In early September, NASA released a stunning image captured by the James Webb Telescope, showcasing exoplanets in four distinct spectra. This image was made possible using the NIRCAM and MIRI cameras, revealing ongoing research that continues to unveil new details about these distant worlds.
Section 1.1: Understanding the Webb's First Deep Field
The image above illustrates the galaxy cluster SMACS 0723, located billions of light-years from Earth. This remarkable view reaffirms Einstein's General Theory of Relativity, particularly through the lens of gravitational lensing. It offers insights into galaxies that previous telescopes, including Hubble, could not capture.
The light emitted by celestial objects, primarily ultraviolet, undergoes a red shift as it travels across the universe, transforming into infrared light. The advanced capabilities of NIRCAM and MIRI cameras have enabled unprecedented discoveries.
Subsection 1.1.1: The Concept of Red Shift
Red shift is observed when a star's light stretches as it moves through space, causing its wavelength to increase while frequency and energy decrease. This shift can indicate the age and distance of galaxies. The Big Bang theory suggested a maximum red shift of 14, but new findings in SMACS 0723 reveal galaxies with red shifts greater than 14, challenging previous assumptions about the universe's age.

Following these findings, the Stephen Quintet was revealed. This image, the largest ever captured, consists of numerous segments pieced together like a puzzle, illustrating a significant advancement in our understanding of the cosmos.
