SETI: April 2017


Day Two of Breakthrough Discuss opened with Michaƫl Gillon describing the discovery of TRAPPIST-1, which has seven temperate planets, including three in the habitable zone.

The first day of Breakthrough Discuss 2017 explored planets around nearby stars and their potential for life. Charles Alcock opened the conference with the statement that, "The far-fetched ideas of today are the discoveries of tomorrow," and Peter Michelson emphasized that the last century of scientific investigation has transformed questions about origins from the realm of metaphysics to a place where they can be investigated observationally.

Breakthrough Listen - the initiative to find signs of intelligent life in the universe - has released its 11 events ranked highest for significance as well as summary data analysis results.

We searched high resolution spectra of 5600 nearby stars for emission lines that are both inconsistent with a natural origin and unresolved spatially, as would be expected from extraterrestrial optical lasers.
