New Planets
Astronomers have been busy finding old and Earth-like planets. The first is a gaseous giant, double the size of Jupiter, which is about 13 billion years old. Circling a pulsar and a white dwarf 5,600 light years away in Scorpio, this planet is the oldest object Earth astronomers have been able to spot. Closer to home, in HD70642 (in Puppis, a constellation that makes up the stern of the Argo Navis, the ship used by the Argonauts) there is another gas giant (because, you know, they are the easiest to spot). This Jupiter-like planet is in approximately the same celestial position as our own gas giant, leading scientists to consider the certain possibility of denser planets on closer orbits. The system is 90 light years away which, at our current level of technology, would take us about a half million years to reach. So until we get better telescopes or discover a FTL drive, we're just guessing.
