From a press release of the SETI Institute, March 30, 2016:

The SETI Institute has inaugurated a greatly expanded hunt for deliberately produced radio signals that would indicate the presence of extraterrestrial intelligence. Over the course of the next two years, it will scrutinize the vicinities of 20,000 so-called red dwarf stars.

Red dwarfs are dimmer and cooler than the Sun, but they make up the bulk of stars in the Galaxy, increasing the odds of finding life there. They are also, on average, billions of years older than stars than Sun-like stars, so have had more time to potentially produce intelligent species.

The two-year search will be conducted at the Allen Telescope Array in the Cascade Mountains of northern California. This grouping of 42 antennas can currently observe three stars simultaneously.

A new analysis in 2013 of old Hubble Space Telescope images from 2004 has revealed a 12-mile-diameter moon of Neptune, temporarily known as S/2004 N1 (where the S/ means “satellite”).  Its orbital period is 23 hours.

Mark Showalter of the SETI Institute in Mountain View, Calif., discovered the moon on July 1, while studying the faint ring-arcs of Neptune. It is so small and dim that it is roughly one hundred million times fainter than the faintest star that can be seen with the naked eye.
