What are the latest kind of telescope develop by an scientist?
By the latest ‘kind’ of telescope, I take you to mean the latest ‘design’ of telescope. The best telescopes are ones that use mirrors as the main ‘lens’ and nearly all of the big professional observatories use telescopes with mirrors. Scientists want their mirrors to be as big as possible because the larger the mirror the finer the detail they can see. Making mirrors over a certain size gets a bit tricky because the bigger they are the thicker and heavier they need to be to keep their shape. The Mount Palomar observatory for example, has a telescope with a single mirror 5 metres in diameter. This is about the practical upper limit on the size that you can go and as far as I know the last mirror of this size and type to be built. However, the latest designs of telescopes use what’s called ‘adaptive’ and multi-segmented mirror optics. The new larger telescopes get round the size problem by making the mirror much thinner, so thin in fact that you can easily bend it. To keep the mirror in
