Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel; have you seen "Interstellar?") and, if that were true, it would be "stable and navigable."

Visiting Interstellar's Spacecraft

I had an opportunity to stand next to a spaceship from the film "Interstellar" last Friday and fly through a simulation of yet another spacecraft from the film.

The new Paramount film "Interstellar" imagines a future where astronauts must find a new planet suitable for human life after climate change destroys the Earth's ability to sustain us.

Voyager 1 Has Left Our Solar System

Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.

NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.

Thirty-five years ago yesterday, NASA's Voyager 2 spacecraft, the first Voyager spacecraft to launch, departed on a journey that would make it the only spacecraft to visit Uranus and Neptune and the longest-operating NASA spacecraft ever.

Data from NASA's Voyager 1 spacecraft indicate that the venerable deep-space explorer has encountered a region in space where the intensity of charged particles from beyond our solar system has markedly increased. Voyager scientists looking at this rapid rise draw closer to an inevitable but historic conclusion - that humanity's first emissary to interstellar space is on the edge of our solar system.

Using Pulsars To Navigate in Space

Autonomous Spacecraft Navigation Based on Pulsar Timing Information

"Pulsars are rapidly rotating neutron stars that are observable as variable celestial sources of electromagnetic radiation. Their periodic signals have timing stabilities comparable to atomic clocks and provide characteristic temporal signatures that can be used as natural navigation beacons, quite similar to the use of GPS satellites for navigation on Earth."

Keith's note: This is the plaque placed on the Voyager 1 and 2 probes, now heading out of our solar system into interstellar space. According to Wikipedia: "The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given."
