How does Jwst see back in time?
How does Jwst see back in time?
The Webb is primarily an infrared telescope, so it sees light that’s in a longer wavelength than our eyes can see. This seems nerdy and technical, but it’s actually what allows Webb to look farther back in time than the Hubble. Infrared light is often very old light, due to a phenomenon called redshifting.
Why is Jwst important?
Data from JWST will give scientists more information into the star formation process and may help address why certain numbers of stars form in certain regions, as well as how stars end up with the mass they have. Ultimately, these achievements are just the beginning.
How far out is the Webb telescope?
“The science results are going to be rolling out from here on in,” said Jane Rigby, the operations project scientist for the telescope. Two of these efforts with a high profile are devoted to exoplanets including the Trappist-1 system, just 40 light-years, or 235 trillion miles, away.
Will JWST see black holes?
The James Webb Space Telescope’s first year of observations promises to reveal exoplanet atmospheres and surfaces, infant galaxies, and maybe even the first black holes.
What is JWST looking at?
The JWST is specifically designed to pick up infrared light, which has longer wavelengths than visible light. Because light gets stretched longer and longer as it travels across the universe, much of the oldest light from the beginning of time is infrared.

How cold does Webb need to be?
All of the primary mirror segments are below the mark of 55 Kelvin (minus 360 F or minus 218 C) necessary for MIRI to operate. Further cooling “will only enhance its performance,” Gardner said.
Where is hubble telescope now?
Hubble orbits in low Earth orbit at an altitude of approximately 540 kilometers (340 mi) and an inclination of 28.5°.

The James Webb telescope will look at the Universe in the infrared, while Hubble studies it primarily at ultraviolet wavelengths, according to NASA. The combination photo showing images captured by James Webb telescope and Hubble.
What will James Webb see?
Webb, with its 6.5m-wide golden mirror and super-sensitive infrared instruments, has managed to detect in this picture the distorted shape (the red arcs) of galaxies that existed a mere 600 million years after the Big Bang (the Universe is 13.8 billion years old).
How far away is JWST now?
Located 7,600 light-years away, the Carina Nebula is a stellar nursery, where stars are born.
