g Abodes - The humanity has a dream: to find extraterrestrial life. But that is hard as first of all we have to find Earth-like planets what are suitable for life and which could house living creatures. Astronomers are having a tough job in finding these planets, but lately they found a bunch of rocky planets that are positioned in the Goldilocks zone. In the constellation Monoceros astronomers found a rocky planet with a structure resembling the Earth structure, however, there are a few downsides of this planet. See article.
g Life - Remains of a dinosaur, nicknamed the 'Giraffe of the Mesozoic' due to its long neck and forelimbs, have been discovered in China for the first time. See article.
g Message - The Earth is at the center of an expanding bubble of electromagnetic radiation. The bubble, expanding at the speed of light, contains all of the man-made electromagnetic transmissions of the earth - radio, TV, radar, and so on. In theory, an alien civilization could receive these signals, and form their opinion about the earth by analyzing them. To most people, it is quite discouraging to think that some alien civilization would form their opinion of Earth based upon our situation comedies. Upon a slightly deeper analysis, the conventional wisdom says, “Aliens might detect our TV signals, but at least they can't form their opinion of our civilization from our TV transmissions. Decoding the transmission is so much harder than detecting it that we don't need to worry about this.” But an editor of the book “SETI 2020” argues that this view considerably underestimates the technologies that aliens might employ. By looking at likely technical improvements - better receivers and feeds, bigger antenna, signal processing, and perhaps stellar focusing, any civilization that can detect our radiations might well be able to decode it as well. Thus aliens can form their impression of Earth from “I Love Lucy.” See article.
g Learning - Here are video interviews of Carl Sagan (from 1995-96) by journalist Charlie Rose.
g Aftermath - Alien encounters and science fiction permeate pop culture, but what would it really mean if scientists found life beyond Earth? If even a single-celled organism on another planet was discovered, for many, this would be the last thread of evidence proving that life is simply chemistry. See article. Note: This article is from 2003.
