Great channel and content. I'm currently enjoying your "Stargazing Basics" course and wanted to let you know that at 2:55 in this video (Motion of the Earth and Sky) the intro section is repeated. I assume this was due to an accidental video editing error, so wanted to let you know. Thanks. Keep up the great work!
I have a question. I was trying to figure out what time of year it was on earth. Based on the tilt relative to the sun, it looks like winter for the northern hemisphere, and summer for the southern hemisphere And so I had figured it night be sometime in February? I had assumed it was after winter solstice, and before vernal equinox - but it sounds like maybe I had things flipped? It seemed like the video indicated Ɣ as being associated to the autumnal equinox and Ω the vernal equinox - is that correct?
Sure thing. I have two videos on Orion: Short version: bit.ly/OrionConstellationBasicsVideo Long version: bit.ly/OrionConstellationAdvancedVideo Orion is best seen in the winter months. The three belt stars and the diffuse nebula underneath the belt stars are both defining features of this constellation. If you can find Orion in the sky, it can help point you towards other constellations.
Ever heard of the Zodiac signs? Like, are you a Leo, or a Capricorn? Putting aside the mystical/divination part, the reason there's a Zodiac and astrology is because Earth turns around the Sun through the year, causing changes in the constellations that appear by night month after month. This was observed since antiquity, same as the fact that some of those stars traced a "loop" on the sky in the course of some time. The ancient Greek called them "planets," meaning "wanderer." For centuries, astrologers/astronomers (for long, there wasn't a real difference) tried to fit their belief of Earth as the center of the Universe with everything revolving around it with what they watched in the actual sky: *it did not match.* It was in 16th century that mathematician and astronomer Copernicus figured out the truth (up to that point): the Sun is at the center, Earth rotates around it (hence the Zodiac and planets doing their loop: apparent retrograde motion from our point of view), and Earth spins (hence day and night). Later came the discovery that the Sun is not at the center of an Universe way larger than what the ancients could see without telescopes. All of which has been proved to death by generations and generations of astronomers and mathematicians. I highly recommend you to watch the Astronomy and History of Science courses at the Crash Course RUclips channel. Good luck. ✌
Thanks for a wonderfully educational channel. I notice on the "axial tilt" image you have the north magnetic pole marked as "south magnetic pole". Thought I'd mention it as it may confuse some people.

Nice explanation of every single aspect 👍 9 and subbed.

Yeah, I'm the 1000 sub to the channel.
Nice video. But isn't it true that the Earth's axial tilt is what creates the illusion that the sun is passing through the sky.
Can you explain how you recognized orion?i didnt get that.
Sure thing. I have two videos on Orion:

The earth isn't spinning. The star's are.
Stars do rotate, and so does the Earth.
The stars don't spin around earth, dipwad

Why the extra one day is added in Feb?
It is because the length of time for an Earth year is 365.25 days....so an extra day is added to February every 4 years.
the calender is wrong not the stars the original calender was lunar weeks

beware of flerfers 😉
Have You considered that Our system is geo-axial binary?
