When the changes in the light are detected, they indicate the chemical composition of the planet's atmosphere and whether it is likely to support life or not. When an orbiting planet moves in front of its star relative to the observer, the spectrum of light from the star changes as it passes through the planet's atmosphere.

Spectroscopy of transiting exoplanets is one of the main techniques in exoplanet astronomy. Now JWST's spectroscopy instrumentation offers an unprecedented opportunity to study exoplanets for the chemical signatures of life in their atmosphere. He and his colleagues developed a data tool to exploit the wealth of existing spectroscopic data from previous missions to study exoplanets.įrom a standing start, exoplanet astronomy has discovered thousands of exoplanets in the past 20 years. Lagage is the principal investigator of the H2020-funded Exoplanet Atmosphere New Emission Transmission Spectra Analysis, or ExoplANETS A project. 'An exoplanet is a planet orbiting a star other than the sun,' Lagage said. These include the study of the early universe shortly after the Big Bang, galaxies and star formation, black holes, our own solar system and the search for the building blocks of life in the universe. Like many astronomers in Europe, Pierre-Olivier Lagage, an astrophysicist at the Paris-based French Alternative Energies and Atomic Energy Commission (CEA), has been preparing for JWST for years.Ī joint project with NASA, the Canadian Space Agency (CSA) and the European Space Agency (ESA), JWST started beaming back its first images of the cosmos in July 2022 after arriving at its vantage point 1.5 million kilometers from the Earth and unfurling its distinctive giant sunshield.Ī worthy successor to the iconic Hubble Space Telescope, the €10 billion JWST has big scientific goals.

Since its Decemlaunch aboard an Ariane 5 rocket from French Guiana and following 30 years in the making, the James Webb Space Telescope (JWST) is the Christmas Day gift to astronomers that keeps on giving.
