With one of the world’s most powerful telescopes, an international team of astrophysicists including Stony Brook University’s Neelima Sehgal mapped dark matter in our Universe to a level not done before.

The whitish band shows where dust in our own Milky Way galaxy emits contaminating light, preventing a deeper view.
