The night sky...

Posted by Liron on Thursday, January 29, 2015
In school right now, my Science teacher. Mr. Procyk, recipient of the Prime Minister's Award for Teaching Excellence, has been teaching us about astronomy. What I have learned is really amazing, and it inspired me to go back and process a couple photos I took of the night sky in Costa Rica in July 2013. These photos were taken in the Cerro De La Muerte region of Costa Rica (Mountain of Death), away from the light polluted sky of the city.

Both these photos were taken with a Canon EOS Rebel T1i, Tokina 16.5-135mm F3.5-56 AT-X DX lens at 30 seconds, ISO 800, and f3.5. The first was at 19mm and second was at 17mm.

Costa Rica night sky

I have been taught a whole new meaning for big... the milky way where we are is just one of countless galaxies in the universe, all constantly being pushed farther away from each other, making the universe larger and larger. From what we can see most of these stars all have their own set of planets orbiting them, meaning there could be trillions of earth-like, livable planets that are currently well beyond the reach of where we can go. The nearest star to us, Alpha Centauri, is 41,314,127,522,900 KM away, and that is the closest star (according to my calculations of 1 light year being 9.4605284 × 10 to the 12 kilometers multiplied by Alpha Centauri's distance of 4.367 light years from earth). If that is the closest star, the distance to the stars in these pictures is unimaginable. We are looking at worlds so far away that the light that we see left them lifetimes ago.

It is very hard to grasp, so for now I am just going to appreciate how amazing the night sky appears, especially away from the city like in these pictures!

Thanks for looking! I will get back to bird pictures soon...
