Be sure to click into the larger view of this photo. It’s the extensive cloud of stars at the center of our Milky Way galaxy, over Arecibo Observatory in Puerto Rico. We see this Milky Way star cloud because, in this direction, we’re looking toward the galaxy’s center. Ferdinand Arroyo, from Sociedad de AstronomÃa del Caribe (Astronomical Society of the Caribbean) took this beautiful photo using a Nikon D90 with a Sigma 10mm lens. 30 secs exposure at ISO 1600, F/4.
Thank you, Ferdinand and Sociedad de AstronomÃa del Caribe!
By the way, in case you are wondering, here’s what the observatory looks like in daylight.
