Lunar Impact Flashes NASA Artemis
NASA의 Artemis 2 임무 중 우주비행사들이 달 표면에서 발생하는 유성 충돌로 인한 순간적인 빛의 섬광을 직접 관측했다. 이 관측은 달의 충돌 빈도, 에너지 방출, 분화구 형성 과정을 이해하는 데 중요한 실시간 데이터를 제공하며, 특히 달의 지구 반대편에서 이루어진 관측이라는 점에서 의미가 크다. 지상 시민 과학자들과의 협업을 통해 관측 데이터의 신뢰성을 높였고, 이러한 연구는 미래 달 기지 건설 시 미세운석 충돌 위험 평가와 방호 설계에 활용될 전망이다. Artemis 임무는 앞으로도 달 충돌 활동 모니터링과 탐사 전략 수립에 핵심적인 역할을 할 것이다.

Weekly Update from the Open Journal of Astrophysics – 20/09/2025
It’s Saturday again, so it’s time for a summary of the week’s new papers at the Open Journal of Astrophysics. Since the last update we have published two new papers, which brings the number in Volume 8 (2025) up to 136, and the total so far published by OJAp up to 371.
The first paper to report this week is “The Moon as a possible source for Earth’s co-orbital bodies” by Rafael Sfair, L. C. Gomes, O. C. Winter & R. A. Moraes (São Paulo State University, Brazil), G. Borderes-Motta (Astronomical Institute of the Czech Academy of Sciences, Czech Republic) and C. M. Schäfer (Universität Tübingen, Germany). This paper was published on Monday 15th September, in the folder Earth and Planetary Astrophysics, and it presents a numerical exploration of the ejection velocities and launch locations necessary for lunar ejecta to evolve into Earth’s co-orbital bodies.

The second paper this week, published on Friday 19th September in the folder Solar and Stellar Astrophysics, is “Jet-Driven Formation of Bipolar Rings in Planetary Nebulae: Numerical Simulations Inspired by NGC 1514” by Muhammad Akashi, Ealeal Bear, and Noam Soker (Technion, Haifa, Israel). This paper presents evidence from numerical simulations notion that jets play a substantial role in shaping planetary nebulae (PNe).
