Researchers find the source of gamma rays in a small neighboring galaxy

According to a recent study published in Nature Astronomy, an international team of researchers has discovered a small satellite galaxy of the Milky Way filled with dark matter. However, the emissions are more likely the result of millisecond pulsars blasting out cosmic particles. The magenta...

Researchers have created ‘Time machine’ simulations to study the lifecycle of ancestor galaxy clusters

According to a new study published in Nature Astronomy, researchers have constructed models that directly recreate the whole life cycle of some of the largest groupings of galaxies recorded in the distant universe 11 billion years ago. Cosmological simulations are important for figuring out...

Astronomers find large group of rogue planets

Rogue planets are elusive cosmic objects that have similar masses like the planets in our Solar System. But they do not orbit a star. They roam freely on their own. A team of astronomers have used the data from several European Southern Observatory telescopes...
