Why do scientists study the early epochs of cosmic history?
Astronomers call this the “dark age” of the universe, since no stars had formed yet. Researchers are using the best observatories in the world both to study the dark age and to find evidence for the first stars in the universe.
May 31, 2018 · Webb is engineered to observe the earliest stages of galaxy formation and astronomers are hopeful it will allow them to study the formation of the very first galaxies. Webb could show how small galaxies in the early universe merged to form larger galaxies.
Webb is able to see back to about 100 million - 250 million years after the Big Bang. But why do we need to see infrared light to understand the early universe? Because light from these objects is shifted to the red.
Science. The Beginning of Everything. The big bang—we’ve given a name to the beginning of time and space, but really it represents a lot of unanswered questions: how did the first stars and galaxies form, and how did the building blocks of everything—including humans—come to be?
Jun 23, 2021 · They will study the properties of these quasars and their host galaxies, and how they are interconnected during the first stages of galaxy evolution in the very early universe. The team will also use the quasars to examine the gas in the space between galaxies, particularly during the period of cosmic reionization , which ended when the ...
Jun 24, 2020 · Mapping the Early Universe with NASA’s Webb Telescope. NASA Webb Telescope Team. Jun 24, 2020. Article. Astronomers and engineers have designed telescopes, in part, to be “time travelers.” The farther away an object is, the longer its light takes to reach Earth.
