À la recherche d'autres planètes habitables (FUN)

Offered by Communauté Université Grenoble Alpes,

La question de la vie sur d’autres planètes que la Terre est une question fascinante. Nous savons depuis les années 1990 que le système solaire n’est pas unique : il y a des planètes autour de nombreuses autres étoiles. Mais nous n’avons pas encore trouvé d’exo-planète véritablement similaire à la Terre. Au cours de ce MOOC, nous partirons à la recherche d’autres mondes habitables. Le premier chapitre vous plongera dans l’histoire des premières découvertes d’exo-planètes. Vous découvrirez les méthodes pour les détecter, et leur extraordinaire diversité.

Dans un deuxième chapitre, nous étudierons la manière dont les planètes se forment au sein de grands disques de gaz et de poussière autour des étoiles naissantes. Dans le troisième chapitre, nous retracerons les grandes étapes de l’apparition de la vie sur Terre, et vous découvrirez quels diagnostics les astronomes pensent utiliser pour identifier des formes de vie sur une autre planète.

Plan de cours

Semaines 1 & 2 : Détecter d'autres planètes
Semaines 3 & 4 : Former les planètes
Semaines 5 & 6 : Identifier la présence de la vie

Analyzing the Universe (Coursera)

Using publicly available data from NASA of actual satellite observations of astronomical x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae. We will analyze energy spectra and time series data to understand how these incredible objects work. We utilize an imaging tool called DS9 to explore the amazing diversity of astronomical observations that have made x-ray astronomy one of the most active and exciting fields of scientific investigation in the past 50 years.

There are lots of moons in our Solar System. The Earth is the only planet with just a single moon. Some are bigger than ours. Many are much smaller. Some moons have ongoing volcanic eruptions. Others have rivers of liquid methane. A small handful may even be home to primitive life. This online course will allow you to explore the rich diversity of moons in our Solar System.

In the past decade, astronomers have made incredible advances in the discovery of planets outside our solar system. Thirty years ago, we knew only of the planets in our own solar system. Now we know of thousands circling nearby stars.

Learn the concepts used in the design of space missions, manned or unmanned and operations, based on the professional experience of the lecturer. This course builds on university level physics and mechanics to introduce and illustrate orbital dynamics as is applied in the design of space missions. Simple tools will be provided to allow planning of missions on orbit around Earth or in the Solar System. You will learn from the experience of Claude Nicollier, one of the first ESA astronauts, specifically through his involvement in the Shuttle project and his role in the maintenance of the Hubble Space Telescope on two occasions.

Comment peser l'Univers ? Plus exactement, comment mesurer cette grandeur fondamentale qu'est la masse pour tout objet céleste ? Ce cours a pour objectif de vous initier aux différentes méthodes utilisées par les astrophysiciens pour mesurer la masse. Ces méthodes seront illustrées pour le Système solaire et jusqu'aux galaxies très lointaines. Ce MOOC sera aussi l'occasion d'aborder quelques recherches actuelles en astrophysique en lien avec cette problématique de mesure des masses dans l'Univers. En particulier, nous verrons comment les récentes observations d'ondes gravitationnelles permettent de peser les trous noirs.

Journey of the Universe weaves together the discoveries of the evolutionary sciences together with humanities such as history, philosophy, art, and religion. The course draws on the Emmy-award winning film, Journey of the Universe, and the book from Yale University Press. Journey explores cosmic evolution as a creative process based on connection, interdependence, and emergence. It examines a range of dynamic interactions in the unfolding of galaxies, Earth, life, and human communities. It investigates ways in which we understand evolutionary processes and the implications for humans and our ecological future.

Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.
