In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the University of Queensland have provided insights into the likely fate of our galaxy, the Milky Way. This study, led by Dr. Sarah Sweet and part of the larger Delegate survey, investigates the future merger between the Milky Way and the Andromeda Galaxy, along with …

A recent discovery sheds light on a bizarre phenomenon at the center of our Milky Way: the detection of cold hydrogen clouds embedded within the superheated Fermi bubbles, vast structures of gas and cosmic rays that have been towering over the galactic center for millions of years. The unexpected nature of these clouds suggests a much more recent and violent …

Astronomers have identified a vast, previously unknown structure in our galaxy that could change how scientists understand star formation and the flow of matter in the Milky Way. Known as the Midpoint cloud, this enormous giant molecular cloud spans roughly 200 light-years, or about 650 trillion miles, and appears to serve as a major conduit feeding material from the galaxy’s …

Head away from city lights in late July to see the dense core of the Milky Way arcing towards the southwestern horizon against a blissfully dark sky as the waning lunar disk approaches its new moon phase. Our solar system orbits within a 100,000-light-year-wide spiral galaxy known as the Milky Way. On clear nights under dark skies, we can see …

In the center of our galaxy, gigantic, balloon-like structures of high-energy radiation extend thousands of light-years above and below the Milky Way’s plane. Known as the Fermi bubbles, the massive lobes may have been the result of a violent outburst in our galaxy’s recent past. A new discovery of cold hydrogen clouds embedded inside the bubbles adds another level of …

In April, when Yellowstone National Park geologists made their first visit this year to the Norris Geyser Basin, they encountered a new feature they hadn’t seen before. They were checking the area’s temperature logging stations, a routine maintenance job – but since their last visit, something was different. Where previously there had been a rather featureless patch of ground at …

Our cosmic neighborhood may be far more crowded than previous estimates have suggested. New research hints the Milky Way could have many more small dwarf galaxy “satellites” around it than expected. The team, comprised of cosmologists from Durham University, combined supercomputer simulations with mathematical modeling to predict the existence of missing Milky Way “orphan” galaxies. The researchers’ novel technique suggests …

The Milky Way may be surrounded by dozens of yet-to-be-detected satellite galaxies, scientists claim. Using the highest-resolution simulation of our galaxy’s dark matter — an invisible entity that shapes the large-scale structure of the universe — and new mathematical models, cosmologists predict that more than 100 additional satellite galaxies beyond the ones already cataloged may be swirling around our own. …

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with …
