Hours after US President Joe Biden launched the primary high-resolution picture captured by the James Webb telescope, house fanatics are evaluating the brand new telescope with its predecessor Hubble. Many customers have posted side-by-side photos captured by each the telescopes to point out the distinction between them. Whereas the pictures taken by Webb are sharper, these captured by Hubble seem to lack in particulars. The primary picture taken by the Webb telescope exhibits crystal-clear image of deep house and was offered in full color.
The pictures evaluating James Webb telescope with Hubble present how a distinct expertise utilized by the previous provides beautiful outcomes.
Right here is JWST and HUBBLE facet by facet , additionally word JWST captured this with 12 hours of publicity whereas HUBBLE took 10 days. pic.twitter.com/2Bo6W9Z229

Only for comparability, it is a facet by facet view of the Hubble’s picture and the JWST’s picture of the identical sky. It is a new period in Astronomy and we’re fortunate to be witnessing it unfold 🙂 pic.twitter.com/s8klI32MGh

American house company NASA has additionally created a web page giving an in depth comparability between the 2 telescopes.
“Webb usually will get known as the substitute for Hubble, however we favor to name it a successor. Hubble’s science pushed us to look to longer wavelengths to “transcend” what Hubble has already completed,” NASA stated on its web page.
“Webb will primarily take a look at the Universe within the infrared, whereas Hubble research it primarily at optical and ultraviolet wavelengths (although it has some infrared functionality),” it additional stated.
Webb’s main imager NIRCam operates within the close to infrared wavelength spectrum as a result of mild from the early universe has been stretched out by the point it reaches us. It permits even the faintest of galaxies to be introduced into focus.
Launched in December 2021 from French Guiana on an Ariane 5 rocket, Webb is orbiting the Solar at a distance of 1.6 million kilometres from Earth, in a area of house known as the second Lagrange level.
Right here, it stays in a set place relative to the Earth and Solar, with minimal gas required for course corrections.
A surprise of engineering, the entire venture value is estimated at $10 billion, making it one of the crucial costly scientific platforms ever constructed, similar to the Giant Hadron Collider at CERN.
