Spaghettified

 

There may be many ways to end one's existence, but death by spaghetti may not be the most attractive.

Actually, I mean death by spaghettification.  And unless you eat really, really way too much pasta, you're probably safe.

But stars that wander too close to a black hole aren't safe.  For the process of spaghettification describes how a star gets destroyed by the massive gravity of a black hole.

And this has just been observed, and set a record for being the closest to Earth that it has ever been observed.

Witness The Very Last Scream of Light From a Star Devoured by a Black Hole

"Although catching a stellar death-by-black-hole is uncommon, astronomers have observed enough by now to figure out the broad strokes of how it happens. When a star ventures too close, the immense tidal force of the black hole - the product of its gravitational field - first stretches and then pulls the star so hard that it's torn apart. 

 This tidal disruption event (TDE) releases a brilliant flare of light before the debris of the disintegrated star disappears beyond the black hole's event horizon. But that flare of light is often at least partially obscured by a cloud of dust, which makes studying the finer details difficult. 

 The new TDE, first spotted in September of last year [warning:  highly technical!] and named AT2019qiz, is now helping a team led by astronomer Matt Nicholl of the University of Birmingham in the UK shed light on the origin of this dust."
