Stars 1 Measurement in Space Distances between stars and galaxies are measured in light-years. A light-year is the distance that light travels in one year. Light travels at 300,000 km/s, or about 9.5 trillion km in one year. Properties of Stars 1 The color of a star indicates its temp...
The universe, with its countless stars and galaxies, can be visually impressive, especially when we use high-powered telescopes to peer beyond the range of human vision. But what if we could hear those objects as well? That may sound impossible at first - how can sound travel through the ...
new material, including more information on galaxies and star types. Simply put, "Stars and Planets" is indispensable. Don't leave home - at night - without it. This work features: detailed charts covering all 88 constellations in the Northern and Southern hemispheres; data and notes on all ...
It notes examples of remote galaxies that are situated next to bright stars including NGC 2024 or the Flame Nebula which is near the star Altinak, NGC 3310 near the star HR 4165, and NGC 5676 which lies next to variable star CH Bo枚tis. The author also offers essentials for viewing ...

This seems necessary to explain anomalous motions of stars and galaxies.One of my best students was intrigued by the idea and began to discuss it with me. “Let me see if I understand,” he said. “Am I correct that we have known of these strange motions for about 70 years?”“Yes,...
24. Galaxies are characterized by what three shapes? Spiral, elliptical, irregular 25. True or False. The Milky Way galaxy is an elliptical galaxy. False, the Milky Way is a Spiral Galaxy 26. How does a black hole get its name? It has a black color It’s a hole in the universe Its...
