A colorful Rayleigh Background

The Space Shuttle Endeavour is featured in a very unique setting over the Earth’s colorful horizon in this Photo. And beholding this photograph instills a great deal of serendipity.

The light from the sun interacts with the different layers of atmosphere in this distinct fashion and this is attributed to a phenomenon known as Rayleigh Scattering.


In the lower thresholds of the atmosphere, the blue light and its variants are scattered away, leaving behind only red,orange and yellow shades to dazzle us, whereas in the upper atmosphere this scattering phenomenon of blue light is considerably lesser.

This produces the hypnotizing display of colors that you marvel. Amazing isn’t it?



Oh art nature,

How i wish everyone would truly appreciate

The beauty in you that is never to hate.

Mars: Red Planet, Blue sunset?

Mars has always been an interesting planet to us earthlings. The possibility of life, rovers leaving no stone unturned(literally), it’s demanding reddish appearance and now those breathtaking sunsets.Mesmerizing isn’t it ? But,

Why are martian sunsets blue?


Here on earth, sunsets are bright with Yellow, Orange and Red colors dazzling in the sky. During sunsets, the light from the sun has to travel a longer distance in our atmosphere to reach the earth.

Consequently, all the blue and violet light is scattered( thrown in various directions) by the particles in our atmosphere leaving behind only shades of yellow, orange and red, which is what you see. This phenomenon is known as Rayleigh scattering.


On mars, the reverse effect occurs. The martian dust is smaller and more abundant than on earth and it incidentally happens to be just the right size that it absorbs the blue light whilst scattering the red ones across the sky. This makes martian sunsets blue :).

Stay tuned, there is more space stuff coming your way.
