    As we continue to move later in the month, we are now just past the date where a lot of the cool stuff happened. We are just past the 17th, a little, which is around the time that Mercury had its greatest elongation and it’s the date where the Leonids would have peaked. AS such,…

  • Dark Matter and Modified Newtonian Dynamics: A Very Brief Introduction

    Today, we are going to briefly talk about dark matter and dark energy and Modified Newtonian Dynamics. Unfortunately, these are not things that I can show. Then again, I never really show anything in these written pieces, they’re all tell, but even in the attached video I cannot show dark matter. Dark matter, if it…

  • Planet X or Planet 9: The Mysterious Hypothetical Planet

    Today we are going to bet talking about a planet that is still hypothetical, planet nine or Planet X, the next planet that is yet to be discovered in our solar system, if it exists at all. Before we get into that, I have made a slight adjustment to the format of my recording. For…

    Today, we will be taking a quick look ahead to the upcoming month of November to see what we can see in the sky. As I have mentioned frequently in a few of the recent videos, such as when we were discussing comets and then nova that was supposed to occur in September, predicting the…

  • An Spéir ar Oíche Shamhna! / The Sky on Halloween!

    For this piece we will be looking at the sky for Halloween, and a little bit into November as well. The attached video is in Irish, but with English subtitles if you need them. As such, a couple of things do get lost in translation. The Irish for Halloween is “Oíche Shamhna” or Samhain Night.…

  • Eris: The Dwarf Planet that Caused all the Strife and Discord

    Today we will be continuing our look at various objects in the Solar System, which now means continuing with dwarf planets. I do of course want to continue reminding people about the currently visible comet, C/2023 A3, as well. It’s still there, just barely visible as we come to the end of October. This is…

  • No Nova? Corona Borealis and the Blaze Star

    I am going to start with potentially a little bit of bad news. It’s not very bad news, but at the same time it’s not great, I am certainly a little disappointed. It no longer looks like we will see a new star in the sky this year. For a while, it seemed likely that…
