A correct, or at least close, Hubble parameter would lead astronomers and cosmologists to not only determining the distances to these galaxies, but the age of the observable Universe itself.

The root word meteor is derived from the Greek word meteōros , which means high in the air . Most meteor showers are comet dust particles left behind as a comet orbits the Sun.

Some of the early notions pictured the stars on glass spheres which turned around Earth; stars beyond the Sun were not pictured to be that far away. The term space is very appropriate when talking about the distances between the stars, between galaxies, and yes, even between the planets in our own Solar System. (1)

When an object is observed closely for a long time, the light stimulating the retina eventually causes the cones in that area to become fatigued, desensitizing that part of the retina. The affected portion of the retina continues to produce the image for up to 30 seconds, but because the stimulation comes only from the less-fatigued cones, it is perceived as a negative image.

In this lab, you will explore how spectroscopy works and learn in introduction to astronomy about star color versus star temperature. The lab exercise will take the concept outdoors, where you will visually observe and catalog different stars with varying colors. (1)

This geocentric Solar System model was accepted by both scientific and religious circles until the work of Nicolas Copernicus (1543) and observations with the telescope of Galileo Galilei (1609) showed the Sun was the center of the Solar System, a heliocentric model.

In order to better understand modern optics such as binoculars, cameras, and telescopes, and how lenses and mirrors work, you will conduct specified experiments with lenses and mirrors in this lab. With the supplied lab kit resource, you will assemble a simple refracting telescope. You will take the telescope outdoors and conduct a series of observations with the simple telescope. (1)

A number of the clubs do special activities, such as how to buy a telescope and how to use a telescope. And, a few still offer classes on making a telescope; the Eastbay Astronomical Society in the San Francisco Bay area is well-known for the telescopes attendees make in their Telescope Makers Workshop.
