The constellation Lyra was named after the haunting lyre of Orpheus. After the great musician was killed by maenads, his severed head and his lyre were thrown into the river and then drifted down to the sea. Zeus sent his eagle to pick up the lyre and carry it up into the night sky as an eternal reminder for human creative professionals about the nature of their discipline. The myth of this constellation is entirely different in China—as we have seen—yet it too revolves around star-crossed lovers sundered by circumstance.
Meanwhile…the robot observatory Kepler has been scanning the heavens for the subtle signs of exoplanets since 2009. The spacecraft malfunctioned in 2013, and engineers are still arguing about how best to salvage or repurpose it (or whether such a thing is even possible), but the vast treasure troves of data collected by Kepler are still yielding stunning discoveries. One of those discoveries just came to light this past week. In the constellation Lyra, there is an orange star 117 light years away from earth. The star is only 3/4th the size of the sun, but it is much older—dating back to 11.2 billion years ago (the sun, by comparison, is 4.567 billion years old). The universe itself is 13.8 billion years old—so the orange star has been burning through most of the history of creation. Because the orange star is smaller than the sun it has a much longer lifespan and will probably continue to fuse atoms together for another 20 billion years (whereas the dear sun, alas, will use up its fuel in another 4 or 5 billion years).
This is already heady stuff to think about, but not unprecedented. What is news is that Kepler discovered five small, rocky planets orbiting this ancient star—by far the oldest planets ever discovered. The planets are tiny—smaller than Earth and closer to 444 Kepler than Mercury is to our sun. In light of this discovery, the ancient orange star in Lyra has been designated as 444 Kepler.
444 Kepler is from one of the first broods of stars to exist. The fact that it has planets at all is something of a surprise. Astronomers are working to explain the genesis of such early planets. Of course this discovery raises other questions as well, about whether life could be much older than imagined. However to such questions there are still no answers. From the heavenly lyre of Orpheus, as from the rest of the firmament we have still heard nothing but silence.
