“The new ALMA images show the disk in unprecedented detail, revealing a series of concentric dusty bright rings and dark gaps, including intriguing features that suggest a planet with an Earth-like orbit is forming there.” -Sean Andrews
It takes a lot of work to make a solar system from the raw materials of an interstellar molecular cloud, but the Universe is up to the challenge. We had a theoretical picture that held for a long time, but thanks to the array of modern telescopes that humanity has constructed, we’ve finally been able to put that picture to the test.
Would protostars form from gravitational collapse? Would they wind up with protoplanetary disks around them? Would those disks develop asymmetries and, later, gaps where young planets formed? And then, would the central star ignite and burn off the rest of the materials, where only the planetary survivors would persist?
