“The Scale Of The Universe 2″ Animation Made By 14-Year-Olds Is Mind Blowing The "Scale Of The Universe 2" is an awesome Flash animation packed with info. *UPDATE: Cary Huang, creator of “Scale Of The Universe 2″, answers some questions for the Hub. See his comments below. Stars & Planets Scale Comparison A Humbling Perspective"Things are not what they seem, nor are they otherwise." This scale comparison shows "the true place" of Earth and our Sun among the various giants of the universe. It is simultaneously sobering and mind-boggling experience.First series of images opens with the Death Star compared to Mimas, one of Saturn's moons. Note the similarities between the two :)

Luna Da Wikipedia, l'enciclopedia libera. La Luna è l'unico satellite naturale della Terra. Il suo nome proprio viene talvolta utilizzato, per estensione e con l'iniziale minuscola (una luna), come sinonimo di "satellite naturale" anche per i satelliti di altri pianeti. Il suo simbolo astronomico è una rappresentazione stilizzata della sua fase crescente. La maggior parte della faccia lontana non può essere vista dalla Terra, perché la rivoluzione della Luna attorno alla Terra e la rotazione attorno al suo asse hanno lo stesso periodo, cioè la Luna è in rotazione sincrona con la Terra.

Carta topografica della Luna, con la faccia visibile a sinistra e la faccia nascosta sulla destra. La faccia nascosta della Luna è l'emisfero del satellite della Terra non osservabile dal pianeta. In realtà, per il fenomeno detto librazione, la superficie interessata non raggiunge la metà di questo corpo celeste ma è solo del 41%, pari a 15,5 milioni di km². Mai nessun essere umano poté ammirare la vista di questo lato fino al 10 ottobre 1959, quando la cosmonave sovietica Luna 3 lo fotografò per la prima volta durante il suo passaggio.

Linea di Kármán Da Wikipedia, l'enciclopedia libera. Strati dell'atmosfera[1](non in scala) L'atmosfera terrestre non termina a tale quota, che colloca nella termosfera, ma tale linea di demarcazione viene accettata per gli scopi pratici dalla Fédération Aéronautique Internationale (FAI). La FAI definisce aeronautico un volo effettuato fino alla linea di Kármán, e astronautico un volo oltre tale linea.[2] Wellcome Trust I trucchi di Gianni Golfera, l’uomo con più memoria al mondo Striscia la notizia ha recentemente dedicato due servizi a Gianni Golfera (qui e qui), un personaggio che negli ultimi anni ha avuto un certo successo negli ambienti dei corsi motivazionali grazie a una serie di dimostrazioni di memoria presentate nell’ambito di molte manifestazioni e trasmissioni televisive, anche autorevoli come Superquark. Abbiamo chiesto un parere a Federico Soldati, prestigiatore, mnemonista e mentalista, autore di un testo che sta girando in rete da qualche giorno. Chi è Gianni Golfera? Gianni Golfera si fa chiamare “L’uomo con più memoria al mondo” e afferma di aver memorizzato 261 libri a carattere filosofico, sequenze di 10 mila numeri, interi mazzi da carte, cubi di Rubik e altro ancora.

Remote sensing Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to in situ observation. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing, when a signal is first emitted from aircraft or satellites)[1][2] or passive (e.g. sunlight) when information is merely recorded.[3]

Commercialization of space History[edit] The first commercial use of satellites may have been the Telstar 1 satellite, launched in 1962, which was the first privately sponsored space launch, funded by AT&T and Bell Telephone Laboratories. Telstar 1 was capable of relaying television signals across the Atlantic Ocean, and was the first satellite to transmit live television, telephone, fax, and other data signals.[2][3] Two years later, the Hughes Aircraft Company developed the Syncom 3 satellite, a geosynchronous communications satellite, leased to the Department of Defense. Commercial possibilities of satellites were further realized when the Syncom 3, orbiting near the International Date Line, was used to telecast the 1964 Olympic Games from Tokyo to the United States.[4][5]

Space law Space law is an area of the law that encompasses national and international law governing activities in outer space. International lawyers have been unable to agree on a uniform definition of the term "outer space", although most lawyers agree that outer space generally begins at the lowest altitude above sea level at which objects can orbit the Earth, approximately 100 km (60 mi). The inception of the field of space law began with the launch of the world's first artificial satellite by the Soviet Union in October 1957. Space exploration Saturn V rocket, used for the American manned lunar landing missions The Moon as seen in a digitally processed image from data collected during a spacecraft flyby While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality.

Space colonization Space colonization (also called space settlement, or extraterrestrial colonization) is permanent human habitation that is not on Earth. Many arguments have been made for space colonization. The two most common ones are survival of human civilization and the biosphere from possible disasters (natural or man-made), and the huge resources in space for expansion of human society. However right now the challenges, both technological and economic, involved in building a space colony are as great as the potential payoff.
