Hey there !
Cosmic records of the earliest days of the universe, 13.8 billion years ago, are starting to accumulate. Soon, we may have all the clues we need to piece together the events that transformed hydrogen and cosmic energy to the blooming universe astronomers study today.
Today , scientists announced the discovery of some of the earliest traces of radiation left over from the Big Bang ever recorded. Using highly sensitive instruments, they found hydrogen atoms that had captured radiation from the formation of the universe’s very first stars. These stars formed about 180 million years after the massive event that transformed the universe from a mass of hydrogen and energy into organized galaxies.
Atoms can have different energy levels. At a baseline level, the atom’s nucleus (composed of protons and neutrons) holds onto its electrons at a particular distance. When atoms are exposed to more energy, through higher temperatures or radiation, their electrons may be pulled farther away from the nucleus. This state is called an excited state. Usually, atoms in an excited state will intermittently fluctuate back down to their ground state.
Hope it helps you !
