  3. Tap an orbit line to select its body; host galaxies, companion stars and mass streams around black holes and pulsars plus route captions in the interstellar tour; cleaner reading layout for object pages and articlesSee it →

  4. Bylines, review and update dates on articles and object pages, an editorial policy section, today's picks on the home page, and this update logSee it →

  5. Interstellar 3D: the Milky Way sphere, nebula/galaxy photos and the galactic disk now render on the GPU — no more seams or shimmer, and the cinematic loop is no longer capped at 25 fpsSee it →
