Simulation Says Extremophiles Could Survive on Europa's Surface - Polidicks

[RELEASE] Extremophiles Survive Simulated Conditions on Europa Astrobiologists have reproduced the conditions on the surface of Europa and found that some extremophiles survive kfc 10/03/2011 A couple of weeks of ago, we looked at a study indicating that in Earth ejecta is more likely to end up in the Jovian system than on Mars, at least in some scenarios. That raised the possibility that life from Earth could have made its way to places like the Jovian moon Europa, which astronomers believe has a large salt water ocean beneath its icy crust. But this would only possible if terrestrial bugs can survive the intense vacuum and radiation in interplanetary space. Astrobiologists have studied the way many creatures survive in a space-like conditions. They've looked at bacteria, fungi, viruses and even biomolecules such as DNA. Some lucky bugs have even survived the journey to the Moon and back. But one branch of life has been largely ignored in these tests--archae. That's surprising since these bacteria-like bugs often flourish in extreme conditions on Earth. Today, Ximena Abrevaya at the Universidad de Buenos Aires in Argentina and a few pals go some way to righting this wrong. These guys created a vacuum similar to that which exists on the surface of Europa. They then placed three organisms in it: the salt-loving archae Natrialba magadii and Haloferax volcanii and the radiation-resistant bacteria Deinococcus radiodurans. They then bombarded these creatures with the levels of ultraviolet radiation that might occur on the surface of Europa and waited to see what happened. None of Haloferax volcanii survived. But small amounts of both Natrialba magadii and Deinococcus radiodurans did. That's interesting because Deinococcus radiodurans is well known as one of the hardiest organisms on the planet. Numerous experiments have shown that it can survive levels of radiation, vacuum, acidity, cold and dehydration that would kill almost everything else. For that reason, Deinococcus radiodurans has always been a candidate for seeding life elsewhere in the Solar System. But now it looks as if it would have a companion on such a journey in the form of Natrialba magadii, an organism only isolated from the salty waters of Lake Magadi in Kenya in 1984. Before getting too excited, however, it's important to note that these experiments have a weakness: the tests lasted only for three hours. That's not long compared to interplanetary journey times: Earth ejecta takes tens of thousands of years to reach other bodies. However, the journey on a spacecraft from Earth would be much shorter, just a few years. So if Abrevaya and co's experiment tells us anything, it's the importance of sterilising spacecraft before they leave here. It's just possible that right now, small colonies of Deinococcus radiodurans and Natrialba magadii are flourishing in the weak sunshine and cool wind around Viking 1 and 2.

LET'S GO FIND THEM [editline]21st November 2011[/editline] FUCK I LOVE SCIENCE

Extremophiles.. Do they like.. enjoy extreme sex or something? In that case, send me to Europa!

[b][i]YES![/i][/b]

[QUOTE=Runar;33376694]Extremophiles.. Do they like.. enjoy extreme sex or something? In that case, send me to Europa![/QUOTE] Extremophiles bear that name since they live, well, in extreme locations. Like in really hot or, in this case, cold places. But still, science! Edit: Also I guess you could call having sex on a really cold moon or in a really hot volcano pretty extreme.

Eudoxia, would a SpaceX craft be able to deliver a significant payload to Europa? Say some sort of drilling rig and a heavy probe?

[QUOTE=Runar;33376694]Extremophiles.. Do they like.. enjoy extreme sex or something? In that case, send me to Europa![/QUOTE] A "phile" is like a love of something, e.g Pedo = Children, Pedophile = Lover of Children or somthing like that. So extremophile means Lover of Extreme?

aliens, my nigga.

[QUOTE=geoface;33376757]A "phile" is like a love of something, e.g Pedo = Children, Pedophile = Lover of Children or somthing like that. So extremophile means Lover of Extreme?[/QUOTE] Organisms that can survive and thrive in extreme conditions that would otherwise be deadly.

One hundred million years from now the race of creatures that evolved under the harsh conditions on Europa will return to earth to take it over. [editline]22nd November 2011[/editline] [B]Don't do it![/B]

um no shit?

Expected find: Nothing Amazing find: Alien life Unbelievable find that would turn everything we know about ourselves on its head: A type of life also found on Earth

[QUOTE=Zeke129;33376801]Expected find: Nothing Amazing find: Alien life Unbelievable find that would turn everything we know about ourselves on its head: A type of life also found on Earth[/QUOTE] Holy shit if they found that third thing everything as we know it...

[QUOTE=Zeke129;33376801]Expected find: Nothing Amazing find: Alien life Unbelievable find that would turn everything we know about ourselves on its head: A type of life also found on Earth[/QUOTE] god damn it now I'm all excited thinking about the third option despite the fact it's ridiculously unlikely

I live in Europa. Am i an extremophile?

[QUOTE=Turnips5;33376834]god damn it now I'm all excited thinking about the third option despite the fact it's ridiculously unlikely[/QUOTE] The third option would reinforce Scientology.

someone buy eudoxia the [u][b]SCIENCE GUY!!![/b][/u] title

[QUOTE=Zeke129;33376801]Expected find: Nothing Amazing find: Alien life Unbelievable find that would turn everything we know about ourselves on its head: A type of life also found on Earth[/QUOTE] Given the living conditions we often find things living in here on earth in the ocean, I honestly would not be surprised to find at least single celled organisms living on Europa. Just 20 years ago we thought the ocean floor was lifeless. Today it's an important ecosystem of various organisms, some of which survive temperatures over 300 degrees Celsius. There's no doubt in my mind that if Europa -which is still a relatively young body- has undergone the process necessary for life to begin, will have life on it.

Or are organisms that small impossible to differentiate?

[quote]It's just possible that right now, small colonies of Deinococcus radiodurans and Natrialba magadii are flourishing in the weak sunshine and cool wind around Viking 1 and 2. [/quote] So there's a good chance there's life on Mars. Stuff we brought to it. :v:

A feat like that requires the work of several nations, or a company/agency with a very large budget. Here's a proposed mission involving Europe, USA, Russia and Japan, but it was put on ice due to NASA's budget. [url]http://en.wikipedia.org/wiki/EJSM/Laplace[/url]

Or are organisms that small impossible to differentiate?[/QUOTE] Finding something exactly like it is on earth would be mind blowing. What we would probably look for is if the organism had DNA similar to ours. If we found that, it may support the idea that we were seeded by comets. If we find organisms that are completely different than organisms here, but still have the same DNA, then that will really force us to question our own origins.

Even if they did die after 3 hours, maybe they are fast motherfuckers, and mate, then give birth in that amount of time. Hey, it's aliens anything is possible.

Thought this was about sending in dudes with a fetish for surviving in extreme environments to Europa

Fuck alien life, we got things to bomb! We should just transfer %70 of the military budget over to NASA.

Oh and money of course.

Fuck, ai thought the tea party wants to expand to Europe. This is way better :v:

IT's like that ant-arctic primordial ooze they found, the Russians want to use Kerosene as a lube for their drill but it is likely that it will contaminate the life that has been living there undisturbed for years. Even the possible radioactive drill which heats the drill melting it through ice is a dangerous alternative.

hey ho, let's go to the motherfuckin' moon~
