#Exoplanet weather forecast calls for clouds University of Chicago rightoriginal Studyposted by Steve Koppes-Chicago on December 31 2013a team of scientists report they have characterized definitively the atmosphere of a super-Earth class
Previous studies of GJ 1214b yielded two possible interpretations of the planet s atmosphere. Its atmosphere could consist entirely of water vapor
or some other type of heavy molecule or it could contain high-altitude clouds that prevent the observation of what lies underneath.
and Jacob Bean of the University of Chicago has detected clear evidence of clouds in the atmosphere of GJ 1214b from data collected with the Hubble space telescope.
It transits or passes in front of its parent star every 38 hours which gives scientists an opportunity to study its atmosphere as starlight filters through it.
These clouds hide any information about the composition and behavior of the lower atmosphere and surface.
The planet was targeted next for follow-up observations to characterize its atmosphere. The first spectra which Bean obtained in 2010 using a ground-based telescope suggested that the planet s atmosphere either was predominantly water vapor
or hydrogen-dominated with high-altitude clouds. More precise Hubble observations made in 2012 and 2013 allowed the team to distinguish between these two scenarios.
The Hubble spectra revealed no chemical fingerprints whatsoever in the planet s atmosphere. This allowed the astronomers to rule out cloud-free atmospheres made of water vapor methane nitrogen carbon monoxide or carbon dioxide.
The best explanation for the new data is that there are high-altitude clouds in the atmosphere of the planet
though their composition is unknown. Models of super-Earth atmospheres predict clouds could be made out of potassium chloride
or zinc sulfide at the scorching temperatures of 450 degrees Fahrenheit found on GJ 1214b. ou would expect very different kinds of clouds to form than you would expect say on Earthkreidberg says.
Based on viewing angles from videos of the fireball researchers calculated that the meteoroid entered Earth s atmosphere at just over 19 kilometers per second slightly faster than had previously been reported. ur meteoroid entry modeling showed that the impact was caused by a 20-meter sized
The object broke up 30 kilometers up under the enormous stress of entering the atmosphere at high speed.
Evidence for water outside our solar system has previously been found in the atmosphere of gas giants
As the atmosphere of the Earth blocks the ultraviolet light such study can only be carried out from space.
Using a sophisticated computer model of the white dwarf atmosphere developed by Detlev Koester at the University of Kiel they were able to infer the chemical composition of the shredded minor planet.
Mohseni and colleagues use mathematical models to predict regions in the atmosphere and ocean that can give the vehicles a free ride toward their destination.

Considering observed concentrations of#carbon dioxide in the atmosphere passed an alarming threshold earlier this year,
When in the atmosphere, electricity exists as a magnetic field. The trick is to capture it safely to recharge devices.
We are seeing a fast growing trend towards harvesting water from the atmosphere, something our ancestors first began working on centuries ago.
The earth atmosphere is a far more elegant water distribution system than rivers, reservoirs, and underground waterways.
so what if the containers automatically added the water directly from the atmosphere once we took it home?
The reason for converting energy to microwaves is because it impervious to weather condition and water in the upper atmosphere.

otherwise recycle CO2 back into the atmosphere through the surface waters. But when they get eaten close to the seafloor by animals that never come to the surface all of the carbon these roving fish were packing gets locked down at the bottom of the ocean Trueman explained.
However the amount of carbon that deep-sea fish trap is compared miniscule with the emissions released into the atmosphere by humans.
or long-lived wood products to keep the carbon from the atmosphere, and then replanting with species that are suited slightly more to the changing climate."
and corals will produce less calcium carbonate as the amount of CO2 in the atmosphere rises,

#Solar magnetism twists braids of superheated gas Geoff Brumfiel hears from researcher Jonathan Cirtain why the Sun s atmosphere is hotter than its surface.
The Sun's atmosphere is just jam-packed full of magnetic field, says Cirtain. As the lines of those fields cross and twirl, the theory went,

