Across the universe, dark matter annihilation may heat up dying stars
Scientists speculate that some dead stars made of the densest matter in the known universe, so-called “neutron stars,” may act as traps for dark matter particles that collide and annihilate …
Neutron stars may heat up due to annihilation of dark matter
Image source: Pixabay/CC0 Public Domain One of the big mysteries about dark matter particles is whether they interact with each other. We still don’t know the exact nature of dark …
What is the most efficient way to explore our nearest stars?
In 1903, the Wright brothers achieved the first successful self-propelled flight. They have gone down in history, laying the foundation for transatlantic flight, supersonic flight and even the exploration of …
Researchers propose new formation model for massive hot subdwarf stars
Construct the evolution model of SMSS J1920. The initial progenitor cell mass is 1.8 M where Z = 0.001. The resulting sdO/B has a mass of 0.553 Mthe envelope quality …
There may be millions of invisible ‘mirror stars’ in the Milky Way, and astronomers know how to find them
There may be an invisible universe of stars, nebulae, and galaxies made entirely of dark matter. Astronomers now know how to look for it. In short, dark matter is a …
Ancient stars could create elements with more than 260 protons
R-process nucleosynthesis.Image credit: Lawrence Livermore National Laboratory The universe’s first stars were terrifying beasts. Composed only of hydrogen and helium, they may be 300 times more massive than the Sun. …
New research suggests atomic-sized black holes could eat stars from the inside out
New research theorizes that a handful of primordial black holes that zipped through the universe shortly after the Big Bang may have been captured by stars, and that these ancient …
