European Space Agency to Investigate Living Planets


Exploring planets, habitable planets has always been one of the greatest goals for astronomers and humans. Many studies are underway for this, and one of them has started to work with CHEOPS.

A new space telescope has been sent to Earth's orbit today. The task of the telescope legislative convenient Examine distant planets. The CHaracterising ExOPlanets Satellite (CHEOPS) will be the first mission to focus on the small exoplanets in the orbits of the already discovered bright stars. These include small gas giants, super worlds and small rock planets like Earth and Mars.

CHEOPS is supported by the European Space Agency (ESA) and the Swiss Space Office. The same design as the telescopes used in the Hubble and Spitzer space telescopes on the satellite Ritchey-Chrétien telescope. CHEOPS was launched Wednesday after a short delay from French Guiana.

Importance of CHEOPS in planet data

Tasks such as Kepler and TESS had identified many potential exoplanets, but information was seldom acquired except for its location, estimated mass and orbital characteristics. Scientists can predict what kind of planet these features are, so some planets “Potentially Earth-like” in the form of qualifications. CHEOPS will provide new data to help characterize these planets.

In CHEOPS, enough to collect data as exoplanets pass in front of their stars precision photometers It features. Many known exoplanets pass through their stars in our perspective because it is the most efficient way to detect transitions, and now Kepler has discovered thousands of potential exoplanets.

CHEOPS can measure radii of exoplanets, and the mass of many of the exoplanets is already known. When these two information are combined, the density can be calculated. These data will tell scientists whether the observed super world is solid like Earth or a small gas giant like Neptune.

Team, CHEOPS three and a half years designed to remain in office. During this mission, the satellite will observe small, potential earth-like planets, but the target list will constantly expand. Exoplanets explored by CHEOPS expected to be launched in 2021 James Webb Space TelescopeWill become the main goals of the future.
