#5 billion light years across: the largest feature in the universe A Hungarian-US team of astronomers have found
what appears to be the largest feature in the observable universe: a ring of nine gamma ray bursts and hence galaxies-5 billion light years across.
The scientists, led by Prof Lajos Balazs of Kokoly Observatory in Budapest, report their work in a paper in Monthly Notices of the Royal Astronomical Society("A giant ringlike structure at 0. 78<z<0. 86 displayed by GRBS").
"Gamma-ray bursts (GRBS) are the most luminous events in the universe, releasing as much energy in a few seconds as the Sun does over its 10 billion year lifetime.
They are thought to be the result of massive stars collapsing into black holes. Their huge luminosity helps astronomers to map out the location of distant galaxies, something the team exploited.
They appear to be at very similar distances from us around 7 billion light years in a circle 36°across on the sky,
This implies that the ring is more than 5 billion light years across, and according to Prof Balazs there is only a 1 in 20,000 probability of the GRBS being in this distribution by chance.
This osmological Principleis backed up by observations of the early universe and its microwave background signature
which sets a theoretical limit of 1. 2 billion light years for the largest structures. The newly discovered ring is almost five times as large.

Besides the absolute speed of light passing from one point to another, light has speed another, measured by how fast the crests of a wavelength move, known as phase velocity.
This speed of light increases or decreases depending on the material it passes through. When light passes through water, for example, its phase velocity is reduced as its wavelengths are squeezed together.

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.
