Michael Jackson has passed away.

[The Stryker]

We've just learned Michael Jackson was taken by ambulance to a hospital in Los Angeles ... and we're told it was cardiac arrest and that paramedics administered CPR in the ambulance.

He was picked up at his home around 20 minutes ago -- we're told his mother is on the way to visit him.

UPDATE: The 911 call came in at 12:21PM at his Holmby Hills home in L.A.
