This is the "How Far Away Is It" video book channel. It is a video book of Hubble and other Space and ground based Telescope pictures together with an illustrated explanation of how we know how far away these objects are - from your back yard to the most distant galaxies. See how: Triangulation can take us across the globe Parallax can take us across the solar system Standard candles can take us across the Milky Way Red-shift can take us across the universe. The video book contains three chapters: The Solar System; The Milky Way; and Galaxies. A Distance Ladder foundation is built in segments 2 (The Earth) through 6 (Distant Stars). The amazing celestial object photography begins with segment 7 ( Planetary Nebula). Many viewers may want to start there. Students, new to Astronomy, should start from the beginning. There is also a preface and a segment on credits with websites identified that can be used for further research by interested viewers.

We’ll start with our last look at DART in our solar system. We’ll cover new information on famous Milky Way celestial objects like the Horsehead, Little Dumbbell, and the Crab nebulae. Moving out to galaxies orbiting ours, we’ll cover a super nova and brown dwarfs. Further out into our Local group, we’ll take a closer look at Triangulum. We’ll cover new information on galaxies tens of millions of light years away including the Cigar, Sombrero, Penguin, and others. We’ll also see a protocluster, supernova, and black hole merger billions of lightyears away. And we’ll see two galaxies that formed near the end of the Dark Ages; Firefly Sparkel. We’ll end with coverage of Webb's first 2024 release. It showcases near- and mid-infrared portraits of 19 face-on spiral galaxies in the Virgo Supercluster. Music: -
