According to Jesse Allen, an astrophysicist with NASA, “A supernova is an explosion at the end of the life of certain types of stars.” They are celestial events, when a tremendous amount of energy is released. For a few days after the explosion, the supernovas are extremely bright, and rival all the light of all the stars in a galaxy combined. They can occur in galaxies anywhere throughout the Universe. The last one seen in this galaxy was in 1604.

The Internet offers a whole new world in teaching. There are hundreds of websites geared toward learning the basics such as math, history, language arts and many others. There are also exciting and intriguing ways to learn through Webquests or virtual field trips — take your students on a Webquest to Egypt or a virtual field trip to the land of the dinosaurs. Games teach shapes, spelling and the alphabet. Money matters are learned through group or individual lesson plans. Add the Internet as one of your teaching tools, and you’ll be amazed at how excited your students will be about learning.

Our solar system is an awesome sight and contains an array of planets, moons, stars, comets, and asteroids, along with the Sun. All of the planets in the solar system revolve around the Sun, which is itself a giant star. But this is not all there is to outer space. The Sun revolves around the center of our galaxy, the Milky Way, and the Milky Way is just a small part of a larger group of galaxies. The area of space occupied by our solar system is tiny when compared to the rest of outer space and the Universe, which contains billions of other galaxies.

For thousands of years, astrologers have been studying the sun, the moon, and the stars. There have been theories about how the planets revolved around the earth or the sun, how they effected the earth’s own tides, and there have been discoveries of new planets. Here is an overview of the history of astronomy.

A chronology is an arrangement of historical events according to their dates of occurrences. Chronologies are very useful as they enable people to understand and appreciate history. In education, chronologies assist scientists and historians in their attempts to estimate the ages of certain objects, theories, or plant and animal species. They also promote understanding of various historical cultures and help scholars evaluate the relationships between events that happened in the past and those of the present and future.

Astronomy is the study of the universe. Our location in the universe is in a spiral galaxy called the Milky Way. Our solar system, housing just one star, the sun, eight planets and a few smaller entities, which are not planets, but more like moons, orbit it in elliptical, tilted orbits. Our home planet, Earth, lies 93 million miles away from the sun and has one satellite, the moon. The sun lights half of Earth at one time, giving us day. The moon lights the other half of Earth, giving us night. Humans have always looked to the sun and the moon to know what day and time it is, even what season it is.

Space exploration refers to outer space travel for the purpose of scientific research and observation. Until 1958 space exploration was considered purely a military venture, but in 1958, the United States Government launched the National Aeronautics and Space Act to regulate all activities that pertain to space exploration.

Impact cratering is the result of a collision between a meteoroid and a larger, planetary object. The planet will most likely survive the impact, but a scar, or crater, will be formed on its surface. Meteoroids impact all of the planets in the solar system, even gaseous planets like Jupiter. Because of Jupiter’s less-than-solid surface, the craters are only visible for a short time. The surfaces of Mercury and earth’s moon are covered with impact craters. Mars has seen significant impact cratering, but because of strong winds, many have eroded. The earth has impact craters, but because of its atmosphere and geological activity, a meteoroid is either burned up before the collision or the resulting crater erodes over time.

Greek mythology refers to the entire corpus of fantastic and heroic stories used by ancient Greek people to make sense of the world in which they lived. Though they are studied now mainly from a literary and cultural perspective, for the people of the classical Greek world, they were the facts of religious life. Greek mythology was intricately bound up in notions of cosmology, the study of the origin and nature of the universe.
