content: How do all the nopes fit on that tiny blob?It's so indistinct I can't really be sure it's actually Australia, or if it's right way up. Looks like it might be, which is nice.

content: It is lacking a bit of detail - but at that distance, I suppose we can't betooooooocritical.It would seem Australia is there ... and upright. Time of day is sunset for Western Australia. The apparent axis tilt looks right for a Southern Hemisphere summer. The blooming white blob at the bottom would obviously be Antarctica. Not sure about the other blob - possibly cloud.

content: In the whole scheme of things our planet and the people in it are insignificant. Are we alone?When I was young, I believed in UFOs and the stories from the infamous fraud George Adamski, and Barney and Betty Hill. Today, There is zero reason to believe there is any intelligent life on other planets, as there is absolutely no credible evidence whatsoever. No intelligible radio signals ever have been received from outer space. It suggests we are indeed alone - certainly with the resource and ability to generate intelligible radio signals.

content: Quote from: VK3DRB on January 09, 2017, 12:14:31 pmOn the contrary, a lack of evidence doesn't necessarily mean what people think it does. Since astronomy (particularly radio astronomy) was discovered, we've still only observed a miniscule amount of the universe. I make the suggestion that statistically speaking we are not the only intelligent life in the universe. Sure, life on Earth might have happened completely by chance but Earth is 'only' ~4.5 billion years old and our technological limitiations prevent us from finding others. I think it's far more likely we haven't found intelligent life because we can't observe that far yet or whatever intelligent life there was in the observable universe no longer exists.I don't believe in UFOs or alien creatures visiting Earth, but to say we're the only ones special enough to have survived out there? I think that's unlikely.This imagemight help put our "insignificance" into perspective.Fantastic photo by the way!

content: We still don't know if life is a common occurrence yet.If it is, under the right conditions, then there is a fair chance that there is life somewhere else.The possibility of encountering aliens though, considering the vastness of the universe and the relatively slow speed of light, is pretty remote.

content: Quote from: Halcyon on January 09, 2017, 06:53:08 pmStatistically speaking, yes, we are likely not the only intelligent life form in the universe.But, if the model of expansion of space is correct, the assumed size of the universe is irrelevant for contemplating the chances of meeting/communicating with them. Even the size of the observable universe (~28.5 Gpc in diameter) would be irrelevant for such contemplation.You could basically restrict your hopes for ever communicating with alien lifeforms to the cosmic "neighborhood" within the Hubble radius (~4.5 Gpc). Anything beyond the Hubble radius recedes from us with a speed faster than light, making it likely impossible for alien lifeforms in galaxies so far, far away to ever contact us or visa versa. (Again, this is under the assumption the estimated rate of expansion is more or less correct, and does not reverse in the  future.)
