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 night sky. 09/03/15 Watch as the colour of the sky changes due to the rising Moon. This was a 4 hour time lapse recorded last night from 21:00-01:00.
Hello! I'm a person, and I find physics (specifically astrophysics) to be incredibly interesting, and I'd like to know more about it. Have any idea on what I should read/watch to get more educated on the subject? I don't know where to start ^^".
Well I get a lot of my updates in the science world from here, http://www.sciencedaily.com/news/space_time/astrophysics/ just look under the astrophysics section then when you get to understand some of the key concepts the look up papers on science direct and google scholar for the best free papers :)
The Laniakea Supercluster (Laniakea; also called Local Supercluster or Local SCl) is the galaxy supercluster that is home to the Milky Way, our galaxy, and therefore to the Solar System and the Earth.

Take a look around Mars. Here’s where I’m working right now.

For thousands of years, sea level has remained relatively stable. But now, Earth’s seas are rising. Since the beginning of the 20th century, they have risen about eight inches, and more than two inches in the last 20 years alone!
As water warms, it expands and takes up more space. That means that when oceans warm, the sea level rises. This summer, we’ve been researching exactly how global warming has impacted Greenland’s ice sheet. Our ICESat-2 mission will use a laser to measure the height of the planet’s surface. Over time, we will be able to provide a record of elevation change, and estimate how much water has melted into the ocean from land ice change.
So how much ice are we actually losing? Great question, but the answer might shock you. In Greenland alone, 303 gigatons of ice was lost in 2014!
Since we know that ice is melting, we’re working to gain a better understanding of how much and how fast. We’re using everything from planes, probes and boats, to satellites and lasers to determine the impact of global warming on the Earth’s ice.

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.
