LINERs have been at the center of two major debates. First, astronomers have debated the source of energy that excites the ionized gas in the centers of these galaxies. Some astronomers have proposed that active galactic nuclei (AGN) with supermassive ...
Starting with the Earth’s formation by accretion from the solar nebula 4.54 billion years ago (4.54 Ga), the first eon in the Earth’s history is called the Hadean. It lasted until the Archaean eon, which began 3.8 Ga. The oldest ...
