Galactic collisions are events of breathtaking proportions. The Supermassive Black Holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, they could eventually get “kicked” out of the center of their galaxy - and finding these “recoiling” black holes has been a challenge of cosmology for decades. A new paper, available on arXiv by an international team, used a novel idea to track down these fast-moving behemoths.

The prototype ngVLA antenna tested its systems by observing and tracking the Crab Nebula, also known as Taurus A (3C144), the remnant of an exploded star.

Microsoft’s announcement of a new quantum computing breakthrough with its Majorana 2 chip continues a trend of bold claims followed by scant evidence

It might not seem like it, but the Moon is constantly being both sandblasted and baked. Its lack of a thick atmosphere allows micrometeorites to impact the surface at speed, and the solar wind isn’t held back either, baking the regolith with a constant flow of high-energy particles. These processes drive what is called “space weathering”, and it can drastically alter the physical and chemical properties of the lunar dirt over the course of billions of years. And we’re finally getting a better sense of what that means in practice thanks to two new papers from researchers at the Chinese Academy of Sciences and Peking University, which used advanced electron tomography and spectroscopic techniques to analyze samples returned from the Chang’e-5 mission to the near side of the Moon.

Our understanding of the electromagnetic spectrum goes back to Isaac Newton, but astronomers are still finding new ways to employ it. Astrophysicist Emma Chapman explores how much these invisible waves can reveal to us about the cosmos – and whether they might show us that we’re not alone

Though it's a toxic chemical, hydrogen cyanide (HCN) is also important for the development of life. It's a precursor to things like amino acids and nucleic acids and plays a central role in theories of the origin of life on Earth. Recently, difficult questions have been asked about how it could have formed on the early Earth. But the authors of new research in PNAS seemed to have figured it out.

This order asks artificial intelligence companies to give the U.S. government up to 30 days to assess frontier models before they are released

The search for any sign of life on Mars continues. In the latest update, a new data release from Curiosity’s Chemistry and Mineralogy (CheMin) - essentially the rover’s portable X-ray diffraction lab - and published in a paper in Science, analyzes 20 different rock samples from various elevations of Mount Sharp, the mountain in the center of Gale Crater that Curiosity has been slowly climbing. In the paper, the researchers describe how the size of the crystals in those samples could help scientists determine where to look for evidence that life might have evolved on the Red Planet.

Astronauts Sophie Adenot of ESA (European Space Agency) and Jack Hathaway of NASA, both Expedition 74 flight engineers, look out a window in the cupola, monitoring the automated approach and docking of the SpaceX Dragon cargo spacecraft to the International Space Station on May 17, 2026. The orbital outpost was soaring 259 miles above the Indian Ocean just west of the Maldives at the time of this photograph.
