What is NIRSpec?
The NIRSpec enables scientists to obtain simultaneous spectra of more than 100 objects in a 9-square-arcminute field of view. It provides medium-resolution spectroscopy over a wavelength range of 1 to 5 micrometers and lower-resolution spectroscopy from 0.6 to 5 micrometers.
How long will James Webb last?
Webb’s mission lifetime after launch is designed to be at least 5-1/2 years, and could last longer than 10 years. The lifetime is limited by the amount of fuel used for maintaining the orbit, and by the possibility that Webb’s components will degrade over time in the harsh environment of space.
Is James Webb much better than Hubble?
Webb will have significantly larger field of view than the NICMOS camera on Hubble (covering more than ~15 times the area) and significantly better spatial resolution than is available with the infrared Spitzer Space Telescope.
What is the most powerful telescope?
James Webb Space Telescope
October 15, 2021 12:20 am NASA. Some have called NASA’s James Webb Space Telescope the “telescope that ate astronomy.” It is the most powerful space telescope ever built and a complex piece of mechanical origami that has pushed the limits of human engineering.
How does a spectrograph work?
How Does a Spectrograph Work? A spectrograph passes light coming into the telescope through a tiny hole or slit in a metal plate to isolate light from a single area or object. This light is bounced off a special grating, which splits the light into its different wavelengths (just like a prism makes rainbows).
How far back in time can Hubble see?
about 10-15 billion light-years
The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
How big is the universe?
about 93 billion light-years
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

Who owns the biggest telescope in the world?
The largest visible-light telescope currently in operation is at Gran Canarias Observatory, and features a 10.4-meter (34-foot) primary mirror. The Hobby-Eberly Telescope at McDonald Observatory near Fort Davis, Texas, has the world’s largest telescope mirror.

What’s the best telescope on Earth?
James Webb Space Telescope, the world’s largest and most powerful space telescope, will be launched in 2021. The world’s largest and most powerful space telescope unfolded its giant golden mirror for the last time on Earth on Tuesday, a key milestone before the $10 billion (roughly Rs.
What is spectrograph used for?
A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate. Many astronomical observations use telescopes as, essentially, spectrographs.
How big is the field of view of NIRSpec?
The NIRSpec enables scientists to obtain simultaneous spectra of more than 100 objects in a 9-square-arcminute field of view. It provides medium-resolution spectroscopy over a wavelength range of 1 to 5 micrometers and lower-resolution spectroscopy from 0.6 to 5 micrometers.
What kind of detectors are on the NIRSpec?
The NIRSpec employs a micro-electromechanical system “microshutter array” for aperture control, and it has two HgCdTe detector arrays. Space Telescope Science Institute has technical page on NIRSpec.
What is the wavelength range of a NIRSpec?
NIRSpec will operate over a wavelength range of 0.6 to 5 microns. The Near InfraRed Spectrograph (NIRSpec) will operate over a wavelength range of 0.6 to 5 microns. A spectrograph (also sometimes called a spectrometer) is used to disperse light from an object into a spectrum.
How does a NIRSpec microshutter work in the sky?
NIRSpec’s microshutter cells, each approximately as wide as a human hair, have lids that open and close when a magnetic field is applied. Each cell can be controlled individually, allowing it to be opened or closed to view or block a portion of the sky.
