The bubble emissions are much more energetic than the gamma-ray fog seen elsewhere in the Milky Way, and appear to have defined edges, suggesting it formed as a result of a large and rapid energy release.

Bubble The false vacuum decays in a manner similar to the way water boils, forming bubbles of normal matter in the midst of the false vacuum, just as bubbles of steam form in the midst of water heated past its boiling point.
Our Bubble of Interplanetary Space The "vacuum" of interplanetary space includes copious amounts of energy radiated from the Sun, some interplanetary and interstellar dust (microscopic solid particles) and gas, and the solar wind.
LOCAL BUBBLE (LB) - Cavity of ~100 pc radius that may have been formed by a supernova explosion and a density of ~0.005-0.05 atoms/cm3 - at least 10 times lower than the average interstellar medium (ISM) in the Galaxy.
local bubble or void: A region of high-temperature, low-density gas in the interstellar medium in which the sun happens to be located.
RADIO BUBBLE The "radio bubble" is a sphere centered on Earth that is expanding at the speed of light (the speed of radio transmissions).

The superbubble is nearly 23,000 light-years from Earth. The astronomers discovered it by combining numerous smaller images made with the GBT into one large image.
The Local Bubble was created by a shock wave (or more than one). The question that is still open for debate is what created it? Some astronomers hold that it was created by shock waves from star formation in the near by nebulae.
The Local Bubble contains about 200,000 stars and extends for hundreds of trillions of kilometers, or nearly 100 pc. It was probably carved out by a supernova explosion that occurred in these parts roughly 100,000 years ago.
The "soap-bubble" or foamlike geometry revealed by large-scale redshift surveys has given rise to mathematical treatments of the walls and voids.

Studies indicate that a fair portion of them are caused by strong temperature or moisture gradients, or both, such as might be found near the boundaries of bubbles of especially warm or moist air (see blob).
A bubble of gas that is hotter than its surroundings expands and rises. When it has cooled by passing on its extra heat to its surroundings, the bubble sinks again.
These irregular surface features are sort of like bubbles. By viewing the photosphere with special telescopes, this bubbled surface can be easily seen.
In sonoluminescence, acoustic shock waves create temporary bubbles that collapse shortly after creation, producing very high temperatures and pressures. In 2002, Rusi P.
Apart from the difficulty of seeing how the bubbles could arise, there is a formidable objection, mentioned by E. W. Briicke (Pogg. Ann. 88, 363), that the blue of the sky is a much richer colour than the blue of the first order.
Coronal mass ejections (or CMEs) are huge bubbles of gas threaded with magnetic field lines that are ejected from the Sun over the course of several hours.
The arrangement of the superclusters and voids looks like a bunch of soap bubbles or swiss cheese with the galaxies on the borders of the huge holes.
In aerial navigation a bubble octant—sometimes called a bubble sextant—is used, in which a spirit level is reflected into the field of view in such a way that the center of the bubble indicates the true horizon.
The LIC is itself surrounded by a larger, lower density cavity in the interstellar medium (ISM) called the Local Bubble, that was probably formed by one or more relatively recent supernova explosions.
Two large stellar nurseries form big bubbles in space in this new image from WISE, a small space telescope. Known as the Heart (left) and Soul nebulae, they span a combined 580 light-years.
It appears that our own Solar System is located inside one of these bubbles of hot coronal gas. The so-called Local Bubble is estimated to be about 650 light years across, have a density of ~0.
As the solar wind moves out into space, it creates a magnetized bubble of hot plasma around the Sun, called the heliosphere. Eventually, the expanding solar wind encounters the charged particles and magnetic field in the interstellar gas.
Stokes' Law deals with the way that a bubble rises in a liquid. The rate of rise is directly proportional to the heat, pressure and viscosity of the liquid. Glass is a liquid that follows these laws and may form in one of two ways.
As the solar wind expands supersonically into space, it creates a magnetized bubble around the Sun -- the heliosphere. Eventually, the solar wind runs into the electrically-charged particles and magnetic field in the interstellar gas.
Most of the hot gas forms a pair of expanding bubbles above and below the equatorial disk.
Although they are far from the Sun, solar heating is still sufficient to cause particles to bubble off the surface of the comet's nucleus. The spacecraft flew within 240 kilometers (149 miles) of Wild-2.
As the expanding shell moves through the interstellar medium it sweeps up material to form a giant bubble. The appearance of an SNR is basically spherical but there are random filamentary structures throughout.
Some of the eruptions were driven by dissolved gases, as shown by the presence of vesicles (bubbles) in certain samples and by the existence of pyroclastic glass (essentially volcanic ash) at some locations.
Skylab's ATM also observed huge bubbles of plasma rising occasionally (every 2 days or so) from the Sun.

The magnetosphere is a bubble of charged particles trapped within the magnetic environment of the planet. In this picture, a magnetic field is sketched over the image to place the energetic neutral atom emissions in perspective.
This inhomogeneous galaxy distribution gives the universe a mottled appearance, as if the universe were built of empty bubbles enclosed by walls of galaxies.
These stars continually eject their outer atmosphere in bubble-like shells of particles and gas (and creating a strong stellar wind). About 200 of these stars are known in the Milky Way; most of these are very far from us.
The bubble around the Sun where the solar winds are still strong enough to blow outward is known as the heliosphere.

These cavities may be relic gas bubbles that formed before the rock crystallized, or they make have started out as solid spheres that became separated from the crystal phase during later stages of rock formation.

The heliopause is the outermost boundary of the solar wind, where the interstellar medium restricts the outward flow of the solar wind and confines it within a magnetic bubble called the heliosphere.
Explosive volcanic eruptions occur when magma rising from below has much dissolved gas in it; the reduction of pressure as the magma rises causes the gas to bubble out of solution, resulting in a rapid increase in volume.
Image credit: European Space Agency By the time Ulysses had completed its first orbit in 1998, our knowledge of the heliosphere (the huge bubble which marks the extent of the solar wind) had taken a dramatic step forward.

It also created a subspace bubble around the Defiant, isolating it from changes to the timeline inadvertently effected by the three officers.
