Antimatter in astronomy and cosmology: the early history.
Ann Sci

Niels Bohr Institute, Copenhagen University, Copenhagen, Denmark.
So-called antimatter in the form of elementary particles such as positive electrons (antielectrons alias positrons) and negative protons (antiprotons) has for long been investigated by physicists. However, atoms or molecules of this exotic kind are conspicuously absent from nature. Since antimatter is believed to be symmetric with ordinary matter, the flagrant asymmetry constitutes a problem that still worries physicists and cosmologists.

The origins of life remains an unsolved mystery for all of humankind which requires a uniquely interdisciplinary approach incorporating many different subfields from astronomy, to geology, to chemistry, to biology, and beyond. One of these subfields which contributes greatly to understanding of various aspects of the origins of life is biophysics. As part of the 21st IUPAB/62nd BSJ Joint Congress in Kyoto, Japan, a symposium on the Origin of Life was held on June 28, 2024, featuring invited and contributed presentations on various aspects of origins of life research from Japan and around the world.

The formation of our solar system occurred approximately 4.6 billion years ago as a result of the gravitational collapse of a small portion of a giant molecular cloud. The origin of life on Earth is yet to be fully understood.

Article Synopsis
- The study of single crystal paleointensity (SCP) indicates that the Moon did not have a sustained core dynamo, with some Apollo basalts suggesting an episodic dynamo instead.
- Analysis of ancient Apollo basalts reveals they record unrealistic magnetization levels and indicate null magnetic fields, implying they do not support the idea of a long-lasting lunar dynamo.
- The findings suggest that the lunar surface may contain evidence of Earth's early atmosphere, potentially trapped in regolith, making it a valuable location for future research.
