"WE ARE DEAD STARS…looking back up at the sky. Everything you are, literally the iron in your blood, comes from the instant before a star dies. In the case of the most massive stars, the core of the star collapses and sets off the most violent, brilliant reaction we know of called a supernova reaction. Everything outside the element iron, everything heavier, all the gold, all the silver, all the lead, all the uranium - that’s formed in that supernova explosion. A single star will glow as brightly as an entire galaxy, as hundreds of billions of stars, in that moment of death and and that’s what you are. That is literally what your body is, that instant of death.

Voyager 1 has officially left the solar system
It may have taken 36 years of coasting through space, but the Voyager 1 spacecraft has entered interstellar space, becoming the first man-made probe to reach that far-off realm.
The scientific community has been debating whether Voyager had already left for some time now, but it wasn’t until today that NASA was confident enough to made the estimate official.

Lead author Don Gurnett, an Iowa State plasma physicist and a Voyager project scientist, said the data showed conclusively that Voyager 1 had exited the heliopause — the bubble of hot, energetic particles that surrounds our sun and planets — and entered into a region of cold, dark space called the interstellar medium.
