An international team of astronomers addressed the mystery of the "Little Red Dots" (LRDs) observed by Webb. They conclude that they are likely to be "black hole stars," the early seeds of supermassive black holes (SMBHs) we see at the center of galaxies today. Their findings have implications for our understanding of cosmic evolution.

A mysterious excess of gamma rays in the middle of the Milky Way may come from dark matter particles smashing into one another and annihilating

Samples from one of the Apollo 17 drive tubes was recently opened and analyzed by Brown University researchers, who found surprising sulfur isotopes signatures inside.

Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the red planet. By recreating Mars-like conditions in the lab, a team of researchers from NASA Goddard Space Flight Center and Penn State demonstrated that fragments of the molecules that make up proteins in E. coli bacteria, if present in Mars' permafrost and ice caps, could remain intact for over 50 million years, despite harsh and continuous exposure to cosmic radiation.

After decades of speculation, two writers uncovered the answer to the Kryptos code’s final cipher

Hundreds of people at the U.S. Centers for Disease Control and Prevention have received layoff notices, and work at many federal laboratories has been suspended

In certain circumstances, losses create a sure path to victory, an idea with implications for biology and cancer therapy

Mathematicians thought that they understood how rotation works, but now a new proof has revealed a surprising twist that makes it possible to reset even a complex sequence of motion
