We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.

Spiral Path of Material

For a planet to be affected by a blob of material being ejected by the sun, the planet must be in the path of the blob, as shown in this picture. The Earth and its magnetosphere are shown in the bottom right.

Disturbances in the solar wind arrive at the Earth within hours to days after a violent event on the Sun.

If the Earth were on the other side of the Sun (the top left of the picture), then the blob would miss the Earth, and there would be no geomagnetic storm or powerful aurora.
