Space is almost all empty. That turns out to be the beautiful part. Every picture of the solar system you've ever seen tells you small white lies. The planets are swollen so you can see them. The orbits are squashed flat and drawn as tidy circles. Everything is crowded together so it fits on the page. Cosmic Specks is the same solar system with the lies switched off, one at a time, so you can build an intuition for what was actually removed. IT OPENS WITH THE ARGUMENT. A ninety-second tour names the five lies and switches each one off, live: the sizes, the flatness, the circles, the stillness, the diagram eclipses. IT ISN'T FLAT. Turn on inclinations and the orbits fan out into the tilted planes they really occupy — Pluto's 17°, Mercury's 7°, the quiet disagreement the flat diagram hides. EVERYTHING SPINS. Each body turns on its own axis, at its own rate, at its own lean: Venus backwards, Uranus on its side, the Moon locked forever facing home. HALLEY'S COMET TAKES AN EPIC RUN. Seventy-six years, out past Neptune and back, on an orbit so long and lopsided it barely belongs on the same diagram. SWIM THROUGH TIME. Watch conjunctions close, planets loop backwards through retrograde, Saturn's rings turn edge-on and all but vanish, Venus cross the face of the Sun. JUMP TO A PRECISE ECLIPSE and see how tight the Moon's shadow really is — a couple of hundred kilometres of darkness, brushing over the Earth for a few minutes, landing on the real map where it really lands. On 2 August 2027 it crosses southern Spain and Egypt; jump there and watch. And when you want the honest picture of size: one tap drops everything to true scale, where the planets become the specks they are, and the emptiness is the whole photograph. HONEST BY CONSTRUCTION. Every solar-system app draws a picture; this one also shows you the picture's error. Bodies are enlarged so you can see them at all — and the exact factors are printed on screen the entire time you're looking (Sun ×24, bodies ≤×750). Positions are computed on your device from orbital elements, so the app also tells you when it stops being trustworthy: good near today, approximate centuries out, illustrative in the deep millennia. Even the maps admit their gaps: Miranda is half blank because humanity has only ever seen half of it. WHAT IT DOESN'T DO. No account. No ads. No subscription. No analytics — App Privacy is "Data Not Collected". Nothing leaves your phone. Free, with one optional purchase that opens 10,000 years in each direction.

Most "space" apps show you renders, simulations, or a wall of data. EarthView does something different: it shows you the real Solar System — and gives it a voice. It opens on Earth, live. The natural-color imagery comes straight from NASA's EPIC camera aboard the DSCOVR satellite, a million miles away at the Sun–Earth L1 point, looking back at the fully lit face of our planet. The frames auto-play, so you watch Earth actually rotate through the day. No telescope. No CGI. The real planet, as it looked today. Then start the journey. A calm AI guide flies you outward through the Solar System — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune — and the Sun, narrating each world as you arrive, in genuine NASA mission imagery. Pick a theme and it plans the route for you. Curious about what you're seeing? Ask the guide — it answers about the exact world on your screen. - A narrated, AI-guided tour — every world spoken as you arrive - Live, auto-rotating Earth from NASA DSCOVR·EPIC, refreshed daily - Live Sun and Earth time-lapses from real feeds (SDO, GOES) — not loops - Real Mars rover imagery and curated NASA stills for every planet - Ask the guide anything, grounded in what you're looking at - No account, no ads, no in-app purchases — opens straight on Earth EarthView isn't a data tool or a research app. It's a small, beautiful window on the real Solar System, with a guide in your ear — the overview effect, in your pocket. (Note: NASA's EPIC imagery publishes with a short delay, so "live" means the latest real captured set, refreshed daily — not a real-time video feed.)
