  • Exoplanets and Where to Find Them

    Firstly, this video has a terrible visual artifact around the webcam. I believe I know what went wrong and should be able to prevent it in future videos, but I’d rather post something than skip a week, so here we are. I have updated the version of Stellarium that I am using. Up until recently,

  • An Oíche is Faide agus Pláinéid timpeal Réaltaí eile

    Welcome back to another Irish language video about astronomy, I endeavor to put out at least one Irish language video a month on this channel/website, and given the month that we are in, this one looks first at the longest night. In Irish, the month of December is “mí na Nollag” and Christmas is “Oíche

  • Minor Objects, Meteors, Asteroids and a Dwarf Planet in the Asteroid Belt!

    The Geminid meteor shower is upon us, or very nearly at least. I mentioned the Geminids in our overview of December, and there is a whole video dedicated to meteor showers as well. However, unlike many other meteor showers, which are caused by comets, this one is caused by an asteroid called Phaethon or 3200

  • A Stellarium Feature, Telescopes, Binoculars and Oculars

    All of the videos I make use Stellarium, we’ve seen how it can transport you through time and to other planets, and we’re going to play around with one of its features in this video, the ability to simulate the view from a telescope. Telescopes are simple in principle but of course the details can

  • 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
