About 4.6 billion years ago, our Sun was born when a large cloud of gas in interstellar space collapsed under the force of gravity. The young Sun was surrounded by a rotating disk of gas, out of which planets, asteroids, and comets formed to complete our Solar System. Today, solar systems around newly formed stars are in the process of formation. With powerful new telescopes, especially the recently constructed Atacama Large Millimeter/submillimeter Array (ALMA) located in northern Chile, astronomers can capture pictures of the environment around newly formed stars to witness the formation of other planets. In this talk, I will present spectacular pictures from ALMA of disks around young stars that provide new insights on how planets form and on the origin of our Solar System.
