Herschel Space Telescope
Herschel is the largest space telescope ever launched. Its 3.5 m-diameter mirror will give astronomers their best view yet of the Universe at far-infrared and sub-millimetre wavelengths.
Planck Space Telescope
Planck is Europe’s first mission to study the relic radiation from the Big Bang....Interview with Bernard Foing about the European SMART-1 Mission

COROT Space Telescope
COROT stands for Convection Rotation and planetary Transits and is a big step forward for the ESA for the search for extrasolar planets. It is the first mission for the search after rocky planets around nearby stars. Furthermore it is the first European Mission for asteroseismology at other stars.

Chandra X-Ray Observatory
The Chandra X-ray Observatory, formerly known as the Advanced X-ray Astronomical Facility (AXAF), launched by Space Shuttle Columbia on July 23, 1999 and belongs to NASA's Great Observatory program. Also to the program belong the Hubble Space Telescope, the Compton Gamma Ray Observatory and the Spitzer Space Telecope.

Dawn Mission
NASA's Dawn Mission will examine the asteroids Ceres and Vesta. In fact in March 2006 was the Mission canceled but short time later the NASA Management decided to reinstate the Dawn mission, because many scientist all over the world supported the mission.
-
Deep Impact
NASA's Deep Impact mission is the astronomical highlight of the year, because for the first time a probe will hit a comet to reveal the secrets of its interior. The Deep Impact probe releases 24 h befor the arrival at the target Tempel 1 the small "impactor" (370 kg) which predominantly consists of copper.

Hubble Space Telescope
The Hubble Space Telescope was launched 1990 with the Space Shuttle Discovery and is one of the most important and popular telescopes in the history of astronomy.

Black Holes
Black holes are objects so dense that not even light can escape their gravity and since nothing can travel faster than light, nothing can escape from inside a black hole. The expression black hole was coined by John Wheeler.
-
Brown Dwarfs
Brown dwarfs are the link between stars and planets and are not massive enough like stars on the main sequence and sometimes called as failed stars. As a result of their mass-poor they don't start the hydrogen fusion. But brown dwarfs heavier than 13 Jupiter masses do fuse deuterium.
-
Mars
The planet Mars is the last terrestrial planet and the fourth planet of our solar system. He is the most likely target for a manned space mission. Already the first ancient civilizations were fascinated by him and honoured Mars as a god (for Romans/Greeks were he the god of war).
-
Venus
Venus is the second planet from the sun and belongs to the terrestrial planets, sometime Venus is called Earth's sister planet, because both are very similar in size, mass and composition. Venus is named after the Roman goddess of love.

The results of the Huygens Mission
After a journey of 7 years on board the American Cassini spacecraft the little European space probe Huygens was released on 25 December 2004 and reached the upper layer of Titan's atmosphere on 14 January 2005. After a parachute descent of 2 hours and 28 minutes the probe landed on the mysterious Saturn moon Titan. Now the first results were released by the European Space Agency (ESA).
