   HUBBLE HELPS CONFIRM OLDEST KNOWN PLANET   
      
   NASA's Hubble Space Telescope precisely measured the mass of the oldest   
   known planet in our Milky Way galaxy. At an estimated age of 13 billion   
   years, the planet is more than twice as old as Earth's 4.5 billion   
   years. It's about as old as a planet can be. It formed around a young,   
   sun-like star barely 1 billion years after our universe's birth in the   
   Big Bang. The ancient planet has had a remarkable history because it   
   resides in an unlikely, rough neighborhood. It orbits a peculiar pair of   
   burned-out stars in the crowded core of a cluster of more than 100,000   
   stars. The new Hubble findings close a decade of speculation and debate   
   about the identity of this ancient world. Until Hubble's measurement,   
   astronomers had debated the identity of this object. Was it a planet or   
   a brown dwarf? Hubble's analysis shows that the object is 2.5 times the   
   mass of Jupiter, confirming that it is a planet. Its very existence   
   provides tantalizing evidence that the first planets formed rapidly,   
   within a billion years of the Big Bang, leading astronomers to conclude   
   that planets may be very abundant in our galaxy.
