Smaller Version of the Solar System Is Discovered
NY Times ^ | February 15, 2008 | DENNIS OVERBYE

Astronomers said Wednesday that they had found a miniature version of our own solar system 5,000 light-years across the galaxy — the first planetary system that really looks like our own, with outer giant planets and room for smaller inner planets.

“It looks like a scale model of our solar system,” said Scott Gaudi, an assistant professor of astronomy at Ohio State University. Dr. Gaudi led an international team of 69 professional and amateur astronomers who announced the discovery in a news conference with reporters.

Their results are being published Friday in the journal Science. The discovery, they said, means that our solar system may be more typical of planetary systems across the universe than had been thought.

In the newly discovered system, a planet about two-thirds of the mass of Jupiter and another about 90 percent of the mass of Saturn are orbiting a reddish star at about half the distances that Jupiter and Saturn circle our own Sun. The star is about half the mass of the Sun.

Neither of the two giant planets is a likely abode for life as we know it. But, Dr. Gaudi said, warm rocky planets — suitable for life — could exist undetected in the inner parts of the system.

“This could be a true solar system analogue,” he said.

Sara Seager, a theorist at the Massachusetts Institute of Technology who was not part of the team, said that “right now in exoplanets we are on an inexorable path to finding other Earths.” Dr. Seager praised the discovery as “a big step in finding out if our planetary system is alone.”

Since 1995, around 250 planets outside the solar system, or exoplanets, have been discovered. But few of them are in systems that even faintly resemble our own. In many cases...

Everybody in that system drives a Prius. Or a clown car.

Or is there a difference?

No crap? Well, better alert all the scientists of the world, tell ‘em to just quit now. Wish I had your omniscience.

Hubris is one thing. Is there a word to describe this position? Geocentric is far too simple. Even the Jesuits recognize that God created the ENTIRE universe and all within it.

Perhaps thecabal can deign to share its knowledge of the entire universe, and its conviction that humans are the ONLY one HE has any interest in with we mere mortal humans. I’m sure that local...angels are curious too. BG.

“Among the billions of galaxies, nothing will match Earth.”

That is more a matter of faith and pride.

But we simply cannot prove it. Ever.


“We are alone.”

No. We are just on our own. And so are they.

There are other ‘intelligent life forms’ much closer to us, that we have yet to discover.

So, we are not as alone as we might think.

God isn’t what we think he is, and doesn’t think like we do.

So, if God has other ‘interests’, it’s not like we can do anything about it.

Heh, your pessimism in the face of facts to the contrary resembles that of a Democrat opposing progress in Iraq.

I thought that was Epsilon Iridani? Much closer to the Emperor. Ask Fleetlord Atvar.

Notice these points in his statement:

The discovery, they said, means that our solar system may be more typical of planetary systems across the universe than had been thought.

Neither of the two giant planets is a likely abode for life as we know it. But, Dr. Gaudi said, warm rocky planets — suitable for life — could exist undetected in the inner parts of the system.
“This could be a true solar system analogue,” he said.


They have found no warm rocky inner planets, therefore, no true analogue to our solar system.
When the technology is available to actually prove that there are warm rocky planets like those in our solar system, I will applaud the discovery. Until then, I will view it as another interesting find.
