From video description: NOAA forecasters estimate a 60% chance of G2-class geomagnetic storms on April 2nd when a CIR is expected to hit Earth’s magnetic field. CIRs (co-rotating interaction regions) are transition zones between fast- and slow-moving solar wind streams. Density gradients and shock waves inside CIRs often do a good job sparking auroras.
By 2030 solar activity is going to drop by 60%. When that happens, the conditions will resemble those during the last mini ice age in 1645. Solar physicists have observed that the activity of the Sun changes during the 10 to 12 years cycle. The cause of this seems to be the dynamo caused by the fluid that is convecting deep … Continue reading
A serious solar storm has been battering Earth’s magnetosphere, in the wake of a series of solar flares that erupted from a highly active sunspot over the last few days. The flashes of electromagnetic waves from the flares reach Earth in just a few minutes, but enormous bursts of charged particles — known as coronal mass ejections, or CMEs — … Continue reading
Our sun regularly pelts the Earth with all kinds of radiation and charged particles. How bad can these solar storms get? In today’s episode, we’re going to remind you how looking outside of the snow globe can inspire your next existential crisis. You guys remember the sun, right? Look how happy that little fella is. The sun is our friend! … Continue reading
