Transparent photographs of the Solar’s environment nonetheless display coronal rain and dancing plasma
New images that are the most resolutions for the surface of the sun and its corona, will help scientists to solve mysteries about how storms on the sun develop. This can improve space weather forecasts and help prevent interruption in technology on Earth.
Pictures were part of one recent study Published in Nature Astronomy.
Anyone who has seen the total eclipse of the sun is a witness to the glowing halo around our star, which is known as Corona. This envelope of extremely hot gas spreads in space at a distance of millions of kilometers and where violent explosions occur. These bursts of electric charged gas can blow the sun and reach the earth in all ways, Satellites and power grid,
It shines on one of the big secrets about the Sun. Scientists have not fully understood why corona can be warm several times compared to the surface of the sun. Some are pumping energy in the Sun’s atmosphere. A problem has been lacking at its base, where it is a lack of comments of Corona, where it meets the surface and where violent activity arises. Nature provides a brief glimpse during solar eclipse when the moon covers the bright surface of the sun that allows the dimer corona to shine, but continuous observations have been more difficult.
The binoculars on the ground trying to study the weather on the sun have been interrupted by our own weather. Turbulence in our atmosphere blur images through the same effect that makes stars twinkle at night.
now though, New adaptive optics The 1.6 -meter God in California has reduced the flickering effect of our environment on the solar telescope with a factor of ten. This improvement allows us to look at features at 63 km resolution, which is closer than ever. The trick was a flexible mirror that shapes 2200 times per second, as it happens, compensation and correct for atmospheric deformation.
This resulted in the highest resolution images and films made of the border between the surface of the Sun and the corona.
Surprisingly beautiful images suggest that looks like a fluffy surface on the sun, which rises with giant loops, appears to dance and rotate with the magnetic field of the Sun. Meanwhile, cooler coronal raindrops, which may be more than 20 kilometers wide, fall back down. Comments suggest that some scientists have never seen before: a plasma stream that they are saying “plasmoid”, running at 100 kilometers per second on the solar surface.
This is the region where solar flares and coronal mass ejections produce giant drops of many times larger electric charged materials than the Earth, which explode the Sun and attack the magnetic field of our planet. The result is beautiful northern and southern lights, but satellites also have a blackout on electronics and the increase in electrical grids.
A dramatic example of this effect Came in 1989 When a coronal mass ejection closed the Quebec Power Grid, most of the provinces were put in darkness for nine hours. Since then, the power system against such events has been rigid, but with greater dependence on GPS satellites, navigation systems may still be interrupted. Even astronauts at the International Space Station need to take shelter in their spacecraft to avoid harmful radiation effects of solar flares. Future astronauts on the moon will be under similar hazards from solar storms.
It is challenging to predict violent solar events because the surface of the sun is a complex, violent place that is ever changing, partly due to the fact that our star’s equator rotates faster than the poles. It causes disturbance in hot ges and bends the powerful magnet area into the loops that can snap, releasing the material into space. The Sun also passes through chakras every 11 years where solar activity is wax and wans. We are currently in the period of solar maximum, so it is important to monitor its activity.
These new corrective lenses, which can also be fitted in other solar telescopes, will enable scientists to dive into the secret as to why corona is so hot and how solar disturbances arise. This can improve predictions in space season so that the warning can be released in advance.
With the weather on Earth, an accurate long -term weather forecast may be important. Hopefully it would mean that we are looking at the space weather more clearly.
