Some sunspots -- such as one in 2004 that measured 20 times the size of our planet -- are big enough to be seen by the naked eye. Keep in mind, however, that staring directly at the unfiltered sun is an extremely bad idea because it can harm your eyes.

Well, UVB can harm your plants, just like it can humans. Unfortunately, we can't give our plants sunglasses or sun block, but Mother Nature has an answer. ... There is more UVB the higher up you go, so plants that grow there will naturally have more trichomes and higher potency.

In short: yes, they can be. According to the World Health Organisation, sunbeds are as dangerous as smoking. Like the sun, they give out harmful UV rays, that damage the DNA in your skin cells - which over time, can lead to malignant melanoma - the deadliest form of skin cancer.

UV rays from sunbeds Sunbeds, sunlamps and tanning booths give out the same type of harmful radiation as sunlight. UVA rays make up about 95% of sunlight. They can cause your skin to age prematurely, making it look coarse, leathery and wrinkled.

Tanning equipment is NOT safer than natural sun exposure. Tanning equipment usually emits higher levels of UV radiation than the UV radiation outside. Compared to the sun, sunlamps and tanning beds can emit up to 10 times more UVB radiation and on average 2 to 14 times more UVA radiation than the sun.

Yes, solar panels could get damaged by hailstones, especially if their sizes are greater than 2 inches. However, solar panels are designed and tested to endure severe hailstorms and other weather conditions that will not allow solar panels to break easily.

A sun allergy is a condition that happens when the immune system reacts to sunlight. The immune system treats sun-altered skin as foreign cells, leading to the reactions. The reactions that can occur include a rash, blisters or hives. Only people with sensitivity to the sun will exhibit symptoms.

Sunburn is a significant problem for potted aloes allowed to linger in a sunny window on hot summer days. White to tan lesions may form on the plant's leaves on the side exposed to the window. Outside aloes sometimes suffer from sunburn if they are still young or have been freshly transplanted to a new location.

Exposure to UV radiation—whether from the sun or from artificial sources such as sunlamps used in tanning beds—increases the risk of developing skin cancer, according to the National Cancer Institute (NCI). Melanoma, the deadliest form of skin cancer, is linked to getting severe sunburns, especially at a young age.

Sunbeds are sometimes marketed as a 'controlled way' of getting a 'safer tan'. But actually, sunbeds are no safer than exposure to the sun itself. One study found that the average skin cancer risk from sunbeds can be more than double that of spending the same length of time in the Mediterranean midday summer sun.

“The sun can be strong regardless of the season or temperature.” During winter, you're probably ready to hit the ski slopes. Beware: In high altitudes, UV rays are even more intense. Plus, the risk for sunburn is higher because the thinner atmosphere doesn't block as many of the sun's harmful rays.

Tanning beds expose you to UV rays, which can cause premature aging, sunspots, and even skin cancer. On the other hand, spray tans offer an instant glow without any of the dangerous exposure. Walk out of the studio with a beautiful bronzed body and peace of mind knowing that you're taking care of your skin and health.

Solar prominence If you put a steamy cup of coffee in the refrigerator, it wouldn't immediately turn cold. Likewise, if the sun simply "turned off" (which is actually physically impossible), the Earth would stay warm—at least compared with the space surrounding it—for a few million years.

Sunspots are flat brown spots that develop on areas of your skin that are exposed to the sun. They're also known as liver spots, though they have nothing to do with your liver. Sunspots are harmless.

Solar panels are also bad because countries using them are no longer so dependent on other states. Solar panels are subversive, because they encourage individualism and liberation from markets. Solar panels fragment social cohesion because their users dare to decentralise power generation. Don't buy solar panels.

The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.

It is the least explored of the three regions. Our Sun emits light at all the different wavelengths in electromagnetic spectrum, but it is ultraviolet waves that are responsible for causing our sunburns. To the left is an image of the Sun taken at an Extreme Ultraviolet wavelength - 171 Angstroms to be exact.
