Astronomers uncover gas bridge between two dwarf galaxies
Scientists at the University of Western Australia's ICRAR node have discovered a massive bridge of neutral hydrogen gas connecting the dwarf galaxies NGC 4532 and DDO 137. This structure spans 185,000 light-years and is located 53 million light-years from Earth. The finding, part of the WALLABY survey, reveals how interactions with the Virgo cluster strip gas from galaxies.
Dark matter may leave subtle color traces in passing light
Researchers at the University of York suggest that dark matter could subtly tint light red or blue as it passes through, challenging the idea that it is completely invisible. This indirect interaction might allow detection using next-generation telescopes. The finding could simplify the search for the mysterious substance that dominates the universe.

Astronomers find most distant odd radio circle
Astronomers have discovered the most distant and powerful odd radio circle, a massive double-ringed radio structure nearly 10 billion years old. Using citizen science and the LOFAR telescope, researchers propose these cosmic rings form from galactic superwinds rather than black hole mergers. The finding challenges existing theories and highlights the role of human pattern recognition in astronomy.

Discovery challenges chemistry rules on Saturn's moon Titan
Researchers from NASA and Chalmers University have found that polar and nonpolar substances can mix on Titan's surface, defying the 'like dissolves like' principle. This occurs under the moon's extreme cold, where hydrogen cyanide forms stable crystals with methane and ethane. The finding could reshape understanding of Titan's geology and prebiotic chemistry.
Strongest Black Hole Collision Detected
Astronomers detected the strongest black hole collision yet on September 11, 2025, resonating with Einstein's predictions. The event involved massive black holes merging, producing significant gravitational waves. This finding was published in a leading science journal, advancing astrophysics.
Scientists create laptop tool to simulate universe structure
Researchers at the University of Waterloo have developed Effort.jl, a new tool that allows scientists to simulate the universe's large-scale structure using just a laptop. This innovation reduces computation time from days on supercomputers to hours, enabling faster analysis of vast cosmic datasets. The tool emulates complex models like the Effective Field Theory of Large-Scale Structure (EFTofLSS).
