  • Orion: The Constellation of the Hunter and its Deep Sky Objects

    In this video we are back to taking a look at something we can see in the sky when the video is published, Orion. Probably one of the most famous constellations in the sky thanks to Orion’s Belt, the three bright stars in the middle, Orion is really coming to the fore in December and…

  • The Night Sky in Ancient Times

    We have used Stellarium to time travel in other videos already. In fact, almost every video looks a little bit into the future, so that we are prepared to take a look at whatever is coming up. In previous videos we travelled years into the future, to watch how the planets will move and to…

  • A Quick look into the December Night Sky; the Winter Solstice and Another Meteor Shower!

    Another month, another preview of upcoming astronomical phenomena! December is a great month for astronomy thanks to the long nights, including the longest night of the year! There is also a meteor shower this month, the Geminids in the middle of the month, nice and close to the New Moon, so the sky should be…

  • Pairs of Stars, Doubles, Binaries and Bigger Groups

    This video is again more on a topic, but it does refer to the state of the sky and positions of objects as they are at the time of the video, late November. Again however, we won’t be looking much at what’s in the sky generally here, we’ll be focused on pairs of stars. Some…

  • Galaxies: How to Find Some and How they Change

    This video is all about galaxies. We won’t go to far into the details of how they form or work, we’ll concentrate on actually seeing some in the sky. For that, we’ll need to take viewing conditions into account. Looking at the sky for late this November, it isn’t perfect. With a Full Moon, there’s…

  • The Constellations of November/December and the Story of Perseus

    We’re back to looking at the sky as it is right now. We are technically looking into next month, but that’s mostly just to keep the Moon out of the way. We’ll be starting in the city, light pollution on its own will already obscure enough stars, the Full Moon would make things even more…

  • Eclipses, Solar and Lunar, the Next Total Eclipses previewed

    Rather than looking at what’s visible in the sky right now, this video goes as far into the future as necessary to see the next eclipses. Eclipses seem rarer than they are, as they are usually only visible from a particular part of the Earth, and they move around. While a solar eclipse might be…

  • Na Príomhimeachtaí i Mí na Sahmna; Dreigechith agus Úránas

    This video is very much an Irish discussion of roughly the same topics dealt with in the last English language video, what we can see in November. However, it isn’t a word for word translation, every video is a little different, even if they broadly deal with the same subjects. For a start, this video…

  • A Quick look at the November Night Sky; Uranus and the Leonid Meteor Shower

    We’re back with another monthly overview! Before we get into this month proper, we did just have a partial Lunar Eclipse which you can read a bit about in previous posts, we also just passed the Opposition of Jupiter. We have discussed oppositions and especially Jupiter in previous videos and posts as well. Jupiter is…

  • The Motions of the Planets and Retrograde Motion

    In this video we’re going to take a look at how the planets move across the sky. For most of the planets that orbit the Sun further out than the Earth, this is reasonably simple. However, for the two planets closer to the Sun than us, things certainly look a little more complicated. This video…
