These ions are mostly the positively charged ions (protons) of hydrogen atoms, the most common element in the solar wind. Also, related simulations show that when ions in the solar wind collide with ancient, 'fossil' magnetic fields in certain areas on the lunar surface, they are reflected back into space in a diffuse, fountain-shaped pattern. The simulation reveals this electric field can generate electron beams by accelerating electrons blasted from surface material by solar ultraviolet light. Farrell is lead of the NASA Lunar Science Institute's Dynamic Response of the Environment At the Moon (DREAM) lunar science center, which contributed to the research.Ĭomputer simulations help explain these observations by showing that a complex electric field near the lunar surface is generated by sunlight and the flow of the solar wind. William Farrell of NASA's Goddard Space Flight Center in Greenbelt, Md. 'An upstream turbulent region called the 'foreshock' has long been known to exist ahead of the Earth's bow shock, but the discovery of a similar turbulent layer at the moon is a surprise,' said Dr. ARTEMIS stands for 'Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun'. 'With ARTEMIS, we can see the plasma ring and wiggle a bit, surprisingly far away from the moon,' says Halekas.

NASA's ARTEMIS mission has now also seen both the electron beams and the ion plumes, plus newly identified electromagnetic and electrostatic waves in the plasma ahead of the moon, at much greater distances from the moon. The electron beams were first seen by NASA's Lunar Prospector mission, while the Japanese Kaguya mission, the Chinese Chang'e mission, and the Indian Chandrayaan mission all saw ion plumes at low altitudes. These phenomena have been seen as far as 6,000 miles above the moon and generate a kind of turbulence in the solar wind ahead of the moon, causing subtle changes in the solar wind's direction and density. 'We've seen electron beams and ion fountains over the moon's day side,' says Dr. Many energetic particles in the solar wind, represented in gold, are deflected by Earth's magnetic 'shield.'

Earth is in the middle of the image, surrounded by its magnetic field, represented by purple lines. Recently, however, an international fleet of lunar-orbiting spacecraft has detected signs of the moon's presence 'upstream' in the solar wind.Īrtistic rendering of the Earth's global magnetic field, with the bow shock.

'It was thought that the solar wind crashes into the lunar surface without any warning or 'push back' on the solar wind,' says Dr. Unlike Earth, the moon is not surrounded by a global magnetic field. The magnetic 'bubble' surrounding Earth also pushes back on the solar wind, creating a bow shock tens of thousands of miles across over the day side of Earth where the solar wind slams into the magnetic field and abruptly slows from supersonic to subsonic speed. When a particularly fast, dense or turbulent solar wind strikes Earth's magnetic field, it can generate magnetic and radiation storms that are capable of disrupting satellites, power grids, and communication systems. The solar wind is a thin stream of electrically conducting gas called plasma that's constantly blown off the surface of the Sun in all directions at around a million miles per hour. While there is no link between the moon and human lunacy, spacecraft and computer simulations reveal that the moon does indeed have the cosmic kind a far-reaching, invisible influence on the solar wind.

We know the moon - Luna - effects us, its gravitational pull creates ocean tides and many ancient cultures thought it could also affect our health or state of mind.

The word 'lunacy' is derived from the longheld belief that people act a little crazier during a full moon.
