Can you name all 88 constellations? If you had that t-shirt you could!! :))))))))
By-the-way, there are also 88 counties in Ohio. Coincidence? I think not. :)))
Not sure if you were outside late the other night, but here in Cleveburg we had the most perfect, clear night. It seems no matter how many times I’m outside late, I love to look up at the sky and search for planets, constellations and stars. And not just the common ones – Big Dipper, Cassiopeia, Orion, but some of the more discrete constellations. I’m lucky where I live – we have a Nature Center, with a spectacular planetarium inside – fun to catch a show or speaker and learn more. I especially like to hear about the children with their oohs and aahhs! I did some digging to see if I could find out more about the more popular constellations and get the stories and myths behind the designs. Seduction, goddesses, queens, romance, serpents and more – Enjoy, and thanks to interestingfacts.com for the details and YouTube for a couple fun tunes to enjoy while you read.

Each constellation of stars in the night sky has a fascinating origin story. From the 48 constellations named by the Greek astronomer Ptolemy in his 2nd-century book The Almagest to the dozens established by astronomers in the 16th and 17th centuries, their names reflect heroic tales from Greek myths, gods and goddesses, and various animals. Today, the International Astronomical Union recognizes 88 principal constellations in the northern and southern skies. Here’s how a few of them got their names.
Here’s a guide to help you track the constellations below: CLICK HERE
Ursa Major
Seven stars make up the hindquarters and tail of Ursa Major, the Great Bear, but you may know them better as the Big Dipper, named for their resemblance to a ladle or drinking gourd. In his book Metamorphosis, Ovid tells of how the huntress Callisto took a vow of chastity to the goddess Artemis, but Zeus, turning himself into Artemis’ likeness, tricked and seduced Callisto. She gave birth to their son, Arcas. When Zeus’ jealous wife Hera got wind of the affair, she turned Callisto into a bear. Years later, Arcas hunted the bear, not knowing it was his mother. To avoid further tragedy, Zeus turned Callisto into Ursa Major and Arcas into the constellation Boötes, the Herdsman.
Cassiopeia
Listed by Ptolemy in the Almagest, Cassiopeia is a constellation named for the infamously vain queen of Greek myth. Cassiopeia claimed that she was more beautiful than the sea nymphs known as Nereids, a bit of hubris that angered the sea god Poseidon. He sent a monster (recorded in the sky as the constellation Cetus) to punish Cassiopeia and her husband, King Cepheus. They tried to appease the monster by offering him their daughter Andromeda (a legend with its own constellation). Cassiopeia is one of the most recognizable and visible constellations in the northern sky: Its five bright stars form a W shape, representing the queen seated on her throne.
Andromeda
Poor, virginal Andromeda had the misfortune of being the daughter of Queen Cassiopeia and King Cepheus. They chained her to a rock in the sea as a sacrifice to the monster Cetus. Things looked bleak for the beautiful Andromeda until Perseus, a demigod hero who had just slain the gorgon Medusa, swooped down from the heavens and rescued her in one of the most romantic scenes in Greek mythology.
Pegasus
Pegasus, the winged horse of Greek legend, has quite the origin story. After Perseus slayed Medusa by cutting off her head, Pegasus sprang from her bloody neck and flew off. Some say Perseus was actually riding Pegasus when he rescued Andromeda, but in myth the horse is more closely associated with the hero Bellerophon. Zeus also employed Pegasus in carrying his thunderbolts. Though the constellation usually depicts only the front half of the horse, Pegasus is the seventh-largest group of stars in the northern sky.
Orion
The famous celestial Hunter is easy to spot in the night sky thanks to the three closely spaced stars of his belt, as well as the bright stars Betelgeuse and Rigel at his right shoulder and left foot. The constellation Orion faces Taurus, the Bull — suggesting that Orion may be based on the Sumerian hero Gilgamesh or the Greek hero Heracles, both of whom fight bulls. Orion boasted that he could kill any beast on Earth, which offended the Earth. The Earth opened to send forth a scorpion, which fatally stung Orion. As a result, the constellations Orion and Scorpio are at opposite ends of the sky so it appears that Orion is fleeing the sky as the scorpion rises in the east.
Hydra
Ptolemy identified Hydra, the Water Snake, as one of the longest constellations in the Southern Hemisphere, as well as the largest. In Greek myth, Hydra is a fearsome water serpent with multiple heads, one of which is immortal. (Five stars at one end of the linear constellation represent the heads of the snake.) The hero Heracles was tasked with killing Hydra as the second of his 12 labors, but every time Heracles cut off one of the monster’s heads, two more grew in its place. Heracles’ nephew Iolaus suggested they burn the necks after cutting them off to prevent them from regenerating. They eventually slayed the beast by burying its remaining immortal noggin under a rock. Heracles then dipped the points of his arrows in Hydra’s blood to render them lethal.
Centaurus
According to Greek mythology, centaurs were half-horse, half-human creatures with a bad reputation as rowdy drunkards, but the centaur Chiron was an exception. The wise Chiron taught medicine and music, and his pupils included Greek heroes like Achilles and Jason. Chiron was mortally wounded when Heracles accidentally shot him with an arrow — one that he had dipped in Hydra’s blood to make its strike fatal. But because Chiron was immortal, he couldn’t die from his injury. Zeus took pity on Chiron and released him to the sky, where he became the constellation Centaurus.
Phoenix
Navigators Pieter Dirkszoon Keyser and Frederick de Houtman accompanied the first Dutch voyage to what is now Indonesia in 1595. Petrus Plancius had trained and instructed Keyser to chart stars in the Southern Hemisphere, and de Houtman served as Keyser’s assistant. They eventually identified 12 new southern constellations and named some after the natural history of the region. The Phoenix, located near the constellation Eridanus, refers to the mythical, multicolored bird that is able to rise from the ashes of its predecessor. The Dutch duo may have been inspired to record the Phoenix after seeing birds of paradise, a group of spectacularly plumed birds native to Indonesia and first described by Europeans in the 16th century.
