Doing a deep dive into the dusty Milky Way

An animated journey through the dusty Milky Way reveals the outlines of our galaxy taking shape as we look outward from Earth. Astronomers have created an animation to model dust in the Milky Way using new data from an interactive tool that uses data from...

Star with the shortest orbital period around black hole discovered

The fastest known star, discovered by researchers at the University of Cologne and Masaryk University in Brno (Czech Republic), travels around a black hole in record time. S4716 orbits Sagittarius A*, the black hole at the centre of our Milky Way, in four years...

The formation and evolution of massive binaries may share the same mechanism in Milky Way and Andromeda galaxies

A research team led by Prof. Qian Shengbang and Ph.D. student Li Fuxing from the Chinese Academy of Sciences' Yunnan Observatories discovered that the formation and evolution of massive binaries in the Milky Way and the Andromeda Galaxy (M31) may share the same mechanism....

Astronomers discover how galaxies form through mergers

Astronomers in the United Kingdom announced today that they have discovered how galaxies like our own Milky Way formed over 10 billion years of cosmic time by colliding with an abundance of separate galaxies. Galaxies are the universe's largest single objects, and the origin...

Researchers find 12 semidetached mass-transfer massive binaries in galaxy M31

PhD student Li Fuxing, Prof. Qian Shengbang and some researchers from Yunnan Observatories of the Chinese Academy of Sciences have discovered 12 semidetached mass-transfer massive binaries from a total of 437 eclipsing binaries in Andromeda galaxy (M31). The secondary (less massive) components filled their...

Hubble spies a serpentine spiral

The slowly winding spiral arms of the galaxy NGC 5921 snake across this image from the NASA/ESA Hubble Space Telescope. This galaxy is situated approximately 80 million light-years from Earth. It is much like our own galaxy which is the Milky Way and contains...
