Some gas and dust features become a bit wispy as you start to edge into the infrared light part of the spectrum, Pontoppidan explained. “The stars themselves fade away they get fainter and fainter go to longer wavelength, but interstellar clouds go brighter and brighter and brighter.” “It will look very, very different than Hubble,” Pontoppidan said. “I think it’ll be fantastic,” Pontoppidan said, “but it’s very difficult to predict what it will look like,” as this will be the first space telescope mission of its kind. Beauty in infraredīy observing in infrared, Webb will capture uniquely beautiful images. ![]() While Hubble observes light at primarily optical and ultraviolet wavelengths, Webb is designed to detect primarily infrared light. But, while better in ways, Webb’s images will also be fundamentally “different, because it’s different wavelengths,” Pontoppidan said. “It will take amazing images they will be better than what Hubble did,” Klaus Pontoppidan, Webb project scientist at the Space Telescope Science Institute in Baltimore, said during a news conference in May. Hubble is pretty close to us in low Earth orbit, but Webb will travel out much farther, to a gravitationally stable spot 930,000 miles (1.5 million kilometers) from Earth known as the Sun-Earth Lagrange point 2 (L2).Īdditionally, while both Hubble and Webb are large space telescopes (though Webb is considerably bigger), the two actually “see” the universe very differently. But despite a handful of glitches over the years, Hubble’s science instruments are still going strong, and the two big scopes are set to observe together (albeit far apart from one another) in space. Webb is often described as Hubble’s replacement or successor. Live updates: NASA’s James Webb Space Telescope launch Not a replacement telescope One thing’s for sure: The images Webb will capture “will be detailed and spectacular,” according to the sheet. So, how will Webb’s view compare to Hubble’s? With its giant gold mirror and infrared light observation tools, Webb is designed to “see” objects 10 to 100 times fainter than what Hubble can see, according to a NASA fact sheet. What once was a faint and mysterious abyss became a detailed and colorful universe, and we could see stars and galaxies as they’d never been seen before.īut the James Webb Space Telescope, which is scheduled to launch on Dec. Over the three decades since, the famous observatory has expanded our view of the cosmos and held our attention with the stunning images it collects. The Hubble Space Telescope launched into low Earth orbit in April 1990. But how will its photos compare to Hubble’s? ![]() NASA’s James Webb Space Telescope is currently poised to launch and become the most powerful telescope in space.
