Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain. The same seven-dimensional geometry behind this idea could also help explain why elementary particles have mass.

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet's crust and allowing hot water to flow through it. These long-lasting, life-friendly environments may have covered much of the early Earth, turning cosmic destruction into an unexpected opportunity.

A strange gamma-ray glow at the center of the Milky Way has long sparked debate over whether it comes from hidden neutron stars or elusive dark matter. By applying machine learning to more than a million simulated observations, researchers included photon energy data for the first time and reached a different conclusion than many earlier studies.

Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The researchers say future missions should focus not only on finding life, but also on understanding how signs of life could be missed.

A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type Ia supernovae and modeling their environments in unprecedented detail, researchers can estimate cosmic distances with near-spectroscopic accuracy. The technique is designed for the flood of data expected from the upcoming Vera C. Rubin Observatory and may greatly improve our understanding of dark energy.

Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points to a new phase of matter that goes beyond established quantum theories and could expand the possibilities of quantum simulation.

Astronomers have finally cracked the mystery of the famous “Pink Planet,” a strange world 57 light-years away that has puzzled scientists for more than a decade. Using the James Webb Space Telescope, researchers discovered that its atmosphere contains water vapor, methane, carbon dioxide, ammonia, and something never directly confirmed before in such an object: salty clouds.
