We are not alone

This collection of galaxy specimens, taken by NASA's Wide-field Infrared Survey Explorer, or WISE, mission is pictured and released by NASA May 25, 2011.

It showcases galaxies of several types, from elegant grand design spirals to more patchy flocculent spirals. Some of the galaxies have roundish centers, while others have elongated central bars.

The orientation of the galaxies varies as well, with some seeming to peer straight back at us in the face-on configuration while others point to the side, appearing edge-on. Infrared light has been translated into colors we see with our eyes, such that the shortest wavelengths are blue and the longest are red.

The oldest stars appear blue, while pockets of newly formed stars have yellow or reddish hues.

how is it relevant and where does it say that life has been found on these galaxies?
Stop starting threads just for the heck of it
 
quite the title of the old TV serials xfile,

i want to believe.
 
we will never know if we are not alone, but when im alone ill have my hands on spanky.
 
I'll surprised if we're the only intelligent living species in this universe.
 
Well it is highly impossible to believe we are alone. As we know even our Universe is not the only one and many more hundreds and thousands of them next to it. If the whole universe itself is that huge which is not even put on a paper or computer for the sake of calculating it( because one cant even imagine how big it is).

My strong belief is that there might be some other civilisations. Be either developed than compared to us or underveloped. And when we say that they are developed than us, many ask then why no alien interaction so far? Atleast as an initiative by the other side which if a hihgly developed one, then it might have been a leader in advanced time warp and wave warping technologies......
Well lets put those sci-fi thinking to rest and lets simply wait and see. sort of like Innocent until found guilty. :P
 
You mean this .......

An extraterrestrial bacteria ( alleged ) and a normal bacteria side by side ...

Not m not a biological expert here, but you have to consider many things while coming into some conclusions. like carbon dating to verify the age of the meteorite and the microbial life, the temperature its exposed to while entering the earth's atmosphere, chemical composition of the organism, etc.

I think scientists examined all those factors before coming to any conclusions.

In what's sure to rekindle the debate over the question of life beyond Earth, a scientist at NASA's Marshall Space Flight Center says he has fossil evidence of bacterial life inside of a rare class of meteorites .

Writing in the March edition of the Journal of Cosmology, Richard B. Hoover argues that an examination of a collection of 9 meteorites - called CI1 carbonaceous meteorites - contain "indigenous fossils" of bacterial life.

"The complex filaments found embedded in the CI1 carbonaceous meteorites represent the remains of indigenous microfossils of cyanobacteria," according to Hoover.

That matter-of-fact sentence also underscores the shout-out-loud implication that the detection of fossils of cyanobacteria in the CI1 meteorites raises the possibility of life on comets. And Hoover does not shy away from offering that very conclusion.

Skeptics will doubtless weigh in soon with questions. Still, Hoover's proposition may have stirred more controversy several years ago. More recently, though, some scientists have suggested that meteors and comets slamming into the Earth brought with them the very integuments of life, including water and a host of complex organic chemicals.

If he's right, Hoover may have evidence to support that theory. He argues that the complex filaments he found embedded in the meteors are micro-fossils of extraterrestrial life forms that existed on the meteorites a long time ago prior to the meteorites' entry into the Earth's atmosphere.

"This finding has direct implications to the distribution of life in the Cosmos and the possibility of microbial life on in liquid water regimes of cometary nuclei as the travel within the orbit of Mars and in icy moons with liquid water oceans such as Europa and Enceladus," he writes.

In an accompanying comment, Rudy Schild, the journal's editor-in-chief and a member of the Harvard-Smithsonian's Center for Astrophysics, announced that the publication has sent out a "general invitation" to more than 5000 scientists to review the paper.
"We believe the best way to advance science, is to promote debate and discussion," he wrote.

Is it discovered that there are animals in other planets? If no than we are alone as of now. I will not consider some bacteria, virus or amoeba as life.

Lol, why?

What's the definition of life for you?
