This light bounces off air molecules and small particles such as dust, ice and droplets of water in the atmosphere.
#Astronomers discover powerful aurora beyond solar system Astronomers have discovered the first aurora ever seen in an object beyond our Solar system.
The aurora similar to the famous orthern Lightson Earth is 10,000 times more powerful than any previously seen.
They found the aurora not from a planet, but from a low-mass star at the boundary between stars and brown dwarfs.
the scientists said. ll the magnetic activity we see on this object can be explained by powerful auroras,
and brown dwarfs have outer atmospheres that support auroral activity, rather than the type of magnetic activity seen on more-massive and hotter stars.
The aurora the scientists observed from LSR J1835+3259 appears powered by a little-understood dynamo process similar to that seen on larger planets in our Solar system.
some as small as a grain of sand, entering the Earth atmosphere at high speed.
On entering the atmosphere, these particles heat the air around them, causing the characteristic streak of light seen from the ground.

The sediment-based microbes form an important methane sink preventing much of the chemical from reaching the atmosphere
Studies have found that approximately 3-6 percent of the methane in the atmosphere is from marine sources
According to the research study published in Nature Communications today the Sun affects middle atmosphere ozone with potential implications on smaller scale to regional but not global climate.
Humankind is responsible for the global warming of our climate by increasing the amount of greenhouse gases in the atmosphere.
However according results published today fluctuations in the activity of the Sun impact middle atmosphere ozone providing a potential link to regional scale climate variability.
The detected ozone variation may in part help understand the alternation of local mild and cold winter seasons as hints have been obtained in previous research that the ozone changes in the middle atmosphere may link as far as the surface of Earth
The research team was able to confirm for the first time the long-term implications of solar-driven electron impact on the upper middle atmosphere ozone.
The ozone variation between the extremes of the Sun's activity is so great that it is likely to impact the temperature balance of the atmosphere.
Auroras and ozone lossaccording to the research study conducted by the Finnish Meteorological Institute University of Otago
and The british Antarctic Survey the electrons similar to those behind the aurora cause significant solar cycle variation in the polar mesosphere ozone.
when more electrons enter the atmosphere. These results are only the first step but an important one allowing us to better understand the long-term impacts of this type of solar activity
and enter the atmosphere in the polar regions. In the atmosphere the electrons ionize gas molecules leading to the production of ozone-depleting catalyst gases.
Based on currently available satellite observations electron precipitation may during solar storms lasting a few days reduce ozone in the upper atmosphere (60-80 km) as much as 90 per cent on a momentary basis

Both are abundant in Earth atmosphere -and would be needed for any humans hoping to breathe on Mars without a spacesuit.
As air from the atmosphere passes through the vehicle air filter, it then passes unobstructed through the converter ring located in the air intake duct.
which would strip away our atmosphere and surface water and bombard us with radiation if left unchecked.
and Aurora presented as successors to Edison, Titan, and Mira (respectively). While Cori and Summit were announced previously,
this is the first time that we are hearing about Aurora, which along with Summit and Sierra, falls under the CORAL collaboration framework.

The more greenhouse gases emitted into the atmosphere, the warmer the atmosphere becomes, exacerbating global climate change. Solving the problem is not so simple, especially with regards to aviation the source of two-percent of the annual greenhouse gas emissions from human activity.
While biofuels have proven to be an effective, renewable, low-carbon alternative to gasoline and diesel, jet fuels pose unique challenges.
The concentrations of carbon and other greenhouse gases in Earth atmosphere are now at their highest levels in the past three million years, primarily as a result of the burning of petroleum and other fossil fuels.
while operating within the Earth atmosphere. Whether, as Musk has suggested, Spacex service could also be a viable alternative for customers in the developed world is less certain.
but it also releases the organic materialscarbon components into the atmosphere, which wind up trapping heat.
Since farm waste and fats have already been exposed to the atmosphere and have absorbed carbon during their lifetime,
However, prior to the declaration of weak, moderate or strong El niño, the atmosphere must display signs of its response to the sea surface temperatures anomalies.
it releases heat at a specific wavelength of infrared light that passes easily through the atmosphere and out into space.
Since nothing in the atmosphere can absorb that, the heat directly passes straight into space.
But it was accompanied not by increased convection in the lower atmosphere, typically spawning thunderstorms and weakening surface trade winds.
