If I have a wish, I will wish to know if there's life outside of milky way.

To those who doesn't know, the Universe is what we know as the biggest atmosphere. Within the Universe, there are god knows how many galaxies. Milky way is our galaxy. Earth is accompanied by other planets such as Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and I will still include Pluto.

Zillions of money spent on sending Spaceships and Voyagers to our neighbouring planets.
So far, technology brought humans to the Moon, ...that's all I know of. Venus is too hot thus a ship was sent and only survived for two hours in the lava. Even with our currently technology on the speed of spaceships, it takes 3-6 months to travel just to the Mars. Mars is closest to earth at 35 million miles and furthest at 250 million miles away.

Let me introduce the Astronomical Units
1 Astronomical Unit = 149 598 000 kilometers
The distance for Mars (from Earth) is currently at 1.005 AU. Neptune...is now 29.288 AU from Earth. You can do the calculations by google-ing 29.288AU.
Voyager 2 took 12 years to reach Neptune.

Now let me introduce to you LIGHT YEARs
1 light year = 9.4605284 × 1015 meters
Note...STARS that we see are FURTHER than our PLANETS. Antares was known as the biggest star visible to the naked eye. It is 1,108,430,000 km away.

What is bigger than Antares? You shall find out later at the end of the post. All of these planets, these stars and wonders are WITHIN our galaxy (Milky waay).

Let me see...nearest galaxy is Canis Major Dwarf Galaxy at 25,000 light years away. It is a natural satellite of Milky Way. In this case, satellite means it orbits the Milky way (ie: The moon is a natural satellite of Earth).

This is making me crazy. If there are any species coming to earth from the outerspace out of our milky way, who are we to call them aliens.....? If they can come to earth from so goddamn far away, I will follow them. If they exist, they are the smart ones. I'm the alien.

To those who thinks they are enjoying life to the fullest, this may not help. So, this is what I see tonight. Pretty damn small, eh? I feel like crying.

I love how the Universe is killing me softly.

looking at the size of the Universe... I wont be surprise if there is Life out there...

Probably only then will humanity appreciate our only Home and a sense of unity by seeing each other as Earthlings rather than Chinese or Taiwanese, Palestinian or Israeli, Christian or Muslim... and closer to home bumi or non-bumis.

hmm... this comment nothing to do with Astronomy.. :p

I do believe that there is life out there, but I also believe that at this point, there is no relevance if we could confirm it.

The distance is just too vast. It is near impossible to imagine distances measured in something in light years. Here's a simple perspective, the circumference of the earth is about 40,000 km. To travel a light year, you would have to go around the earth more than say 200 million times, and the nearest start to us is about 4 light years away. Seriously, can you really imagine that ?

Second of all, we as a species/civilisation don't really deserve to be noticed. Humanity is really a sorry excuse for an existence. I believe that if some other life did manage to discover us, they will probably manage a scoff at us before flying on by.

And yea, we are barely a twinkle in the night sky. Comforting, no ? =P

Same with religion. Except that some truth about existence of outer life may be hidden. We don't know.
