Galileo’s Middle Finger

Galileo’s Middle Finger

In 1737, Galileo’s body was moved from one burial place to another. During the move several of his fingers and a tooth were removed from the body. Gruesome as it seems, this was a common treatment for the bodily remains of famous people.

One of the fingers – his middle one – eventually ended up in a museum in Florence where it sits (standing straight up) on a marble plinth under a glass jar.

Galileo’s science won the day, eventually, and after much suffering. However, thanks to this wonderful museum display, Galileo also got the final word in his epic battle with the powers of the Roman Inquisition – he’s giving them the finger – until eternity.

Constellations of the Zodiac in Order

Learning the Zodiac constellations in order is a great way to get familiar with the ecliptic and the celestial sphere. The Zodiac is not just for astrology – astronomers use the constellations of the Zodiac to name 13 regions of the sky.

Zodiac Constellations zoomed in on Ophiuchus – the “13th” Zodiac Constellation between Sagittarius and Scorpio. The constellation borders (marked red) show how astronomers divide up the sky into named regions.

These are the Zodiac constellations in the correct order from Aries to Pisces.

Memorize the Constellations of the Zodiac in order

This mnemonic (memory device) can help you remember the correct order of the constellations of the Zodiac. This is the best way to memorize the order of the constellations of the Zodiac. It starts with Aries and ends with Pisces.

“All the great constellations look very lovely; shining, (orderly) stars creating animal patterns.”

Alex Davo (original – orderly added by DC)

This sentence is good too – it’s a little bit more romantic.

“A time gone, cowboys loved viewing little stars, (oh) so cold and pretty.”

– Terry Johnson (original – oh added by DC)

Why does the Zodiac constellations list start with Aries?

When astrology was invented it was the same activity as astronomy – observing and cataloging sky objects and their locations) but over the years the two practices have become very different. Astrology is now concerned with how the movement of the skies affects humans while astronomy has become a science. Scientists build knowledge to make predictions about physical events.

During early astrology/astronomy times, the most important thing about the study of the stars was to know where the Sun, Moon, planets, and other solar system objects were located in relation to the steady, orderly background of stars.

Why does the order of the Zodiac constellations read right to left?

The Sun moving “through” Aries into Taurus over a month. Each frame of the animation is about 3 days.

The Sun, Moon, and planets seem to move “through” these 13 constellations in order through the year. Starting with Aries, let’s follow the movement of the Sun against the backdrop of the steady stars. The next constellation that the Sun “moves into” is Taurus. Taurus is to the east (left) of Aries! The Sun appears to move into the next Zodiac constellation about once a month.

We know that the Sun is not moving – that it only appears to move through the sky – and that it is the Earth’s orbital motion that is creating this apparent movement.

Why did we add Ophiuchus to the original 12 Zodiac constellations?

Ophiuchus is a constellation, not an astrology “sign.” However, it is an official constellation that intersects the ecliptic. So, while astrologers do not consider this a Zodiac sign, astronomers include it because the constellation is located on the ecliptic.

The Ecliptic is a path in the sky that solar system objects follow

The solar system objects move generally west-to-east in a small band of the sky – this band of sky is called the ecliptic. All the Zodiac constellations are “on” the ecliptic and all the Sun, Moon, planets and other solar system objects move along the ecliptic over time.

There is another line in the sky called the celestial equator that is an imaginary line the rises from the equator of the Earth. The celestial equator and the ecliptic intersect at a “location” in the sky.

Right now in 2020 that intersection location is “in” the constellation Pisces.

The thin, diagonal line that connects the Zodiac constellations is called the ecliptic. This image shows the ecliptic intersecting with the celestial equator.

However, when astrology was created this intersection point was “in” the constellation Aries.

This image shows the intersection of the ecliptic with the celestial equator in the year 100 BCE.

This was known as the “First Point of Aries.” Astronomer Guy Ottewell writes about this imaginary point in the sky on his website UniversalWorkshop.

Summary

You can learn the order of the Zodiac constellations by using the mnemonic device shown in this article. There is a pathway in the sky that the solar system objects seem to follow. It is called the ecliptic. The Zodiac constellations are the 13 constellations lined up in the sky “on” this imaginary line.

The order of the Zodiac constellations is made because of the way the Sun, Moon, and planets seem to move east-to-west past these constellations in order during the year.

We start the Zodiac names list with Aries because the Zodiac constellations were first named thousands of years ago. At this time, the ecliptic intersected the celestial equator “in” the constellation Aries.

Lights All Askew in the Heavens … But Nobody Need Worry

Lights all askew in the heavens…

Lights all askew... The hilarious headline provided by the New York Times after Einstein's relativity theory proved based on Arthur Eddington's eclipse observations in 1919. Lights all askew in the heavens. Men of science more or less agog over results of eclipse observations. Einstein theory triumphs. Stars not where they seemed of were calculated to be, but nobody need worry. A book for 12 wise men. No more in all the world could comprehend it, said Einstein when his daring publishers accepted it.
New York Times headline about Einstein’s theory of the curvature of space time.

This hilariously-headlined New York Times article describes the results of the observational experiment performed during the 1919 eclipse. It highlights that the expedition proved Einstein’s prediction. But the writer claims that only 12 men on Earth can really understand the result: that light’s path is curved by space time.

The delightful headline reads:Click here to continue reading…

A new star will appear in the sky in 2022

Binary star merge to form a new star - a star in a starAn amazing thing is about to happen! A Star in a Star will be born.

You  can witness the birth of a new star in the night sky.  The new Star already has a birthday: 2022!

According to scientists, the new star will form when two stars that are orbiting each other grow so close that they merge into one.

The new star will appear in the constellation Cygnus. You can see the approximate location marked by a red circle in the Stellarium screenshot here:

The image of the two blue stars on the home page of this Star in a Star site shows what scientists think it looks like now. This impressive video shows an artist’s rendering of the star merge.

In the pair, one star is larger than the other so in the end, there will be a new star…  A Star in a Star.
