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. • Many fixes and improvements.

What's new: • Dozens of new nearby systems, with info cards (tap "I" next to the name) • New comets: 67P, Swift-Tuttle & NEOWISE, with ion and dust tails • Hear pulsars tick at their real rhythm when you come close • Turn sunlike stars into red giants, then into white dwarfs • Give any star a Kuiper belt, Oort cloud or custom nebula • Redesigned orbit lines • Smoother on phones, especially older devices • Bigger, walkable impact craters with crater walls • Supernova lag fix • Many fixes

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.

• 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 :-) • Find them in the new Nebulae list, or add any nebula to a star. • Two new models: the International Space Station and the Space Shuttle.

New in this update: • Fresh look: redesigned menus, panels and HUD • New texture picker with live preview • Premium: no ads, 20 save slots with screenshots, and import your own 3D models (GLB, OBJ, STL) • New: the Starman Roadster and the Dagger space station • Walk on small asteroids • Impact craters now have raised rims, and the cloud blast works again • Sharper shadows and eclipses • Many fixes and performance improvements
