In 2010, physicist Stephen Hawking voiced concern about the possibility that we might contact extraterrestrial life by transmitting signals into space.
However, SETI senior astronomer Seth Shostak told us that it's too late to consider whether we should send such transmissions, because we've already been doing it for decades.

Israel’s strike on Iran on Friday morning will not come as a surprise to Western observers – but it will cause great concern in Washington and London as the region tips closer towards an all-out war.
If this Israeli attack on Iran is no more than it presently appears to be, then it is rather well modulated. If the airbase at Isfahan has been attacked - home to the 8th Tactical Air Wing of the Iranian Air Force, and not a Revolutionary Guard installation - then the Israelis are making their point against a conventional military target. It is not an enrichment plant or a reactor, but the wide-ranging nuclear research conducted there involves some 3,000 Iranian nuclear scientists.
Israel’s presumed counterstrike against Iran has proved Joe Biden and David Cameron wrong in their insistence that Israel should just “take the win”. Instead, it fought back – and yesterday Iran was trying to pretend that nothing had happened.
