Astronomers and the public alike are delighting in the glittering depths of the universe revealed by the James Webb Space Telescope

Date Time A Warp in Milky Way Linked to Galactic Collision When most of us picture the shape of the Milky Way, the galaxy that contains our own sun and hundreds of billions of other stars, we think of a central mass surrounded by a flat disc of stars that spiral around it. However, astronomers know that rather than being symmetrical, the disc structure is warped, more like the brim of a fedora, and that the warped edges are constantly moving around the outer rim of the galaxy. “If you have ever seen the audience making a wave in a stadium, it’s very similar to that concept,” said Xinlun...

This is because we are stuck looking at the Milky Way from the perspective of Earth, whereas astronomers can see the warp of distant galaxies. Now, astronomers at the Sloan Digital Sky Survey have come up with a novel way of examining the warp of the Milky Way. The researchers studied the positions and motions of stars all across the Milky Way. Over 10 years, astronomers examined the movement of stars using the Apache Point Observatory Galactic Evolution Experiment (APOGEE), which collects data on spectra - measurements of starlight split into its component wavelengths. Milky Way is performin...
