Tonight We are looking for life on another planet Aug. 29

Recommended Posts

A powerful signal has been spotted coming from the vicinity of a sunlike star, and now astronomers are trying to figure out what it means.


In May 2015, researchers using a radio telescope in Russia detected a candidate SETI (search for extraterrestrial intelligence) signal that seems to originate from HD 164595, a star system that lies about 94 light-years from Earth, the website Centauri Dreams reported over the weekend.


The astronomers have not yet published a study about the detection; they plan to discuss it next month at the 67th International Astronautical Congress (IAC) in Guadalajara, Mexico, according to Centauri Dreams' Paul Gilster, who wrote that one of the team members forwarded him the IAC presentation.

HD 164595 is known to harbor one planet — a roughly Neptune-mass world that orbits too close to the star to support life as we know it. However, it's possible that other worlds lurk undiscovered in the system, said astronomer Seth Shostak of the SETI Institute in Mountain View, California, who is not part of the detection team.


The scientists who made the detection are respected researchers, and the signal is strong enough that it's probably not just random noise, Shostak told Space.com. Furthermore, the signal is consistent with something an alien civilization might send out — and if aliens did indeed do it, they are certainly far more advanced than we are, he added.


Based on the received signal's characteristics, aliens would have to generate about 100 billion billion watts of energy to blast it out in all directions. And they'd still have to produce more than 1 trillion watts if they beamed it only to Earth for some reason, Shostak said.


"The first number is hundreds of times more than all the sunlight falling on Earth," he said. "That's a very big energy bill."

I wouldn't get my hopes up. My guess is that that Russians had a government budget-decision coming up, and needed to hoak something up to justify their existence. Have a look at this appraisal: https://setiathome.berkeley.edu/forum_thread.php?id=80193

Yep, doesn't sound promising at all. My thought all along is maybe we are looking for something that an alien form would not consider as sound or sending material if they were even looking.
