Neil deGrasse Tyson's Guide to Skywatching
720,467
Published 2024-04-02
Discover the sun’s path along the sky, how far it travels every day, and what Chuck thought AM and PM meant. We explore using right ascension and declination to create coordinates for stars. How does Earth’s precession get factored into this coordinate system? Learn about lines like the meridian, celestial equator, ecliptic, and the galactic equator. Plus, find out why the Zodiac signs are off an entire constellation.

Do you have a favorite constellation?

I really enjoy the chemistry between NDT and Chuck Nice. While Chuck is a comedian, not a scientist, he is intelligent and well informed, making his comedic observations amusing and informative. He needs to perform in Portland Oregon.
-
I grew up in Africa, my mother who is now 99 and still strong and sharp used to tell me about these lines but in my mother language. It is amazing to hear Neil explaining things so nicely.
-
Thank you for hiring graphic designers and animators. These videos are so much better this way.
-
I recently came back from camping with friends out at the Drakensberg mountains. I felt like an expert amongst my peers helping them identify constellations and some stars and planets. I got all that knowledge from this incredible channel.
-
Ante meridiem and post meridiem. Committing them to memory. Thank you
-
for a large part of my life AM has meant "After mid-night", and PM "Past mid-Day"
-
As a person who recently started doing Astrophotography, this is made things click. Thanks Neil and Chuck! StarTalk is the best educational channel on Youtube.
-
Loved it. I'm 66 and have learned a whole lot of new stuff! Right ascension and declination, precession, galactic equator – fascinating, thank you guys for the facts and the laughter!
-
Okay, Neil, I'm a astronomy enthusiast, but your explanation about the lines on the sky REALLY astounded me. I learned a lot, and i am very thankful ... :)
-
I love how methodical Neil's teachings are
-
Neil is so endearing, I can't help grinning watching him explain things.
-
Great Explainer. Neil Nails it everytime. He just explained the Western(Tropical) Zodiac System. Whereas, the Indian(Vedic) Zodiac system follows the actual position of the background of stars and hence it can never be incorrect. Your Vedic Zodiac Sign can never be wrong.
-
I have so memories as a kid of my Dad taking my brother and me out at night to find constellations. Such great memories!
-
The addition of editors/ clever editing, animations... its taking the channel in a direction that I really like. I can see a full on animation with animated versions of Neil and Lord Chuck immersed in an ''explainer'' universe of outer space worlds
-
I love seeing a cut away when he makes a joke. That just meant Neil was laughing so hard that it took sometime to get it back together and continue his lesson lol
-
"Them royalties dried up!" 😂 what wit and timing!
-
😮"worst than pluto for you..." 😂😂😂😂😂 As always gentlemen, thank you!
-
This is my favorite thing in the internet. Thanks for another great episode.

Fun fact: Grand Central Station in NYC has all 13 Zodiac constellations on the ceiling of the main entrance.
