Music of the spheres? Here’s a harp to play it on: Lyra, the harp of Orpheus, that almost brought his beloved back from death. The constellation has one of the sky’s brightest stars, a star that is really four stars, and a colorful donut.
Who Let the Dogs out?
Someone must have left the door open, because the skies are full of dogs. You can see the dogs of Orion and the hunting dogs of the shepherd Bootes in pursuit of the Great Bear. There is also the Running Dog Nebula and the memory of poor Laika, the first cosmonaut, who perished in space.
Pluto was once the last outpost of the Solar System. Now we realize that it's the gateway to the Kuiper Belt, a disk made up of rubble left over from the formation of the Solar System. The Kuiper Belt is big and it's cold and the Sun would just look like a bright star from there.
