Space Interferometry Mission

The Space Interferometry Mission also known as SIM Lite and formerly known as SIM PlanetQuest is equipped with a 6-meter Michelson stellar interferometer, operating in the visible waveband, and will be launched into an Earth-trailing solar orbit where it will operate for a mission lifetime of five years....

Darwin Mission

The European Darwin Mission will be a flotilla of four or five free-flying spacecraft that will search for Earth-like planets around other stars and analyse their atmospheres for the chemical signature of life in the mid of the next century....

Terrestrial Planet Finder (TPF)

The Terrestrial Planet Finder is a mission which primary target is to search after Earth-like planets and currently under study by NASA. At the moment are two complementary concepts for this mission. The visible-light Coronograph and a formation-flying infrared Interferometer....

  • Kepler Space Telescope

    image
    The Kepler Space Telescope from NASA is designed to discover Earth-like planets orbiting other stars. The telescope is named after the German astronomer Johannes Kepler (1571-1630), which is best known for the Kepler's laws of planetary motion.

  • COROT Space Telescope

    image
    COROT stands for Convection Rotation and planetary Transits and is a big step forward for the ESA for the search after 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.

  • Black Holes

    image
    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

    image
    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

    image
    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

    image
    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.
