European Launch Ambitions, Starquake Mysteries, and the Quest for Hidden Stars

ESA's European Launcher Challenge: The European Space Agency is taking significant steps towards enhancing its commercial launch market, with member states committing over 900 million euros to the European Launcher Challenge. This initiative will see ESA acting as an anchor client, co-funding upgrades for private companies and stimulating competition and innovation in space launch services.

Starquakes and Black Holes: Scientists are uncovering the mysteries of dormant black holes through the study of starquakes, or asteroseismology. Two systems, Gaia BH2 and Gaia BH3, reveal intriguing contradictions in the ages and compositions of their red giant stars, prompting a reevaluation of our understanding of stellar behavior and black hole interactions.

Redefining Time: A philosophical exploration into the nature of time sheds light on the distinction between existence and occurrence. By clarifying the concept of time, researchers challenge long-standing beliefs and offer a new perspective on Einstein's spacetime, suggesting that time should be viewed as a map of events rather than a physical entity.

Hidden Stars and SETI: A new study proposes that the search for extraterrestrial intelligence can be improved by considering previously overlooked stars. By utilizing the Besanc Galactic model, scientists can predict hidden stars in the field of view of telescopes, expanding the search for technosignatures without the need for additional observations.

Wessen Lunar Monitoring Mission: A new mission from Hong Kong, named Wessen, aims to provide continuous monitoring of meteoroid impacts on the Moon. Set to launch by 2028, this lunar orbiter will track the bright flashes caused by impacts, crucial for ensuring the safety of future lunar infrastructure and astronauts as nations plan for lunar bases.
