Discussion – How do we stay in touch with mother Earth?

The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star's life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the 'hourglass.' The unprecedented sharpness of Hubble's images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.

Communication technologies may have to advance greatly. Carrier wave frequencies may have to be reconsidered. Perhaps modulation with rays that are already passing like gamma rays or other by may be an option. They already have momentum so resonant circuits may perhaps not need their own energy source.
