Sentences with phrase «lighter hydrogen atmosphere»
We suspect that water, the constituent of Saturn's deepest cloud deck, can suppress convection in the lighter hydrogen atmosphere for a period of decades, until finally buoyancy wins out and a large convective outburst ensues.

Heaven is that planet 35000 light - years from earth, ten times as big made of hydrogen and oxygen for water, gold as atmosphere (yes we're taking the gold) But to desist as soul when given the chance in hell if you truly believe seems impassible for me to fathom.
For instance, if the earth were slightly larger, hydrogen, a light gas, could not escape into the atmosphere at its prescribed rate (due to an increase in the earth's gravitational field), and over time would build up and cause life to cease.
If the earth were slightly larger, having a stronger gravitational force, it would prevent hydrogen, a light gas, from escaping at a specified rate, building up in our atmosphere and eventually rendering our planet lifeless.
As expected, scientists observed light, charged particles like hydrogen and helium ions leaving Venus's atmosphere.
At altitudes above 50 kilometers, ultraviolet light from the sun easily penetrates the Red Planet's thin atmosphere and breaks down water's chemical bonds between hydrogen and oxygen.
Essentially composed of hydrogen, it absorbs the ultra violet light emitted by the star and the phenomenon remains invisible on Earth because the ultra violet light is blocked by the atmosphere.
Huygens will sample methane in the atmosphere and measure the relative abundance of light hydrogen and heavy hydrogen to produce a chemical fingerprint that will enable scientists to compare Titan's composition with that of comets.
«While we expected to see some red in Saturn's aurora because hydrogen emits some red light when it gets excited, we also knew there could be color variations depending on the energies of the charged particles bombarding the atmosphere and the density of the atmosphere,» Dyudina said.
Such physical changes to the atmosphere might last only hours or days, he notes, but any subtle chemical changes — including those resulting from the extra hydrogen added to the air when ultraviolet light breaks down the water vapor — would persist much longer.
If there were too much UV light, no water could survive on the surface because the water molecules would break up and escape through the top of the atmosphere as hydrogen and oxygen gas.
The favoured idea is that water is responsible, but some argue that hydrogen peroxide and ozone, which might be created when ultraviolet light breaks down the carbon dioxide and oxygen in the Martian atmosphere, could be involved.
Phase V hydrogen, created by crushing Earth's lightest element with mind - boggling pressures, gives the physicists a glimpse of the inner atmosphere of a gas giant, where pressures reach millions of (Earth) atmospheres
The storms can vault water vapor up to 80 kilometers into the planet's atmosphere, where ultraviolet light breaks down the vapor into hydrogen and oxygen.
Smaller planets like ours have lost the light elements in their atmospheres, such as hydrogen and helium, but the greater gravity of 55 Cancri e has held onto them.
One of three main outer layers that make up the sun's atmosphere, the chromosphere often appears red as superheated hydrogen emits light.
As the particles journeyed around Earth, the lighter hydrogen particles were lost in collisions with the atmosphere, leaving an oxygen - rich plasma.
With too much UV light, no water could persist on the surface because its molecules would break down into hydrogen and oxygen gas and escape through the atmosphere.
Since the lighter version escapes more often, over time, the Martian atmosphere has less and less hydrogen compared to the amount of deuterium remaining.
C. Carreau, ASPERA - 4 & MAG teams, Venus Express, ESA Annotated image illustrating loss of hydrogen through plasma wake Venus may have lost oceans of water due to a runaway greenhouse effect which evaporated water into the upper atmosphere, where ultraviolet light dissociated water into ionized atomic hydrogen and oxygen (some later incorporated into carbon dioxide) that were blown away by the Solar wind due to the lack of a strong magnetic field like the Earth's (more).
The results quantify the nature of gas molecules containing carbon, hydrogen, and sulfur in the earliest atmosphere, but they shed no light on the much later rise of free oxygen in the air.
It says nothing about CO2 ′ s greenhouse effect because it reports the upper atmosphere absorbing high velocity helium and hydrogen and other particles, not infra - red light.
Once this happens, it is easy for the water vapor to decompose in the upper atmosphere, whereafter the light hydrogen escapes and oxygen either escapes or reacts with rocks.
When water molecules rise high in an atmosphere, ultraviolet radiation split the water molecules into its component gases, oxygen and hydrogen, and the lighter hydrogen molecules escape into space.
