ARIEL SPACE MISSION - ESA

The European Space Agency (ESA) has formally adopted Ariel.

What is Ariel?

Ariel (Atmospheric Remote-sensing Infrared Exoplanet Large survey) will be launched in 2029.
It will perform a large-scale survey of over a thousand exoplanets over a period of 4 years.
The explorer that will study the nature, formation and evolution of exoplanets.

Significance:

Ariel is the first mission of its kind dedicated to measuring the chemical composition and thermal structures of exoplanets.

How exoplanets are found?

Tracking the dimming of a star that happens when a planet passes in front of it.
NASA’s Kepler Space telescope uses this method to spot thousands of planets.
Gravitational lensing and the “wobbling method”, which is based on the idea that an orbiting planet will cause its parent star to orbit slightly off-centre.

Key Points:

Proxima Centauri b is the closest exoplanet to Earth and is 4 light-years away and inhabits the “habitable zone” of its star, which means that it could possibly have liquid water on its surface.
