My favorite is the one from Coursera – Astrobiology and the Origins of Life, from the University of Edinburgh. With editions every year, it gives you the chance to enroll whenever you want and offers extensive knowledge on the topic. Besides, it is taught by Prof. Dr. Charles Cockell, which makes it super easy to follow and keeps you motivated throughout the course.
