Just wondering if Seti@Home is putting all of it's effords to unraveling whether Oumuamua will be our 1st contact situation?

I shouldn't imagine that Seti is putting any effort at all into this. We are a scientific project, we don't react to tabloid hysteria.

We know what we are doing and why we do it.

Oh, how about a teensi weensi little reaction.
You never know, it might be aliens and Seti@Home would want to be the ones who prooved it one way or another wouldnt they? :)

What more than has already been done could seti@home do, The object isn't emitting a radio signal and we have no means to chase it with a manned or unmanned spacecraft as it exits the inner solar system since it is going way faster than is possible for a man made object at this time.

It seems that there is interest in Oumuama, in the SETI community. Both the SETI Institute and Breakthrough Listen have directed radio telescopes at the object recently. The SETI Institute used the Allen Telescope Array for this monitoring. Breakthrough Listen used the Green Bank Observatory. Please find a link, below, to an article with more information on this.

I was initially interested in the link by reading

Breakthrough Listen was using the Green Bank Telescope for a few hours last weekend. This was actually looking for water via hydroxyl lines using broadband 1.1-1.9 GHz data.

Then I looked at the site it was mentioned on

In Centauri Dreams, Paul Gilster looks at peer-reviewed research on deep space exploration, with an eye toward interstellar possibilities.

Ah not NASA then .......

Besides astronomical observations of this unique object, there is also this remote possibility: That this interloper is an interstellar survey probe, having perhaps dropped down to interplanetary-scale velocities in order to take data during its transit of our solar system, before going on to another star.


Ok, switch off time ..........

Two of NASA’s space telescopes (Hubble and Spitzer) are tracking the object


Oumuamua, may have left the solar system, depends on where our solar system ends? Scientists still need to work on that.

though its outbound path is about 20 degrees above the plane of planets that orbit the Sun. The object passed Mars’s orbit around Nov. 1 and will pass Jupiter’s orbit in May of 2018. It will travel beyond Saturn’s orbit in January 2019; as it leaves our solar system, ‘Oumuamua will head for the constellation Pegasus.


That makes it comfortably within the Solar system, even allowing for its 20 degree out of plane path.

Amen! Not to mention that we don't have surplus resources to use on stupid stuff like this.

Michael, thanks for the entertaining read.


It's interesting to note that the SETI Institute was using the Allen Telescope Array last night, as they have done repeatedly, before, to monitor Oumuamua. They combined all their observing power into one receiving beam for this purpose. They normally use three beams, each looking at different object, at the same time.

They clearly judge this to be valid scientific work. When I looked in, they were observing at around 7 GHz, over a 10 MHz bandwidth, which they can resolve into much narrower channels for analysis.

Looking for hydroxyl emission lines does not preclude the possibility of listening for and discovering an intelligent extraterrestrial signal, especially in a project dedicated to SETI, such as Breakthrough Listen.

The famous 'waterhole' around 1.4 to to 1.7 GHz has long been advocated as a band particularly appropriate for listening for SETI signals. I see that this sub-band is well within the range monitored by Breakthrough Listen.

IF it were an artificial object of some sort wouldn't it leave some sort of signature in it's wake just like a comet does when it is outgassing.

A few minutes ago, at 02:26 Universal Time, The Allen Telescope Array was again directed at Oumuamua. They're current listening around 8.440 GHz . The location of the object is little changed from last night. The Right ascension remains the same: 23.30 hours. The Declination has shifted a mite, from 6.98 degrees, last night, to 7.03 tonight. The website for observing what they're up to is:

To me, the value of studying this object as much as possible lies simply in the fact we don't often get a chance to examine something so otherworldly as close-by as this. It's a stranger zooming through our land, and there might be something interesting to learn from it.

Yes no harm in looking at it, but can we do that scientifically without everyone explicitly looking for ET.

Message 1906522 - Posted: 11 Dec 2017, 22:37:45 UTC - in response to Message 1903785.  

Russian billionaire Yuri Milner says if the space rock 'Oumuamua is giving off radio signals, his team will be able to detect them—and they may get the results within days.

The email about “a most peculiar object” in the solar system arrived in Yuri Milner’s inbox last week.

Milner, the Russian billionaire behind Breakthrough Listen, a $100 million search for intelligent extraterrestrial life, had already heard about the peculiar object. ‘Oumuamua barreled into view in October, the first interstellar object seen in our solar system.

Astronomers around the world chased after the mysterious space rock with their telescopes, collecting as much data as they could as it sped away. Their observations revealed a truly unusual object with puzzling properties. Scientists have long predicted an interstellar visitor would someday coast into our corner of the universe, but not something like this.

I think that if Oumuamua were emitting any kind of radio transmission it would have been one of the first things discovered by those who discovered it in the first place. We must face the fact that even if it were a probe made by an intelligent ET they weren't looking for us but rather just using our sun for a speed boost on the way to wherever it is going.

If it is manned or under any control, then a sling shot trajectory is likely. It could have been sent to take a quick snapshot of our system with no intention of responding to us. If later when out of earshot it signals home, they may come back later for a closer look. But apparently it is not in an elliptical orbit, it is a parabola or a hyperbola, which means it will not return naturally to where it came from*

The focus on this object from earth is from 2 camps. The ET searchers who want to believe the above, and the astronomers who just want to know more about an odd chunk of rock from outer space not seen before.

I'm with the astronomers, all seems more logical to me.

* Lets start a new conspiracy theory - It is an ET probe, and they have deliberately put it in an orbital path that won't give away where it came from. When far enough away from the Solar system, they'll realign it for home. Pass it on to all your friends :-))
