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?- The Breakthrough Prize Foundation is aiming to shoot lasers at a light-propelled nanocraft that could reach Alpha Centauri in a few decades (instead of millennia). This lightsail spacecraft would have a mass of just a few grams, so it could be accelerated to speeds of 100 million miles per hour -- much faster than any existing spacecraft we've ever built (like Voyager I zipping away at about 38,500 mph).

- The Kepler space telescope has gotten plenty of headlines for finding thousands of exoplanets, but the far lesser-known TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) in Belgium is also finding some exoplanets, too. The TRAPPIST telescope is stuck on the ground (unlike KST), but it's looking at a few dozen ultracool dwarf stars and has found 3 planets orbiting a star that's just 0.05 percent as bright as our Sun.

- Kepler 36b and Kepler 36c are two exoplanets orbiting the same star which could possibly harbor some kind of microbial life (but probably not). Still, it's an interesting question whether or not life -- if it exists on either Kepler 36b or 36c -- could be transferred to its neighboring planet. (Though maybe we should focus on looking at Venus and Mars first....) [url]
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.

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

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