Exoplanets: No Goldi-LUCKS Zone

When watching a television program recently, I heard a character use the old remark that since there are so many stars up yonder, there must be millions of inhabited planets as well. Interest in this obviously increased with the discovery of extrasolar planets.

Astrobiologists (astro, but no biology) and other scientists have come up with the habitable zone. It has to be just the right temperature so water can be present on a planet, and they expected to find a passel of thise planets. It did not go well.

The Goldilocks Zone has been modified by more science. It did not go well. Candidates for abiogenesis planets have greatly diminished to almost zero.

The Goldilocks zone isn't having much luck. It has been modified to include several other factors, such as the temperaments of stars planets are orbiting, space "weather", and more (see "Hopes for Extraterrestrial Life Dimming.") Although Darwinoids spread the false claim that abiogenesis, a.k.a. chemical evolution, has nothing to do with evolution, it's still a priority for naturalists. Since there is no evidence for life being able to begin here, they evosplain that it must have begun out there, thataway.

There were many planets "in the zone", but they keep getting ruled out as potentially supporting life. I reckon Goldilocks was troubled by more than three bears of science.

There is some speculation that Earth is the center of the universe. While that may not be correct, we do know that Earth is the center of God's plan. This would explain why there's not much hope in finding other planets suitable for life — not that we can get to them in the first place.
...after looking through a catalog of over 4,000 known exoplanets (only 49 of which were deemed in the habitable zone) and measuring them against the additional set of criteria, they concluded that only 8 of those 49 planets made the cut. Then after looking more closely at the remaining eight, they decided that most likely seven of those were gas giants and not an Earth-like rocky planet. Typically, planets larger than 1.7 times the size of the Earth are considered gassy planets. The one remaining planet just squeaks by the size requirements, being 1.63 times the size of Earth.
