Space Pictures This Week: Shuttle Swap, Hubble's Jewels

The remains of a Sun-like star wings butterfly painting through the cosmos in a recently published infrared image of Messier 27, also known as the Dumbbell Nebula, taken by the Spitzer Space Telescope.

The object is what is known as a planetary nebula, so called because astronomers had thought that the first interstellar clouds of light as the Jovian planets. In fact, what is clear is when the stars die and medium shed their outer layers of gas.

M27 was discovered by Charles Messier in 1764, which included the now famous list of vague objects. While Messier did not realize at the time, handlebars was the first planetary nebula, he said.

Endeavour is moved to the orbiter processing facility to make way for Kennedy to the discovery, he was transferred to the CPO for the technicians to prepare the profession to retire from the museum display.

European Night Lights

A picture recently published by NOAA satellite shows the changes in night lights in Europe between 1992 and 2009. Areas where yellow lights indicate that they have increased, where the lights show purple have decreased, and the white areas show no change.

The image reveals dramatic changes in Eastern Europe, probably related to the dissolution of the Soviet Union in 1992, when more people moved west and the urbanization of former Soviet states has declined.

Crete is the largest Greek island and the largest population that extends 161 miles (260 kilometers) from east to west. From 2700 to 1420 BC The island was the cultural center of the Minoan civilization, and is said to have been the home of the legendary Minotaur.

Bright, dense knots of gas light like jewels in a table published recently by the Hubble telescope the nebula collar, a planetary nebula about 15,000 light-years. Discovered in 2005, the dress is actually a cosmic cloud of gas and dust created by the death of a sun-like star

Around 10,000 years ago a dying star swells into a red giant, enveloping a nearby companion star. This is because the core of the dead star and the companion star is seen along the top as a central point to spin around each other so rapidly that they now carry an orbit in less than a day.

Because of centrifugal force, most of the gas escaped from the star along the equator of the star to produce a ring full of unusual.

The land around the bay is dotted with lakes icing call, which are created by water released as the thawing of permafrost.

Thawing permafrost and thermokarst lakes both release carbon dioxide and methane gases in the atmosphere, scientists monitor these landscapes to unravel the implications of climate change in the future.

A small crater on the crater rim Oskison more mercury is cast in high relief on a satellite image taken by NASA's MESSENGER and released August 15 Sunlight casts shadows that help show deep corner terraced walls of the crater and smooth floors.

The image is part of a series being compiled by email to create a base map with high resolution. The map of time will cover 90 percent of the planet's surface, helping scientists better understand the topography of the battered world.




Dismal Fire

Cascades of smoke south of Outer Banks in North Carolina in an image of southern West Virginia is lateral wildfire, as a NASA satellite on August 10 Lightning started the fire on August 4 in the dry grass and brush of pines of the Great Dismal Swamp National Wildlife Refuge.

Since August 9 the fire had burned 3,200 acres (1295 hectares), and fire managers say it will take at least six inches (15 cm) of rain in a short period to settle naturally.