which is essential for surviving a high-speed re-entry into Earth's atmosphere. The country is following a path blazed by other major spacefaring nations:
The dense atmospheres of gas giants Jupiter and Saturn contain carbon. Chemical modelling suggests pressure deep inside the planets would crush it into a rain of diamond chips
when life was emerging our young planet had an atmosphere oceans and primordial continents. But it did not yet have an ozone layer to shield the surface from the sun's harshest ultraviolet rays.
The inflatable technology is intended to help slow down vehicles after they enter the thin Martian atmosphere at supersonic speeds.
which is just 1 per cent as dense as Earth's. Unfortunately rocket-powered landings are out of the question too as the atmosphere is still just thick enough to buffet incoming spacecraft with more turbulence than thrusters can accommodate.
To simulate Mars's thin atmosphere On earth the team in Hawaii will first lift a test vehicle fitted with the LDSD system to about 37 kilometres above the Pacific ocean using a high-altitude balloon.
Earth is surrounded always by a bubble of magnetism called the magnetosphere which protects us from the bulk of the solar wind a stream of high-energy particles constantly flowing from the sun
. But sometimes the sun's magnetic field lines can directly link up with Earth's in a process called magnetic reconnection which opens up cracks in the magnetosphere.
Charged particles can flow along these lines into Earth's atmosphere leading to dazzling auroras as well as geomagnetic storms that can wreak havoc on navigation systems and power grids.
Gas in Earth's upper atmosphere is ionised by ultraviolet light from the sun and the resulting plasma becomes trapped by magnetic fields in a doughnut-shaped ring around the planet.
In January 2013 GPS sensors on the ground mapped electrons in the upper atmosphere and saw a tendril of increased electron density curling away from the north pole indicating that a plume of plasma was veering off towards the sun. At the same time three of NASA's THEMIS spacecraft
For the first time we were able to monitor the entire cycle of this plasma stretching from the atmosphere to the boundary between Earth's magnetic field
and deorbit allowing the debris spacecraft and net to burn up as they enter Earth's atmosphere.
JAXA thinks the net's main advantage is its simplicity#it's lightweight and doesn't require any propellant to move.
One concern is that the net will work very slowly taking several months or even a year to deorbit.
before spiralling in and burning up in Earth's atmosphere. Although they have made space accessible to groups who wouldn't otherwise have been able to afford it most recently a team of high-school students Cubesats haven't done much cutting-edge science."
A fleet of Cubesats with propulsion in orbit around a planet or moon can do a lot of things that big expensive satellites cannot, such as monitoring several locations in the atmosphere at once.
It will carry five scientific instruments including a methane sensor to try to pick up the gas in Mars's atmosphere.
On earth methane is produced mainly by life so there was a stir when Earth-based instruments and a European probe detected traces of it in Mars's atmosphere a decade ago.
Some are sceptical of those results believing they were triggered by methane in Earth's atmosphere
MOM may also help reveal how Mars became a cold dry planet with an atmosphere too thin to support liquid water for long periods.
Gaping canyons and river-like channels point to large amounts of water and therefore a thick warming atmosphere in the past.

About an hour later the Spectroscopic Planet Observatory for Recognition of Interaction of Atmosphere (SPRINT-A) separated from the launch rocket.
The Spectroscopic Planet Observatory for Recognition of Interaction of Atmosphere or Sprint-A will look at Venus
and Mars to find out why some worlds lose their atmospheres while others manage to keep a grip on their gases.
This will in turn help exoplanet hunters figure out which distant worlds are capable of hosting atmospheres that might support life.
Sprint-A will also peer at Jupiter's moon Io the most volcanically active body in the solar system to see how the tiny moon influences Jupiter's mighty auroras.
Extreme UV is a range of light suitable for observing planetary atmospheres says Shujiro Sawai of the Japan aerospace exploration agency (JAXA.
Extreme UV from the sun gets bent at the boundary where a planet's atmosphere meets space
But extreme UV radiation coming from space is absorbed by the Earth's atmosphere so it is not observable from the ground says Sawai.
So far our best clues to the original atmospheres of Mars and Venus come from the composition
and Venus probably had similar atmospheres long ago. But we also know that the sun pumps out a constant stream of charged particles called the solar wind
which can ionise gases in a planet's upper atmosphere and pick up the newly charged particles effectively sweeping them away.
Because Venus is closer to the sun the solar wind might have stripped gaseous water from its early atmosphere leaving a thick haze of mostly carbon dioxide that turned the planet's surface into a hellish desert.
It is thought the solar wind thinned the Red planet's atmosphere over time making it cold and dry.
It turns out that most atmospheres have lost a lot of gas over their lifetimes. On Mars it may be as much as 99 per cent.
For instance others have suggested that Mars lost its atmosphere all of a sudden during a powerful collision with an asteroid or comet.
A NASA probe called Maven due to launch in November will orbit Mars to study its atmosphere up close to try to solve the puzzle.
Sprint-A will help from afar by looking for the extreme UV radiation generated as the solar wind slams into the upper atmospheres of both Mars
By observing this phenomenon we will investigate how the solar wind affects the upper atmosphere of planets and how the planetary atmosphere escapes into outer space.

It will carry an oxygen supply to work outside of the atmosphere. Basically it's a rocket engine that can utilize oxygen out of the air only
This saves on the weight of oxygen that would otherwise be needed for the flight through the atmosphere.
The Japan aerospace exploration agency sent the first of its new generation of launch vehicles into orbit carrying a telescope that will observe the atmospheres of Venus Mars and Jupiter.
They play a complex role in the atmosphere and in any potential climate change scenario. But rudimentary data has simplified their role in simulations leading to variability among climate models.

which means the terminal velocity of the robots#the fastest they will fall in Titan's thick atmosphere#is about 33 mph roughly equivalent to the speed reached after a 30-foot drop On earth.
since the red planet has both a thinner atmosphere and stronger gravity than Titan meaning they would reach a higher terminal velocity.
The investigation showed the streaks absorb light at specific wavelengths associated with chemicals known to pull water from the Martian atmosphere in a process known as deliquescence
