We are now used to large-scale meteorological forecasts that are quite accurate for about a two-week timescale. Scientific weather forecasting originated about a century ago, with the term “front” being associated with the First World War. Meteorological prediction is based on a good knowledge of underlying theory, codified into massive computer pr...
Most space weather originates from the sun. Its outermost atmosphere blows into space at supersonic speeds, although at such low density that interplanetary space is more rarified than what is considered a vacuum in our laboratories. Unlike winds on Earth, this solar wind carries along a magnetic field. This is much smaller than Earth’s own field t...
Unlike the detectable, sometimes even visible, water content in the atmosphere that is so important in meteorology, the magnetic field of gas ejected from the sun, including in hot and denser clouds from explosions, is almost impossible to detect from afar. The effect of an interplanetary cloud is greatly enhanced if the direction of its magnetic f...
By the gravitational laws of orbits, a satellite continuously monitoring magnetic fields by direct measurement must sit about a million miles (1.6 million kilometres) from Earth, between us and the sun a hundred times further away. A magnetic cloud causing minor space weather effects usually takes about three days to come from the sun to Earth. A t...
Feb 26, 2021 · Space. Solar storms can wreak havoc. We need better space weather forecasts. Scientists are expanding efforts to probe outbursts from the sun and understand their occasionally Earthbound paths. A ...
May 20, 2021 · Space weather could be extremely dangerous for any astronauts flying to the moon or trying to live and work on a lunar outpost at the surface. Life support systems and power could shut down, and ...
