New: stellar evolution! Let stars grow into red giants that swallow their inner planets, then shed their envelope to leave a white dwarf and a planetary nebula.
Supernovae now leave a white dwarf, a pulsar or a black hole, depending on the star's mass.
Hear pulsars tick at their real rotation rate.
Explore 5 real nebulae in 3D: Crab Pulsar, Helix, Vela Pulsar, the Eagle with the Pillars of Creation, and the Homunculus.
Plus clearer buttons and many fixes.
