Why the Zodiac Still Matters to Astronomy
Ғылым және технология
To understand astronomy, astrology might actually not be a bad place to start... Although scientists certainly haven’t proven that being an Aries makes you more impatient or a Libra means you’re wise, the constellations in the zodiac have unlocked hidden secrets of the stars for centuries. In this episode, we’ll explore the ecliptic line and how it is still significant to astronomers today.

Here’s how it works. If you could see all of the stars during the day, over the course of a year you’d be able to see the Sun slowly moving along a path from one constellation to the next. That imaginary path is called the ecliptic; and it’s arguably one of the most important coordinate systems in astronomy.
What makes the ecliptic line so useful is how it shows the plane of Earth’s orbit around the Sun and our place in the solar system.
Because all of the major celestial bodies in the solar system orbit the Sun in a similar way, they’re on or near the same flat plane of the ecliptic. That’s all the planets, and even the Moon. While some differ by a few degrees from the line, they're all essentially there. Another reason zodiac constellations became so famous throughout history, is that we always see the moon, planets and eclipses near them.

Dates of the sun’s entry into the zodiacal constellations for 2021
“You might know that the real sun in the real sky does not appear in front of a constellation of the zodiac within the same range of dates you’ll see listed in astrological horoscopes. That’s because astrology and astronomy are different systems. Astrologers typically indicate the sun’s position with signs while astronomers use constellations. We were asked for a list of the constellations that fall on the ecliptic with the exact degrees. And we’ve located this information in Guy Ottewell’s Astronomical Calendar 2021.”
earthsky.org/?p=320593
The First Validated Planets Found by K2
“A majority of all exoplanets known today were discovered by Kepler. After the spacecraft’s loss of a second reaction wheel in 2014, the mission was renamed K2 and embarked on a new survey of the ecliptic plane, divided into campaigns of roughly 80 days each. We have presented 104 validated planets discovered using K2 photometry and supporting ground-based observations. Of these, 64 are planets validated here for the first time.”
www.lpl.arizona.edu/~ianc/doc...
Why Don’t the Constellations Line Up with the Astrological Dates?
“The astrological signs were identified and connected to the calendar about 2500 years ago. However, since that time, the timing of Earth’s seasons has shifted. This is partly due to the fact that Earth wobbles a little like a top, making its axis point in different directions at different times. This is a predictable cycle of change over a period of about 23,000 years.”

You can probably point to the Big Dipper, Orion's Belt, and your astrological sign in the stars.
But what would the constellations look like from another solar system? And will any of Orion’s stars ever become black holes? In Seeker Constellations, we'll explain the science of the universe’s most famous stars and dive into the culturally significant stories behind them. Most importantly, we’ll provide a guide to where you can see these incredible constellations for yourself!

Can you edit to fix the solar system @ 2:03 onward? Planets are orbiting in the wrong direction and at the wrong relative speeds (e.g. looks like Saturn is travelling faster than Jupiter). I get that it's an orrery, so I'm not bothered by the distances/sizes.

Use the moon and or sun trail (zodiac -- i.e "animal trial") in your locale; that would be towards the south in the N hemi (e.g out of your back door after dinner). Everything "barrels" overhead from east (rising sun) to west. "Light pollution" makes this difficult in some ways BUT easier in others (fewer stars to overwhelm you). Very local trees too can box you in. When you see a bright star on that trail that DOESN'T twinkle, that's a planet. Use the net to or an astronomy prog (stellarium celestia) to investigate what it was. Learn more as the zodiac constellations (and their neighbors) rise in the east in your locale seasonally (e.g out of your back door after dinner).
I'm just confused on how they find a whole animal in 3 dots, or 4 lines in a million of them

Great topic! Idea: 12 mini series on each of the constellations, how to find them with just your eyes, and each of their more in depth relevance to science
The Signs of the Zodiac are entirely different from the Constellations that lie on the ecliptic. The 12 Signs are 30° slices of the ecliptic starting from the Vernal Equinox Point (where the ecliptic and the celestial equator meet). This Ecliptic Coordinate System was established some two thousand years ago by Ptolemy in Alexandria and is still used today. The Signs were named after the constellations as a legacy from the past. However, it was known at the time of inception that the Signs of the Zodiac (which corresponded with the Earth’s seasons) would gradually move out of alignment with the Constellations due to the precession of the Equinox. So, the Signs of the Zodiac are a mathematical construct. The position, shape, distance and size of the Constellations that lie on the ecliptic including Ophiuchus are not relevant to the Signs of the Zodiac.

