There's a killer lurking in our galaxy, a star ready to explode into a supernova. Seen from Earth, a supernova in the Milky Wave would have a terrible beauty. But for us, it could be fatal. In a few seconds, it can release as much energy as the sun will over its entire lifetime. It could be anywhere. It is nearly impossible to predict where and when the next supernova will happen. The hunt is on to find the next supernova before it finds us.

Described as one of the most influential female boxers of all time, helping legitimize women’s participation in the sport, Christy Martin shocked the world by becoming a superstar after winning a blood-soaked undercard match at the Mike Tyson/Frank Bruno fight in 1996.

Our world, our solar system, our universe, none of it would exist without a ghostly particle called the neutrino. They are our early warning system whenever there's trouble in the universe. Neutrinos trigger star-killing explosions, supernovas. Neutrinos can answer so many questions, from why do we exist to how was the universe created. Neutrinos can be the very reason that we exist at all. The more we understand these elusive particles, the more we can gain insight into how the universe works.

Supermassive black holes are the engines that power our universe and one of the major players in the evolution of galaxies. They're in fact the driving force at the heart of nearly every galaxy in the cosmos. Now, a new mystery has emerged about the oldest supermassive black holes. We see supermassive black holes in the very early universe. And we don't understand how they grew so large so quickly. We have clues about their formation but, can we solve the mystery of this supermassive growth spurt?

A new video pushes panic go to the next level, galvanizing the 'internet nerds' to intensify their own painstaking investigation as police join the hunt. In the previous videos, the object on the bed were cats, in this video, it was an actual person. How hard is it going to be to track him down? How dangerous is this man?

In astronomy, we've been looking at different kinds of light and opening up the universe a little bit more of the time. But then in 2015, the roof came off. Something happened that changed everything, the ability to see waves in space and time itself. Gravitational waves help us roll back the clock to the dawn of time, discover epic cosmic collisions, on make Earth-shaking discoveries. Gravitational waves are the biggest game changer since the invention of the telescope. We have a completely new universe to view now. A new exploration of space is just beginning.
