A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. These are typically formed from extinct volcanoes, that rise
abruptly and are usually found rising from a seafloor of 1,000 - 4,000 meters depth. They are defined by oceanographers as independent features that rise to at least 1,000 meters above the seafloor. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea.[1] An estimated 30,000 seamounts occur across the globe, with only a few having been studied. However, some seamounts are also unusual.

The scientific attempt to detect intelligent extraterrestrial life by surveying the sky to find the existence of transmissions, especially radio waves or light, from a civilization on a distant planet
. The SETI Institute, that carries out the project, is a private non-profit center founded in 1984. There are many methods that SETI scientific teams use to search for extraterrestrial intelligence. Many of these search billions of radio frequencies that reach Earth from all over the Universe, looking for an intelligent radio signal. Other SETI teams search by looking for signals in pulses of light emanating from the stars.
