A small perspective

Here is a small perspective on you, me, us, and our planet, earth that we live on. We live on possibly the only planet that seems to have intelligent (pretentious) life forms. And instead of trying to protect it, we are looking to find other life forms. Why? Well possibly to export our destructive powers?

Earth (12600 km), with its satellite Moon (3500 km)

Venus is about the same size as Earth

Suddenly dwarfed in comparison with Neptune and Uranus

Jupiter's diameter is 143,000 km

All pale in comparison with our Sun - 1,392,000 kilometers !

Sun is not the largest star in our galaxy, Sirius something bigger at ~2,500,000km

Pollux is about 8.3 times of Sun

Arcturus is about 31 times the size of Sun.

Aldebaran is 51 times. Sun is a mere dot in this pic.

VV Cephei is about 2400 light years away from Earth

Canis Majoris is ~2000 times our Sun

At this point we, our earth, cannot even be represented. All of this within our Milky Way or nearby galaxy. The Milky Way, Akash Ganga galaxy itself is about 1 million light-years in diameter. The solar system is not at the center of the galaxy, as is normally represented.

So, if it took God (as supposed some where), 6 days to create our planet, and one day to rest, i strangely feel (s)he is still working somewhere.

At end of this, i wonder if this is the right time to bring up my problem with including and positioning  large images in my blog.

I tried to locate the original pictures, in an effort to find out the authenticity too. Unfortunately no luck there, and apparently several people also tried the same without luck. So bless the person or persons who created this. I assembled these from two or more sites. It took me over a week or so do this, i have almost lost the sites where i picked up which pictures. But if you do a simple search for 'earth size perspective' you will hit a dozen, refine your searches and see more refined(?) versions.

3rd Largest Rocket Engine

Is this important ? Of the many agencies that the Indian government has created, ISRO has been continuously achieving successes, and this testing will be one more step in its 'giant leap for the desi humankind'.
From what little i know of what the ISRO does, it not only builds and launches rockets and sattelites, it actually has been taking a lot of initiatives to spread the use and application of space technology. I know first hand of how ISRO team interacts with users on the tele-medicine front.

I think it is important, in this day and age. Kudos to them, and hope they achieve more success. I'm personally looking forward to more launches from ISRO.

Chandrayaan-I finds traces of water on moon

So we are able to trace water on the moon. But down here on our land and planet, we are still searching.
