How many light years away will the James Webb telescope see?
13.6 billion light-years
With its gold mirrors, JWST should be able to see the infrared light from galaxies that has crossed 13.6 billion light-years to get to Earth. And that’s what makes the telescope a window into the past. Light from objects 13.6 billion light-years away will have taken that many years to reach the telescope’s mirror.
How much further will the James Webb telescope see than Hubble?
Webb will also go much further from Earth than Hubble. The new telescope will travel 1.6 million kilometres from our planet into a Lagrange point, where the Earth and the Sun’s gravity, along with its orbital momentum, will help keep it in one place without using up much fuel.
Where is the James Webb Space Telescope located?
The James Webb Space Telescope (JWST) is a space telescope that is part of NASA’s Next Generation Space Telescope program, developed in coordination between NASA, the European Space Agency, and the Canadian Space Agency. It is scheduled to launch in October 2018 and will be located near the Earth–Sun L2 lagrangian point.
Is the Hubble Space Telescope getting old?
But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer. NASA’s James Webb Space Telescope is in the final stages of testing, and WFIRST is waiting in the wings.
Will Webb be able to observe all the planets in space?
Yes! Webb will be able to observe the planets at or beyond the orbit of Mars, satellites, comets, asteroids, and Kuiper belt objects. Many important molecules, ices, and minerals have strong characteristic signatures at the wavelengths Webb can observe. Webb will also monitor the weather of planets and their moons.
Are there any more space telescopes in the works?
You’ll be glad to know there are even more space telescopes in the works, a set of four powerful instruments in design right now, which will be part of the next Decadal Survey, and helping to answer the most fundamental questions about the cosmos.
