A star is born :

HP Tau, 550 light-years from Earth, is the youngest star in a three-star system. (It’s the one at the top of the triangle.) HP Tau is in the process of turning into a star like our Sun, but it’s likely less than 10 million years old—for comparison, the Sun is around 4.6 billion years old.⁣

Scientists are using our orbiting @NASAHubble telescope to study HP Tau and learn more about protoplanetary disks, the disks of material around stars that form into planets over millions of years. HP Tau is also a variable star, which means that it gets brighter and dimmer over time. These variations could be due to the star’s turbulent childhood, with gas and dust around the star both blocking its light and feeding its growth. More predictable changes in brightness could be caused by giant sunspots rotating in and out of view.⁣
