The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV.

The magnetosphere is shaped that way because of the near-constant flow of solar wind and magnetic field from the Sun-facing side. Earth’s and other magnetospheres deflect charged particles away from the planet — but also trap energetic particles in radiation belts.

When the solar wind encounters Earth, it is deflected by our planet’s magnetic shield, causing most of the solar wind’s energetic particles to flow around and beyond us. This region that meets and blocks the solar wind is called the magnetosphere.

The material in the sun and its atmosphere — as well as the material in Earth’s ionosphere, aurora and fluorescent lights — are all plasmas. Plasmas are so incredibly hot, that the electrons leave their atoms, making it essentially a gas of charged particles.

The Sun is a self-sustaining dynamo that converts convective motion and differential rotation within the Sun to electric-magnetic energy.

The Sun is a magnetic star. As these magnetic fields emerge through the Sun’s visible surface (the photosphere), they form sunspots and other active regions and create complex and dynamic plasma structures in the Sun’s upper atmosphere (corona).

The Sun has a very large and very complex magnetic field. The magnetic field at an average place on the Sun is around 1 Gauss, about twice as strong as the average field on the surface of Earth (around 0.5 Gauss).

The world’s most powerful magnets: The two biggest magnets reside at Los Alamos National Laboratory in New Mexico and Florida State University (FSU). The two sister laboratories have magnets that can reach 100 and 45 tesla, respectively. By comparison, junkyard magnets — the ones that lift cars — are about 2 tesla.

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

While the moon has no magnetic field of note today, recent evidence from rock samples brought back by the Apollo missions show that between 4.2 and 3.4 billion years ago, when the moon was more than twice as close to Earth as it is now, it did have a magnetic field that was at least as strong as Earth’s present …

The Moon doesn’t have an atmosphere or air for humans to breathe. But its surface – which is covered by a substance called lunar regolith (Moon dust!)

Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.

Does a compass work on the Moon? A Theoretically, yes, but ”you wouldn’t want to depend on getting back home using it,” said John W. Dietrich, curator of lunar samples at the Johnson Space Center, Houston. On Earth, a compass needle points to the North Magnetic pole.

Compasses work using magnetic fields. As you leave the Earth and move into space the magnetic field will get weaker. Even though the field is weaker, the compass can still align with it meaning that a compass on the International Space Station would still be a reliable guide to the North Pole.

Fire can not be lit on the moon because there is no oxygen there. without one of these elements it is impossible to lit fire.

The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun’s light, making it appear bright in our sky.

Originally Answered: Why doesn’t the Sun shine on the Moon as it shines on the Earth? Moon doesn’t have atmosphere and so there is no scattering of light. And so the blue light does not scatter and spread to form a day like shine on Moon .

In the daytime we see the sun shine. Our sun is a very bright star. The sun’s bright light blocks out other stars. It blocks out stars that are not as bright.

The maximum solar irradiance on Mars is about 590 W/m2 compared to about 1000 W/m2 at the Earth’s surface. For any latitude and any date you can determine if the intensity of sunlight on Earth is less than, or greater than, the intensity of the sunlight on Mars.

Mars is very cold. The average temperature on Mars is minus 80 degrees Fahrenheit — way below freezing!

At present, Mars’ water appears to be trapped in its polar ice caps and possibly below the surface. Because of Mars’ very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
