With the help of the James Webb Space Telescope, astronomers have discovered a galaxy that violates the basic concepts of the ...

Dark matter remains one of the most intriguing components of the cosmos, making up about 27% of the universe's total mass-energy content. It cannot be seen directly, yet its presence is inferred ...

Astronomers using the James Webb Space Telescope have discovered a massive galaxy from the early universe, XMM-VID1-2075, that shows no signs of rotation. Such 'slow rotator' galaxies are usually seen ...

Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center -- a surprise suggesting our galaxy's gravitational core may have less dark matter than ...

Galactic astronomy is the study of the structure, composition and evolution of our own Milky Way and its constituent stars, gas and dark matter. It encompasses the mapping of stellar populations—disc, ...
