Earth size and in the outer edge of the Goldilocks zone
2017 NASA plans to launch Transiting Exoplanet Survey Satellite (son of Kepler)
MIT’s Murchison Widefield Array, located in the Western Australia Outback, is another new tool in the search for intelligent life in space
The telescope features 512 tiles, each containing 16 antennae, for a total of 8,192 antennae!
Computer integration allows the separate antennae to function as if they were one single huge antenna dish = 8,192 m2
Trained on the 21 cm band of Hydrogen/Hydroxyl ion (H/OH), the so-called galactic “watering hole”
Basic idea is that water is so essential to life that all alien races, knowing that to be true, would most likely broadcast their signals in that range, where another race would most likely be listening – big assumption!
Though designed to study the role of hydrogen in the early evolution of the universe, the focus on the 21 cm Hydrogen band means the data can also be used to look for SETI signals
Deep space photographs show immense galactic clusters
There may be as many as 100 billion galaxies in the universe
Each galaxy may hold 100 billion stars
Surely, in all that magnificent immensity, there must be other worlds and other races
Brush up on your klingon verbs, just in case…
Where is everybody?
SETI and other cosmic search projects have been listening in vain for several years for signals from the stars
