![]() ![]() "No diversion of resources has occurred," he said. In addition, Jeletic said that both the Hubble and JWST missions are completely funded and staffed with independent budgets, so there would be no draining of Hubble resources to carry out the JWST mission. Jeletic added that Hubble is expected to continue to operate "into the late 2020s" or longer and that work is ongoing to prolong its mission, such as by preparing for future failures. "Observing the same astronomical objects with both telescopes allows for a more complete understanding of that object. "Hubble and Webb are scientifically complementary to each other," Hubble deputy project manager Jim Jeletic told Newsweek. ![]() This is because this light has been shifted into the infrared wavelengths that JWST is specifically designed to detect.īut because JWST has been designed in this way, it will miss things that Hubble can see, and vice versa. The James Webb telescope will be able to peer at objects whose light was emitted more than 13.5 billion years ago, which Hubble can't see. "Hubble's unique view of ultraviolet and visible light will be an essential scientific partner with JWST's infrared observations in order to compare galaxies at different cosmic times, deduce the composition of exoplanet atmospheres, and study the dynamics of stars and planets." Two Different Telescopes "JWST will become the primary deep space imaging telescope in infrared wavelengths of light." "Hubble will remain primary for visible and ultraviolet wavelengths of light, which JWST cannot see," said Hubble senior project scientist Jennifer Wiseman. In fact, Hubble will continue to spearhead NASA's efforts to observe distant objects in certain light spectrums. In recent months, Hubble has encountered several problems, including a computer glitch in July that caused it to shut down for days.īut NASA officials told Newsweek that JWST won't replace Hubble, nor are there plans to decommission the 30-year-old telescope any time soon. Its primary mirror has a light-collecting area that is 6.25 times bigger than that of Hubble. It will be able to peer further into space, and thus further back in time. JWST will improve on Hubble in a number of ways. NASA's Successor to Hubble Telescope Ready to Launch, Head 1 Million Miles.NASA Announces James Webb Space Telescope Launch Date. ![]()
