Our universe is a chaotic sea of ripples in space-time called gravitational waves. Astronomers think waves from orbiting pairs of supermassive black holes in distant galaxies are light-years long and have been trying to observe them for decades, and now they're one step closer thanks to NASA's Fermi Gamma-ray Space…

HD1, object in red, appears at the center of a zoom-in image. Credit: Harikane et al. Shining only ~300 million years after the Big Bang, it may be home to the oldest stars in the universe, or a supermassive black hole. A group of astronomers from across the world, including…

Home News Science & Astronomy Christine Ye presenting her research on gravitational waves. (Image credit: Society for Science) Around the world, astrophysicists are poring over the blips of gravitational waves that ripple through Earth when distant black holes or neutron stars collide. One of those astrophysicists is Christine Ye, a…

What lurks at the Milky Way’s heart? Astronomers have known most of the answer for decades. Just as in most large galaxies, a supermassive black hole sits at the core of our own island in the universe, enveloped in a swirling maelstrom of molecular clouds and stars. But something seems…

Last year, a team from The Ohio State University discovered an object that was said to be one of the smallest black holes ever seen, and also the one closest to Earth at just 1,500 light-years away. It was followed by the discovery of another object some 12,000 light-years away…

A new study examined the effects of the supermassive black hole at our galaxy’s center on the atmosphere of planets in the Milky Way. To determine, scientists mainly focused on two fundamental mechanisms: 1. How can black hole winds heat atmospheres and drive atmospheric escape? 2. How can they stimulate…

Overall there is a gap of US$106 billion in available investment in agricultural small- and medium-sized enterprises (agri-SME) ranging from…

NASA’s Chandra X-ray observatory revealed that the objects within the “Spiderweb” protocluster are feasting and growing. After observing the Protocluster over eight days with Chandra, scientists detected signs of 14 actively growing supermassive black holes. Located about 10.6 billion light-years from Earth, the Spiderweb galaxy is at the center of…
