I Am Not an Astronomer

I am not an astronomer, though a friend claims that I play one online. I suppose I know a bit more than the average person, but really I just do my research.

If you look online at places such as www.astronomy.com/observing/, you can see what is coming in the sky and universe this week or for the month. (Here is June)

The image above is a logarithmic scale conception of the observable universe with the Solar System at the center. Then come the inner and outer planets, the Kuiper belt objects, Alpha Centauri, Perseus Arm, Milky Way galaxy, Andromeda galaxy, nearby galaxies, Cosmic Web, Cosmic microwave radiation, and the Big Bang’s invisible plasma on the edge. Distance from Earth increases exponentially from the center to the edge. Celestial bodies are shown enlarged to appreciate their shapes.

The annotations are in Arabic, which seems appropriate because Arab astronomers translated the names of stars from Greek to Arabic in the 8th–9th century, and then again from Arabic to Latin in the 12th century. These Arabic names are the basis for most of the names of the brightest stars.

The Arabic astronomers also added their own names based on traditions passed down by nomadic ancestors who used stars to guide them through the deserts of the Middle East. Over 200 stars visible to the naked eye have names that come from Arabic. Some names are fragments of longer Arabic names, which were often shortened to fit on medieval astronomical measurement devices. Other names have been distorted beyond recognition over time due to translation and copying errors.

In Psalm 147:4, it says “He telleth the number of the stars; he calleth them all by their names.” But the only body today which can give names to astronomical objects is the International Astronomical Union (IAU). Of course, that hasn’t stopped commercial firms from offering individuals the opportunity to “name” or “sponsor” a star. These names will be recognised by no one but you. You don’t need a company or the IAU to unofficially name a star after yourself or create a constellation in the sky. I did that with my sons many years ago. The important thing is to look up at the night sky and appreciate all that you can see and feel the wonder of the universe.
