PIX4598425: Apollo - Soyuz: Soyuz ship - Apollo - Soyuz: Soyuz above earth - The Soyuz ship seen from the window of Apollo. 17/07/1975. This scene was photographed with a handheld 70 mm camera from a rendezvous window of the American Apollo spacecraft in Earth orbit during the Apollo - Soyuz Test Project (ASTP) mission. It shows the Soviet Soyuz spacecraft contrasted against a black - sky background with the Earth's horizon below. ASTP was a cooperative space mission between the United States and the USSR. The goals of ASTP were to test the ability of American and Soviet spacecraft to rendezvous and dock in space and to open the doors to possible international rescue missions and future collaboration on manned spaceflights.

ITR4580486: Gardens and Chateau de Breteuil in Les Yvelines. Le Chateau did not take the name Breteuil until 1817, the name of the family that had owned it for more than a century. The castle is Louis XIII. Its roof and curved corner pavilions were inspired by Mansart in the 19th century. It was rebuilt between 1600 and 1629 by Thibault Desportes.

PIX4564490: Globular cluster M5 in Serpens - Globular cluster M5 in Serpens - This cluster of stars is located about 25,000 light years away from Earth. It is one of the most extensive (165 years - light) and one of the oldest known globular clusters. Globular clusters are generally peoples of very old stars, but here the Hubble space telescope has identified some young stars, blue stragglers. The globular cluster Messier 5, shown here in this NASA/ESA Hubble Space Telescope image, is one of the oldest belonging to the Milky Way. The majority of its stars formed more than 12 billion years ago, but there are some unexpected newcomers on the scene, adding some vitality to this aging population. Stars in globular clusters form in the same stellar nursery and grow old together. The most massive stars age quickly, exhausting their fuel supply in less than a million years, and end their lives in spectacular supernovae explosions. This process should have left the ancient cluster Messier 5 with only old, low - mass stars, which, as they have aged and cooled, have become red giants, while the oldest stars have evolved even further into blue horizontal branch stars. Yet astronomers have spotted many young, blue stars in this cluster, hiding among the much more luminous ancient stars. Astronomers think that these laggard youngsters, called blue stragglers, were created either by stellar collisions or by the transfer of mass between binary stars. Such events are easy to imagine in densely populated globular clusters, in which up to a few million stars are tightly packed together. Messier 5 lies at a distance of about 25 000 light - years in the constellation of Serpens (The Snake).

PIX4571594: The cloud of Oort - Illustration - The Oort cloud. Artwork - The Oort Cloud is a vast body envelope orbiting well beyond the orbit of the planets of the solar system. Comets would come from that cloud. The Oort Cloud is a huge spherical cloud surrounding our Solar System. Extending about 30 trillion kilometers (18 trillion miles) from the Sun, it was first proposed in 1950 by Dutch astronomer Jan Oort. The vast distance of the Oort cloud is considered to be the outer edge of the Solar System where the Sun's influence ends. It contains billions of icy bodies and seems to be the birth place of comets / Bridgeman Images
PIX4613977: Quasar - Illustration - Artist's view of the quasar ULAS J1120+0641, the furthest quasar discovered to date. This artist's impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked. This quasar is the most distant yet found and is seen as it was just 770 million years after the Big Bang. This object is by far the brightest object yet discovered in the early Universe / Bridgeman Images
