Space-based solar power (SBSP) has long been the dream of many space enthusiasts and energy economists. However, the reality of economic constraints has long left any practice projects on the ground. There has been plenty of discussion about how to lower the cost of entry to build the kind of space-based solar power satellite described by John Mankins in his books and articles. However, even with the advent of lower costs to orbit thanks to reusable rockets, the economic case for SBSP is still not great simply due to the sheer amount of mass required to get into orbit. Unless we get that mass from somewhere else, with a smaller gravity well. Astrostrom, which means something like "Star current" in German, is an organization based in Switzerland that hopes to make space-based solar power a reality.

Astronomy has entered the age of gravitational waves. While there are plenty of differences between gravitational wave astronomy and typical waves of the electromagnetic spectrum, they share one similar feature: frequency. While we have detectors for a wide range of electromagnetic frequencies, gravitational wave detectors only focus on a narrow band of relatively low-frequency signals. That will change with the upgrade of the GEO600 gravitational wave detector located at the Max Planck Institute for Gravitational Physics.

We know that our Milky Way galaxy hosts a supermassive black hole (SMBH) in its center. Astronomers think most spiral galaxies do, and that SMBHs coexist and co-evolve with their host galaxies. However, they haven't been able to find them in all spirals. M83, the Southern Pinwheel Galaxy, has always been puzzling because scientists haven't seen any evidence of an SMBH in its center. The JWST may have finally found some.

It’s one straight out of the history books. After over 50 years in space, the late Soviet Union’s Kosmos-482 mission is set to reenter the Earth’s atmosphere, early next month. Stranded in Earth orbit, there are just a few weeks remaining to see this enigmatic relic of a bygone era.

Where do the heavy elements in the Universe come from? While we know they are formed in colliding neutron stars and likely in supernova explosions, astronomers have now identified a surprising additional source: magnetars. These highly magnetised neutron stars emit powerful flares, which may result from neutrons fusing into heavier elements. This process could explain the presence of elements like gold early in the Universe's history.

What probes can be used to explore the depths of Jupiter’s icy moon, Europa, and other ocean worlds throughout the solar system? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers participated through the Ocean Worlds Reconnaissance and Characterization of Astrobiological Analogs (ORCAA) project to investigate how cryobots could be used to explore the oceans of other worlds in our solar system.

Stars don't exist in isolation. They have siblings and exist in clusters, associations, and groups. The ESA's Gaia mission found an unusual group of stars rapidly leaving its birthplace behind and dispersing into the wider galaxy. While that's not necessarily unusual behaviour, it is for such a large group. Could supernovae explosions be responsible?

Getting missions to land successfully on the Moon has been difficult. Recent missions, such as IM-1 and IM-2, which the private company Intuitive Machines completed, have been qualified successes at best, with both landers settling at unintended angles and breaking parts of them off along the way. Such experiences offer excellent learning opportunities, though, and NASA is confident that a third time might be a charm for a flawless mission. There will be a lot riding on IM-3, the third Commercial Lunar Payload Services (CLPS) mission, including a set of rovers and ground station for a NASA experiment called the Cooperative Autonomous Distribution Robotic Exploration (CADRE), which recently passed its Verification and Validation (V&V) test for one of it's most essential parts. This software architecture handles tasks for each rover and binds them into a cohesive whole.

A rare stellar occultation, which happens only once every 30 years, allowed astronomers to observe Uranus and learn more about the composition of its atmosphere and rings.

As the second-largest object in the main asteroid belt, Vesta attracts a healthy amount of scientific interest. While smaller asteroids in the belt are considered fragments of collisions, scientists think Vesta and the other three large objects in the belt are likely primordial and have survived for billions of years. They believe that Vesta was on its way to becoming a planet and that the Solar System's rocky planets likely began as protoplanets just like it. But new research is casting doubt on that conclusion.
