    339E-359-Ice World
    Jun 3 2025
    Recently Dr. Yossi Shvartzvald led a team which published their discovery of an Earth sized planet using microlensing in the Astrophysical Journal Letters. The newly discovered planet OGLE-2016-BLG-1195Lb orbits a small dim object about 13,000 light years from us. With only 7.8% of the Sun's mass the new planet's star may be a brown dwarf and not a star at all. At about the same distance from its star as we are from the Sun this new planet is likely to be an ice ball world colder than Pluto.

    In a recent paper published in Nature Astronomy entitled “Surveys of the scientific community on the existence of extraterrestrial life” Dr. Peter Vickers and his team of 10 co-authors report the results of their survey of the lead authors for the past 10 years in the top three astro-biological journals. These researchers sought to measure if their sample group of scientists thought it likely that 1) simple life, and/or 2 ) life more complex than terrestrial bacteria, and/or 3) Intelligent life comparable or superior to human beings exists outside of Earth.

    When I discovered 2014 JO25 with the NASA funded Catalina Sky Survey's 60 inch telescope on May 5, 2014, it appeared as a single point of light as it moved past us. As 2014 JO25 approached the Earth from the direction of the Sun in 2017, no-one had any idea that it is really a double asteroid system nearly a mile in diameter.
