    From SETI: “No Signals from Newest Kepler Planet”

    A newly discovered planet has been observed with the Allen Telescope Array in a search for radio signals that would betray technically sophisticated inhabitants, but no transmissions have been detected.

    The planet is known as Kepler 116454b, and orbits an orange dwarf star in the constellation Pisces. It is 180 light-years away.

    Jon Richards, of the SETI Institute’s Center for SETI Research, used the Allen Telescope Array to look for signals over the frequency range of 1000 – 2250 MHz.

    In May, 2013 the Kepler space telescope suffered a mechanical failure that ended its ability to accurately aim at the sky. But the telescope has resumed its search for planets in a new mode, using the pressure of sunlight to help it steady its gaze on the sky. Kepler 116454b is the first planet to be found by the reincarnated telescope, and its discovery was announced just before Christmas.

    The planet orbits its home star in 9 days in an orbit three times smaller than Mercury’s orbit around the Sun. Consequently, temperatures on this world – which is a so-called “super Earth” and larger than Earth but smaller than Neptune – are expected to be too hot for life as we know it.

    Nonetheless, and as centuries of experience have shown, observation sometimes trumps expectation, and that is why new exoplanets – whether they seem promising for life or not – are routinely observed by the SETI Institute with the Allen Telescope Array.

    The observations of Kepler 116454b will continue at higher frequencies, Richards notes.

    From SETI Institute: Meet Dr Jill Tarter 

    Jill Tarter is my candidate for Miss Universe.

    i1

    “Astronomer Dr. Jill Tarter is Director of the Institute’s Center for SETI Research, and also holder of the Bernard M. Oliver Chair for SETI (Search for Extraterrestrial Intelligence). She is one of the few researchers to have devoted her career to hunting for signs of sentient beings elsewhere, and there are few aspects of this field that have not been affected by her work. Jill was the lead for Project Phoenix, a decade-long SETI scrutiny of about 750 nearby star systems, using telescopes in Australia, West Virginia and Puerto Rico. While no clearly extraterrestrial signal was found, this was the most comprehensive targeted search for artificially generated cosmic signals ever undertaken. Among her numerous distinguished awards and recognitions, Jill received the 2009 TED Prize, which will empower Jill and her team to take SETI research to an entirely new and broader level.

    Being as much of an icon of SETI as Jill is, perhaps it is not surprising that the Jodie Foster character in the movie Contact is largely inspired by this real-life researcher.”

    Now, the above is from Jill’s bio interview page at the SETI Institute web site. There is much more, so you should go there and read it.

    I went looking for more just plain facts. Usually, Wikipedia is a sure bet. Not this time. Short and sweet. Not even much of Jill’s CV. But, at SETI Institute, there is a really good listing of Jill’s accomplishments. Check it out.
