See the system now

The inner solar system, read live — every storm leaving the Sun, tracked from eruption to the hour it reaches Earth.

Where you actually are

The Sun doesn't stop at its surface. It blows a bubble — and every planet orbits inside it.

That bubble is the heliosphere: a vast pocket of solar wind that reaches far past Pluto. Earth doesn't sit near the Sun — it sits within its atmosphere. "Space weather" isn't out there somewhere. It's the weather of the room you're standing in.

Most people never picture it, because nobody ever drew them the map. This is the map — the inner system, live.

Tracked from the moment it erupts

When the Sun throws a storm, it takes days to cross to you.

A coronal mass ejection is a billion tons of magnetized plasma flung off the Sun at a million miles an hour. It doesn't arrive instantly — it spends one to three days crossing the gap. We catch each one at eruption from NASA's DONKI catalog and follow it down the Parker spiral until it reaches Earth.

Not one number. The whole inner system, watched.

CMEs inbound

Each ejection, from eruption to arrival.

The Parker spiral

The curved path the solar wind actually takes.

Solar wind

The stream carrying it all, speed and density.

What it means, in plain language, daily.

Where the picture comes from
The Parker spiral

Because the Sun rotates, its wind doesn't fly out in straight lines — it winds into a spiral, like water off a spinning sprinkler. That curve decides which way a storm is really aimed.

DSCOVR at L1

A spacecraft parked a million miles sunward of Earth, where the Sun's and Earth's gravity balance. It tastes the solar wind before we do — an early-warning buoy in the dark.

Real instruments

Eruptions come from NASA's DONKI space-weather database; wind speed and density from DSCOVR and NOAA — the same feeds mission controllers watch.
