Earth Analog (A) An Earthlike planet with a rocky moon elsewhere in the Milky Way is inhabited by a technologically advanced civilization. This civilization has positioned an array of telescopes on the dark side of the moon to detect signs of other life in the universe. The "0s and 1s" represent the binary code used by computers. Humans on Earth use a large amount of computing time and power to process data from space for signs of intelligent life. There is a possibility that an alien civilization may communicate in a binary code as well, sending such messages toward Earth. | |

| Smokers At the bottom of an alien ocean smokers similar to those on Earth can be found. Life forms are abundant here. Despite the heat and pressure they have learned to adapt and survive. |

| Alien Ocean |

Curious rock formations dominate this calm ocean. If it weren't for the two suns in the sky and the unusual moon, one might think this were an exotic tropical beach on Earth. |

Cosmic Awakening
This radio telescope dish is a huge hibiscus flower, with the pistil pointing up toward the sky. Far off in space is a star which represents another planet inhabited by an intelligent life form. This image is available as a framed miniature. |

Cosmic Awakening Detail The extraterrestrial civilization, represented by the small purple flower, has developed radio technology and sends a radio signal out into space. The signal travels toward Earth and will be received by the large radio telescope here. |

Panspermia
It is theorized that living bacteria on rocks ejected from their planet of origin into space might survive the journey long enough to seed another world. While this is unlikely to occur over large distances, such as from one solar system to another, it may happen between planets within the same solar system. This image conceptualizes this idea, showing bacterial colonies on an asteroid falling toward Earth.

| Optical SETI |
Some new SETI searches are now looking for alien messages at optical frequencies rather than radio wavelengths. These could be in the form of pulsed laser beams.
