the star would benefit from a water supply at the beginning of their life cycles.
My note, concerning what is or may not be in the *inner PDS 70 disk*, I say wait and see here. PDS 70 system is very different than our solar system.
