HARPS-North will be installed at the Galileo National Telescope Site in the Canary islands,as I posted in Italian Cafe.

Hah! Was about to start the exact same thread!

I know seti /seti@home is busy...but I feel like we should be adjusting our data gathering based on this data.

i.e.

In n additional to looking at these candidate planets closely with very good radio telescopes...I think we should be revisiting our algorithms and making sure that they are making the most of this planet data. i.e. we should be looking for different signals from a planet 20 light years away than from planets 100 or 10000 light years away.

I wonder how long until their is a steady supply of targeted planet data for us to crunch on....i feel that is the key to this program'success!

At this moment in time we have to get what Arecibo gives us.

Where they are pointing is up to them,we just piggyback the data.

If SETI@HOME had it's own receiver, it would be able to point
wherever it wanted.

Unfortunately that isn't going to happen in the near future :(

Here is the "Nature" article:

I recall that on one of the Science channel programs they mentioned that the Allen Array when complete will have the effective size of a single antenna one half mile square and that all of it's time is dedicated to SETI research for the SETI Institute. Is it possible that the SETI Institute and the SETI@home organization will work together seeking that first contact sgnal?

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

I would welcome such a cooperation, as would many others. But it does not depend on us, humble crunchers.

Any telescope array will have an effective diameter of the distance between the outermost elements of the array. The light gathering power of the telescope is only as great as the actual combined gathering area of the individual telescopes, but the large effective diameter gives incredible resolving power. I remember my astronomy professor in 1998 mentioning something about an orbital telescope array that would obviously have an effective diameter the size of the orbit around the planet. Anyone know what ever happened to that? I never heard anything else about it after that day in class, and can't find any references to such a project.

The Russians have recently sent a radiotelescope in orbit combining it with one on the ground by interferometry but I haven't read of any result so far.

The idea is still around. Currently they are working on the best way to get satellites to fly in formation.
