  • Stargazing in July 2026: Conjunctions and Meteor Showers

    Today we are going to be looking ahead into the month of July. For the beginning of July, things will still look quite similar to June. However, we are past the summer solstice, so the sky will start getting dark earlier. We still have Venus in the evening, but as we move later in the…

  • Venus Transiting Jupiter (1818) AND Mars Transiting Jupiter (1170)!

    Today we’re not going to be taking a look at the solstice. I have taken a look at the solstice in a few different ways over the past couple of pieces, so we’re going to look at something a little bit different today. We are going to take a look at an event that was…

  • The Midnight Sun From the Edge of the Arctic Circle

    Today we are yet again going to take a look at the solstice, but we are going to look at the solstice in another, slightly different, way. In a recent piece, we took a look at the solstice from the Moon. We’re starting a few days before the solstice, the 16th, so the Moon is…

  • Stargazing in June: The Summer Constellations

    Today we are going to take another look at the night sky for the month of June this year, 2026. We’re going to concentrate on the constellations, the stars, but it is worth pointing out the planets at the beginning of the night. To the west will be Venus, Mercury and Jupiter. They are all…

  • Zodiac and Retrograde Motion: Astronomy, not Astrology!

    Today we’re going to very quickly go over the zodiacal constellations, the constellations that we see in the sky along the path of the ecliptic, which is where we see the planets, the Moon, and the Sun, roughly speaking at least. We’ll start by taking a look at the planets at sunset in June. We…

  • Some Active Galaxies, Quasars and Blazar!

    I hope that some of you got to see the Blue Moon the evening before last. On the sunset of the 31st of May, we had our second Full Moon of the month, the Blue Moon. We are looking just a little bit ahead into June today and so the Moon is going to be…

  • A Cycle of Conjunctions: Jupiter and Saturn in 1226, 2020, 2040, 2060 & 2080!

    Today we are going to take a look at a few conjunctions of Jupiter and Saturn. You may remember from a reasonably recent piece, we took a look at a conjunction of Jupiter and Saturn in 2080, so we’re going to very quickly review that conjunction first. Travelling from June 2026 to 2080 does let…

  • A Sunrise Occultation: The Crescent Moon and the Pleiades

    Today we are yet again looking forward into the coming month of June. Of course, we are very close to June now, so we’re not looking too far into the future, just forward to the 13th of June. Just like the piece before last, we are looking forward to see an event but that has…

  • Stargazing in June: Planets at Sunset and Sunrise, The Milky Way, and the Moon

    Today we are going to take a look at the night sky for June. Last time we looked ahead to the month of June to take a look at Venus and Jupiter having a close conjunction at sunset. Mercury was also up when Venus and Jupiter were up. Even in early June, we have to…
