Using more than half a century of observations, astronomers have discovered that the microwaves coming from the Sun at the minimums of the past five solar cycles have been the same each time, despite large differences in the maximums of the cycles.

Two recent studies show how solar flares exhibit pulses or oscillations in the amount of energy being sent out. Such research provides new insights on the origins of these massive solar flares and the space weather they produce. This is key information as humans and robotic missions venture out into the solar system, farther and farther from Earth.
