Just curious - read through the Nebula, most well over my head, but got me to wondering...
Though considering how long SETI ran, someone must have thought this (or it is totally wrong and irrelevant?):

Has anyone talked the radio telescope people into pointing their dish(s) at the furthest solid planet in our solar system that should reflect Earth's signals, and see what kind of data is returned by reflection off of it?
This would provide a sample of very strong signals to analyze and write algorithms to properly find real signals in.
This stuff is so far over my head - so if my question is meaningless - don't bother replying... but if it might have helped, something to think about.
Someone probably thought of this on the first day... LOL

Been with SETI since July 2000 - it has been fun, optimistic, and interesting...
Thanks and I will be ready if something comes up - like a Nebula analyzing BOINC app... ?

That's a very good thought and a good question...

As it happens, I believe that s@h has indeed detected signals from our various space probes that are drifting across our solar system.

We also have a multitude of signals detected that are inadvertent radar/radio reflections off aircraft flying around various parts of the world! A large part of the Nebula work is to develop new algorithms that can reliably distinguish between the many signals that have been found that originate from Earth, vs another multitude of signals that are random noise, vs anything else found that is not Earthly and not noise.

The filtering out of all the known stuff to then leave only what is truly unknown is the really hard bit! Hence the very real research work developing Nebula...

Hey! Good going.

Yes, this is still a world leading interesting project. One that has evolved from the early days of whether something such as Boinc was even possible, to now deeply investigating the signal riches that we have found.

There is a lot more to come yet.

There are just the minor details of researcher time, research grants/funding, and developing Nebula or a parallel successor to guide how we search further and farther!!

Keep an eye on the forums for "what next"!

Hi Todd,

With limited resources Radio Amateurs are doing something in that way since the Seventies. They are using the moon as a reflector to bounce fast telegraphic signals back to earth, the so called Moon Bounce. Also ionised atmosphere by meteor showers are successfully used, Meteor Scatter. Mars and Venus have been used to reflect signals back to earth in order to test communication equipment for amateur radio satellites.
As an initiation test, using simple reception equipment, you can hear signature signals of objects entering the atmosphere by tuning on 143.050MHz frequency of the Graves surveillance radar located in Dijon, France. http://www.itr-datanet.com/~pe1itr/pdf/The%20143.050MHz%20Graves%20Radar%20a%20VHF%20Beacon.pdf

Juan,

It's likely this site will become unavailable later today and for much of tomorrow (Sat 2 January 2021 - Sun 3 January 2021).

Data Center Power Shutdown

We will be performing an infrastructure enhancement over the weekend of Saturday, Jan. 2 and Sunday, Jan. 3, 2021 which will require a complete shutdown of our campus Data Center. This work is required to support the campus research mission by enabling new research systems and to provide improved resilience for these systems when running on generator power during campus power outages.
Systems will likely be down from 8 a.m. on Saturday, Jan. 2 through 6 p.m. on Sunday, Jan. 3 (times are estimated).
That's 16:00 UTC Saturday until 02:00 UTC Monday.

Excellent news, Puerto Rico government has allocated $8 million to rebuild Arecibo radio telescope!!

And we're back online!


Keep discussing The Search!

Here's hoping for good new discoveries for this New Year!!

Here's hoping they gain further worldwide interest and the budget to rebuild soon and new tech better!

I am running their tasks and getting badges from Bronze to Ruby. The next ones should be Sapphire and Emerald, I believe. Why not Diamonds, which are a girl's best friends?

They do. Diamonds are for 5 & more years of total run time.

Today 1yr ago S@H stopped sending new work for us to crunch. Someone should host a party to mark the event.
I hope all have found new worthwhile projects to help.

I am running WorldCommunityGrid and getting a lot of Badges, from Bronze to Emerald so far. I hope to get some Diamonds in due time. IBM is good at marketing.

Yes, we are faithfully processing other Projects! But no other project is as seminal (!) as looking for alien civilizations! There is just a certain ineffable, dashing excellence about looking for LGM (E.T.) as a member of a giant superbly organized worldwide Terran Cognitive Network! seti@home shall return with even more amazingly efficient software on ever faster computing devices {in far greater numbers} to find those cute elusive little critters!
