    Study: Earth-Like Planets Closer Than Expected
    February 06, 2013 - Astronomers say there could be as many as 4.5 billion Earth-like planets orbiting stars in the Milky Way galaxy, and the nearest of them could be practically next door, in cosmic terms.

    Comets found in extrasolar systems etc goes the article, then the author states ; "Welsh said that if, as experts theorize, comets could have seeded the primordial earth with organic carbon material and water, then comets also may be the key to life elsewhere in the universe. “If comets are universally distributed around, then you could say that the incidence of life could be higher on other planets than we ever thought.” Not too long ago the science community would have scoffed at the idea that comets could have seeded life. I think its possible with all the carbon and organics in space, vast clouds of the precursers needed for life are common. However even though I beleive life exists elsewere in the universe the problems associated with how life began are just pushed farther back in time. I feel life was created of course. DNA is simply too complex, too structrued, and most importantly DNA contains 'code' which does not happen in nature, Or if the did there is not enough time since the universe began (if our universe is only around 14b years old) to create a simple code much less someting like the code in DNA. By Codes I don't mean patterns like snowflakes and other fractals, but rather symbolic codes such as music, blueprints, languages, computer programs, and DNA. So where is the desinger. In the case of life arising in the universe an intelligent designer or 'god did it' is a credible idea.

    Seems sad about Herschel, but all the orbiting observatories have limited lives, don't they?

    They should maybe have a contest for someone to come up with a practical use for it.

    learning


    for example, H, O, C (elements) are all throughout the solar wind

    that means, the basis of life is all throughout the universe.

    Learning with basic common sense, makes them claims.... "stupid easy"

    Comet of the Century' Already May Have Fizzled Out
    July 29, 2013 — Astronomers slated to meet this week to discuss observing plans for Comet ISON may not have much to talk about. The so-called “Comet of the Century” may already have fizzled out.

    Ancient star helps scientists understand universe's origins
    February 9, 2014 - Australian astronomers have found the oldest known star in the universe, a discovery that may help to resolve a long-standing discrepancy between observations and predictions of the Big Bang billions of years ago.

    I'm thinking 'our' universe needs a proper name since we probably cannot exist in nothingness...perhaps hundreds/thousands? more universes share infinite space with us? I vote for Hal...

    Tip: Clean those 'throw aways' and put a thin film of oil on them, they'll last a long time.

    Ok, but I dont have any body hair to shave, so I dont have razor blades.

    I heard tho that at one time people thought pyramids would sharpen razor blades, that is why I mentioned it.

    Thanks anyway!

    But how would oil sharpen it..?http://emtrix.dbs.umt.edu/virtual-microscopy/razor-used/razor-used-02.jpg

    Doesn't sharpen it, keeps it from corroding (which dulls the edge) after use.

    Astronomers Capture 3D Images of Mysterious Intergalactic Matter
    April 30th, 2014 ~ For the first time, 3D images have been captured of a cosmological entity called the intergalactic medium (IGM). Until now, the structure of IGM had been theoretical. The discovery could provide astronomers with a new understanding of galactic and intergalactic dynamics.

    The rotational speed of planets will be different for every planet in every galaxy...on Earth it is ~24 hours and on Beta Pictoris b it is ~8 hours. Further, Earth's trip around it's star takes ~365 days or what we refer to as 'one year'. It's interesting to me that our concept of 24 hour days and 365 days per year is a metric that only works on Earth. Time as we know it on Earth will be completely meaningless on Beta Pictoris b and all other planets. So is 'time' just a fabrication/creation of society...like a language? Or is there a more 'universal' time measurement that we should adopt...

    You teaser! Do you know one of the biggest downsides of being a Christian? To practice what I preach i.e. doing our best to live by the teachings of Jesus I cant care if I must anger one of the few females that post here at PF. Hey where are all the christian girls? I know they are everywhere in the real world but are rare on these message boards.
