Many Billions of Rocky Planets in Habitable Zones

Recommended Posts

I just noticed that none of these habitable planets is in the Romulan Neutral Zone. What's up with that??

Life span has not even doubled since the beginning of the 20 th century. It has increased maybe 60 percent. In any case this is a trivial increment from the stand point of interstellar travel.

Aside from life span our propulsion technology is just about where the Chinese had it 2000 years ago. We are still sending up solid propellant sky rockets.

But guidance has gotten a lot better.

If human transportation could near the speed of light, we could be at “Teegarden’s Star” in 12 years. I would send an unmanned probe to reconnoiter, with a scientific vehicle to land and explore the two temperate planets. Peter   

From National Geographic. A tiny, old star just 12 light-years away might host two temperate, rocky planets, astronomers announced today. If they’re confirmed, both of the newly spotted worlds are nearly identical to Earth in mass, and both planets are in orbits that could allow liquid water to trickle and puddle on their surfaces.

Scientists estimate that the stellar host, known as Teegarden’s star, is at least eight billion years old, or nearly twice the sun’s age. That means any planets orbiting it are presumably as ancient, so life as we know it has had more than enough time to evolve. And for now, the star is remarkably quiet, with few indications of the tumultuous stellar quakes and flares that tend to erupt from such objects.

These factors, plus the system’s relative proximity, makes the system an intriguing target for astronomers seeking to train next-generation telescopes on other worlds and scan for signs of life beyond Earth.
