How NASA Uses and Improves Solar Power?The Sun is the most energetic object in our solar system.Humans have been finding creative ways to harness the Sun's heat and light for thousands of years. But the practice of converting the Sun’s energy into electricity — what we now call solar power — is less than 200 years old. Yet in that short time, solar power has revealed the Sun’s limitless potential to power an increasingly technological society. Since the 1950s, NASA has harnessed the energy of the Sun to power spacecraft and drive scientific discovery across our solar system. Today, NASA continues to advance solar panel technology and test new innovations.https://www.youtube.com/watch?v=HHA3DwXNhjcVideo credit: NASA's Goddard Space Flight Center/Lacey YoungA Brief History of Solar Power:https://science.nasa.gov/wp-content/uploads/2024/09/standard-compressed-alexandre-edmond-becquerel-e1727186117653.jpgPic: A portrait of French scientist Alexandre Edmond Becquerel, taken sometime in the mid-1800s. (Public Domain)Even before the light bulb, scientists had inklings of the power locked up in a ray of sunlight.In 1839, French scientist Alexandre Edmond Becquerel (who was 19 at the time) was working in his father’s laboratory, experimenting with two metal sheets placed in an electricity-conducting liquid. As he shined light on the device, he detected a weak electric current — what we now know to be a flow of electrons through the material. This phenomenon was the first demonstration that light could generate electricity, known today as the photovoltaic effect.So how Solar Panels Work?Silicon is an abundant material used in many technological applications because it is a very good “semiconductor, ” or material whose ability to carry electric current can be easily manipulated by adding energy. In typical solar cells, silicon is layered in three thin sheets. A middle layer is made of pure silicon. The outer two silicon layers are injected with other elements (typically phosphorous on one side, and boron on the other) that differ in their capacity to “donate” or “accept” electrons. As light strikes the pure silicon layer, it energizes the silicon’s electrons, which then begin to move within the material. Those electrons are attracted to the silicon layer designed to “accept” electrons, leading to a buildup of negative and positive charges in the outer layers. These two sides are then connected with wires to form a circuit that facilitates the flow of electrons from one side to the other, generating usable power.Silicon-based solar cells power many of NASA’s spacecraft, including the James Webb Space Telescope.

Solar panels today use this same basic design, with adjustments that have allowed industrial and commercial solar panels to achieve between 15% and 23% efficiency.

Monet and the Sea: Exploring His Timeless Connection with the Ocean. Claude Monet, the master of Impressionism, had an enduring fascination with the sea. From tranquil harbors to crashing waves, his depictions of the ocean remain some of the most beloved and evocative works in art history. Monet’s relationship with the sea was not just about capturing its beauty but also its ever-changing moods, light, and colors—a reflection of his innovative approach to painting. The Sea as a Muse Watch the Monet and the sea Fine art Classical Paintings Video https://youtu.be/oIDKMOVf_RI?si=CjJu10vFsmqWIdMw For Monet, the sea was more than a subject; it was a source of inspiration. He often found himself drawn to coastal landscapes, spending significant time in locations like Étretat, Trouville, and Dieppe in France. These settings offered Monet the perfect environment to explore the interplay between water, sky, and light. His paintings reflect not only the sea’s power and vastness but also its subtleties, such as the way sunlight dances on its surface or how fog gently veils its horizon. Capturing Movement and Light https://vitruvius.museumseven.com/render/600-600@1/dp-265247-22.jpg Monet’s sea paintings stand out for their ability to capture the fleeting moments of nature. Whether it was the gentle ripples of a calm sea or the thunderous crash of waves against rocky cliffs, Monet’s brushstrokes brought these scenes to life. His iconic works, such as The Cliff Walk at Pourville or Fishing Boats Leaving the Harbor at Le Havre, reveal his mastery in depicting the dynamic relationship between water and light. Using his signature Impressionist style, Monet painted en plein air, immersing himself in the natural environment to observe and translate its essence onto the canvas. His ability to convey the movement and ephemeral qualities of the sea set him apart, making his maritime works timeless masterpieces. The Emotional Resonance of the Ocean Monet’s sea paintings evoke a spectrum of emotions, from the serenity of a peaceful shoreline to the awe inspired by a stormy seascape. These works resonate with viewers because they go beyond mere representation—they capture the soul of the ocean. For Monet, the sea was a metaphor for freedom, creativity, and the unpredictable nature of life itself. Legacy of Monet’s Maritime Masterpieces Monet’s connection with the sea influenced generations of artists who sought to portray nature in new and innovative ways. His maritime works continue to inspire not only art enthusiasts but also anyone who feels a connection to the natural world. They remind us of the ocean’s beauty, power, and the endless fascination it holds.
