![]() The pillars are a small region within the Eagle Nebula, a vast star-forming region 6,500 light-years from Earth. It acts like thick smoke or fog, preventing us from peering into the deeper universe, where countless galaxies exist. In the infrared image, we can see more stars that weren't visible before. Dust blocks the view in Hubble’s image, but the interstellar medium plays a major role in Webb’s. Webb vs Hubble Telescope Visible vs Infrared Comparison of the Carina Nebula in visible light (left) and infrared (right), both images by Hubble. Although Hubble highlights many more thick layers of dust and Webb shows more of the stars, neither shows us the deeper universe. 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. Let’s start with the most obvious difference between the two, which is in size. ![]() 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. Hubbles mirror is a much smaller 2.4 meters in diameter and its corresponding collecting area is 4.5 m2, giving Webb around 6.25 times (see calculation) more. The most complex, nail–biting sequence was unfolding a giant sun shield designed to block radiation from the sun, moon and Earth that would overwhelm the telescope's super sensitive instruments.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. In fact, the launch was so precise, the telescope will have extra manoeuvring fuel leftover to operate beyond its expected 10–year lifetime. Since it was launched on Christmas Day 2021, that sequence of events has so far proceeded as planned. Once in space, the unfolding sequence involved 50 major deployments with 344 of what the scientists call "single-point failure" items involving latches, hinges, motors, bearings, gears, cables and pulleys. This giant, super-sensitive instrument had to be made as lightweight as possible, yet strong enough to withstand the vibrations and G-forces of a rocket launch. There is no room for mistakes and no possibility of repair by astronauts if something goes wrong. ![]() Though it's natural to compare the abilities of, the Hubble space telescope, the James Webb Space Telescope, and the. r/space James Webb Telescope captures the same galaxy at three different points in time in a single mind-boggling image. By comparison, Hubbles mirror is 2.4 meters (7.8 feet) in diameter, with a collecting area of a little more than 4.5 square meters (nearly 50 square feet). Hubble, with its 2.4 metre aperture, can see objects at least 60,000 times fainter than the human eye (which is then greatly extended by using cameras to take long exposure photographs). Space telescope showdown: Nancy Grace Roman vs the James Webb vs Hubble. The two missions overlap and can work together on new discoveries. This also happens with earth based telescopes that use the same kind of Newtonian reflector design. The James Webb Space Telescope is Hubbles successor, but not its replacement. This picture from a NASA TV broadcast shows the James Webb Space Telescope shortly after separating from the Ariane 5 rocket after launching from French Guiana, on December 25, 2021. Hubble has 4 arms that produce 1 spike, so you get the classic 4 prong shape.
