ancient planet found
http://science.nasa.gov/headlines/y2..._psrplanet.htm
thats nice and exciting to hear. However, if there was intelligent life on it that would've given the aliens 13B years to settle the galaxy, perhaps even our own solar system. Surely, they would've found a way to travel at or close to the speed of light. We simply see no signs of them or their legacy. No probes, no radio transmissions, no visitations. In fact, if there was any intelligent life in this or in any other galaxy, 15B years is long enough for perhaps millions of them to roam the universe and leave signs saying "I wuz here". |

I have often had the same thought. We should be finding alien beer cans and cigarette butts all over the place. Then the Devil's Advocate on my shoulder jumps up and reminds me that we can't compare other civilizations to ours. For all we know, they have cleaned up there remains, because we can't handle the truth. BV. |

i love it...they estimate it is 13 billion yrs old....which is what "experts"
now claim is the age of the universe.....so it was created in the big bang??? i think not.....this is more ammunition for us who say fred hoyle was right and it was formed in a previous cycle or oscillation....art swanson |

The Universe could and probably is much older then this, it's just that our current capabilities only allow us to see up to that 13-15 billion mark. So if they did find a planet that is 13-15 billion, it still fits in with current models. BV. |

The problem with us simple earth creatures is that we look at things in terms of what we currently understand. if we land on Mars and discover worms it would be very exciting. It was exciting to find stone age people in Africa and Asia. Why wouldnt aliens 13Billions years more advanced than us be excited about finding a species possessing space flight, nuclear weapons, radio, and Pam Anderson? WHY AINT THEY HERE? |

My question is that we see something that is 13-15 billion light years away.
That means it took 13-15 billion light years for the light from that object to reach our grasp. Who to say there isnt something that is 20-or more billion light years away whose light has not yet reached our grasp and won't for another 5 to 7 billion light years or until we are able to gather more light. We tend to think that our limitations to gather light from the greatest distances sets the standard for the universes age, but our limitations have nothing to do with what is reality. In a few years as our technology increases as does our ability to gather light or infrared imagery then all of the sudden the age of the universe increases, but the age of the universe hasn't increased much just our technology has... Does this make much sense? just my thoughts and no I'm not stoned! :0) "BenignVanilla" wrote in message ...

It shows what a great telescope the Hubble is I knew it was
good,but to pick out a planet some 12 billion light years away is amazing. PBS had an astronomer discussing this ancient planet,but I missed most of what he had to say. Seems the planet was part of a binary system,and the planet was bigger than Jupiter. I can't imagine the Hubble picking out Binary systems at such great distances. Bert |

From what I've read, the planet is just 5,600 Light Years away - but that
doesn't make the Hubble any less of an achievement. If only the mirror had been made correctly in the first place so they didn't have to remove a the promising Faint Object Camera and some other bits. "G=EMC^2 Glazier" wrote in message ...

Bert once again posted more incorrect stuff:

It is 5,600 light years away in the globular cluster M4. -- David W.

Does this make much sense? just my thoughts and no I'm not stoned! :0) We've already seen back as far as can be seen; WMAP has imaged the surface of last scattering of the early universe, before which it is entirely opaque. More than just imaging the furthest objects is involved in dating the universe. Given what we do see, a backwards extrapolation of the motions of it all has the whole lot coming together to a single spot some 13.5 billion years in the past. Even so, there's little doubt that there exists more of the universe beyond our little 13.5 billion light year horizon. In fact, it is thought that the universe is immensly larger than our little observable patch. But it is also true that we should never be able to see it. You see, as the universe expands, the further away things are the faster they are receeding. At some given distance, the rate at which things recede equals and then exceed the speed of light. Any light emitted by objects beyond that radius can never reach us. |
