Big math news! It’s been thirty years since mathematicians last found a convex pentagon that could “tile the plane.” The latest discovery (by Jennifer McLoud-Mann, Casey Mann, and David Von Derau) was published earlier this month. Full story.
To visualise the black hole in Interstellar, the VFX team collaborated with theoretical physicist Kip Thorne to solve the equations for propagation of light around a spinning black hole. The shape is due to way light is lensed (deflected) by the strong gravitational field of the black hole. The asymmetry is caused by the relativistic time dilation near the event horizon.
The top image shows the black hole in the movie. The bottom image is a more accurate visualisation taking into account Doppler and gravitational frequency shifts. This was considered too confusing for the audience. They also slowed the black hole’s spin down from that required to explain the time dilation experienced in the movie, to make the black hole appear less asymmetric.
The are releasing two papers on their work, the first of which is available in preprint on arXiv.

The interstellar medium is the gas and dust between stars. Of its mass, this gas is composed of mainly hydrogen and helium with a touch of heavier elements. Highly dense regions of the ISM known as molecular clouds are directly responsible for the formation of stars.

I love space. I've been to space camp in Huntsville Alabama and I am planning on going every summer. I look forward to be an astronaut for nasa on the sls that is planned to be launched 2018. And the manned mission 2030. So yeah I won't let anything get in my way.
