A first mission of its kind, the Ariel space telescope will launch in 2029 to study the atmospheres of distant exoplanets outside of our solar system. Up to 12 Canadian astronomers, including ���ϲ����� University experts, will be at the front row of the mission, with privileged access to its data. <!-- x-tinymce/html -->(<a href="https://www.asc-csa.gc.ca/eng/news/articles/2023/2023-07-25-canada-to-contribute-to-esa-exoplanet-mission.asp">Canadian Space Agency</a>)</p> Tue, 25 Jul 2023 14:43:25 +0000 webfull 190667 at /channels /channels/channels/news/new-insights-seasons-planet-outside-our-solar-system-336430 <p><em>XO-3b, a hot Jupiter on an eccentric orbit.

Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away.
