Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It is the […]

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They believe this invisible substance—which […]

A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it’s still going strong, new research led by a University of Oregon […]

Aging stars can completely destroy their planets. When a star reaches the end of its life on the main sequence, it goes through dramatic changes. And those changes don’t just dictate the star’s fate; they […]

Quasi-periodic oscillations (QPOs) are a rare phenomenon in active galactic nuclei. They have been observed to occur at periods ranging from minutes to hours, days, weeks, and even years across the electromagnetic spectrum. A new […]

Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent supernova explosions. Through a combination of observations and stellar […]

Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new massive and quiescent red galaxy, which they dubbed “Red Potato.” The discovery was reported in a research paper published […]

Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we’ve lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists […]

Where starlight doesn’t reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation shows how charged high-energy […]

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe […]
