NEW: ARIEL Press Release (04/2019)ARIEL Data Challenge Series launched to build global community for exoplanet data solutions

ARIEL’s next Open Conference will be held on 14 – 16 January 2020

ARIEL, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was selected as the fourth medium-class mission in ESA’s Cosmic Vision programme. During its 4-year mission, ARIEL will study what exoplanets are made of, how they formed and how they evolve, by surveying a diverse sample of about 1000 extrasolar planets, simultaneously in visible and infrared wavelengths. It is the first mission dedicated to measuring the chemical composition and thermal structures of hundreds of transiting exoplanets, enabling planetary science far beyond the boundaries of the Solar System.

 ARIEL Press Release (04/2019) – ARIEL Data Challenge Series launched to build global community for exoplanet data solutions

ARIEL, a mission to make the first large-scale survey of exoplanet atmospheres, has launched a global competition series to find innovative solutions for the interpretation and analysis of exoplanet data. The first ARIEL Data Challenge invites professional and amateur data scientists around the world to use Machine Learning (ML) to remove noise from exoplanet observations caused by starspots and by instrumentation.

ARIEL Press Release (03/2018) –
ARIEL selected as ESA’s next medium-class science mission

ARIEL, a mission to answer fundamental questions about how planetary systems form and evolve, has been selected by the European Space Agency (ESA) as its next medium-class science mission, due for launch in 2028. During a 4-year mission, ARIEL will observe 1000 planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. ESA’s Science Programme Committee announced the selection of ARIEL from three candidate missions on 21st March 2018.

ARIEL Press Release (01/2015) –
Mission Announcement

An ambitious European mission is being planned to answer fundamental questions about how planetary systems form and evolve. ARIEL will investigate the atmospheres of several hundreds planets orbiting distant stars. It is one of three candidate missions selected last month by the European Space Agency (ESA) for its next medium class science mission, due for launch in 2026. The ARIEL mission concept has been developed by a consortium of more than 50 institutes from 12 countries, including UK, France, Italy, Germany, the Netherlands, Poland, Spain, Belgium, Austria, Denmark, Ireland, Portugal. The mission will be presented today at the Pathways 2015 conference in Bern, Switzerland, by ARIEL’s Principal Investigator, Prof Giovanna Tinetti of UCL.

“The essential nature of exoplanets is still something of a mystery to us: despite finding nearly 2000 exoplanets we haven’t yet found any discernible pattern linking the presence, size or orbital parameters of a planet to what its parent star is like,” said Tinetti. “If we are going to answer questions, such as how is the chemistry of a planet linked to the environment in which it forms, or is its birth and evolution driven by its host star, we need to study a statistically large sample of exoplanets. This is what ARIEL is designed to do.” Continue reading “Press Releases”
