WHAT IS A TELESCOPE AND WHO INVENTED IT:
A telescope is a device used to see further items up close. The creators of the telescope are none other than Hans Lippershey, Zacharias Janssen, and Jacob James Metuis.
A telescope is an optical device composed of two or more (usually convex) lenses, such that when viewing a distant object, the image created by the first – the objective lens, is then magnified by the second – the eyepiece. This has the effect of making distant objects appear larger or nearer to the viewer, allowing more object detail to be seen. The invention of the telescope as a scientific instrument is often accredited to Galileo Galilei. This is probably incorrect. Hans Lippershey, a Dutch lensmaker is usually acknowledged for the earliest recorded design for an optical telescope in 1608, but he may not have actually invented it. Thomas Harriot, an English astronomer was certainly using one the following year in July 1609 when he was drawing the Moon. Galileo didn’t use a telescope until four months later.
