Lesson 16.3
... You can see Ursa Major all year. But other constellations can only be seen at certain times of the year. Canis Major is a constellation we see only in the winter. The constellations change with the seasons. This is because Earth rotates, or spins. It takes Earth one year to move around the Sun. We s ...

... The Hubble formula provides a very powerful way of determining not only distances of remote galaxies but also the age of the Universe itself. He stated that they were related by the formula: Velocity of recession (v) = Hubble constant (H) x distance (r) where H is Hubble's constant and r is the dist ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
