Spherex is a space telescopespace telescope eagerly awaited by the community astronomerastronomer who hopes to obtain the most precise and colorful three-dimensional cosmic map possible. To do this, Spherex will observe in more than nine million different directions.
The expansion of the Universe
Spherex’s main work lies in spectroscopy, that is to say the decomposition of light into different colors – or wavelengths – in order to obtain maximum information.
Spherex you Jet Propulsion Laboratory (JPL) will observe in the infrared domain, to examine galaxiesgalaxies appeared the day after Big BangBig Bang until today. For this, its instrumentation will deal with the precision of Hubble or télescope spatial James-Webbtélescope spatial James-Webband with the wide-field view of the old Wise space telescope of the NasaNasa.

Unrivaled precision
The precision of Spherex will offer astronomers the means to calculate with unparalleled precision the redshift of a starstar or a galaxy, namely the red shiftred shift of its light, which indicates how far the star or galaxy is moving away from us (this is comparable to theDoppler effectDoppler effect which can be observed with a sound source in movementmovementlike an ambulance that approaches, then moves away from us).
These indications will allow astronomers to locate galaxies and determine their movement throughout the history of theUniverseUniverse. In fact, we will be able to know more about the expansion of the Universe.
In search of cosmic water
Another objective of Spherex is to be able to measure the quantity of iced water, carbon dioxidecarbon dioxide and other ingredients necessary for life. Planetary scientists hope to learn more about the availability of these moleculesmolecules.
