The Milky Way's Turbulence Distorts Light from Distant Quasars
We may be getting better images of the Milky Way's supermassive black hole in the future. Astronomers used 10 years of observations of a distant blazar to detect turbulence in the Milky Way's interstellar medium. This turbulence makes images of Sagittarius A-star blurry.

New Algorithm Cracks the Asteroid Routing Problem
The Traveling Salesman is a classic problem in mathematics that requires a solution to the most efficient path to take to visit a given number of cities in the least amount of time. But scale this relatively simple concept up to space travel and the calculation becomes much more complex. Instead of visiting a stationary spot on Earth, when calculating the most efficient path to visit asteroids you must account for the fact they are traveling tens of thousands of miles an hour, and their exact position will change based on when a spacecraft leaves. This is known as the Asteroid Routing Problem, and a new paper from a group of Canadian and European researchers lays out a framework that can find the exact solution to any particular combination of asteroids to be visited.

What If the Universe Had No Beginning? Part 2: No Boundary, No Problem
Hawking faced a question with no answer hiding behind it. The best boundary condition for the universe, he decided, was that there was no boundary at all. To make that statement into physics, he had to do something deeply strange to time.
