Our Amazing Neighbourhood









Is it not beautiful? :) This is what you will see on the sky if you lie down on the lawn of your home on a dark silent night, on grass, with sweet earthly scent around, slight dew and once in a while gentle breeze.

A new panoramic image of the full night sky — with the Milky Way as its centerpiece — has been made by piecing together 3,000 individual photographs. The panorama's creator, Axel Mellinger of Central Michigan University, spent 22 months and traveled over 26,000 miles to take digital photographs at dark sky locations in South Africa, Texas and Michigan. "This panorama image shows stars 1,000 times fainter than the human eye can see, as well as hundreds of galaxies, star clusters and nebulae," Mellinger said. To combine these images, a simple cutting and pasting job would not suffice. Each photograph is a two-dimensional projection of the celestial sphere. As such, each one contains distortions, in much the same way that flat maps of the round Earth are distorted. In order for the images to fit together seamlessly, those distortions had to be accounted for. To do that, Mellinger used a mathematical model — and hundreds of hours in front of a computer.

Mega-star explosion most distant object ever seen

This is the most distant star-burst captured. and it is 13.1 billion light years far. You cant even imagine how far that is.

GRB 090423 is the small, very red source in the centre of this image. The red colour is indicative of its great distance - about 13.1 billion light years - since all the optical light has been absorbed by intergalactic hydrogen gas, leaving only infrared light. All the other galaxies and stars in the image are much closer to us and just happen lie in the same part of the sky.


Astronomy humbles you.

"In Afghanistan and North Western Pakistan, burqa is very common - not becasue of religion but due to custom. Had it been religion then every muslim women on earth would have worn burqa."

Wrong.

It is because of religion that burqa is being worn here, religion introduced it. When there was no Islam in Indian subcontinent there was no burqa. Never forget the history of things even if they have now become a custom.

I am talking of 'burqa' - that usually blue coloured garment worn by women. Pardah is recommended by religions, Islam too - Not burqa.
