How far a normal telescope can let you see the universe?
Comparatively, the universe is millions of kilometres away from the planet Earth. However, we humans are delighted to see the moon and Sun with our eyes which are also millions of km away.
When we turn our face towards the sky, we see the moon and stars in dark, and sun in light, which are at tremendous distance from the earth but still can be seen. Majorly we use binoculars, a telescope or sometimes a Hubble space telescope.
Standing down on the ground, we can fix our telescope to watch beyond space, in Universe. Moreover, binoculars will not be able to offer that clarity as a telescope will offer.
Normally, a simple telescope has two lenses out of which, one collects light from the distant object and the other helps to see the output clearly. The light is seen through the telescope while looking for a distant object.
A telescope is a tool used by astronomers and researchers who dedicate their work and time to research on the universe.
Telescope is such a tool which existed since the late 16th Century. The very first telescope was developed in 1608, in the Netherlands. The spectacle makers Hans Lippershey & Zacharias Janssen and Jacob Metius independently created telescopes.
Later in the 17th century, Galileo Galilei, an Italian polymath, invented a telescope. Simultaneously, a normal telescope helps to look at galaxies and other planets in universe.
