(Image credit: Studio Ella Maru) The concept of a liquid telescope mirror has been studied by astronomers for decades and is possible at a lower cost. Producing them with instruments is much more efficient than is possible today even with adaptive optical techniques. The Fluidic Telescope Experiment (FLUTE) is a program designed to investigate using liquids to construct telescope lenses.  Professor Ermanno Borra is one of the researchers who have been working on this concept for almost 20 years. With their collaborator, Omar Seddiki, they have just found a way to solve one of the main problems in realizing liquid mirrors. A medium measuring about tens of meters in diameter, will be placed on the Moon. This technique might work with liquid mirrors even if the moon's temperature is below -130 C. The construction of telescope mirrors has always faced difficulties, even in dead ends. First, because of the difficul...

  The article below discusses the top 10 largest telescopes made till date by mankind. Telescopes are optical instruments that magnify distant objects to human eye by using an arrangement of lenses or curved mirrors and lenses, or various devices. Take a look below Hubble telescope that has been in news always due to its spectacular images captured. It has recently found 6 new galaxies and has left astronomers in awe.   It was launched on April 24, 1990. It is located about 340 kilometres above the Earths surface and orbits around it 15 times per day. Before Hubble, the space exploration was a bit slow and grounded but since its initiation, the Space exploration has known no bounds.  Hubble was not the first space telescope but one of the largest ones.  What is Telescope Telescopes are optical instruments that make distant objects appear magnified by using an arrangement of lenses or curved mirrors and lenses, or various devices used to observe distant objects b...
