Accordingly big Bang The theory is that between 500 and 850 million years before the Big Bang, the universe was filled with a kind of gaseous fog that made it opaque. After 1 billion years, this haze cleared and the universe became transparent – a process called reionization.
Ryan Endsley of the University of Texas at Austin notes that all galaxies observed with Webb’s near-infrared spectrograph show signs of recent star formation. The particularly bright and distinct lines in the spectrum of light emitted by a galaxy are produced by newly formed stars that emit high-energy light that excites the surrounding gas and causes it to glow. By measuring the strength and width of these emission lines, scientists can estimate the rate of star formation, with stronger lines indicating a higher rate of star formation.
NASA has shared a high-resolution image on its website showing various galaxies, and the agency claims that more than 45,000 galaxies can be seen in the image. This means that an entire galaxy resides in every 600 pixels, showing the incomprehensible vastness and complexity of the universe.
