  • Possibly the Longest Eclipse: July 2186

    Today we are finally going to look 160 years into the future, plus a few months, to catch what looks like the longest eclipse we’re ever going to get, very close to the hypothetical maximum duration of an eclipse. Just before we get into it, here in Ireland and across a lot of the northern…

    Today we are going to be discussing the shape of various objects in the sky. Unfortunately, it can be tricky to actually see these shapes, especially with stars, but we will at least be discussing them.
