Learn about the science behind the current exploration of the solar system in this free class. Use principles from physics, chemistry, biology, and geology to understand the latest from Mars, comprehend the outer solar system, ponder planets outside our…
This course is designed for anyone who is interested in learning more about modern astronomy. We will help you get up to date on the most recent astronomical discoveries while also providing support at an introductory level for those who have no backgrou…
Learn about the origin and evolution of life and the search for life beyond the Earth.
We have learned a lot recently about how the Universe evolved in 13.7 billion years since the Big Bang. More than 80% of matter in the Universe is mysterious Dark Matter, which made stars and galaxies to form. The newly discovered Higgs-boson became froz…
Learn about the Earth, life, and how we can search for life elsewhere in the universe.
Learn about the atmospheric chemistry of planets and celestial bodies and explore the possibility of finding life beyond Earth.
To look for evidence of life on other planets, we have to adapt what we know about chemistry on Earth to aid our search. Astronomer Dimitar Sasselov explains how we can use what we already know to search for alien life in this Master Class.
What is a black hole? Do they really exist? How do they form? How are they related
to stars? What would happen if you fell into one? How do you see a black hole if they
emit no light? What’s the difference between a black hole and a really dark star?
Theoretical physicist Andrei Linde was responsible for proposing the ideas of an inflationary multiverse and eternal inflation. In this Master Class, Linde discusses the evolution of these ideas over the past decades and what the future of cosmology hold…
Breakthrough Prize winner Andrew Strominger and string theorist Cumrun Vafa rediscovered the elusive quantity of black hole entropy in a groundbreaking calculation. Join Professor Strominger for an overview of how string theory has allowed us to understa…
Explore the history of navigation, from stars to satellites.
Course covers the basic principles of Einstein's general theory of relativity, differential geometry, experimental tests of general relativity, black holes, and cosmology.
The Origins course tracks the origin of all things – from the Big Bang to the origin of the Solar System and the Earth. The course follows the evolution of life on our planet through deep geological time to present life forms.
Archaeoastronomy is the “science of stars and stones”. It is an interdisciplinary science in between architecture, archaeology, and astronomy. It studies the relationships between the ancient monuments and the sky, in order to gain a better understandin…
The first part of the course deals with the classical cosmology, and later part with modern particle physics and its recent impact on cosmology.
