When you read a scientific story in a popular blog or magazine, many times you will see the caveat "artist interpretation" next to some of the accompanying images. This as a gross undersell of the time, effort, and most important, accuracy, that goes into developing the renders. While we don't know what a black hole or an exoplanet looks like, it is important to attempt to visualize them, and to do it as accurately as possible.

Astronomers from Keele University, the Max Planck Institute for Astronomy, and others, have discovered the first atmosphere around an Earth-sized planet. The planet, GJ1132b is about 1.4x Earth's diameter and 39 light years away from us. Currently there are over 3000 known planets orbiting stars other than the Sun, but only a handful of which have been confirmed to have atmospheres, and all of which are massive Jupiter-sized planets. In the ongoing quest to find a planet similar to Earth, this
