    What is Celestial Navigation?

    June 29, 2020 /

    We’ve been dreaming of the stars for longer than we can remember, staring up at the twinkling lights that fill the night sky and wondering what they are. We’ve even written songs about them. Centuries ago, before the advent of GPS, explorers and adventurers relied on celestial navigation to help them map a path to their destination. What is celestial navigation, how does it work and when was it relied upon? Contrary to what its name suggests, celestial navigation doesn’t mean we’re navigating our way through the stars. Instead, from here on earth, navigators could use the stars to plot a course — even across the ocean where there were…

    The Resurgence of Astrology

    November 23, 2019 /

    Astrology: Capricorn, Pisces, Scorpio… daily, weekly and monthly horoscopes. You know the thing. It’s easy to confuse with astronomy which is more telescopes and rocket launches. While an astrologist might argue they are the same thing, an astronomer will vehemently refute this. There has always been a lot of doubt and scepticism about the validity of astrology. Can the stars really predict what you will do and the problems you will encounter this month? That is debatable. Perhaps an astronomer would say there is no scientific evidence, but an astrologer will point to endless anecdotal evidence. Which side of the argument you fall on doesn’t change the huge resurgence in…

    On October 8 we will witness the Draconids meteor shower. It is a minor meteor shower producing only about 10 meteors per hour originating from dust grains left behind by comet 21P Giacobini-Zinner, which was first discovered in 1900. The Draconids is an unusual shower in that the best viewing is in the early evening instead of early morning like most other showers.

    Aquila Constellation

    July 11, 2011 /

    Aquila is a constellation that lies just a few degrees North of the celestial equator. It is best seen in the summer because of its apparent location along the line of our galaxy. This is why many clusters and nebulae are found within its borders. It was one of the 48 constellations described by Greek astronomer Ptolemy in the 2nd century.

    Aquarius Constellation

    June 30, 2011 /

    Aquarius is one of the oldest of the recognized constellations along the sun’s apparent path, also known as the zodiac. It was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. Its name is Latin for “water-bearer” or “cup-bearer”.

In illustrations, the brightest stars of Aquarius are represented as the figure of a man, while the fainter stars barely visible to the naked eye are represented as…

    Introduction to Astronomy – Apparent magnitude

    November 21, 2010 /

    Yesterday I have used the term “apparent magnitude” in my article about the Antlia Constellation. Since some of you may be new to astronomy, I decided to start a new series of articles to introduce you to the topic. Each article of the series will focus on one scientific term used in astronomy. The series will not be a regular one: I will only write an article after using a complicated astronomy term that some of you would need me to explain. Definition The apparent magnitude (noted as m) of a celestial body is a measure of its brightness as seen by an observer on Earth. Since the apparent brightness…
