Mercury’s perplexing orbit led to the prediction of a new inner planet, Vulcan. Einstein’s general relativity removed the need for such a body, but today’s paper pursues a wild idea – does Vulcan exist as a primordial black hole?
There are numerous candidates for dark matter, including primordial black holes. Today’s paper addresses whether an upcoming NASA space telescope could detect these exotic black holes from the early universe.
Stars like the Sun will eventually become white dwarfs, and some planets might hang on through the process. Today’s paper investigates whether such planets could hold onto their water.
We have not found a Solar System analog, but upcoming missions stand to discover more and more multi-planet systems. We can begin to understand these systems by asking: what would our own Solar System look like to distant observers?
During a phase of planet formation, planetary embryos interact, collide, and/or combine to form the surviving planets we know and love. Simulating this phase is computationally challenging, but could machine learning help out?
