Ch. 26 The Sun and the Solar System

... History of solar System Study • Geocentric Models: Earth is the center of the Solar System. The stars were holes in a solid celestial sphere that surrounded the Earth. Beyond the sphere was a source of intense light. The belief was then that the sphere rotated with certain patterns coming around at ...

... The M Dwarf stars that will be observed are nearby, but are intrinsically faint. Most M dwarfs are V > 9 mag. They emit most of their flux in the Infra-red and tend to be ~2 magnitudes brighter in the I band. The M Dwarfs are cool, and so have a molecular absorption ‘forest’ in the infra red which c ...

... Mars' average distance from the Sun is 1.5 times greater than the Earth's average distance. As the Earth and Mars each orbit the Sun, with the Earth orbiting faster, periodically the Earth catches up to Mars and is adjacent to it. This is called an opposition, and happens every 2 years. Some opposit ...

Extraterrestrial life



Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an ""extraterrestrial"" or ""alien"" (or, to avoid confusion with the legal sense of ""alien"", a ""space alien""). These as-yet-hypothetical life forms range from simple bacteria-like organisms to beings with civilizations far more advanced than humanity. Although many scientists expect extraterrestrial life to exist, so far no unambiguous evidence for its existence exists.The science of extraterrestrial life is known as exobiology. The science of astrobiology also considers life on Earth as well, and in the broader astronomical context. Meteorites that have fallen to Earth have sometimes been examined for signs of microscopic extraterrestrial life. Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial intelligence, from radios used to detect possible extraterrestrial signals, to telescopes used to search for potentially habitable extrasolar planets. It has also played a major role in works of science fiction. Over the years, science fiction works, especially Hollywood's involvement, has increased the public's interest in the possibility of extraterrestrial life. Some encourage aggressive methods to try to get in contact with life in outer space, whereas others argue that it might be dangerous to actively call attention to Earth.
