The subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth—it sits at a distance of around 44 million light-years from us, placing it within the Milky Way's ...
Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis.
A team from the University of Kentucky's Department of Physics and Astronomy has observed evidence of ancient impacts that are thought to have shaped and structured our Milky Way galaxy.
A group of astronomers have shown that the fastest-moving stars in our galaxy - which are travelling so fast that they can escape the Milky Way - are in fact runaways from a much smaller galaxy in orbit around our own.
A primitive galaxy that could provide clues about the early universe has been spotted by astronomers as it begins to be consumed by a gigantic neighboring galaxy.
A team of international astrophysicists led by The Australian National University (ANU) has shown how most of the antimatter in the Milky Way forms.
Research conducted by scientists at Rochester Institute of Technology rules out a challenge to the accepted standard model of the universe and theory of how galaxies form by shedding new light on a problematic structure.
A supermassive black hole inside a tiny galaxy is challenging scientists' ideas about what happens when two galaxies become one.