Leo
When Heracles was made temporarily insane by the goddess Hera, he killed his wife and children. To atone for the murders, he was assigned 12 seemingly impossible labors. The first: to kill the Nemean lion, a fearsome beast with an impervious hide that relished attacking the local villagers. Heracles succeeded in overcoming the lion by gripping him in a bear hug and squeezing him to death. The constellation Leo echoes the lion’s ferocious attitude: A group of six stars are arranged in an arc representing the animal’s front torso and head, preparing to pounce. The brightest star in the arc is named Regulus, meaning “little king.”

Turnover
Most things in, on and under water can be seen. But probably the biggest thing that happens in a lake of any size goes unnoticed by all but a select few people. Interested? Read on, my friend.
I really love looking out my office window and watching the lake. Brilliant sunshine makes it sparkle. Fall cloud formations make me reach for my cell phone camera, and incoming sweeping rain and thunderstorms are a treat every time. I’m not a big fisherman (those of you who know me truly understand why!), so I don’t follow the different fishing seasons, but one thing I learned recently is that my great, beautiful Lake Erie actually turns over – specifically in the spring and fall. A buddy of mine said I should think of turnover much like a dog learning to roll over: As he pushes himself to one side, his underbelly begins to show. It made me think of my brothers on the couch trying to roll over after a massive Kowalski thanksgiving dinner). Wanting to learn more, I jumped online and found some really cool info. For my fishing fanatics out there, I’d love to hear how you adjust to the changing weather and water temperatures (email me at skowalski@khtheat.com). Special thanks to cleanlakesalliance.org, lakes.grace.edu and outdoornews.com for the info.
Lake masses consist of three layers – epiimnion – the upper layer of water in a thermally stratified lake consists of the warmest water and has a fairly uniform (constant) temperature; the hypolimnion – the cold bottom waters, and the metalimnion (or thermocline) layer – a stratum of rapidly changing temperature water.
Fall and spring turnover are natural phenomenon that cause the top layer of the lake to trade places with the bottom layer. This turnover is critical for lake health – like folding chocolate chips into cookie dough (yep, I eat the dough when Jackie isn’t looking!!). In the fall, this phenomenon happens when the temperature in the air drops. The epilimnion then cools to a temperature that balances with the density of the hypolimnion, allowing them to “intermingle.” (The opposite occurs in the spring: the air temperature rises, warming the surface water while the bottom grows cooler).
Water is unique in the way it changes density at different temperatures. Unlike almost all other liquids, water is most dense at 39 degrees Fahrenheit (4 degrees Celsius) and is lighter at both warmer and colder temperatures. In other words, when water reaches the critical temperature of 39 degrees Fahrenheit, further cooling causes the water molecules to become less dense and rise to the surface. This unusual characteristic allows water to form distinct layers within an otherwise uniform liquid. This phenomenon explains why ice forms at the surface and does not sink.
Warmer and less dense water floats on the top of cooler, denser water at the bottom. This allows the lake to mix when temperatures equalize throughout the water column, as water from the bottom of the lake rises to the top, and water from the top of the lake sinks to the bottom. The process allows for oxygen to be replenished and nutrients to be distributed throughout the lake.
The two layers could not intermingle without the wind. As the Fall winds blow and winter approaches, a constant breeze begins to move over the surface of the lake. The wind pushes the surface water from one shore to the other, and as this happens, the hypolimnion moves upward to replace the water that is moving across to the other shore. Once it reaches the other shore it gets pushed downward to replace the hypolimnion that moved up to the other side of the lake. The lake “rolls over” in this way in an ongoing cycle until it freezes over.
In both the fall and the spring, turnover affects three major aspects of the lake environment: oxygen, algae, and phosphorus.
The hypolimnion routinely runs low or out of dissolved oxygen, as decomposition, such as bacteria breaking down organic matter. The turnover breaks down the temperature boundary and moves oxygen-rich surface water to the bottom and oxygen-starved bottom water to the top. Moving dissolved oxygen to the hypolimnion is not only crucial to the lake, but also to the fish who live there.
Fish and most other aquatic critters rely on dissolved oxygen to survive. If too much muck builds up and dissolved oxygen is not replenished, fish will be forced to move toward the surface.
Turnover also helps our lakes clean up harmful bacteria and algae. It carries dead algae down into the depths of the lake where there is less sunlight, helping to prevent algae growth where it is eaten or decomposed at the lake bottom.
Turnover also helps clean up excess phosphorus. As turnover forces iron (which naturally exists in our lakes) toward the hypolimnion, the iron interacts with phosphorus. As it falls to the bottom, the compound is deteriorated by oxygen and anaerobic bacteria. This process is similar to a Ferris wheel as the phosphorus and iron “ride” to the epilimnion and back down to the hypolimnion. Algae blooms are fueled by phosphorus, so the mixing cycle can reduce the conditions for a bloom.
Lake Erie’s western basis turns over frequently, but the larger lake takes more time to cycle. Anglers talk of seeing tiny bubbles on the surface, and also a gray color to the water.
For any angler who ventures out on the water during the cooler temps it can be a make or break time. Finding fish right after turnover can be challenging. Bass, pike, perch, bluegills, walleyes… all may need time to adjust to turnover, but usually the reason fisherman are not catching fish post-turnover is because they’re fishing the same spots as they did before. Baitfish are willing to seek deeper depths, and when their forage goes deep, so do the sportfish. Learn more here.
