telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. They were used for both terrestrial applications and astronomy.

I know this if off topic but I’m looking into starting my own blog and was curious what all is required to get setup? I’m assuming having a blog like yours would cost a pretty penny? I’m not very web smart so I’m not 100 certain. Any tips or advice would be greatly appreciated. Thank you
