How Do You Date a Star?
Figuring out the age of a blinking speck in the sky is a difficult feat, especially if considering how many types of stars there are. This is where a Hertzsprung-Russell meets a gyrochronologist.

What’s On The Other Side Of A Black Hole?
Normal maps are useless inside black holes. At the event horizon - the ultimate point of no return as you approach a black hole - time and space themselves change their character. We need new coordinate systems to trace paths into the...

This Diagram of Earth Is a Lie
When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

White Holes
Lurking in the depths of the mathematics of Einstein's general relativity is an object even stranger than the mysterious black hole. In fact it's the black hole's mirror twin, the white hole. Some even think that these could be the...
