The Hubble Space Telescope has been a major source of space imagery for NASA for decades. However, the device will soon be replaced with its successor, the James Webb Space Telescope (JWST). According to NASA, JWST is much more than a simple replacement for Hubble.

NASA says the new device should be seen as a next-generation telescope offering many improvements over Hubble. The James Webb Telescope is the most advanced telescope ever and is scheduled to launch on Dec 18, 2021. But what can the James Webb Telescope see? Is it better than Hubble Space Telescope? Let's find out!

Is James Webb Space Telescope Better Than Hubble?

The JWST is the most powerful space telescope ever built, and it will help us learn more about our universe. It's powered by more advanced instruments and techniques. As such, it will be able to look much deeper into space than Hubble ever could.

By comparison, Webb can view the Universe in longer-wavelength infrared light while Hubble studies it primarily at optical and ultraviolet wavelengths. The longer wavelength allows it to look much closer to the beginning of time and to look inside the dust clouds where stars and planetary systems are being formed.

Webb has a much bigger mirror than Hubble, which means that it can peer farther into the past than Hubble. Also, it has a much better sensitivity than Hubble. According to NASA, this new telescope will provide better photos than Hubble, Spitzer, and other space observatories. We can now agree that the James Webb Space Telescope is better and 100 times powerful than the Hubble.

Can James Webb Space Telescope See Exoplanets?

The James Webb Space Telescope (JWST) will be the world’s premier space observatory, capable of probing the first galaxies, stars, planets, and moons formed in the universe. The telescope will also study the chemical composition of planets orbiting other stars and will search for signs of life beyond our solar system.


In any case, JWST will be able to observe the exoplanets and gain new insights into their nature. It will be able to see the atmosphere of exoplanets with high resolution and accuracy and its infrared vision will help us determine the composition of these atmospheres. Webb telescope has an advanced technology that will help it see through clouds and other atmospheric interference, which can confuse our observations of planets. The James Webb Space Telescope will be a powerful tool for studying the atmosphere of a habitable-zone planet.
