The more developed a galaxy is, the more chaotic the orbits of its many stars are, according to new research that answers an important detail about how galaxies age. Our sun revolves around the center of the galaxy once every 225 million years, at an average speed of 514,495 mph (828,000 km per hour). Astronomers… Read More »
A neutron star is the remains of a massive star that once died during a supernova explosion. Overall, neutron stars are considered some of the most extreme objects in the known universe – and that’s especially true when these incredibly dense stellar remnants sit next to companion stars (that haven’t yet ‘died’) close enough to… Read More »
NASAs James Webb Space Telescope (JWST) is known for capturing our universe with unprecedented precision and sensitivity. The images are not only scientifically useful, but also beautiful. From the blue and gold of the Southern Ring Nebula to the pink, orange and purple of Cassiopeia AJWST images depict the universe in brilliant colors. The images… Read More »
“Which came first: the galaxy or its monstrous black hole?” Technically, it’s an even older riddle than the chicken or the egg, even though we only became aware of it relatively recently. And according to new research, scientists may finally have an answer. It has long been believed that supermassive black holes that existed close… Read More »

Scientists may have finally solved the mystery of cosmic ORCs, or “strange radio circles” as they are officially called, which are so large they are ten times as wide as the Milky Way and can encompass entire galaxies. A team of astronomers led by Alison Coil, a professor of astronomy and astrophysics at the University… Read More »
