Is the Milky Way still forming stars?
Within the Milky Way, there are only a few instances of young, blue, newly formed stars. Up until now, practically all of them originated from recent star-formation events in the disk of our galaxy, driven by the density waves of our spiral arms and the collapse of cool gas.
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
