  • Féile na Spéire Dorcha agus na Gaeltachtaí

    In almost every video I post to this channel, excepting special videos looking at the Sun and such, I give some comparison between the light polluted sky I see from the city I live in and the superior view a dark sky, with no light pollution can provide. Here in Ireland next week is Dark…

  • Comet 12P/Pons-Brooks: Some Ways to See it, Where and When

    Today, we’re going to be taking a brief and general look at the comet 12P/Pons-Brooks. As with all comets, and most things in the sky, there is a pattern to the names, 12P for being the 12th periodic comet and Pons-Brooks for the surnames of the two astronomers recognized for its discovery. This comet has…

  • An Radharc ón Meánchiorcal: an Anailéim ar lean

    In this video, we will finish dealing with the strange motion of the Sun in our sky by travelling to the equator and observing the analemma, from (almost) the sub-solar point. Of course, we will also be heading forward in time to the equinox, so while that happens at the beginning of the video we…

  • The Spring Equinox at the North Pole, plus the Solstices and More!

Specifically, this is the spring or vernal equinox, the March equinox in the Northern Hemisphere. After months of darkness, the Sun is finally starting to rise.…

  • Mars: How and When to See it and How it Moves in the Sky.

    As you may have seen in some of the recent posts here, Mars is beginning to be visible in the morning sky, but we’re going to have to move to the end of March and beyond before it reaches a good position for observation, at least those of us in higher latitudes. Starting right on…

  • From North to South and East to West: How our View Changes

    In a few videos now, we’ve traveled to other locations to take a look at the sky. Of course, the differences can be pretty big if you travel to the other side of the equator, and if you are hunting down an eclipse or conjunction it will be clear that the view is different from…
