What s A Liquid Mirror Telescope
Ernesto Capocci, an Italian astronomer, was the first individual to describe how an LMT would possibly work in 1850. He conceived of the concept after reading about experiments, carried out by Isaac Newton and others, involving spinning liquids. In the early 20th century, the American physicist R.W. Wood truly built what Capocci had described 50 years earlier. Wood's LMT featured a one-centimeter layer of mercury placed in a rotating dish. He was able to observe the moon but famous that the picture was distorted.

At the moment the Parker Solar Probe, which launched in 2018 to check the solar, is the quickest-ever human-made object, including spacecraft. In response to NASA, thus far, it has reached speeds of 244,255 miles per hour (393,044 kilometers per hour) and it expected to achieve a high pace of about 430,000 miles per hour in 2024.
