The Hubble Space Telescope developed by NASA made significant contributions to astronomy. It presented the proof of the speeding up of the universe which is being fuelled by dark energy. This expansion rate was well measured by Hubble. It also traced the life histories of stars by watching stellar nurseries, protostellar jets, and stellar explosions that seed the universe with heavy elements needed to support life.
Hubble captured in great detail the observations of the planets in our solar system. More importantly, it established that indeed supermassive black holes existed at the heart of almost all major galaxies. Hubble showed how they have been everywhere and came to dominate the evolution of galaxies throughout cosmic history.
James Webb Space Telescope mostly works in infrared light. This makes the Webb able to observe through the cosmic dust revealing the first and most distant galaxies to have been created just after the Big Bang. It identifies smaller and younger galaxies that Hubble was unable to recognize.
Webb would analyze exactly the exoplanetary atmospheres around other stars. It has discovered certain of the molecules of those atmospheres, as vapor of water, carbon dioxide, and methane, among others. Webb also spotted possible CHEMIFACS biosignature chemicals on the exoplanet K2-18 b such as dimethyl sulfide.
Both the telescopes engage research in supermassive black holes. Webb explores the way these black holes achieved massive dimensions so early in the life of the universe. The observations together depict the role of black holes as central engines of their host galaxies in actively influencing the growth and architecture of the galaxies in the process of a feedback.
Conclusion:
Hubble determined important cosmological observation parameters such as the rate of universe expansion and the dark energy. It charted stellar evolution and chips-in on everywhere-black holes, supermassive. Webb will explore the era of the earliest galaxies and study the atmosphere of exoplanets. All combined, they give unmatched understanding into the growth of black holes and the evolution of the galaxies.
