    Jun 6 2025
    The good news is a Mars landing by human colonists and their equipment seems technically feasible given a large budget of cash and grit.

    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.

    851-Scientists Views Odds of Aliens
    May 30 2025
    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.

    338E-357-Double Trouble
    May 27 2025
    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.

    Since there is a world wide market for meteorites some of which can be sold for millions of dollars, on line, the question of ownership becomes important.

    337E-356-Seeds
    May 20 2025
    When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life.

    NASA’s Europa Clipper was launched October 14, 2024 on a mission to conduct a detailed study of Jupiter’s Moon Europa. The space craft will travel some 1.8 billion miles and should reach Jupiter in April 2030. This mission will begin to tell us if life as we know it can occur relatively close to home.

    336E-355-2 Suns
    May 13 2025
    The NASA Kepler Spacecraft has discovered more than 2,000 planets which have been confirmed to be orbiting distant stars. It performs this remarkable feat by imaging more than 145,000 stars simultaneously to observe and measure the tiny dips in light which occur as a planet passes in front of its star. Astronomers have long known that many of the solar systems in the Milky Way have more than one star. To investigate the possibilities for life in a double star system, Dr Max Popp a scholar at Princeton University and Dr. Siegfried Eggl of Germany's Max Plank Institute substituted the real giant planet orbiting the stellar pair Kepler 35A and B with an Earth sized one orbiting the Kepler AB pair with periods between 341 and 380 days. Their detailed analysis is published in the journal Nature Communications.
