the gas out of a formation called the Barnett Shale.
Not exact matches
Powerful radiation from supermassive black holes at the center
of most large galaxies creates winds that can blow
gas out of the galaxies, halting star
formation.
In recent years, technological advancements have enabled firms to use horizontal, and not just vertical, drilling to exploit rock

gas - rich Marcellus Shale
formation across New York and Pennsylvania.
Some researchers have suggested that these

out by the volcanic eruptions that produced the Siberian traps, a vast
formation of volcanic rock produced by the most extensive eruptions in Earth's geological record.
He points
out, however, that the EIA's most recent assessments
of the total amount
of gas that can be recovered from major shale
gas areas,
formations such as Marcellus and Texas's Barnett, have fallen rather than risen.
These strong stellar winds also carve
out cavities in nearby clouds
of gas and dust, and kickstart the
formation of new stars.
Depleted oil and
gas reservoirs and aquifers could leak hydrogen, and cycling — filling a storage site, pulling hydrogen
out for use and refilling the site — can't be done more than once or twice a year to preserve the integrity
of the rock
formation, Lord said.
Although in the short term strong stellar winds through
gas clouds can instigate star
formation, in this case the
gas blown
out of the galaxy's inner regions will eventually strip the galaxy
of the ingredients for future star growth.
Some astronomers have suggested that they formed suddenly
out of collapsing
gas clouds, but most suspect that the supermassive black holes grew after their initial
formation.
The properties
of the pores also determine how
gas will flow
out of the
formation.
Fracking relies on the high - pressure injection
of water, sand, and other chemicals to create microfractures in rock
formations, thereby making it easier to draw
out oil and
gas.
Lagrange says the finding is consistent with a planet
formation model known as core accretion in which the planet starts
out as a rocky core that gravitationally acquires more matter from the surrounding swarm
of dust and
gas.
The explosions drive huge amounts
of gas out of the galaxies and with most
of the rest consumed in star
formation, the galaxies soon run
out of fuel.
«If you can't turn the well so it goes along the shale
formation and a lot
of the well is exposed to the
gas, you can't get the
gas out economically,» says Anthony Ingraffea, a hydraulic fracturing expert and professor
of civil and environmental engineering at Cornell University.
In addition many theoretical studies
of the
formation of planetary systems
out of contracting clouds
of interstellar
gas and dust imply that the birth
of planets frequently if not inevitably accompanies the birth
of stars.
One possibility called
out by the authors would be icy comets bombarding Earth after
formation and delivering their own distinct cocktail
of compounds and
gases to an existing atmosphere evolved from a solar source.
The two teams and others will continue to scour
gas clouds for other complex organic molecules to fill
out the picture
of life
formation.
In a review
of the potential health impact
of fracking, which involves the pumping
of water and chemicals into dense shale
formations to push
out gas and oil, Public Health England (PHE) said any health impacts were likely to be minimal.
Therefore, high - resolution follow - up optical observations were performed by the Hubble Space Telescope to reveal «beads on a string» at the center
of SpARCS1049 +56 which occur when, similar to a necklace, clumps
of new star
formation appear strung
out like beads on filaments
of hydrogen
gas.
In the image accompanying this article, the velocity - distribution data indicates the
formation of a Bose — Einstein condensate
out of a
gas of rubidium atoms.
In fact, the ring - like shape is the result
of the gravitational disruption caused by a small intruder galaxy passing through a large one, compressing the interstellar
gas and dust, and causing a wave
of star
formation wave to move
out from the impact point like a ripple across the surface
of a pond.
Researchers think these bubbles drag trails
of relatively cooler
gas (about 1 million degrees), and as the bubbles detach from the jets and drift farther
out into the galaxy, the cooler
gas trails become even cooler, becoming extremely cold (just slight above absolute zero), and rain back on the black hole as fuel for star
formation.
The huge
gas emissions — which flow
out like the wings
of a butterfly around the black holes — might be switching off star
formation in the galaxy.
This would show the structure
of the so - called «cosmic web» that galaxies are embedded inside, and how chemically enriched
gases flow in and
out of a galaxy to fuel star
formation.
One study showed that the
gas being stripped
out included the cool, denser
gas that is the source
of continued star
formation and so the galaxies appear to be dying from a lack
of new stars being formed.
With bitters, digestive enzyme secretions are increased, helping to promote the complete breakdown
of nutrients into their absorbable units, preventing
gas formation when large molecules are acted upon by bacteria further down the small intestine.2, 11 The complete breakdown
of proteins is particularly important, as the cross reactivity
of immune cells between undigested protein molecules and intestinal cells plays an important role in the etiology
of conditions such as celiac disease.15 Insulin and glucagon secretions are stimulated, helping to stabilize blood sugar levels.3, 11 Many bitters formulations have been traditionally used in the treatment
of type 2 diabetes, and it is interesting to point
out that many naturally sweet substances are often paired with some bitterness in nature.4, 11 Herbalist Jim McDonald hypothesizes that our cravings for sweetness may mask cravings for bitterness for this reason.4
Four foot - long canisters fall
out of the sky and crash - land in four locations: A silverback gorilla approaches a canister that sprays
gas on him, he rushes away and is found with a dead bear with blood across its shoulders (we hear he snapped its neck and we see bloody slashes on his chest in the
formation of a bear claw).
This means that instead
of drilling
gases out of the bottom
of the planet, there is now a push to capture carbon dioxide (CO2) from the
gases discarded by industry and transporting and injecting it into underground geological
formations.
High - volume hydraulic fracturing has been combined with horizontal drilling over the past decade to force oil and natural
gas out of shale and other tight geological
formations by fracturing the rock with high - pressure injection
of water, sand, and chemicals.
The problem is that natural
gas is methane, a powerful greenhouse
gas in its own right, and when you extract natural
gas from shale
formations, some
of it inevitably leaks
out.
