A new star may soon light up our sky, becoming visible even at naked eye. It is T Coronae Borealis, a recurrent nova located just under 3000 light-years away from us. In fact, it is the closest known object of this class to Earth. A nova is a system characterized by periodic explosions accompanied by sudden increases in brightness. These

Berkeley 59 is a young stellar clusters, which is experiencing a rapid asymmetric expansion Stars typically form in groups or stellar clusters containing from hundreds to thousands of members. Within these clusters, stars are not stationary but move along trajectories determined by the system’s overall gravity (that is, the gravitational potential of the cluster) and by their mutual interactions.

Rotation velocities measured for 330 B-type stars in eight stellar clusters of the Carina complex, thanks to the Gaia-ESO Survey. Stars rotate on their axes. Some, such as young stars, spin very rapidly, with rotation periods as short as one or two days. In other cases, like red giant stars, rotation is much slower, with periods lasting several months.
