Скачать или смотреть Foundations of Observational Astronomy: The Moon, the Seasons, and Mapping the Sky

This video is the first in the series of combined videos of Module 1 of my complete undergraduate course in introductory Astronomy. All the topics that you would learn in such a course are in this one video. This series tracks standard introductory textbook material that you would find at any university. There are 14 of these very-long-format videos, which follow this one in the playlist that's highlighted in the cards and links below.

Highlighted in this video are

The constellations, their history and what they are.
Angular measurement in the sky.
Coordinate systems, Equatorial (RA and Dec) and Horizontal (Alt/Az).
Naming conventions for the stars.
Elementary distances to the stars.
The reason for the seasons: solstices and equinoxes.
Lunar phases, Full/Quarter/Gibbous/crescent/new.
Lunar eclipses, and why they don’t occur every month.
Solar eclipses, and how you can watch one, and when and where they will occur.
Events like supermoons and micro-moons.
How the Moon and Earth formed.
