We Live In A Space Cloud

According to the latest data from IBEX (Interstellar Boundary Explorer, or IBEX), we are slowly traveling through a thin cloud of interstellar material, but are close to the boundaries. IBEX’s measurements of interstellar hydrogen, oxygen, and neon are the first–ever detections of these atoms by any spacecraft.

(An artist’s rendition of a portion of our heliosphere

Our entire heliosphere, which contains our Sun, the planets, and everything else in our Solar System, is moving through the interstellar medium. Because of this motion, a sort–of "breeze" of interstellar material moves toward our heliosphere’s boundary. The interstellar neutral atoms are just that – "neutral" – meaning they do not interact with magnetic fields. ISNs [interstellar neutral atoms] move through the boundary of our heliosphere without the boundary affecting them...

There appears to be a network of gas and dust clouds in our local galactic vicinity. While very dilute and thin, the general positions of these clouds can still be measured. As our heliosphere (and everything in it) orbits the center of our galaxy, we pass into and out of these clouds at various times...

Based on Ulysses results, previous science teams had concluded that our heliosphere was located in between two of the nearby clouds, the "Local Cloud" and the "G-Cloud" and transitioning into a new region of space. However, while the boundary of the Local Cloud is very close, IBEX results show the heliosphere remains fully in the Local Cloud, at least for the moment. "Sometime in the next hundred to few thousand years, the blink of an eye on the timescales of the galaxy, our heliosphere should leave the local interstellar cloud and encounter a much different galactic environment," Dave McComas [IBEX Principal Investigator] says.

Astronomer Fred Hoyle wrote about interstellar clouds encompassing the Earth in his 1957 novel Black Cloud. In the story, an astronomy grad student named Knut Jensen was going about the rather prosaic work of looking for supernovae. In the 1950's, the best way to do this was to take a picture of a patch of sky, and then take another picture a month or so later. The two pictures (or photographic plates) were placed side-by-side in a device called a "blink comparator" (called a 'blinker' in the story). By glancing first at one and then the other, any stars that suddenly become brighter are easily seen.

In a rich star field was a large, almost exactly circular, dark patch.

Further study demonstrated that this cloud was moving directly toward the sun, and that it appeared to demonstrate intelligence. Scientists puzzled over how an intelligent entity could control an enormous gaseous nebula, and decided that it must be done through the manipulation of magnetic fields within the cloud of gas:

"I imagine that the beast orders the material of the cloud magnetically, that by means of magnetic fields he can move materials wherever he wants inside the cloud."

Similar space clouds have menaced Earth in novels like "Exit Earth" by Martin Caidin and in the short story "Transience" by Arthur C. Clarke.
