Supernovae and GRBs also make great natural beacons for SETI

LJK — 6/21/2006 5:27:17 PM (archived)

If you want to get the attention of someone in the galaxy many light
years away, and you don't have the money or the public support to
set off your own giant fusion bomb, using a supernova or GRB is a
great way to get someone else's attention at interstellar distances.

Aim your signal in a cone opposite the direction of the SN or GRB. The
assumption is any ETI with a culture that is into astronomy and has the
technology to detect signals may pick up your transmission while studying
the celestial blast.

See here:

I don't know how many astronomers on this planet look for such signals
when they detect and study SNs and GRBs, but they should consider it.
Serendipidity is what found us pulsars, plus being the first to find an ETI
looks good on your resume, too.
