DailyDirt: Life On Other Planets
We've discovered thousands of exoplanets beyond our solar system, and some of them are even in the "Goldilocks zone" where liquid water could possibly exist. Some astronomers think life could be abundant in the universe, but there's not that much hard evidence (yet!). Here are just a few astronomical discoveries that might encourage researchers to look for signs of life a bit more carefully.- Exoplanets have been discovered circling some extremely old, metal-poor stars, creating interesting curiosities that might expand the theories of how planets form. These exoplanets might not harbor any kind of life... or we may want to get a bit more creative about how we envision life on other worlds. [url]
- A free-floating planet named CFBDSIR2149 is not orbiting a star, and it's only one of about two dozen or so known examples of a starless planet. This rogue planet is relatively young compared to the Earth, and some spectroscopic measurements suggest this planet's temperature is about 430° Celsius -- a bit too warm for our tastes (but maybe not for aliens?).

- Within our own solar system, NASA's Cassini spacecraft has detected spurts of water from Saturn's moon Enceladus. This evidence leads to some speculation of a habitable zone on some icy moons where microbes might be able to survive. [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.

Re:
Not that I think we shouldn't go searching for life elsewhere at all, but it may be for the best that we seem to be alone in the universe. I mean, looking at how mankind has turned out, what makes us think aliens would be any better? Gimme that Cowboy Bebop future instead.

Here is a brief excerpt.
Thinking in terms of what the ET's want is a mistake. Bottom line is there are several different races we're aware of, and they all have differing motivations, and some don't play well with each other.
I assume part of that briefing to be disinformation, but not all. The above I think are true. Can't say why other than it seems to make sense.

Not free floating planets
Space ships meant to carry the last of a race of peoples from a star that was going to die to a new home somewhere that was chosen for them!
(somebody should get the reference)

Re:
there is only a limited number of molecules that will make up DNA or something like DNA, these plants that have liquid water may be able to support life, but are the conditions suitable for the formation of life on those planets present ?
You need a 'primeval soup' with the necessary chemicals and chemical reactions, and large enough that statistically some will form into self replicating chemical entities (life).
Just having water alone, probably is enough to support life but not to create it.

Re:
So, it seems overwhelmingly likely that the briefing you attended, if it took place as you say, was 100% bullshit.

Huh?
From the TechDirt commentary above: "some spectroscopic measurements suggest this planet's temperature is about 430° Celsius".
There seems to be a bit of a contradiction here.
