Features

Everything it does

Each feature in plain words. The newest are on What's new, which links here.

One camera, from the galaxy to EarthStart at the edge of the Milky Way and fly to the Sun, a planet or your own country. There is no cut and no loading screen between one scale and the next.
32,639 real starsEvery star within 300 light-years and every star of magnitude 7 or brighter, at its measured place, in its own colour, as bright as it is from where the camera stands. Named stars show their names.
Nebulae and black holes28 nebulae built from their photographs, and black holes such as Cygnus X-1, each in its real direction.
ToursA nine-stop tour of the solar system and a 76-stop tour of the galaxy, advancing by themselves or by hand.
Measured, worked out or drawnEvery card says which of the three it is. The disc of the galaxy is an artist's impression, and says so.

Every planet where it is nowThe planets and six moons are placed from their orbits for the instant on the clock. Run time forward or back, or press Now.
The Solar System's own cardPulled back over the whole system, the card is the system's: its star, planets and moons, how far across Neptune's orbit is and how long light takes to cross it, its age, and its tour.
The planets in a rowLine the planets up by distance from the Sun or by size. The sizes are true to each other; the gaps are not distances.
The Space Station, probes and satellitesThe Station, 33 probes and telescopes and about 15,900 working satellites, each placed from public orbital data. See the Station's next pass over a city, and the view from its Cupola window.

Fall into a black holeFall into Cygnus X-1, with the light bent the way a black hole bends it.
A nova, a supernova, a star swallowedWatch a nova, a supernova, and a star torn apart as it falls into a black hole.
Meteor showersSeven showers, seen from Earth, from space, or along the orbit of the stream.
Two real eclipsesThe lunar eclipse of 3 March 2026 and the solar eclipse of 2 August 2027: the clock jumps to their real dates.

A real planet as the mapBlue Marble terrain under a live day and night line, drifting cloud, the auroral ovals, and city lights on the night side.
217 countries, 28 indicatorsPopulation, economy, health, research, the internet and more, each figure with its own year and source. Colours show rank, not raw values, so one giant does not wash out the rest.
Build your own indexWeight what you think matters, flip an indicator to less is better, and the planet recolours. The link you share reproduces your ranking exactly.
Country profiles, and two side by sideClick a country for every indicator with its rank, year and source. Pin one and pick another to compare them.
Capitals, cities and airportsA pin for the capital of every country, the cities people know, and about 850 airports. Open one for a photograph and the first lines of its article.
Search that forgivesType a country, city or airport (even its three-letter code), a planet or a satellite. It knows UK for the United Kingdom, forgives a slip of the keys, and works from the keyboard.

Save the places you care aboutA bookmark on a planet, star, country, spacecraft or the Station keeps it on a list in the search box. Signed in, the list follows you to every device.
The clock in your country's timeSigned in with a country set, click UTC under the clock to see your country's time and date instead (the capital's zone, for a country with several). The globe and the sky stay on UTC.
An account only if you want oneNothing is behind it. Signing in keeps your saved indexes and settings (country, panels, layers, music, picture quality) across devices.
Every view is a linkThe address holds where you are, your index and the simulation you are watching, so what you send is what they see.

English and Hebrew, in fullEvery page and every card in both languages, the Hebrew set right to left.
Phone, tablet and computerIt opens on any screen and holds its frame rate by drawing less when it must. The Quality setting keeps the full picture if you prefer.
No trackingNo analytics, no adverts. The page asks no other company for anything unless you ask: Google's button when you sign in, and Wikipedia for a place's photograph.
