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.

Jupiter’s Great Red Spot

This view of Jupiter was taken by Voyager 1. This image was taken through color filters and recombined to produce the color image. This photo was assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory. JPL manages and controls the Voyager project for NASA’s Office of Space Science.

Dextre and Arabian Nights: ISS takes bot for dreamy flight over magnificent Middle East (follow link for VIDEO)

New International Space Station (ISS) footage reveals the staggering and fragile beauty of the Middle East at night, when all the violence of the region seems to have stilled and only glimmering lights indicate the pulse of life. The time-lapse footage, showing the ISS hovering over the Middle East at night time, was released on Friday.
The video also features Dextre, the spacecraft’s trusty repair-bot that completes such tasks as changing batteries and replacing cameras outside the ISS. The robot, also known as the Special Purpose Dexterous Manipulator (SPDM), reduces the need for routine spacewalks. There are currently six people aboard the International Space Station.One of the astronauts, Scott Kelly, never misses a chance to reveal Earth’s astounding beauty which just can’t be appreciated from the ground. He has posted a series of photos in his Twitter blog displaying the amazing textures of mountains and seas as seen from space.

Stellar Sparklers That Last

While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time. NGC 1333 is a star cluster populated with many young stars that are less than 2 million years old – a blink of an eye in astronomical terms for stars like these expected to burn for billions of years.
