Before Artemis astronauts land on the moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the moon, will support astronaut safety and mission success for crewed lunar landings.

Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding how they affect their immediate vicinity and the galaxies that surround them. A new paper by Tegan Thomas of the University of Virginia and her colleagues, available on the arXiv preprint server, has good news and bad news on that front. The bad news is that we currently can’t determine how fast black holes are actually spinning. The good news is that, hopefully in the next few years, we will have a new tool that will allow us to do so.

Fabrics are made by repeatedly intertwining yarns into characteristic patterns. Many of their properties, such as stretchiness, arise not only from the material itself but also from how the yarns are arranged and entangled. Such properties illustrate how topology—the underlying patterns of connectivity and entanglement within a structure—can shape a material’s overall behavior. Understanding these relationships could help researchers design materials with tailored properties through the design of their topology.

Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR) back then was up to 100 times greater than it is today. For the SFR to be so high, gas had to move through galaxies efficiently.

What does it take to catch up with a small, tumbling rock hundreds of thousands of kilometers from Earth? For China’s Tianwen-2 mission, the answer was a 400-day chase covering roughly 1 billion kilometers (621 million miles) of deep space—one that has just ended in success. The China National Space Administration has confirmed that the probe has rendezvoused with the near-Earth asteroid Kamoʻoalewa, also known as 2016 HO3, closing to within about 20 kilometers (12 miles) and officially beginning its scientific exploration phase.

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious because, in the world we see around us, light appears to follow a single, clear path.

Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard’s Star—the sun’s closest neighbor after Alpha Centauri, just under six light-years from Earth.

A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that the catastrophic breakup of the Eulalia parent body could be linked to an impact shower that struck the terrestrial planets about 800 million years ago. The work is published on the arXiv preprint server.

The UK Space Agency and space startup Vast just signed an agreement to send Paralympic sprinter and below-knee amputee John McFall into orbit as early as 2027. Most coverage framed it as a victory for inclusion. As a space health researcher, I think something far more interesting happened.

On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time later, a meteorite weighing more than 2 pounds crashed through the roof of a house in the town of Hillsborough, New Jersey.

NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among the oldest terrain ever examined by a Mars rover.
