Space telescopes are discovering the wonders of the universe

Here’s how they do it.

Did you know that James Webb Space Telescope is the successor to the aging Hubble Space Telescope? It is currently the most advanced surveillance equipment ever created.

CScientists hope to use James Webb to observe exoplanets near our solar system and find planets that are potentially habitable. The new space telescope will also allow scientists to observe what our universe was like 250 million years after the Big Bang.

How is this done? By using massive mirrors with gold coating. In fact, most telescopes today use mirrors instead of lenses.

Using mirrors, engineers require much less glass when building space telescopes, which results in an overall reduction in the weight of the instrument, making it easier to launch into space.

But wait! We just said we launch telescopes into space? Yes! we did and we do.

How do these space telescopes work? What is the science, technology and engineering behind them? How do they compare to ground-based telescopes and what discoveries do they make? We offer you the answers to all these questions in our video.
