SETI Undergoes Drastic Reduction. We’re Looking But No Longer Listening

Allen array used by SETI

By now astronomers and space enthusiasts alike are bemoaning the recent crushing news that SETI has been forced to put the Allen Telescope Array into “hibernation” due to a drastic reduction in outside funding. And while there are other radio telescopes throughout the Earth, the Allen Telescope Array is one of the most essential. Just how bad is this news for those who hope to shake hands (tentacles?) with an extraterrestrial life? To quote from Ellie’s internal monologue in Carl Sagan’s Contact “…she was surprised that, in the search for extraterrestrial intelligence, what could be done was so far ahead of what had been done.”

Contrary to the pop culture image some might have of SETI; radio telescopes are not used exclusively for the search for extraterrestrial signals. Further, SETI does not have one specific home, or array, from which it operates. Like any other scientific or commercial entity, SETI has to book time on radio telescopes for their activities. The Allen Telescope Array was key to SETI’s endeavors, as the Array was created primarily with the intent of furthering SETI’s activities.

While the likelihood of actually receiving a long distance communication from space is exceedingly low, those odds drop to zero if we’re just not listening.

There is a particularly galling irony present when one considers the exoplanet data pouring in from the recently launched Kepler telescope. SETI Director Jill Tarter says it best, “There is a huge irony that a time when we discover so many planets to look at, we don’t have the operating funds to listen.”

This should be extremely frustrating not only for people interested in outer space, but really anyone who has any reverence for science that has taken a chance.

In another scene from the novel version of Contact, Valerian instills in Ellie exactly why SETI is so imperative:

“Nobody’s guaranteeing success. But can you imagine a more important question? Imagine them out there sending us signals, and nobody on Earth is listening. That would be a joke, a travesty. Wouldn’t you be ashamed of your civilization if we were able to listen and didn’t have the gumption to do it?”

The SETI Institute needs roughly 5 million to continue using the Allen Array. You can find more information and donate to SETI through their website.

Though I'm a huge SF fan and I sort of hope that we do eventually make contact, I'm finding it hard to mourn this too much. SETI cost a ton of money, was founded on all sorts of problematic assumptions, and had an astronomically low chance of success. The only reason it was ever justifiable was if you assumed that the benefits of finding an ETI were close to infinite, which is almost certainly false. I'm not shedding any tears for it.

"several members of the Hat Creek observatory staff having already been laid off"

I'd read about this, but I hadn't realized that the Allen Array was at Hat Creek. Ive been there--Hat Creek is one of the best hang gliding sites in California and possibly in the world. In the evenings, it gets "glass-off" when all the air heads upwards and flying is as easy as sculling a boat on a lake.

To get to the Hat Creek launch, you drive past the turnoff to the radio observatory... And now thanks to the State of California's budget cuts to higher education, Cal has started flensing actual science. It's not just SETI that will suffer. There were radio telescopes investigating the universe there long before the Allen Array.

And what about the town of Burney? It was nice to have an ambulance handy, for the flying. Damn.

SETI costs next to nothing. As does the search for near-Earth asteroids. People who see no benefit in such meagre expenditures in pursuit of extraordinary knowledge are hopeless philistines and undeserving of the legacy of thousands of years of human curiosity. They are little men who do not deserve to stand on the shoulders of giants.

The Hat Creek budget would be paid for with 24 hours worth of flying time for a single jet currently dropping bombs on any of a number of countries.

In Contact, the project is funded by an eccentric billionaire. Shame there aren't more of those around, to whom $5 million would be spare change.

@Nomad UK- that's what we're saying! Thank you!
