315 Billion-Ton Iceberg Breaks Off Antarctica (bbc.co.uk)
jimminy_cricket quotes a report from the BBC:The Amery Ice Shelf in Antarctica has just produced its biggest iceberg in more than 50 years. The calved block covers 1,636 sq km in area -- a little smaller than Scotland's Isle of Skye -- and is called D28. The scale of the berg means it will have to be monitored and tracked because it could in future pose a hazard to shipping. Not since the early 1960s has Amery calved a bigger iceberg. That was a whopping 9,000 sq km in area. Amery is the third largest ice shelf in Antarctica, and is a key drainage channel for the east of the continent. D28 is calculated to be about 210 meters thick and contains some 315 billion tons of ice

New Theory On Mysterious Oumuamua Space Object Revealed (newsmax.com)
In 2017, astronomers discovered a peculiar object in the solar system called 'Oumuamua that was somehow ejected into our solar system from some chain of unfortunate events. "Now, astronomers have hypothesized that something like 'Oumuamua can come from a still-forming system, and a population of giant planets can have just the right gravitational effects to spread pieces of debris across the galaxy," according to the Live Science article written by astrophysicist Paul Sutter. From a report:The dull shaped object is only a few hundred feet long and very thin. It has a very dull red color. Live Science noted older solar systems don't eject enough raw material to saturate the galaxy. But young solar systems are different. Particularly, those with Neptune-like planets, on the edge of a solar system with reservoirs of comets around it. Enough interaction with the debris field and a Neptune-like planet could send objects like Oumuamua flying out into interstellar space. But Sutter cautions this is strictly a hypothesis. "The more we watch the skies, the more interstellar interlopers we are sure to find," he wrote.

Organic Compounds Found In Plumes of Saturn's Icy Moon Enceladus (space.com)
Scientists have detected new types of organic compounds in the plumes that have been erupting from Saturn's icy moon Enceladus. Space.com reports:NASA's Cassini spacecraft collected invaluable data and images of Saturn and its moons over the approximately 20 years that the mission took place. While the mission ended on Sept. 15, 2017, with the craft diving toward the planet in a "Grand Finale," scientists continue to study the wealth of data that they gathered during the mission. In one new study, scientists looked at the material that Enceladus ejects from its core using hydrothermal vents. The material mixes with water in the moon's subsurface ocean and is then emitted as water vapor and icy grains.
In studying these ejections, the team found organic molecules that are condensed onto these grains and which contain oxygen and nitrogen. This comes after the first discovery of organics on the moon in 2018. Similar compounds on Earth take part in the chemical reactions that form amino acids, which are the organic compounds that combine to form proteins and are essential to life as we know it. On Earth, energy, or heat, from hydrothermal vents on the ocean floor helps to fuel these amino acid-producing reactions. With these findings, scientists have suggested that perhaps something similar is happening on Enceladus and the hydrothermal vents under its subsurface ocean are aiding in the creation of amino acids on the moon."If the conditions are right, these molecules coming from the deep ocean of Enceladus could be on the same reaction pathway as we see here on Earth. We don't yet know if amino acids are needed for life beyond Earth, but finding the molecules that form amino acids is an important piece of the puzzle," Nozair Khawaja, who led the research team from the Free University of Berlin, said in a statement.

- New note - On 1807.06, I ceased daily transmission of my Hey Mom feature after three years of daily conversations. I plan to continue Hey Mom posts at least twice per week but will continue to post the days since ("Days Ago") count on my blog each day. The blog entry numbering in the title has changed to reflect total Sense of Doubt posts since I began the blog on 0705.04, which include Hey Mom posts, Daily Bowie posts, and Sense of Doubt posts. Hey Mom posts will still be numbered sequentially. New Hey Mom posts will use the same format as all the other Hey Mom posts; all other posts will feature this format seen here.
