There are parts of the universe that are extremely hard to see, even for our most advanced telescopes. Gas and dust don’t emit any light, and are only visible by the light that they happen to block from stars and galaxies. Magnetic fields are even harder since regular light typically passes right through them. However, according to a new paper available in pre-print on arXiv, by Manisha Caleb of the University of Sydney and their co-authors, we’re currently commissioning a potentially game-changing new tool that could use a particularly violent astronomical phenomenon to provide new insight into these hard to see places.
