The solar gravitational lens could map white dwarfs and black holes

It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev's astounding productivity in pumping out academic articles, but partly because such a groundbreaking mission has lots of positive aspects—as well as challenges that need to be addressed. A new paper, posted to the arXiv preprint server from Dr. Turyshev, stresses an often overlooked feature of the SGL: how useful it can be for imaging things other than faraway exoplanets.
