DailyDirt: All Alone In The Universe With Nowhere To Go...

from the urls-we-dig-up dept

People have been looking up into the sky for centuries, wondering what's out there and if we're alone on this world. Astronomers, more recently, have been looking into deep space with some relatively high-tech equipment -- finding some strangely inexplicable phenomena (that could be alien megastructures?!) and still wondering if we're alone in the universe. We may never know for sure if intelligent life exists anywhere else, but it doesn't hurt to look, does it? After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

    "The Breakthrough Prize Foundation is aiming to shoot lasers at a light-propelled nanocraft that could reach Alpha Centauri"

    Now if only we could capture some space sharks to mount lasers on...

      Re:

      This project makes no sense at all. Even if it works, it does nothing useful. It's too small to hold a transmitter to send back any data, and there's no way for it to turn around...

      For that matter, all it would do is fly past Alpha Centauri at 100 million mph. The only thing this craft would do is be a menace to anyone else along the path it follows.

    The TRAPPIST Project

    Small red-dwarf stars probably outnumber other kinds of stars, including our Sun. Trouble is, being so dim, they’re much harder to see.

    Also, being so dim, their “goldilocks zone” (the region in which water could exist in liquid form on a planetary surface) is much closer in.

    On the bright side (so to speak), this means that, if they have planets similar in mass and (probable) surface temperature to our Earth, they are much easier to spot, for 2 reasons:

    • Proportionately greater perturbation on the orbit of a smaller-mass star
    • Even greater perturbation because they are closer to the star.


    Which makes you wonder why they didn’t start searching for planets around such stars sooner...

      Re: The TRAPPIST Project

      ...because, as you just pointed out, they're much harder to see? (I don't actually know anything about the subject, but that seems like an obvious reason.)
