First woman to command the International Space Station. Such a great picture.
Globular Cluster
It is a large group of old stars that are closely packed in a symmetrical, somewhat spherical form. Globular clusters, so called because of their roughly spherical appearance, are the largest and most massive star clusters.
The globular clusters in the Milky Way are all estimated to be at least 10 billion years old and therefore contain some of the oldest stars in the galaxy.

Not many people get to travel to outer space, but here, we can at least see what it looks like from amazing aerial perspectives. Landsat 5, a satellite that observed our planet for more than 29 years in space, will soon be ending it’s mission. Originally set to orbit Earth for three years, the satellite lived well beyond its intended means. But, a recently broken gyroscope has declared the end of the machine’s time in space.
It orbited Earth more than 150,000 times, capturing more than 2.5 million images of our world’s terrain. In honor of the mission’s end, here are a collection of Landsat 5’s best images of our planet. Landsat 7, which has been orbiting Earth since 1999, will remain overhead and Landsat 8 will be launched into space in February 2013.
Jupiter and its moons Europa, Ganymede, Callisto, and the Earth’s moon all caught in the same photo.
