New simulation challenges leading explanation for why galaxies stop forming stars

For decades, astronomers have cast galaxy mergers as the universe’s ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt. Upending this long-held belief, new research from Florida International University suggests most galaxies don’t “die” in spectacular cosmic pileups after all.

Jellyfish nebula may be the scene of two stars going supernova

The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary star system in which both stars have gone supernova.

Two-color lasers aim electron currents through semiconductor with no electric field

Researchers at the University of Michigan have created a device that enables them to control the flow of electrons through a semiconductor using only laser light—no electrical power source required. The device was built to explore fundamental physics and realize a previously unobserved behavior, but it could also open doors for new applications in areas […]

Quantum sensing microscope illuminates transistor design

Artificial intelligence faces an energy crisis stemming from a physical traffic jam inside modern computer chips. Processors must continually shuffle data, such as the billions of parameters in complex models, between separate computing and memory nodes. This traffic jam, known as the “von Neumann bottleneck,” hinders the speed and energy efficiency of advanced processors.

Antarctic 12-m Terahertz Telescope project to uncover hidden galaxy formation

A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by University of Tsukuba, could uncover between 1 and 10 million dusty star-forming galaxies throughout cosmic history.

Frozen fiber couples light and sound 1,000 times more strongly than standard glass fibers

Researchers have developed a new type of optical fiber by freezing a glass capillary filled with liquid. It guides light and sound waves simultaneously and enables highly efficient coupling between them. The high coupling strength lowers the energy consumption of photonic neuromorphic computing schemes and quantum signal processing applications by several orders of magnitude.

When a SpaceX rocket crashes into the moon, scientists will be watching

On Aug. 5, 2026, an abandoned piece of space junk is predicted to crash into the moon near a spot called Einstein Crater. Astronomers will be watching because the collision and aftermath may be visible from Earth.

Finding Venus zone planets with PLATO will show us how habitable planets evolve

Dreams of finding a sort of Earth 2.0 motivate much of the thinking around the search for exoplanets. But there is more to exoplanet science than searching for potentially habitable worlds. Scientists need a deeper understanding of the overall exoplanet population to understand the cosmos.

Scientists use dual-frequency images to explore black hole plasma physics

The first-ever image of a black hole—a glowing, ring-like structure at the heart of galaxy M87—was unveiled to the world in a landmark moment in 2019. Now, researchers have taken the next big step—moving beyond capturing a picture of the black hole to understanding its physics through dual-frequency images.
