Hubble space telescope(HST) The Hubble Space Telescope (HST) is a powerful astronomical observatory located in low Earth orbit. The idea of a space telescope was first proposed in the 1940s, but it wasn't until the 1960s that the concept gained momentum. In 1977, NASA selected a team of scientists and engineers to develop a space telescope, and the project was named the Hubble Space Telescope in honor of Edwin Hubble, who is widely regarded as one of the greatest astronomers of the 20th century who made significant contributions to our understanding of the universe. The HST is operated by the National Aeronautics and Space Administration (NASA) in partnership with the European Space Agency (ESA).It was designed to be a general-purpose instrument, capable of observing a wide range of objects and phenomena in space, from planets and moons in our solar system to the most distant galaxies in the universe. The telescope is approximately the size of a large school bus and weighs nearly 2

  James Webb telescope  James webb space telescope (JWST) was launched on December 25, 2021.It sent it's first pictures in 2022.It is approximately 15 lakh kilometers from earth. According to NASA it takes just five seconds for data to reach earth from the telescope which is then directed to the mission centers. Some of the first images of James Webb are: Carina nebula  Carina nebula is nicknamed as the cosmic cliffs.This picture looks like “mountains” and “valleys” with beautiful stars but actually it is the edge of a young, star-forming region called NGC 3324 in the Carina nebula. Stephan's Quintet  It is a  group of five galaxies which is mostly known for being featured in a holiday film, “It’s a Wonderful Life.” Southern Ring Nebula Two cameras on james Webb captured the recent image of this nebula which is known as the Southern Ring Nebula. This nebula is almost 2,500 light-years away from earth. The detailed images that James webb have delivered are among the most breatht

First shoulderless bats were introduced in 1960's from salazenger.
