A trillion years from now the universe will be a much simpler place for far-future astronomers to ponder.

One trillion years? Yes, when the universe is 100 times its presents age the only stars left will be the ones that are the longest burning: red dwarfs.

New star formation will have died out eons earlier, so there will be no iridescent nebulae, supernova blasts, or blue giant stars like Rigel in the constellation Orion.

Our Milky Way will have lost its identity long ago through merging with the Andromeda galaxy, M31. The resulting giant elliptical galaxy will be devoid of dust and gas.

The night sky will be a largely homogeneous sprinkling of stars. Stellar density will concentrate toward the galactic core. There will be no bright arch of the Milky Way to obscure the view all the way into the core.
