About
Scientists analyzing nearly 400,000 galaxies with the Euclid space telescope have uncovered new clues about why spiral galaxies maintain their iconic shapes.
The findings support the density wave theory, revealing that spiral arms behave like cosmic traffic jams rather than permanent structures. Researchers also discovered that a galaxy's spiral arm count is closely linked to its central mass, star formation, and the distribution of dark matter, providing a powerful new window into how galaxies evolve.
