Hey has there been any discussion about this object
here before? It's about a planet orbiting a pulsar and a
white dwarf inside a globular cluster. I know the story
is a little old, but I found it fascinating. A planet that'
s 12.7 billion years old! Just a billion years after the
Universe was banged out. The planet is in the pulsar
system PSR B1620-26 in the globular cluster M4.

.... a bit more current stuff.

The CMBR back then was really hot, so it might have done something
interesting a few billion years after formation.
