| 22.04.2024 | “solar system is “squashed” or “dented”– that the bubble carved into interstellar space by the solar wind is not perfectly round” Voyager Project Scientist Edward Stone of the California Institute of Technology, Pasadena, Calif. boundary layer interstellar space: “solar wind termination shock, where the solar wind is abruptly slowed by pressure from the gas and magnetic field in interstellar space.” “the shock “sloshes” back and forth like surf on a beach” “In a normal shock wave, fast-moving material slows down and forms a denser, hotter region as it encounters an obstacle. However, Voyager 2 found a much lower temperature beyond the shock than was predicted. This probably indicates that the energy is being transferred to cosmic ray particles that were accelerated to high speeds at the shock.” Eric Christian, Voyager Program Scientist at NASA Headquarters, Washington.https://science.nasa.gov/missions/voyager-program/voyager-2-proves-solar-system-is-squashed/ | |

| 3.12.2023 | “These disks pull together dust grains that grow into pebbles and eventually combine to form a solid planetary core. Once the core is formed, the planet can gravitationally pull in the solid dust, as well as surrounding gas such as hydrogen and helium. But it needs a lot of mass and materials to do this successfully. This way to form planets is called core accretion.” BUT: “A star as low mass as LHS 3154, nine times less massive than the sun, should have a correspondingly low-mass planet forming disk.” “A different planet formation theory, gravitational instability—where gas and dust in the disk undergo a direct collapse to form a planet—also struggles to explain the formation of such a planet without a very massive disk.” Massive planet too big for its own sun pushes astronomers to rethink exoplanet formation | Convection vs. Accretion / Solar System Formation |

The idea of the journal is similar to the idea of a bookkeeping journal. While in bookkeeping journal daily business transactions are recorded in one sentence in this journal new insights in Astronomy research are collected. Further similar to bookkeeping these entries will be entered in the corresponding categories / content yet to be established.
