  • Uranus: A Closer Look at a Barely Visible Planet

    Continuing my series taking a closer look at the planets, we are now onto Uranus. In previous pieces I have covered mercury, Venus, Mars, Jupiter and Saturn, so you can take a look back to see those if you’d like. The Earth, of course may fall a little outside the realm of astronomy, and for

  • The Moon and Constellations in July: No Telescope Needed

    Given that the past couple of videos heavily featured objects that at least require a telescope to see, I decided that in this piece I’d go through some of the things visible to just your eyes in later July. Telescopes and binoculars are, of course, wonderfully useful tools for astronomy and reveal a lot that

  • Meteor Showers in July: How and When to Observe, and What to Expect

    I only recently put up a piece providing a look ahead to the month of July, but it was just an overview, so I’m going to cover one thing that I left out, the upcoming meteor showers. Meteors, of course, can be tricky to see. Looking at the sky from a city, especially if the

  • How the Sky Looks Using Binoculars: Galaxies, Nebulae, Planets and even Moons!

    In most of my videos, I zoom in as far as is necessary to see whatever details I want to talk about. In real life, you are usually limited by the magnification of whatever instrument you are using, be it a telescope a binoculars. People don’t often associate binoculars with astronomy, instead binoculars normally get

  • Spiral Galaxies: You’re in One and How we Know

    Today we are going to take another look at galaxies. We’ve looked at galaxies before, and you can take a look back through my archives for some examples, but thankfully they are a big topic, so there is plenty to talk about. We are going to be taking a look specifically at spiral galaxies like

  • Saghasanna Pláinéid nach bhfuil Againn: Iúpatar Te agus araile

    In a recent video, I discussed the differences between the gas giants like Jupiter and Saturn and the ice giants like Neptune and Uranus. These two types of planets both contrast with the rocky planets in our solar system. This gives us three types of planets, though the gas and ice giants are commonly lumped

  • A Look Ahead to the Sky in July

    As we approach the end of June, we’re going to take a look ahead to what’s coming in July. Of course, at the very beginning, the sky won’t look too different, but we will look through the whole month. We will still start at the beginning of the month and the beginning of the night,

  • Famous Star: Real Stars in Science Fiction

    In the last piece, we took a look at some stars that were famous for moving quickly. The only one visible to the naked eye, 61 Cygni, is pointed out a the start of this video as well. Even though it has some unique features, it isn’t particularly well know. Some stars are incredibly famous,

  • Fast Moving Stars: High Proper Motion

    As the title says, we are going to be looking at fast moving stars, specifically stars with high proper motion. This means stars that look like they’re moving quickly in our sky, the ones we can tell are moving fast. Usually, when we’re looking a the sky, we treat the stars as a fixed background,

  • Where you can See a Different Sky More Easily

    Today, for this issue or installment, I decided to take a look at the sky from a couple of different locations and compare the kind of view that you can get. This is something that I regularly do as the sky does look from different places. Often, my focus is on comparing dark skies to
