A “dark object” detected as an anomalous notch in the arc of a gravitationally warped section of space, could be the smallest clump of pure dark matter yet found. If so, it would further validate the concept of cold dark matter and will help constrain the properties of dark matter particles as physicists and astronomers continue to hunt for what …

Astronomers say NASA’s James Webb Space Telescope may have spotted the universe’s first “dark stars,” primordial bodies of hydrogen and helium that bear almost no resemblance to the nuclear fusion-powered stars we’ve come to know. As detailed in a recent paper published in the journal Proceedings of the National Academy of Sciences, the team suggests that the very early days …

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is unlikely to occur. The universe will ultimately cease to expand and collapse in a fiery collapse called the “Big Crunch,” say physicists Hoang Nhan Luu, Yu-Cheng Qiu, and …

For more than thirty years, cosmologists have operated under the assumption that about 95% of the universe is composed of two mysterious entities: dark matter, which exerts gravitational pull without emitting light, and dark energy, which appears to accelerate the universe’s expansion. These ideas became key pillars of the standard cosmological model, guiding both theoretical development and large-scale experimental searches. …

The gravitational lensing not only splits the light source, but magnifies it, allowing a detailed view of the light source behind the lens. Thanks to this, the team says that HerS-3 appears to be a bright starburst galaxy—a galaxy undergoing explosive star formation—and was formed at a time when star formation was at its peak throughout the universe. HerS-3 also …

The breakthrough scientific moment for fusion power—and the potential for nearly limitless electricity from a so-called star in a jar—came at the end of 2022 when scientists at Lawrence Livermore National Laboratory successfully achieved “first ignition,” fusing atoms through extreme heat to generate more energy than the setup consumes for the first time ever. The project’s principal designer, nuclear physicist …

Israeli scientists unveil bold method to detect dark matter | The Jerusalem Post Jerusalem Post/Science Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes. This is an artist’s impression of a runaway supermassive black hole that was ejected from its host galaxy as a result of a tussle between …
