Quote HistoryQuoted: This is related to this post. One way we could possibly find indirect evidence of life on an exoplanet is by doing spectroscopy on it's atmosphere. Diatomic oxygen is exceedingly rare in the universe. Pretty much the only way for it to be in high concentrations in a planet's atmosphere is from lifeforms producing it in mass. The way we can detect that oxygen is by taking a spectrum of the light coming from a star while an exoplanet is in front of it and look for absorption lines in the light that passed through the planets atmosphere. We can also do this for bodies in our own solar system when they pass in front of a large star. http://asd.gsfc.nasa.gov/blueshift/wp-content/uploads/2014/12/10329033583_475b14a19c_o.jpg http://i0.wp.com/www.universetoday.com/wp-content/uploads/2010/02/isolating-a-plaents-spectrum.jpg?resize=510%2C408 |

I'm guessing that only light that's passes through the atmosphere of an exoplanet reaches us...
If we are detecting them by the "wink" as they pass in front of the star then we know at that exact moment all the light reaching us went through the atmosphere... I'm guessing but I'd think that is most likely what makes it possible.. |

Because people are so much better then computers at pattern recognition having the masses help sort through the data makes a lot of sense. |

To add some more fun stuff. This site can help you find orbiting satellites so you can see them on your own as they pass over your location. With binoculars you can make out the shape of the ISS on the good passes and almost always see the gold color rejected off the solar arrays. A few years back I lucked into a seeing a triple pass. The ISS, chased by Atlantis which was chased by the ESA Jules Verne HTV. All three in a row crossing the sky at 17,800 MPH. Heavens Above This site can help you navigate your mind around the sky and find really cool things to observe all on your own. You will never see the colorful pics posted here, using your eyes but you can see things like the ORION nebula easily and see the clouds that are forming stars right now as I type this post. I am always in awe when I look up. Skymaps I am not an astronomer, but I did take two years in college. By far it was my favorite course of study, I just can't feed my family using the knowledge. If you plug your coordinates into Heavens Above, then save, you'll return to your site specific info every time.

Any further reading material on this? Keep in mind that the 14.7 billion is to the electromagnetic spectrum horizon. Beyond that we just don't know. And yes, those objects at the edge of detection where there 14.7 billion years ago and have since continued on at an logarithmic pace. They are much father that the 14.7 billion ly that we detect them at right now. If you where to move 5 billion ly from the earth and observe you would still detect out to around the 14.7 billion ly limit we currently have, only the view would be different and you would observe things we can't observe right now. We don't know if the universe is infinite or finite at this time, we just know how far out we can detect/observe. Nothing is moving faster than c, just not gonna happen. Time and distance are the issue. Those far objects have continued to move over the time since they emitted the photons we are detecting now. |
