Beautiful Space Photos

Here are some beautiful space photos and video that have been posted on the Internet in recent weeks.  Enjoy!

This beautiful photo of the Milky Way was taken from Concordia Research Station, a remote Antarctic facility run by French and Italian scientists. The scientists at this facility are cut off from civilization during the winter months – no chance of resupply or rescue … much like future space explorers!

This image of the Pinwheel Galaxy, or also known as M101, combines data in the infrared, visible, ultraviolet and X-rays from four of NASA’s space-based telescopes. This combination of telescope views into one image shows that both young and old stars are evenly distributed along M101’s tightly-wound spiral arms. Such composite images allow astronomers to see how features in one part of the spectrum match up with those seen in other parts. It is like seeing with a regular camera, an ultraviolet camera, night-vision goggles and X-ray vision, all at the same time.

The Pinwheel Galaxy is in the constellation of Ursa Major (which includes the Big Dipper). It is about 70% larger than our own Milky Way Galaxy, with a diameter of about 170,000 light years, and sits at a distance of 21 million light years from Earth. This means that the light we’re seeing in this image left the Pinwheel Galaxy about 21 million years ago – many millions of years before humans ever walked the Earth.

The hottest and most energetic areas in this composite image are shown in purple, where the Chandra X-ray Observatory observed the X-ray emission from exploded stars, million-degree gas, and material colliding around black holes.

The red colors in the image show infrared light, as seen by the Spitzer Space Telescope. These areas show the heat emitted by dusty lanes in the galaxy, where stars are forming.

The yellow component is visible light, observed by the Hubble Space Telescope. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes seen in the infrared.

The blue areas are ultraviolet light, given out by hot, young stars that formed about 1 million years ago, captured by the Galaxy Evolution Explorer (GALEX).

England at Night

Billions of people are seeing London through many different filters and lenses during the 2012 Olympic Games and Paralympic Games. None of those views looks quite like this one from NASA’s Suomi National Polar-orbiting Partnership satellite.  The image above shows London and the southern half of Great Britain as it appeared on the night of March 27, 2012.

Taikonaut Liu Yang

China’s first female astronaut (called “Taikonaut” in China), Liu Yang, emerges from the re-entry capsule of Shenzhou-9 spacecraft, which landed in China’s Inner Mongolia Autonomous Region Friday, June 29, 2012. Liu and two other crew members returned safely to Earth after a 13-day mission to an orbiting prototype space station, the Tiangong-1.

Humanity’s robot orbiting Saturn has recorded yet another amazing view. That robot, of course, is the spacecraft Cassini, while the new amazing view includes a bright moon, thin rings, oddly broken clouds, and warped shadows. Titan, Saturn’s largest moon, appears above as a featureless tan as it is continually shrouded in thick clouds. The rings of Saturn are seen as a thin line because they are so flat and imaged nearly edge on. Details of Saturn’s rings are therefore best visible in the dark ring shadows seen across the giant planet’s cloud tops. Since the ring particles orbit in the same plane as Titan, they appear to skewer the foreground moon. In the upper hemisphere of Saturn, the clouds show many details, including dips in long bright bands indicating disturbances in a high altitude jet stream. Recent precise measurements of how much Titan flexes as it orbits Saturn hint that vast oceans of water might exist deep underground.

Here is a new video of time-lapse imagery of Earth taken from space courtesy of the Image Science & Analysis Laboratory, NASA Johnson Space Center.  This video was set to music by Tomislav Safundžić.
