Cosmic Cannon: How an Exploding Star Could Fry Earth

Cosmic Cannon: How an Exploding Star Could Fry Earth: "Shooting out jets of energy or blobs of stuff the size of Earth at nearly light-speed, exploding stars called supernovae may hold more potential peril than anyone had ever imagined, according to a growing suspicion among some researchers.

While scientists have long tried to link supernovae to mass extinctions on Earth, there is no solid evidence. But recent observations of high-energy emissions in space have some scientists suggesting that our planet may in fact get fried every now and then."

Curious, end-of-the-known universe scenarios.
