A new study, published in the Proceedings of the National Academy of Sciences suggests that exposure to ultraviolet (UV) rays in the morning hours may be less harmful than the sun´s ray´s in the afternoon. The study, performed on mice because they have a similar circadian rhythm to humans only opposite, found that mice exposed to UV radiation at 4 am had a 500 percent increase in the incidence of skin cancer than those exposed to UV radiation at 4pm. Since the 24 hour...

Spacecraft Helps Discover Ozone Layer On Venus
2011-10-06 09:31:01

[ Watch the Video ] The European Space Agency's Venus Express spacecraft has discovered an ozone layer in the atmosphere of Venus. The spacecraft made the discovery while watching stars from the edge of the planet seen through its atmosphere. SPICAV, an instrument aboard Venus Express, analyzed the starlight and found characteristic fingerprints of gases in the atmosphere as they absorbed light. ESA said the ozone was detectable because it absorbed some of the ultraviolet from the...

Incoming Solar Radiation Impacts By Various Weather Cycles
2012-08-22 13:30:39

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...
