Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...
Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never ...
When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawai'i at Mānoa researcher has discovered ...
Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA's Chandra X-ray Observatory and other telescopes displays a collection of galactic ...
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun's history may have helped create Earth's unique climate and driven ...
Our everyday life is flooded with photons, the quantum building blocks of light. For cutting-edge technology, from quantum computing to deep-tissue imaging, detecting every single photon counts.
On Aug. 15, the CTAO LST Collaboration and the MAGIC Collaboration released findings from observations of OP 313, the most distant very-high-energy blazar ever recorded. The paper, published in Astronomy & Astrophysics, presents ...
At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a ...
