Flocculent spiral galaxy NGC 2841, shown in photographs, is known for its abundance of young blue stars. But until recently, astronomers have not been technically possible to study these stars, so their example to better understand the mysterious process of star formation. Upgrading the Hubble camera, held in 2009, lets look at the galaxy NGC 2841 with a new angle.
