Hypnotic Photographs of the Milky Way Over Yellowstone National Park

After a storm passed through Yellowstone National Park, astrophotographer David Lane captured the stunning beauty of the Milky Way covered sky above the Abyss Pool region. Although the photographs were taken at night, the illuminating beauty from the Milky Way gave the landscape sufficient light and a magical element to deliver this stunning sight. This natural phenomenon is defined as an airglow impedes the sky from becoming completely dark. To assure that the images match the park’s vision during the day time, Lane spent four extra months on color correcting his collection. 

From a tweet by Nasa. This is an artists depiction of a black hole. Ive always found black holes amazing; theyre like parts of the universe where the universes game engine bugs out and makes weird errors.

The black half circle in the center is the black holes event horizon, where gravity becomes so strong that the escape velocity exceeds the speed of light. Its termed the event horizon because any event that occurs within it cannot be seen by nor measured by nor can it affect the outside universe.

Surround it is the accretion disk, matter spiralling into the black hole that begins to heat up due to tidal forces and friction. Finally, the expanding beam shooting out of the top is the relativistic jet: particles flung out before reaching the event horizon at absurdly high speeds.

The agency has created a virtual tour, allowing users to navigate around the orbiting outpost as if it were Google’s Street View.
