  What's new in the version 0.427

  Updated on Nov 1, 2026

  • Gas giants: impacts now stir up the clouds and make the planet wobble
  • Impacts on stars leave a dark mark
  • Fast-spinning bodies flatten realistically, giants like the real ones
  • 30 extra stars from the constellations (Orion, Big Dipper, Cassiopeia…); each card names its constellation

  What's new in the version 0.426

  Updated on Oct 31, 2026

  • All-new stars: living surfaces with granulation, spots, flames and prominences; each star type has its own look
  • Eta Carinae: colliding stellar winds, accretion and jets
  • New: the Butterfly Nebula (NGC 6302) in 3D
  • Black holes: more realistic lensing and accretion disk, new disk settings
  • Find: type to search
  • Faster start, lower memory use

  Updated on Oct 25, 2026

  New in 0.422:
  • Close binary stars: stars stretch into teardrops and pour gas onto their partners.
  • Magnetars: five real magnetars with visible magnetic fields. Turn any neutron star into a pulsar or magnetar.
  • New info card with composition and life probability for every body.
  • Solar wind flowing around planetary magnetic fields.
  • New systems in nearby galaxies, including SN 1987A.
  • Nix, Hydra, new companion stars and better brown dwarfs.

  What's new in the version 0.416

  Updated on Oct 12, 2026

  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.

  What's new:
  • Nebulae! Explore 3D models of the Eagle Nebula with the Pillars of Creation, the Crab Pulsar and its nebula, the Helix Nebula, the Vela Pulsar with its supernova remnant, and the Homunculus Nebula around Eta Carinae. They are based on scientific data, with the missing parts filled in by artistic license :-)
