![]() Near-infrared light can penetrate thick dust clouds, allowing us to learn so much more about this incredible scene.īoth views show us what is happening locally. By penetrating the dusty pillars, Webb also allows us to identify stars that have recently – or are about to – burst free. In contrast, the background light in Webb’s image appears in blue hues, which highlights the hydrogen atoms, and reveals an abundance of stars spread across the scene. These colours highlight the thickness of the dust all around the pillars, which obscures many more stars in the overall region. The background of this Hubble image is like a sunrise, beginning in yellows at the bottom, before transitioning to light green and deeper blues at the top. While the pillars of gas and dust seem darker and less penetrable in Hubble’s view, they appear more diaphanous in Webb’s. The thick, dusty brown pillars are no longer as opaque and many more red stars that are still forming come into view. James Webb will be able to use this effect to peer even deeper into space, and as such, further back in time, than any other telescope so far.The NASA/ESA Hubble Space Telescope made the Pillars of Creation famous with its first image in 1995, but revisited the scene in 2014 to reveal a sharper, wider view in visible light, shown above at left.Ī new, near-infrared-light view from the NASA/ESA/CSA James Webb Space Telescope, at right, helps us peer through more of the dust in this star-forming region. The mass of the galaxy cluster is substantially warping the fabric of spacetime with its immense gravity thus, bending and magnifying the light from other sources behind it. In addition, the redder galaxies are those that are farther away, with the wavelengths of their light stretched towards the red end by the expansion of the universe.įurthermore, a cherry on the cake is the gravitational lens effect in James Webb’s image, visible as circular smearing of light in the center of the frame. ![]() Hubble’s image on the left shows many faint stars and galaxies while James Webb’s image on the right absolutely pops with light, revealing many hidden structures. The light from this galaxy cluster took so long to reach James Webb’s eye that it essentially provides a window to look into the universe at approximately 4.5 billion years ago.Įven Hubble also took the image of SMACS 0723 and it is worth noting that the image taken by Hubble required 10 days of exposure, while James Webb’s Near-Infrared camera image took only 12.5 hours to take the image of SMACS 0723. The first image provided by NASA is a stunning view of the galaxy cluster SMACS 0723 in its most advanced version. This blog presents a brief view of the image comparison between the two telescopes James Webb and Hubble. On July 11, 2022, The James Webb Space Telescope (JWST) released its first full-color image, which NASA commented as the “deepest, sharpest infrared view of the universe to date.” James Webb is the most powerful telescope ever launched into space and is said to be a promising successor to the Hubble Telescope. ![]() “James Webb Vs Hubble” -written by Varun Bhalerao. “James Webb Vs Hubble” -written by Varun Bhalerao.
