cosmos: a spacetime odyssey astronomy stars
Every star is a sun as big, as bright, as our own. Just imagine, how far away from us you’d have to move the sun to make it appear as small and faint as a star. The light from the stars travels very fast. Faster than anything. But not infinitely fast. It takes time for their light to reach us. For the nearest ones, it takes years. For others, centuries. Some stars are so far away it takes eons for their light to get to Earth.
By the time the light from some stars gets here they are already dead. For those stars, we see only their ghosts. We see their light, but their bodies perished long, long ago.

Miniature Galaxies Created Through Tilt-Shift Technique
With the use of a relatively simple photography technique, Italian artist
Haari Tesla has reduced the cosmos to a microscopic level. Her series, Illuminated Code From Space, is experimentation in tilt-shift manipulation. By digitally adjusting the depth of field, contrast, and adding a gradient, Tesla has managed to transform photos of nebulae, galaxies, and supernovae into microorganisms. It’s incredible to look at these images and realize that they are actually photos of the largest place we know, rather than of something so small it can’t be seen with the naked eye.
The initial idea for the series came from the Greek Neo-Platonic schema of macrocosm and microcosm. Essentially, this is the recognition that the same traits appear in entities of many different sizes. Plato wrote about how we see these patterns reproduced in all levels, from the largest scale (macrocosm, or the universe) all the way down to a microscopic level (also know as microcosm),
They look like such delicate things that you keep in a high shelf.
I will always reblog this.
Understand your significance. Allow Carl Sagan to lull you into an intellectual dream state in an intellectual stellar symphony — “Star Stuff: Carl Sagan on stellar evolution" from the Carl Sagan Tribute Series.

Artist Leonid Afremov uses oil paint to bring warmth and light to the canvas as he paints what he sees as beautiful. "Each of my artworks reflects my feelings, sensitivity, passion, and the music from my soul. True art is alive and inspired by humanity."
