Today is the June solstice, the start of summer for half of the world and of winter for the other.
The Northern Hemisphere dips toward the sun, basking in its warmth for longer than on any other day, as the chilling Southern Hemisphere swings away, all thanks to Earth’s axial tilt of 23.5 degrees.
What better moment to ponder the sun, that explosive ball of plasma that makes our existence possible?
At more than a million degrees, the roaring outer corona is hundreds of times hotter than the solar surface beneath it, and researchers hope that a deluge of solar data over the next decade will help explain why.
Next summer, NASA plans to launch the Parker Solar Probe, a spacecraft that will investigate the plasma puzzle by coming as close as four million miles to the surface by 2024 — almost 90 million miles closer than we are.
Protected by a special heat shield, the craft will observe the sun’s magnetic field, its electrical field and the energetic particles from the solar wind.
“It will revolutionize our understanding of the sun,” said Eric Christian, a scientist on the project. “It’s the first time we get to go where the action is.”
