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
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.

337E-356-Seeds
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.

849-Europa-Clipper
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.
