NASA's New Super Telescope -100 Times More Powerful Than Hubble
- 6 years ago
The James Webb Space Telescope (sometimes called JWST or Webb) will be a large infrared telescope with a 6.5-meter primary mirror. The telescope will be launched on an Ariane 5 rocket from French Guiana in October of 2018. JWST will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.
Orbiting through space nearly a million miles from Earth, the Webb telescope will open up new expanses of the near and distant universe to our view.
Webb's infrared-detecting gaze will penetrate clouds of dust within our own galaxy to reveal previously hidden secrets, and reach back in space and time to view the very edge of the cosmos.
Webb will monitor the weather and atmospheres of the giant planets and study the composition of smaller objects in our solar system.
Webb will search for signs of life-sustaining water on planets beyond our solar system, and help us learn how planets form.
Webb will see through dust-cloaked regions impenetrable to visible light, revealing the birth of stars and swirling material around black holes.
Webb will see the first, tiniest galaxies of the cosmos, and witness their evolution into vast islands of stars.
The epoch of galaxy formation is currently completely hidden from our view, and we haven’t yet observed how galaxies formed or when. We have a lot to learn about how galaxies got supermassive black holes in their centers, and we don't really know whether the black holes caused the galaxies to form or vice versa. We can't see inside dust clouds with high resolution, where stars and planets are being born nearby, but JWST will be able to do just that. We don't know how many planetary systems might be hospitable to life, but JWST could tell whether some Earth-like planets have enough water to have oceans. We don't know much about dark matter or dark energy, but we are expecting to learn more about where the dark matter is now, and we hope to learn the history of the acceleration of the universe that we attribute to dark energy. And then, there are the surprises we can't imagine!
By viewing the universe at infrared wavelengths JWST will show us things never before seen by any other telescope. It is only at infrared wavelengths that we can see the first stars and galaxies forming after the Big Bang. And it is with infrared light that we can see stars and planetary systems forming inside clouds of dust that are opaque to visible light.
The primary goals of JWST are to study galaxy, star and planet formation in the universe.
