- Meteor Terminology poster (amsmeteors.org)
In a constant effort to create excitement about Science and to increase the level of the general population’s knowledge about Meteor Astronomy, the AMS has decided to create a set of educational posters. All AMS posters are available to print for free.
- Colombia (Wikipedia)
Colombia, officially the Republic of Colombia, is a country primarily located in South America with insular regions in North America. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments. The Capital District of Bogotá is also the country’s largest city hosting the main financial and cultural hub. Other major urbes include Medellín, Cali, Barranquilla, Cartagena, Santa Marta, Cúcuta, Ibagué, Villavicencio and Bucaramanga. It covers an area of 1,141,748 square kilometers (440,831 sq mi) and has a population of around 52 million. Its rich cultural heritage—including language, religion, cuisine, and art—reflects its history as a colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by the African diaspora, as well as with those of the various Indigenous civilizations that predate colonization. Spanish is the official language, although Creole, English and 64 other languages are recognized regionally.
- Meteor shower (Wikipedia)
A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth’s atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth’s surface. Very intense or unusual meteor showers are known as meteor outbursts and meteor storms, which produce at least 1,000 meteors an hour, most notably from the Leonids. The Meteor Data Centre lists over 900 suspected meteor showers of which about 100 are well established. Several organizations point to viewing opportunities on the Internet. NASA maintains a daily map of active meteor showers.
