A team of scientists has collected enough high-resolution Hubble Space Telescope images over a 14-year period to stitch together time-lapse movies of powerful jets ejected from three young stars.
The jets, a byproduct of gas accretion around newly forming stars, shoot off at supersonic speeds in opposite directions through space. These phenomena are providing clues about the final stages of a star's birth, offering a peek at how our Sun came into existence 4.5 billion years ago. Hubble's unprecedented sharpness allows astronomers to see changes in the jets over just a few years' time. Most... Read more
