![]() Astronomers are eager to close the 300 million year gap with Webb and draw ever closer in time to the Big Bang, the moment the universe formed 13.8 billion years ago. Hubble has stared as far back as 13.4 billion years, disclosing a clumpy runt of a galaxy that is currently the oldest and farthest object ever observed. This light will reveal how the original stars looked 13.7 billion years ago. Webb is expected to behold light from the universe’s first stars and galaxies, beyond Hubble’s range. NASA Releases Stunning New Pic of Milky Way's ‘Downtown' Let There Be Light Bigger and more intricate than Hubble, Webb will be a goner if its foldout mirror and sunshield snarl.

It quickly ran into trouble: one of the telescope’s solar wings jammed as it was unfurling. Hubble caught a lift to orbit tucked inside NASA’s space shuttle Discovery in 1990. The lowdown on Hubble versus Webb: Rocket Rides Its liftoff is slated for Saturday morning from the coast of South America. With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different. ![]() Sign up for NBC Philadelphia newsletters.
