#Solar activity impacts polar ozone The increase in greenhouse gases explains to a large extent the rise in the average temperature of Earth.
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.
This climate variability is not a trend like climate change but rather year-to-year fluctuations following solar activity.
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 its role in regional climate variability says Dr Monika Andersson who lead the study at Finnish Meteorological Institute.
Earth's radiation belts are regions in near-Earth space that contain vast quantities of solar energetic electrons trapped there by Earth's magnetic field.
During magnetic storms which are driven solar wind the electrons accelerate to high speeds 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

Along with gravity the electromagnetic interaction and weak nuclear force strong-interactions are one of four fundamental forces. Lead scientist Professor Tim Gershon from The University of Warwick's Department of physics explains:
Gravity describes the universe on a large scale from galaxies to Newton's falling apple whilst the electromagnetic interaction is responsible for binding molecules together
and also for holding electrons in orbit around an atom's nucleus. The strong interaction is the force that binds quarks the subatomic particles that form protons within atoms together.
It is so strong that the binding energy of the proton gives a much larger contribution to the mass through Einstein's equation E=mc2 than the quarks themselves. 3 Due in part to the forces'relative simplicity scientists have previously been able to solve the equations behind gravity

#Astronomers Discover Disilicon Carbide in Space After decades of speculation and searching, astronomers have discovered the important dust-forming molecule Si-C-Si (disilicon carbide) in space.
The space between stars is not empty it contains a vast reservoir of diffuse material with about 5-10%of the total mass of our Milky way galaxy.
Most of the material is gas, but about 1%of this mass (quite a lot in astronomical terms) takes the form of tiny dust grains made predominantly of silicates (sand is also silicates),
The dust grains contain a large fraction of many important elements in the universe like silicon
They are essential to the chemistry that takes place in the interstellar medium by providing gas molecules with a surface on
what astronomers can see and control much of the energy balance in the interstellar medium. Not least, in the early stages of a star evolution the dust can coagulate into large clumps the first step towards forming planets.
Where does all this dust come from? Interstellar grains are synthesized in two main types of sources:
the inner winds of a class of evolved stars, and the ejecta of supernovae. The grains form out of molecular seeds.
In evolved stars, such seeds might be molecules like Tio, VO, Zro, C 2, CN, or C 3, species that have been known for a hundred years;
supernovae also have numerous possible constituent elements. Because the carbon monoxide (CO) molecule is extremely stable,
Carbon-rich stars are ones that have this excess carbon. The dust forms from nucleation seeds that grow as molecules condense onto it via numerous steps that are still quite mysterious,
Now Cfa astronomers Mike Mccarthy, Carl Gottlieb, Nimesh Patel, N. Reilly, and Ken Young and their colleagues have reported detecting 112 transitions of the disilicon carbide in the extended atmosphere of the evolved, carbon-rich star RW Leo.
Their success is largely due to their own, new laboratory measurements that determined more accurate values for the line frequencies.
The team then used the Submillimeter Array and the IRAM submillimeter telescope to search in RW Leo,

#First Direct evidence of the Formation Process of Brown dwarfs Using the Very Large Array, an international team of astronomers has discovered jets of material ejected by still-forming young brown dwarfs,
revealing the first direct evidence that brown dwarfs are produced by a scaled-down version of the same process that produces stars.
The astronomers studied a sample of still-forming brown dwarfs in a star-forming region some 450 light-years from Earth in the constellation Taurus,
and found that four of them have the type of jets emitted by more-massive stars during their formation.
The jets were detected by radio observations with the VLA. The scientists also observed the brown dwarfs with the Spitzer
and Herschel space telescopes to confirm their status as very young objects. his is the first time that such jets have been found coming from brown dwarfs at such an early stage of their formation,
and shows that they form in a way similar to that of stars, said Oscar Morata, of the Institute of Astronomy and Astrophysics of the Academia Sinica in Taiwan. hese are the lowest-mass objects that seem to form the same way as stars,
he added. Brown dwarfs are less massive than stars, but more massive than giant planets such as Jupiter.
They have insufficient mass to produce the temperatures and pressures at their cores necessary to trigger the thermonuclear reactions that power ormalstars.
Theorists suggested in the 1960s that such objects should exist but the first unambiguous discovery of one did not come until 1994.
A key question has been whether brown dwarfs form like stars or like planets. Stars form when a giant cloud of gas
and dust in interstellar space collapses gravitationally, accumulating mass. A disk of orbiting material forms around the young star,
and eventually planets form from the material in that disk. In the early stages of star formation, jets of material are propelled outward from the poles of the disk.
No such jets mark planet formation, however. Previous evidence strongly suggested that brown dwarfs shared the same formation mechanism as their larger siblings
but detecting the telltale jets is an important confirmation. Based on this discovery, e conclude that the formation of brown dwarfs is scaled a-down version of the process that forms larger stars,
Morata said. Morata led an international team of astronomers with members from Asia, Europe, and Latin Americ
