It is up to 400 light-years deep and 9,000 light-years long, undulating nearly a tenth of the way across the Milky Way's diameter. At its closest to us, the wave is just 500 light-years away.

Languages; English. An enormous wave has been discovered in the Milky Way that may have formed as a result of a collision with a massive mystery object—potentially a clump of dark matter ...

Spanning about 9,000 light-years (or about 9% of the galaxy's diameter), the unbroken wave of stars begins near Orion in a trough about 500 light-years below the Milky Way's disk. The wave swoops ...

NASA/CXC/SAO/E.Bulbul, et al. and NASA's Goddard Space Flight Center/Stephen Walker et al. An international team of astronomers has discovered a vast wave of hot gas twice the size of the Milky Way.

A new map reveals the outskirts of the Milky Way galaxy, including a wave of stars disturbed by a small galaxy on a collision course with our own. Data collected from the European Space Agency’s ...

Through a process that the researchers equated to "galactic seismology," the team modeled a wave pattern that could explain the strange ripple effect setting the Milky Way's stars off-kilter.

This wave is about twice the size of our Milky Way Galaxy and scientists think they know what caused it. Billions of years ago a small galaxy cluster must have grazed Perseus causing the massive ...

This illustration shows data from the Radcliffe Wave, indicated in red, superimposed on an artist's rendering of the Milky Way galaxy. Scientists reported that this massive structure of star ...

A simulated map of the Milky Way as it would appear in gravitational waves has given a powerful impression of what future space-based detectors will observe. Over 90 gravitational-wave events have ...
