Red Giant Stars Can't Destroy All Gas Giants. Some Are Hardy Survivors
Astronomers haven't found many gas giants orbiting white dwarfs. But is that because they're so difficult to spot? Or is it because their survival rate is so low? New research probes the issue.

ESA's sustainability ambition
Space activities are unlike any others. They interact not just with Earth, but with three interconnected environments: Earth, Earth’s orbit, and the Moon and deep space. On Earth, we aim to reduce the space sector’s environmental impacts while maximising the societal and environmental benefits of our missions. In orbit, we manage space debris and collision risks to maintain safe and secure operations. For the Moon and deep space, we are laying the foundations to minimise the impact of our missions on and around other celestial bodies.
Guided by our core values, ESA is committed to making its activities more sustainable, redefining how space activities are conceived, executed and shared with the world. Our objective is clear: to address the most pressing challenges and implement ambitious changes, both in our own practices and in close collaboration with our partners.
Looking ahead, in support of Strategy 2040, ESA is determined to lead through ambition, action and collaboration, building a future where space is not only a domain of opportunity but also a model of sustainability, responsibility and global unity.

Reading the Moon’s Diary, One Speck of Dust at a Time
Magnetism on the Moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts to detect it in returned regolith samples blended together all of the rocks in those samples, leading to confusion about the source - whether they were caused by a strong inner dynamo in ages past, or by powerful asteroid impacts that magnetized the rocks they hit. A new study from Yibo Yang of Zhejiang University and Lin Xing of the Chinese Academy of Sciences, published recently in the journal Fundamental Research, shows that the right answer seems to be - a little of both.
