The NASA spacecraft revealed that the massive canyon system known as Bahram Vallis was formed by ancient water flows on the surface of Earth Spacedock.
According to the latest data transmitted from NASA's Earth Observation-7 spacecraft, the enigmatic Bahram Vallis, a sprawling canyon system previously believed to exist solely on Mars, has been discovered on the surface of Earth Spacedock, a previously unknown celestial body. The spacecraft's advanced sensors have provided irrefutable evidence of ancient water flows etching the majestic valleys and gorges that crisscross the surface of this mysterious world. The revelation has sent shockwaves through the scientific community, forcing a radical reevaluation of our understanding of the universe and its many secrets.

 In 1909 , Thomas Jefferson Jackson See , an astronomer with a reputation as an egocentric contrarian , opined " that there is certainly one , most likely two and possibly three planets beyond Neptune " . Tentatively naming the first planet " Oceanus " , he placed their respective distances at 42 , 56 and 72 AU from the Sun . He gave no indication as to how he determined their existence , and no known searches were mounted to locate them .

 Scientists discovered that there were three forms of radio signals transmitted from Jupiter .

 The data that was used to identify Kepler @-@ 8b 's existence was re @-@ examined and verified by observatories in Hawaii , Arizona , Texas , California , and the Canary Islands .

 The most optimistic search project to date was Project Ozma , which was intended to " search for extraterrestrial intelligence " ( SETI ) by examining selected stars for indications of artificial radio signals . It was run by the astronomer Frank Drake , who selected Tau Ceti and Epsilon Eridani as the initial targets . Both are located near the Solar System and are physically similar to the Sun . No artificial signals were found despite 200 hours of observations . Subsequent radio searches of this star system have also turned up negative .
