On August 21, 2017, a total solar eclipse was viewed in the United States from Oregon to South Carolina. People who were able to view the eclipse in the path of totality were treated to total darkness for 2.5 minutes. Some viewing areas played music, and shot fireworks into the darkness. For people who were not able to travel to the path of totality, were still treated to a partial eclipse. The top-left image was taken in Manassas, Virginia during the first part of the eclipse. Shortly after the picture was taken, storm clouds rolled in and the peak of the eclipse was not able to be seen. The other three pictures were taken in Fredericksburg, Virginia. The bottom-left picture is the result of the eclipse shown through the leaves of the trees. The top-left was taken by an iPhone with a sun filter used for a telescope. The box-shape with three holes showing the eclipse (top-right) is the result of the bottom-right contraption. If you didn’t have glasses, sun filters, or the items to make a contraption, people also used their hands to project the eclipse on the sidewalk (also, top-right). Traffic conditions were very heavy while travelers were trying to make it to the path of totality. Many news stations including NASA and The Weather Channel streamed the eclipse live in different locations as to show the entire path from the West Coast to the East Coast. If you were not able to make this eclipse, don’t worry as there will be another total solar eclipse in April of 2024 spanning from Texas to Maine.

Tomorrow, August 21, 2017, 14 states will experience a total solar eclipse. A total solar eclipse is when the Moon crosses in between the Earth and the Sun. For people who are in the path of totality, the Moon will completely cover the Sun. People who are not in the path of totality will only experience a partial solar eclipse, meaning that the sun will not be completely covered. When viewing this amazing event, people need to be ready as to not damage their eyes. NASA, along with several other retailers, have been selling special glasses that can only be used for viewing the eclipse. Regular sunglasses are not safe to wear during the eclipse because they do not filter the sunlight. If you do not have these special glasses, you can project an image of the sun onto a screen using a cereal box. Click here for more safe ways to view the eclipse! When obtaining these glasses, be sure they come with the ISO 12312-2 safety standard. People have expressed concern for their pets, however, animals do not look at the sun. Large crowds are expected in and near the path of totality so traffic is expected to be very heavy during the time of the eclipse. The eclipse will start around 9:00 AM PDT in Oregon, and end at 1:13 PM EDT in South Carolina. Schools have either closed or have extended the school day so students can view this historical event. Make sure you are safe and ready for the historical event, as the next eclipse for the United States is in 2024. However, the eclipse in 2024 will stretch from Texas to Maine.

DISCUSSION: Although many people are predominantly focused on weather and trends therein here on planet Earth, there are also other larger planets to consider within our solar system here in the Milky Way galaxy! In looking to other planets including ( but certainly not limited to) Saturn, many people tend to forget that storm systems form on other planets besides planet Earth. Moreover, in many cases, storm systems and associated convection often can tend to last much longer than typical convective storms which we observe and study here on Earth. In the case of Saturn, our satellite technology has gotten so sophisticated that astronomical research scientists now have the ability to detect lightning emanating from convective storm via radio wave signals. An example of this radio signal convective storm detection capability is captured in the video attached above. Note how faint the signals are and this is directly tied to the fact that Saturn is positioned so far from planet Earth within our solar system. Just another way that advanced space-based satellite technology has revolutionized the way in which we now study outer space and other planets therein.

DISCUSSION: As we get closer and closer to the day on which the all-expected national solar eclipse will occur, many people across the nation are starting to and/or continuing to ask some similar (but relevant) questions. For starters, many people have asked whether or not the likelihood of clouds is higher or lower for Monday, August 21st. This would slight impact the likelihood of whether people in a given region will be able to clearly see the evolution of the total solar eclipse (i.e., whether they happen to lie within the path of totality of not).
An increase in cloudiness may not necessarily guarantee that any given town or city would not be able to see the evolution of the total solar eclipse, but rather that the full effect of the solar eclipse may end up being somewhat obscured by any variable degree of cloudiness (whether it be at the lower-, middle-, or upper-levels). Thus, it will certainly be quite interesting to see how the national forecast evolves for the upcoming eclipse and how it will affect the national ability to visualize the eclipse as it travels across the country.

Discussion: Earth experiences storms every day, be it in the form of hurricanes, tornadoes, or thunderstorms. Other planets in the solar system experience storms as well, albeit in slightly different forms. Previous articles have gone into detail about storms on Venus, Jupiter, and Saturn. Now, we will turn our focus onto the dark-blue plant Neptune and its Great Dark Spot. The Great Dark Spot, first discovered by Voyager 2 in 1989, was similar to Jupiter’s Great Red spot in appearance as well as the fact that they were anticyclonic storms. Though, the Great Dark Spot had a surprising lack of clouds.
The Great Dark Spot was roughly 8,100 miles by 4,100 miles in size, roughly the size of the Earth, though it did appear to change size shape over time. Winds in the Great Dark Spot were measured at an astounding 1,500 miles per hour, easily the fastest in the solar system. Large white clouds, similar to cirrus clouds in Earth’s atmosphere appeared in the storm, and unlike Earth’s cirrus clouds which only last a few hour, the clouds in the Great Dark Spot could persist for 36 hours. When the Great Dark Spot was photographed again by the Hubble Telescope in 1994, the spot had disappeared, making scientists wonder if it had disappeared and why. Upon further investigation, a very similar dark spot was found in Neptune’s Northern Hemisphere and has remained visible for years, though due to the Hubble Telescope’s limitation, it is uncertain if it still exists. It is believed that dark spots are stable features that can persist for several months, are thought to be vortex features, and former dark spots may continue to exist as cyclones even if they are no longer visible as dark spots.
