Neutron Stars Could Serve as Cosmic Thermometers for Dipole Dark Matter Featured image: [Artist’s impression of a neutron star with dark matter particles interacting near its surface; credit: NASA/JPL-Caltech] A new study published on arXiv proposes using neutron stars as highly sensitive thermometers to detect dipole dark matter, offering a novel observational window into one […]

Primordial Black Holes Could Link Two Gravitational Wave Signals Across Frequency Bands Featured image: [Artist’s impression of a primordial black hole binary system emitting gravitational waves; credit: NASA/JPL-Caltech] A new study establishes a model-independent connection between two distinct gravitational wave signals originating from primordial black holes, potentially allowing astronomers to probe the same early universe […]

FAST Telescope Searches Interstellar Object 3I/ATLAS for Alien Radio Signals China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the world’s largest single-dish radio telescope, has conducted the first search for periodic radio signals from 3I/ATLAS — the third confirmed interstellar object to visit our solar system. No artificial signals were found, but the search itself represents a […]

NASA’s Hubble Spots a Star-Spangled Cosmic Scene for July 4 NASA’s Hubble Space Telescope has marked America’s 250th anniversary with an appropriately patriotic image: a star-spangled view of the globular cluster Messier 3, a brilliant swarm of more than 500,000 stars in the constellation Canes Venatici. Released on July 3, 2026, the image shows the […]

SVOM Observatory Delivers Early Results: Microquasars, Magnetars, and More The Space-based multi-band astronomical Variable Objects Monitor (SVOM), a joint Chinese-French astrophysics mission, has released its first major batch of science results from the Observatory Science program. The findings, published in a paper submitted on July 1 to Research in Astronomy and Astrophysics, demonstrate that SVOM […]

Could Humans Explore Titan, or Will Humanoid Robots Do It for Us? Featured image: [Artist’s illustration of NASA’s Dragonfly rotorcraft on the surface of Titan with Saturn in the background; credit: NASA/JHU-APL] Saturn’s largest moon Titan is one of the most compelling destinations in the solar system, a world with a thick nitrogen atmosphere, liquid […]

New Study of the Bullet Cluster Challenges the Existence of Dark Matter Featured image: [Composite image of the Bullet Cluster showing X-ray gas in pink and gravitational lensing mass in blue; credit: NASA/CXC/STScI/ESO] A new study led by the University of Bonn has reopened one of the most contentious debates in modern cosmology: whether dark […]

This Giant Planet Survived the Death of Its Star, JWST Reveals How Featured image: [Artist’s impression of a giant planet orbiting a white dwarf, with the planet appearing as a dark silhouette against the bright stellar remnant; credit: NASA/ESA/STScI] A giant planet that somehow survived the violent death of its host star has finally given […]
