Pisces Constellation Astronomy
Pisces Constellation Astronomy – Our Constellation Pick For The Day
A long time ago astronomy wasn’t a science as much as it was an art and type of mysterious magic. But over time theories were tested and recorded by men who wanted answers. This included men like Isaac Newton who realized our sun was a star like any other, and even Ptolemy who way back in 100AD realized our Earth was part of a planetary system. The universe is infinite, which means astronomy is infinite. So a choice has to be made to zero in on a smaller sub-set of astronomy. For our purposes, let’s focus on Pisces constellation astronomy.. How can there be a whole discussion of a constellation and its astronomy? The constellations aren’t just mythical beings imagined by ancient people. Constellations are made up of a large number of interstellar objects like stars and galaxies. While we can’t see many stars in Pisces, we do see a very interesting galaxy. The galaxy M74 is a spiral just like ours, and one that faces us. We see all of it’s arms extending out from its center. That means we can tell it’s a spiral. We can’t just look up and see it, though. It’s just a splotch as seen through most amateur telescopes. However, the spiral details come to life with a professional telescope. When Pisces was first seen the sun didn’t take the same important path through it that it now takes. Pisces (Aries specifically) sees the sun pass through it, over the equator, as it makes its way north. This happens at the Vernal Equinox, the first day of spring for the Northern hemisphere of the planet. When the First Point of Aries was established in ancient times it was east of Pisces. It has, however, drifted into Pisces over the long centuries. This is an example precession, the movement of stars and objects in relation to Earth. The Earth and everything in the universe .

move. Our sun and our galaxy are moving at incredible speeds. The sun and solar system, for example, move at about 220 kilometers per second around the center of the galaxy. Since humans have kept records the solar system has traveled about 1/250th of a complete orbit. The galaxy too, as well as everything in the universe, also moves at a breakneck pace. The constellations have changed over time. Aries and Pisces show this well. Pisces constellation astronomy is ""amazing", after all.
