This beautiful photo of the Aurora Borealis was captured by my friend Yvonne Wong in Alaska recently. The aurorae are more frequent around the two equinox periods each year because the N-S component of the Earth’s magnetic field is reduced and less able to fend off the solar wind. Hello, Spring Stargazers! Here are your…
