Radiation can be dangerous for astronauts who do work on the outside of the International Space Station. Solar activity can affect satellite electronics and limit their lifetime.

These predictions can help them forecast these solar conditions, called space weather.ДЇorecasting of the solar cycle can help scientists protect our radio communications on Earth, and help keep NASA satellites and astronauts safe, too. Scientists work hard to improve our ability to predict the strength and duration of solar cycles. Other cycles can have very few sunspots and little activity. Some cycles have maximums with lots of sunspots and activity. Extreme eruptions can even affect electricity grids on Earth.ДЄn image of a coronal mass ejection observed by NASAвЂ™s Solar and Heliospheric Observatory, or SOHO, satellite in 2001. For example, eruptions can cause lights in the sky, called aurora, or impact radio communications. These eruptions send powerful bursts of energy and material into space. Giant eruptions on the Sun, such as solar flares and coronal mass ejections, also increase during the solar cycle.

The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots. Over time, solar activity-and the number of sunspots-increases. The beginning of a solar cycle is a solar minimum, or when the Sun has the least sunspots. One way to track the solar cycle is by counting the number of sunspots.

Every 11 years or so, the Sun's magnetic field. The Sun's magnetic field goes through a cycle, called the solar cycle. This charged gas moves, generating a powerful magnetic field. Our Sun is a huge ball of electrically-charged hot gas. HereвЂ™s a simplified explanation of the greenhouse effect on the EPAвЂ™s website. The solar cycle is the cycle that the SunвЂ™s magnetic field goes through approximately every 11 years. WeвЂ™ve also got an interesting article that talks about a real greenhouse on the Moon by 2014. Read about the greenhouse effect taking place in Venus here in Universe Today.

The Earth is not the only planet that experiences the greenhouse effect. Known as the greenhouse effect, this is the reason why heat can build up some more. The presence of greenhouse gases make the atmosphere absorb more heat, reducing the fraction of outbound EM waves that pass through. Naturally, the ones that get absorbed add to the heat already there. Upon reaching the atmosphere, part of it gets absorbed and part of it passes through.

Preheat the oven to 350 F (176 C) and line an 8 x 8-inch baking dish with. In the meantime, the electromagnetic radiation that wasnвЂ™t absorbed by the atmosphere proceeds to the EarthвЂ™s surface and heats it up. Some of this heat is re-radiated to outer space while some is sent to the EarthвЂ™s surface. In particular, UV is absorbed by the ozone layer and re-emitted as heat, eventually heating up the stratosphere. When electromagnetic radiation from the Sun strikes the EarthвЂ™s atmosphere, some of it is absorbed while the rest proceed to the EarthвЂ™s surface. This was later confirmed by JapanвЂ™s Yohkoh, a satellite launched in 1991. X-ray radiation from the Sun was first observed by T. By the time they get to the surface, their frequencies are mostly only within the IR/visible light/UV spectrum.Дuring solar flares, the Sun also emits X-rays. However, as the gamma ray photons make their arduous journey to the surface of the Sun, they are continuously absorbed by the solar plasma and re-emitted to lower frequencies. The culprit for speedy solar winds are coronal holes. Fusion in the core actually gives off high energy gamma rays. The origin of the fast stream of solar wind was identified in 1973 using X-ray images taken of the sun's corona from Skylab. Actually, the Sun does not only produce IR, visible light, and UV.
