Stars and galaxies make up much of the universe’s ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.This post was originally published on this site

A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by University of Tsukuba, could uncover between 1 and 10 million dusty star-forming galaxies throughout cosmic history.This post was […]

The first-ever image of a black hole—a glowing, ring-like structure at the heart of galaxy M87—was unveiled to the world in a landmark moment in 2019. Now, researchers have taken the next big step—moving beyond […]

The Milky Way may have undergone a dramatic change in orientation during its history, according to new research that helps explain a long-standing mystery about our galaxy. Using supercomputer simulations of galaxies like the Milky […]

Although general relativity (GR) is an elegant theory of gravity, we don’t often need to use it. For most gravitational interactions, Newton’s theory of universal gravitation works just fine. Newton’s model is good enough to […]

For the third time in 35 years, the black hole at the center of the galaxy IC 3599 has erupted, and this time, astronomers were watching it closely. IC 3599, a galaxy roughly 280 million […]

A new study led by astronomers at The University of Texas at Austin proposes a theory that could solve two astronomical riddles at once: the nature of Little Red Dots and the origin of globular […]

For more than a century, astronomers have puzzled over a strange discrepancy in the historical record. Theta Eridani, a modest star in the constellation Eridanus, is the third-brightest star in its constellation, with a magnitude […]

An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint server arXiv, deliver important insights into […]
