విశ్వం లో మన స్థానం ఎక్కడ ????????????

Planet Earth - our home
The Universe

Our solar system - "Sol"

The distance between the Earth and the moon (to scale)

Amazingly, we can fit all of the planets in the solar system in that distance...

The size of North America, to scale with Jupiter

The length of Saturan's rings is six times the size of Earth...

If Earth had rings like Saturn, this is how the sky would look like in different parts of the world:

You may have heard that the European Sapce Agency landed a probe called 'Rosetta' on the Churyumov–Gerasimenko comet. This is that comet, to scale with Los Angeles:

The size of the Sun compared to the rest of the planets:

The Earth, as seen from our moon - Luna:

And this is what the Earth looks like from Mars:

And that little blue dot is us, as seen from Saturn's orbit:

That tiny little speck is the Earth, as seen from 4 billion miles away...

Remember the size of Earth, compared to the sun?
The Universe

This is what a sunrise looks like on Mars:

As huge as the sun is, in the universal scale - it's actually tiny. When put next to YV Canis Majoris (one of the largest known stars), it seems smaller than a speck of dust. YV Canis Majoris is 1419 times bigger than the sun!

Now see how small the Earth is compared to it:
The Universe

If you want another scale, imagine the sun is the size of a human white blood cell. Now, staying on that scale - the Milky Way galaxy would be the size of the United States - that's almost incomprehensible.
The Universe

And if you ever wondered - this is where our solar system is in the Milky Way:
The Universe

Despite that, this is all you ever see with the naked eye:
The Universe

Now, let's increase the scale - this is the size of our galaxy, compared to other known galaxies:
The Universe
Source
Now, let's get REALLY BIG - every light you see in this picture is a galaxy. Each galaxy contains hundreds of millions of stars and solar systems. Incredible!
The Universe
Source
This is galaxy UDF 423, you can see it in the bottom-right part of the picture above. UDF 423 is about 10 billion light years away from earth, meaning that the light needed 10 billion years to get from it to here. What you see is what this galaxy looked like 10 billion years ago!
The Universe

Now, just to up the ante - the image of the galaxies above was taken from this tiny, seemingly starless spot in the sky:
The Universe

You must have heard of "Black Holes", right? Well, in the center of galaxy NGC 1277 there is a supermassive black hole. If you need to know what "supermassive" means, look at its scale, compared to Earth's orbit around the Sun:
The Universe

So lets have a final recap - This is Earth, our home:

This is our solar system:

This is our solar neighborhood - these are just the solar systems in our part of the galaxy:

This is where our neighborhood resides in the Milky Way Galaxy:

This is the Milky way in its local galactic group:

This is our galactic group in what is known as the "Virgo Supercluster" - the local cluster of galaxies in our small part of the universe:
The Universe

This is where the Virgo Supercluster is located in the local supercluster neighborhood:

And this is the universe - as far as modern technology allows us to see:

So next time you're upset over something or the other, just remember that we're nothing but a tiny speck in a universe who's size we can't really comprehend...
