Possessing a larger mirror, wavelength coverage, and light-collecting area, this telescope will be able to explore new terrains and transmit crystal clear images for the world to enjoy. The James Webb Telescope was launched 30 years after the Hubble, so it stands to reason that the technology of this device would be superior. How Much Better Is The James Webb Telescope Over The Hubble? The observations from this space observatory could help us to learn more about the formation of our Universe and explore previously unseen alien worlds. The JWST possesses a light-collecting area of around 25 meters (almost six times greater than the Hubble).Īt the cost of $10 billion, this is NASA’s biggest, most powerful, and most ambitious telescope to date. Its primary mirror boasts a diameter of 6.5 meters and consists of 18 hexagonal mirror segments carefully crafted from gold-plated beryllium. In addition, this powerful telescope can look inside dust clouds and observe the new planetary systems that are just beginning to form. This means that scientists will be able to search nearer to the beginning of time and view previously unseen remnants left behind during the formation of some of the first galaxies. The upgraded design includes improved sensitivity and broader wavelength coverage. This gravitationally stable space location has been popular with a number of other space telescopes like the Herschel Space Telescope and Planck Space Observatory. First deployed on 25th December 2021, this telescope aims to complement the Hubble and extend the longevity of our astronomical discoveries.Īfter a 30-day mission that saw the JWST travel 1.5 million kilometers, it finally arrived at L2. The James Webb Space Telescope (JWST) is an infrared observatory that orbits the Earth. It is predicted to last until somewhere between 20. The Hubble telescope can detect light from ultraviolet to almost infrared, allowing it to capture some breathtaking images of space that have delighted space enthusiasts worldwide. This remains to be the only telescope designed for compatibility with astronaut maintenance. Thanks to five servicing missions, the capacity of the Hubble telescope has grown immensely over the past three decades now, cutting-edge instruments provide us with an even deeper insight into the Universe. It also has various recording instruments that include a wide field planetary camera. The primary mirror is 2.4 meters, while the secondary one is slightly smaller. The Hubble Space Telescope (or HST) is a reflecting telescope that uses mirror optics to gather light from celestial objects, then direct it back to two cameras and two spectrographs. During its lifetime, the Hubble telescope has made more than 1.5 million observations, and more than 19,000 scientific papers have been published from its discoveries. Located high above light pollution, clouds, and atmospheric distortions, the Hubble has a crystal clear view of the night sky, allowing astronomers to see stars and galaxies that are light years away. While it was not the first telescope that we launched into space, it remains one of the largest and most versatile pieces of equipment that is still integral to the field of astronomy today. Named after the trailblazing US astronomer Edwin Hubble, the Hubble telescope is a sizable space observatory that revolutionized astronomy from the moment it launched on 24th April 1990. ![]() ![]()
