Astronomers have detected nearly 2,000 alien planets to date. As that number continues to rise, so too does the prospect of finding intelligent extraterrestrial life.
In terms of the search for extraterrestrial intelligence (SETI), it may no longer be a matter of answering the "are we alone" question, some scientists say. Rather, just how crowded is the universe?
And if ET is out there, it may be possible to reach out with direct "radio waving" to potentially habitable exoplanets. This form of cosmic cryptography, called "Active SETI," involves no longer merely listening for a signal but purposefully broadcasting to, and perhaps establishing contact with, other starfolk.
Active SETI sounds like science fiction, but some astronomers are discussing it seriously today. The idea is, as it has been in the past, a controversial, hot-button issue, with some researchers wary of sending signals out to touch base with intelligent aliens.
Work in progress
"It’s a subject of discussion, I’ll put it that way," said Seth Shostak, senior astronomer at the SETI Institute in Mountain View, Calif. There have been many workshops and symposia over the years to discuss Active SETI, he said, and because it has a highly emotional component, "it’s like a third rail in a way," he said.
Shostak told Space.com that he feels the topic is not something to worry too much about.
"But there may not be that perception in the broader public … that we have discussed this to death. They haven’t seen these discussions nor participated in them," he said.
But exoplanet detections are making news around the world, Shostak said. "That’s putting the whole question of life in space in front of the public in a way that perhaps wasn’t true 20 years ago." . . .
