    Today’s video, we are going to be looking ahead to the end of February to the parade of planets. However, to shake it up a bit, we will be doing so from a few other latitudes. I generally show the sky as it would be seen from here in Ireland, because that is where I

    Having taken a look at Mars at opposition and how Mars enters into a strange, temporary, apparent retrograde motion during that time, we are going to take a look at the Earth doing the same. Of course, to see the Earth at opposition, we need to head to Venus or Mercury. However, before that I

    Lately, we have been looking a lot at the planets. A few videos ago when I spoke about the parade of planets, we followed some of the planets through the constellations that they’re going to be in over the next couple of months. For planets that are closer to the Sun, like Venus and Mercury,

  • Makemake, the Rest, and a Bonus ISS!

    Today are taking a look at one of the dwarf planets, along with some of the candidate dwarf planets, with a digression to discuss the ISS as well.
