#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.
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 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.

#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.
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.
Previous evidence strongly suggested that brown dwarfs shared the same formation mechanism as their larger siblings
Based on this discovery, e conclude that the formation of brown dwarfs is scaled a-down version of the process that forms larger stars,

It well known that focusing sunlight makes it possible to use smaller cheaper solar cells. But this is usually done with lenses or mirrors,
