Astronomers have discovered two new satellite galaxies of the Milky Way, and the findings could help us better understand dark matter. Dark matter is the mysterious substance that makes up about 85% of the matter in the universe but is effectively invisible to us. The discoveries also bring scientists one step closer to solving an… Read More »
New findings from the Gaia space telescope suggest that, cosmically speaking, the Milky Way may have destroyed a small galaxy a long time ago. In fact, it looks like the last major collision between our galaxy and another has occurred billions years later than previously suspected. It has long been known that the Milky Way… Read More »

Astronomers have discovered three “runaway” ancient stars on the outskirts of the Milky Way galaxy, racing in the wrong direction at speeds of hundreds of thousands of kilometers per hour. Although alive for their age, the three stars are so old that they date back to the formation of the first galaxies. This is one… Read More »
What did our ancestors think when they looked at the night sky? All cultures have assigned special meaning to the Sun and Moon, but what about the pearly band of light and shadow we call the Milky Way? My latest research has shown an intriguing connection between the Egyptian goddess and the Milky Way. Scholars… Read More »
The Gaia space telescope is revealing the history of the Milky Way by tracking the movements of billions of stars in our galaxy – and the spacecraft’s latest findings reveal this story more truly than ever before. Gaia has discovered two streams of ancient stars that appear to have come together 12 billion years ago,… Read More »
The Milky Way is our galaxy, but how well do we really know it? A team led by Villanova University researchers as part of a NASA-funded project has obtained a never-before-seen image of the central engine at the heart of our galaxy. A new map of this central region of the Milky Way, which took… Read More »
Although our telescopes have actually caught some Stunning images of the Milky Way, astronomers have only a vague understanding of our home galaxy. It took a lot of work to even get this outline, and it’s incredible what we were able to learn from our limited perspective. Here on the Earth’s surface Milky Way galaxy… Read More »
A treasure trove of molecules has emerged in two galaxies that we see as they existed 12 billion years ago, revealing information about how ancient universes formed stars. APM 08279+5255, one of the distant galaxies quasar – active supermassive black hole The other galaxy, NCv1.143, is a more “normal” galaxy, with large amounts of gas… Read More »
A river of hydrogen gas flows outward from the Large and Small Magellanic Clouds, two dwarf galaxies located on the outskirts of the Milky Way. The contents of this river, called the Magellanic Stream, have puzzled astronomers for decades. But now, for the first time, a team of researchers has been able to locate stars… Read More »
