DailyDirt: All Kinds Of Bugs Living In Outer Space?

from the urls-we-dig-up dept

Panspermia isn't a crazy idea, especially when we seem to keep finding extremophiles that can survive in very harsh environments. The components of life may be traveling between planets or solar systems at a non-zero rate, seeding the universe with living materials. That said, life is still relatively fragile, but there may be some optimism in finding living specimens elsewhere than Earth. (First, though, we have to make sure we're not the ones contaminating our own solar system.) Here are just a few links on various organisms that might survive a trip in space -- without a space ship. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Space is vast. Even with gravity pulling stuff in, I'm not sure microbial life could span multiple solar systems, just because of the sheer distance involved. What are the odds that something traveling out of a solar system at a random trajectory will actually hit any other solar system in any reasonable time frame? (And since hitting a sun obviously isn't going to work, it will somehow have to hit something in that system that *isn't* the largest object with the most gravity.)

    And sure, some spores can survive 18 months in space. That's fine for getting to or from Mars. But does that translate to surviving the centuries or millennia it would take to actually get to another solar system on something that doesn't have propulsion? And does that translate to surviving an uncontrolled reentry?
