In a world's first, scientists have observed a star completely swallowing up a planet, a phenomenon that will also happen to our own sun one day, killing us all.

Astronomers have, for the first time, witnessed a star, not unlike our sun, completely guzzling up a gas giant about the size of Jupiter, according to the AP. This will happen to the Earth, too, when our own sun eventually becomes a red giant and wipes out our planet. The good news, though, is that this shouldn't happen for another 5 billion years, co-author Morgan MacLeod said.

Anyone alive today won't have to suffer this fate, thankfully, and it's an open question whether or not humanity will be around in 5 billion years anyway. But whatever is left of our Earth in 5 billion years will be gobbled up and destroyed in spectacular fashion.
