28 New Planets Found Outside Solar System
elkcsr writes "The San Jose Mercury news reports on the phenomenal discovery of 28 new extra-solar planets out there in our galaxy. All of them are outside of the band scientists consider necessary for supporting life as we know it, but the solar systems analyzed should still be quite familiar to those of us in this neck of the woods. System layouts feature small rocky planets towards the star and gas giants further out. The biggest difference seen is a preference for elliptical orbits, instead of generally circular orbit we enjoy. ' For example, the team also described new details about one specific exoplanet, discovered two years ago. This planet, which circles the star Gliese 436, is thought to be half rock, half water. Its rocky core is surrounded by an amount of water compressed into a solid form at high pressures and low temperatures. It makes a short, 2.6-day orbit around Gliese 436. Based on its radius and density, scientists calculate that it has the mass of 22 Earths, making it slightly larger than Neptune. "The profound conclusion is, here we've found yet another type of planet that is already represented in our solar system," Marcy said.'"
To their credit it did say "life as we know it" not just "life in general"
"Is that dad? Either that or Batman's really let himself go."
I have only been to two other countries and has not seen most of the world yet and they are finding new planets.My life is too short and the universe is too big :)
More to the point, not even a hundred years elapsed between the time we made the first tentative experiments with radio and the point at which we developed the technology to wipe life off the planet with the machinery of war.
This doesn't even comprehend accidental or intentional sterilization of the globe with some new biological weapon or experiment not yet comprehended.
It's possible that over the long term, only the not-as-smart-as-us lifeforms survive.
We'd have to find each other not just in space, but in time as well. And the realities of time in space travel mean there may no longer be a welcoming committee there by the time we put down the gangway.
