Found planet in "habitable zone" where the elements for life as we know it could live, albeit on a diet?

Earth-like planet found that may support life

quote:
Astronomers claim to have discovered, for the first time, an Earth-like planet outside our solar system that could support water -- and potentially life.

Researchers have not directly seen the planet and it will be years before more sensitive instruments will be developed to look for signs of life on the planet that is about 190 trillion kilometres away from Earth.

But according to measurements, the planet is about 50 per cent larger and five times heavier than Earth. It orbits Gliese 581 -- a diminutive "red dwarf" star located in the constellation Libra.

Other details of the new planet:

  • It orbits its star every 13 days.
  • t circles its star 14 times closer than the Earth orbits the sun.
  • Gravity is 1.6 times as strong as the Earth's -- so a 150-pound person would feel like 240 pounds on 581 C.
  • Astronomers previously found a Neptune-sized planet circling the star Gliese 581, as well as evidence of a third planet about eight times the mass of Earth.


Search for life is next, researcher says

quote:
Swiss scientist Michel Mayor, who heads the European team that announced the discovery of a new potentially habitable planet, has his sights set on an even bigger target — detecting signs of extraterrestrial life.

Mayor predicts that top researchers are less than two decades away from being able to detect real signs of such life — if it exists.

"There's only one thing we can do. We can do science, we can do experiments. We have the methodology, the ability to do this simply on science, so let's do it," the University of Geneva scientist said Wednesday.

That's one short 'year' ... I wonder how that affects things. And the probability that the planet has one face towards it's sun (like our moon).

Enjoy

I'd want to send a very sterile probe first to send back images and other data -- see if life is already there without need of seed from here.

If there is then I'd want to know how that planet differed and how it was the same as ours, what the life was like, and if there was any way to see how IT originated.

That could take a lifetime ...

Re: Howdy Neighbor!
What about another pioneer probe to go by some planets not yet visited and then with an ultimate destination?

I'd expect to have some information before such was ready from analysis of atmosphere etc.

We'd also be able to run a check on that acceleration anomaly issue with a properly designed and calibrated satellite.

Lots of good information.

Re: Life? If so, abiogensis or panspermia?
It could also turn out to be based on amino acids similar to what we have here, but still not be the same DNA style life ... perhaps never getting past RNA replication?

sorry for not explaining the numbers... but... a scientist did research on what makes up other material such as atoms to molicules... and the research was that if all of those material can accidentaly create life and sustain it is 10 to the pwoer of 40,000 and you get the rest...

See the old improbable probability problem thread, message 44

You'll be on topic there.

Welcome to the fray.

Enjoy.

Re: RE; You are uninformed
Publisher: Philosophical Library (New York) (January 19, 1984)

Surprisingly a lot has happened in the last 25 years.

Amazon.com review

quote:
A seminal work for the theory of intelligent design, this book provides a scientific critique of the prevailing paradigmatic theories of chemical evolution. The authors include Discovery fellows Charles Thaxton and Walter Bradley, and they conclude that the prebiotic soup from which the first cell supposedly arose is a myth. The Miller-Urey experiments employed an unrealistic gas mixture, and there is no geological evidence for its existence in Earth's distant past. The "soup" faces a myriad of other problems, such as inevitable rapid destruction at the hands of radiation.

In other words, the book is out-of-date hogwash. Strangely, I doubt that it goes anywhere useful or even half-way valid.

Care to comment on why you think this book has any real value?

Enjoy.

Possibilities with other chemicals
Welcome to the fray, cervical.

Does anyone have any thoughts of non-carbon based life?

There are other chemicals that can form similar but different compounds, and those differences could be enough different to prevent life. One of the problems is distribution and another is the forming of the more complex molecules. Carbon has an advantage in that there are a number of space born compounds that are "pre-biotic" - almost what we call "organic" molecules because they are found in (gasp) organisms.

Do a google search on "PAH Space" -- with "I feel lucky" I got

http://www.astrochem.org/PANHS.html

This can jump-start carbon based life, while other compounds don't have that advantage.

Why should life need water?

Life needs lubrication and flexibility for movement, multicellular life need a transport medium, and it helps to have a compound with a slight electrical bias to dissolve compounds.

Enjoy.

Re: RE; You are uninformed
Hi Scoff, nice to see you again.

  • It orbits its star every 13 days.
  • It circles its star 14 times closer than the Earth orbits the sun.
  • Gravity is 1.6 times as strong as the Earth's -- so a 150-pound person would feel like 240 pounds on 581 C.
  • Astronomers previously found a Neptune-sized planet circling the star Gliese 581, as well as evidence of a third planet about eight times the mass of Earth.
  • Yeah, not necessarily out of the zone, but still rather alien for life we know. It might not make much difference to waterborn life.

    Enjoy

    BTW, if you get a chance, please contact me at my old Netscape email address (don't forget the numbers 0165). I tried to send one to your old address, but it got sent back.

    click on "to share" in the sig and my email addy is listed. I don't use netscape anymore, and AOL finally dissed the old netscape board and the website they had hosted (and promised to let you keep).
