This galaxy is not only pretty -- it's useful.

Two Chinese astronauts spent more than six hours outside the Tiangong space station on Friday (Aug. 15), installing a debris shield on the third spacewalk of the Shenzhou 20 mission.

In a recent paper, researchers followed the trajectories of 1I/`Oumuamua, 2I/Borisov, and 3I/ATLAS - three installer objects that have entered the Solar System in the past decade - to constrain their possible origin. Through a series of Monte Carlo simulations, they came up with predictions of where they came from and how old they are.

Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we’re not as familiar with. Scientists think they understand how the most important Moon in our solar system (our own) formed, but its violent birth is not the norm, and can’t explain larger moon systems like the Galilean moons around Jupiter. A new book chapter (which was also released as a pre-print paper) from Yuhito Shibaike and Yann Alibert from the University of Bern discusses the differing ideas surrounding the formation of large moon systems, especially the Galileans, and how we might someday be able to differentiate them.

The Universe's early galaxies were engulfed in halos of high-energy cosmic rays. It's likely because they had tangled and turbulent magnetic fields. These fields accelerate cosmic rays to higher energies.

China took a step closer to the Moon, with the first short test for their crewed lunar lander. The test was completed on Wednesday, August 6th at a facility in China’s northern Hebei Province, and lasted just under 30 seconds. The tethered test successfully demonstrated the integration and performance of key systems, simulating descent, guidance, control and engine shutdown. This marks the first test for a China’s Manned (crewed) Space Agency (CMSA’s) human-rated lander.

Taking a walk is great for inspiration. There have been numerous studies about how people think more clearly on walks, and how new ideas come to them more frequently while doing so. That’s part of the reason some of the most famous minds in history included a daily walk in their schedule. Just such an inspiration must have happened recently to Nicholas Heinz, a scientist at NASA’s Jet Propulsion Laboratory (JPL) in California. On a hike in Arizona he found a rock that could be used as an analog of a unique one found by the Perseverance rover on Mars - and decided to take it back to his lab to study it.x

Climate change isn't just transforming weather on Earth's surface, it’s also fundamentally altering how space weather affects the thousands of satellites orbiting our planet. New research reveals that rising carbon dioxide levels will dramatically change how geomagnetic storms impact the upper atmosphere, creating both opportunities and challenges for the satellite industry in the decades ahead.
