Stacking the spectra of 324 pairs of radio galaxies and background quasars, a team led from Arizona State University has ...

The Milky Way, our galaxy, has not always looked the way it does today. We see it as a band of stars across the sky, but from an external point of view, it would be a spiral galaxy with four arms and ...

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its ...

Sci-fi tends to paint the edge of our galaxy as a desolate backwater, but in one early galaxy, the galactic rim is the bright, bustling center of activity, and the core is the aging backwater. The ...

In a feat of galactic archeology, astronomers are using ever more detailed information to trace the origin of our galaxy—and to learn about how other galaxies formed in the early stages of the ...

Scientists are turning to the beautiful and famous Whirlpool Galaxy to look for areas where stars could eventually be born. By mapping out the presence of particular chemicals, they hope to learn ...

A region of glowing gas in the Sagittarius arm of the Milky Way galaxy, NGC 3576 is located about 9,000 light years from Earth. Such nebulas present a tableau of the drama of the evolution of massive ...

Galaxy formation and evolution modelling combines astrophysical theory, numerical techniques and observational data to reconstruct the life cycle of galaxies from the early universe to the present day ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...
