All of Life’s Ingredients Found in Orion Nebula | Wired Science | Wired.com
Very cool stuff!
Awesome! My hopes of alien-lifeforms, sentient or not, existing grow more and more. What a day in human history it will be when we come across another alien life form. Just hoping it doesn't end up like what happened in The Andromeda Strain lol.
Definitely bringing this to my Astronomy Class tomorrow.
Funny that the image is 1300 years old since it is 1300 LY away
So if we sent a radio signal that they can read it would take about 1300 to reach and 1300 years to come so finding aliens might take awhile lol
Nice! About time we see some aliens
Crap forgot about that. C=3.0X10^5 km/sec
What the hell is taking the human race so long to advance?
People have so little comprehension of the sheer hugeitude of space.
Let's look at what we found out here. We find the chemicals we find in life here at a distance that takes light 1300 years to travel.
There's so little actual clumps of matter we can use or explore out there compared to what we incorrectly term "vacuum". There are no stops, no places to refuel, once we leave the solar system we better be totally self-sufficient for years or there's no hope.
Look at it this way, even jogging over to Alpha Centauri, which has 3 potential stars with worlds around them, takes light over 4 years to make the trip. At 1/10C that's 40 years just to get there. A round trip is effectively impossible for any human to survive.
Even moving at near C, we're screwed in terms of distance and time. If we cannot eventually figure out a way to "cheat" around the lightspeed limit on matter (and a few theoretical propulsion ideas are being floated) we are stuck in Sol system forever unless we wanna gamble on flinging generation or sleepships out and hoping for the best.
will they just talk to us already?!
Its not surprising really. Its crazy to think we are alone. Space is HUGE.
I can only hope that if we end up finding anything, they turn out to be hostel.
Oh c'mon, you KNOW you want it to happen.
"The greatest possible sign of other intelligent life in the universe is that none of it has tried to contact us."
Well, we're really just babies at this point and have only been in existence for a miniscule fraction of geological time. That said, if you look back over the past 100 years or so, it seems we're actually advancing fairly rapidly.
If you extend human qualities to intelligent extraterrestrial life, then a hostile encounter is a always a possibility. Hawking made a passing remark to that effect, saying that extraterrestrial life meeting human civilization could be analogous to Columbus and his rather disastrous encounter with natives. (From their viewpoint, at least.) Looking at humanity's deplorable treatment of other life (both human and non-human) on Earth, it definitely doesn't make me very comfortable about meeting extraterrestrial intelligence from another planet.
you know what we can really use? TFA space bridges
Saying that just finding these ingredients is an indication of life, especially in something as large as a nebula, with unstated concentrations, is like saying that a campfire is an indication of finding a finely crafted diamond necklace, because the trace ingredients are found to be present. Those chemicals would have to come together in the exact right way for life to exist at all, let alone in a form we coul recognize.
Furthermore, there's plenty of other peaks in the spectrum of that nebula, meaning there's a ton of other "ingredients" in the mix, many of which would likely hinder the appearance of life.
Also, nebulae are pretty much known for having high levels of ionized hydrogen and various types of radiation. Not the best conditions for life to thrive in.
This is a pretty short article, so maybe there's more to it than what's been written, but I don't think what's here proves things one way or another at all. Pretty amazing they can use emissive spectroscopy so precisely on something that far away though..
I want a f**king spacesuit. With jetpacks, unlimited food & water generators & unlimited oxygen.
Also, this entire universe can be a particle of dust stuck in the foot of a giant, so why bother?
Earth may be just what you're looking for, though the unlimited part has a few catches.
It is possible for organisms to adapt to high levels of radiation. Cockroaches for example can survive extreme levels of radiation.
Alien life could evolve differently than Earth's organisms. One can wonder...
True, cockroaches and most chitinous invertibrates can survive relatively high levels of radiation, but its not like they're impervious to it. Simpler lifeforms, especially single-celled ones, are not nearly as resistant to the same bands of radiation, and unfortunately, as we understand it, that's how life starts out. Earth's atmosphere filters out tons of radiation, so its possible that if there was a planet in a nebula with similar shielding, that it could serve as a sort of safe haven, but then we're right back to the other two points I mentioned.
Its entirely possible life, even intelligent life, could evolve in a completely different and counterintuitive manner from us, but we've still seen no evidence for it at this point.
True and true.
Do you think it's possible that a lifeform could exist as a different element? Take for example every organism on the planet Earth. We're all carbon-based life forms. What if, somehow, a lifeform evolved from a different element?
I got the idea from that SciFi Comedy Evolution. Just out of curiousity. This stuff is very interesting
I hope I will be alive when we contact the aliens.
