The Teen Titans are a fictional superhero team appearing in American comic books published by DC Comics, often in an eponymous monthly series. As the group’s name suggests, the members are teenage superheroes, many of whom have acted as sidekicks to DC’s premier superheroes in the Justice League. The original team later becomes known as the Titans when the members age out of their teenage years, while the Teen Titans name is continued by subsequent generations of young heroes. First appearing in 1964 in The Brave and the Bold #54, the team was formed by Kid Flash (Wally West), Robin (Dick Grayson), and Aqualad (Garth) before adopting the name Teen Titans in issue 60 with the addition of Wonder Girl (Donna Troy) to their ranks.
The existence of ample amounts of hydrogen in the subsurface ocean of Enceladus indicates that microbes--if any exist there--could use it to obtain energy by mixing with carbon dioxide dissolved in water. This particular chemical reaction, termed methanogenesis, because it manufactures methane as a byproduct, may have been of critical importance in the emergence of life on our planet.
In the Eastern world, such as in China and India, the moon is actually the primary consideration in studies of astrology. The moon signs and cycles are used to determine the best time for activities, and is a part of daily life. This may seem backward to some, but actually results in more accurate predictions in many cases than Western astrology can ascertain.
Until 2004, no spacecraft had visited Saturn for more than twenty years. Pioneer 11 took the very first close-up images of Saturn when it flew past in 1979. After that flyby, Voyager 1 had its rendezvous about a year later, and in August 1981 Voyager 2 had its brief, but glorious, encounter. Nearly a quarter of a century then passed before new high-resolution images of this beautiful, ringed planet were beamed back to Earth.
