It's true that planets usually don't flicker, or twinkle (or scincillate, as astronomers like to call it). The reason is that they are close enough that they are actually seen as a disk with a larger diameter than the atmosphere can "wash out" (the seeing disk). Stars, on the other hand, are point sources, and this point jumps back and forth on the sky, as ...

I know it's a bit late for the UK eclipse, but for future reference: Welders goggles do not cut out the same frequency of light that Mylar/Black Polymer eclipse glases do. Arc welding glass #14 is much darker than brazing welders glass but there is no guarantee that they will block the Sun's ultra-violet and infrared rays. The problem is there are no ...
