In the past similar approaches have been used to crack encryption codes or calculate the largest prime number,
but this is the first time such a scheme has been used for analysing raw scientific data. The system works by fooling the
computer into running a screen-saver package called SETI@home every time the
machine is idle.
As soon as user returns to work,
the
program shuts down.
As most computers are only used 8 hours a day,
this gives the
project 16 hours a day of computer time.
The large number of machines used in the
project will help SETI watchers to analyze smaller parts of the
frequency spectrum more thoroughly than current SETI projects.
The approach will also be ten times more sensitive than previous experiments. So far the
researchers have released Windows and
UNIX prototypes of the
software,
and
a Mac version is planned.
Within the
next six months the
team hope to finish a more polished package that will also provide three different types of visualization of the
experiment: science mode will describe the
analysis taking place on the
local machine and
the
significance of any results;
sky progress mode will show what parts of the
sky are being covered by the
entire experiment,
and
summarize all the
potentially interesting results found so far;
and
Earth progress mode will focus on the
people participating in the
experiment,
with a view of the
earth showing all the
individuals and
organizations currently participating.
Once up and
running,
the
experiment is expected to run for at least two years.
'Idle' machines look for ET
Jul 24, 1998
Researchers looking for signs extra-terrestrial intelligence are planning to use idle computers connected to the Internet to process their data. Over 115, 000 volunteers have already agreed to allow their computers to be linked together to create a 'virtual' supercomputer to look for intelligent life. This virtual machine will analyze data collected as part of ongoing astronomical observations by the Arecibo radio telescope in Puerto Rico, the largest radio telescope in the world. The Search for Extra-Terrestrial Intelligence at Home - or SETI@home - looks for narrow-band signals associated with alien intelligence, such as radio or television signals. The project is organized by the University of California at Berkeley.
