At a certain distance from the sun, though, that plasma escapes the corona and streams through the solar system as the solar wind, a constant flow of charged particles that pummels the planets, including Earth (SN Online: 8/18/17).

In addition, we'll see auroral activity thanks to coronal holes — openings in the Sun's magnetic field that let its powerful solar wind escape into space.

Two days later, the torrid gas cloud crashed against Earth's magnetosphere — the magnetic field generated by the planet's spinning molten iron core that helps deflect the solar wind and more potent solar jetsam.

Although the bulk of the water mapped in this study could be attributed to solar wind, there were exceptions.

The researchers also found that the corona probably fades into the solar wind between 14 million and 56 million kilometers away from the sun — about 10 to 40 times the sun's diameter.

That previously unseen structure could help solve some of the sun's biggest puzzles, including how the solar wind is born and why the corona is so much hotter than the solar surface.

This barrage is called the solar wind, and it has had a direct role in shaping life in the solar system.

Space weather comes primarily from the sun, which constantly sends particles and energy Earth's way via the so - called solar wind.

Rather than coming from solar wind, the water in those localized deposits likely comes from deep within the Moon's mantle and erupted to the surface in lunar magma.

It floods the nebula with ultraviolet light and blows out a mighty solar wind that's compressing the gas around it, forming the bubble shape of the overall cloud.

That pattern is consistent with implantation via solar wind — the constant bombardment of protons from the sun, which can form hydroxyl and molecular water once emplaced.

The amounts increase toward the poles, suggesting that much of the water was implanted by the solar wind (yellow dots mark Apollo landing sites).

The probe will swoop within 6.4 million kilometers of the sun and take the first direct measurements of the corona — and perhaps figure out more precisely where the corona becomes the solar wind.

Reconnection releases energy and helps move plasma around, so the process could be important to heating the corona and driving solar wind.

What's more, physicists couldn't tell where the boundary between the corona and the solar wind began, which might help to find that missing energy source.

This rotation, coupled with an ever - changing solar wind magnetic field, creates an extremely dynamic Martian magnetotail.

Once these émigrés escape our world, they remain inside a teardrop - shaped region of space surrounding Earth called the magnetosphere (whose rounded end is pointed toward the sun) and are eventually blown away from the sun by the solar wind and into interplanetary space.

«When we compared those predictions to MAVEN data on the directions of the Martian and solar wind magnetic fields, they were in very good agreement.»

The results presented in the thesis show that a stronger solar wind mainly accelerates particles already escaping the planet's gravity, but does not increase the ion escape rate.

Since the Martian magnetotail is formed by linking surface magnetic fields to solar wind fields, ions in the Martian upper atmosphere have a pathway to space if they flow down the magnetotail.

Patterns in the sun's atmosphere that resemble smoke rings may help unravel what drives the solar wind, the stream of charged particles filling the solar system.
