We love our sunshine in California and on Dec. 21, we will have the least daylight in 2019. The winter solstice has a mere 9 hours, 55 minutes of light so we had the bright idea to give you a sun fix with a look at NASA’s latest solar mission.

NASA’s Parker Solar Probe has gone closer to the sun than any man-made object and is capable of withstanding temperatures up to 3,000 degrees (volcanic lava is between 1,300-2,200 degrees).
