The stars, nebulae and galaxies are cooling off, leading to the death of the universe. This is an amateur astronomy shot of the Horsehead Nebula, taken by Rawastrodata. Used by permission and with Creative Commons License.
While I was out learning how to manipulate the universe inside the Digistar 5 last week, a news story broke about how the universe is slowly dying. Astronomers are doing a survey of galaxies of all shapes and sizes in 21 wavelengths of light, and have discovered that the energy being produced by stars, nebulae, and galaxies in a surveyed portion of the cosmos is about half of what it was just two billion years ago.