Perhaps to us today, a constellation doesn't look like what someone 4000 years ago thought, our imaginations may not be less than that farmer back then, but we imagine at a different level. We have learned so much since then, and it all started with OBSERVING the world and sky around us, day and night.

Hi Sarafina! Loving the show. Could you cover the history of measuring astronomical distances, for example using stellar parallaxes? :-)
I'm so into this!
Welcome to the Seeker group New member!! Woo Hoo !!!🥳
The necessity of having zodiac patterns in the sky allows us to communicate over a wide distance of time and space the location of stars and how they have moved through the sky over over the millennia. Constellations and having an intimate knowledge of their movement through the sky throughout the year facilitated not only Marine navigation it also aided in terrestrial navigation when geographical renderings were either incomplete or nonexistant.
One the first asterisms I was taught to find with binoculars was the "coat hanger". A future topic might be interesting things you can see with binoculars

Use of constellation in maritime navigation/Importance of constellation to travelers
We only observe the universe one moment at a time. But what if the actual size of the universe is the sum of it's size at every moment from beginning to end? The universe that exists now is not the same universe that existed a second ago. Like a stack of photos we only see one at a time but the whole stack makes a movie. Maybe our experience of time is us moving between universes? Upon further consideration in this framework you wouldn't necessarily need a third dimension of space it would arise as a consequence of moving through a multiverse.
really cool

The star's alignment against particular dates & calendars has changed, the stars themselves will look the same for a very long time.
Ancient astrological data may better support more recent research if retrospectively corrected for astronomic progression(?), even though it may remain relatively more challenging to be considered a true "science" since applying the scientific-method and statistical analysis to sufficient study populations for double-blind or triple-blind relationships between causes and effects (or even analyze via standardized epidemiological protocols) , not to mention factoring in considerations such as: gender, spaceweather, anthropogenic EMF, altitude, genetic neuropsychologic predispositions, cultural & socioeconomic influences, relocation to distant geographic regions, and distant sources of regional activity (e.g.: dynamics of an attack by a country under the influence of a remote astrological environment), Etc.. Nevertheless, I consider it important to contine learning, researching, and recording as much astrological data as possible, esp as A.I. & supercomputing (& on-going detection of characterizations of previously unknown energies, such as quantum entanglement, dark matter, Etc.) developments are accelerating the scientific communities' abilities to randomly search & compare databases for objectively recognizing patterns and may eventually discover that the locations of astral bodies in space-time may indeed influence biological organisms (formation of organelles, cells, tissues, organs and neural networks of organisms, and also growth, maintenance, and functions going forward). Insofar as our brain and nervous system as well as our endocrine system/hormones have been proven to influence perceptions, feelings, and personality, why rule out that planetary influences (via their own gravity, direct and indirect interactions w/gravitational fields of other astral bodies, effects on any number of wave forms &/or various combinations of collective flows/streams travelling through and around our solar system, emission of sound waves &/or light rays (Etc.)? In general, I believe that science benefits from as much collaboration between fields of study as possible because: the perspectives from which various knowledge can be obtained when considering any event of interest seem nearly limitless, the interconnectedness of events necessarily impacts our interpretation of artificially isolated events when applying the knowledge acquired to the cosmos beyond a region of controlled conditions, and that the growing total body of knowledge across recorded human history has surpassed the human brain's ability to even retain no less cross reference, and I believe that pseudosciences incl Astrology should be included for consideration since no theories are relied upon as factual truths unless & until proven, Etc.

Talk more about how the dates are months off from the horoscopes
When playing with Stellarium we discovered the feature showing different "cultures" for constellations - some of the images there are really beautiful. Since many of the images are not available online, i did a super simple website to showcase them - etoiles.netlify.app/. It would be great if you could spend a bit of time talking about how each culture saw the stars a bit differently. Also, it would be great to show more cultures - ie there is not much about how Africa saw the constellations in Stellarium nor online ...
0:35 they do determine our personalities and here is why. because people believe in them, when people believes in horoscope they think and act accordingly to their believes, just like religions. therefor more people believe in horoscope more accurate it is.
