Gravitational waves are ripples in spacetime created when pairs of black holes spiral into each other and eventually merge. But if this ripple has been warped by another massive object on its way to Earth, a new analysis ...
Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to NGC 7253—a pair of spiral galaxies caught in each other's gravity. Captured by the Gemini North telescope on Maunakea in Hawai'i, the image created a spectacular ...
Astronomers have discovered a second interstellar cloud near the center of the Milky Way that is extraordinarily rich in complex molecules, including several molecules associated with prebiotic chemistry. The newly studied ...
Every second, tens of billions of neutrinos produced by nuclear fusion in the sun pass through every square centimeter of Earth—and through our bodies—almost without interacting. Although they are among the most abundant ...
Astronomers from the University of Manchester and the University of the Western Cape have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, opening a powerful new way to map ...
By combining roughly two decades of observations from NASA's Swift X-ray Telescope with radio monitoring, astronomers have caught a supermassive black hole at the heart of the Perseus Cluster suddenly flaring in X-rays, and ...
The universe has been having fewer and fewer stellar "babies." Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for ...
One of the central ideas in modern physics is the phase transition—a sudden transformation of the state of a material. We encounter phase transitions throughout everyday life: water freezes into ice, wax melts in the warmth ...
After analyzing infrared images captured by the James Webb Space Telescope (JWST), an international team of researchers has discovered multiple massive black holes from approximately 12.5–12.8 billion years ago that were ...
Earlier this summer, the four of us spent three days in a room with a dozen others whose jobs sound nothing like ours, or like each other's: a cosmologist, an emergency management scholar, a genetic counselor, a hydrologist, ...
