This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA's Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun's outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes asmagnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe. The music is a continuous mix from Lars Leonhard's "Geometric Shapes" album, courtesy of the artist.

What are Black Hole: How Do Black Holes Form? Black holes are like cosmic vacuum cleaners that suck everything in, even light! But how do they come to be? Join us on a visual adventure where we break down the science step by step .Imagine a gigantic star that's burning brightly. Over time, it runs out of fuel and collapses under its own weight. This collapse is so intense that it forms a black hole. We'll show you how this process works and why it's so mind-blowing. Black holes are like bends in the fabric of the universe. They create a sort of 'hole' in space called an event horizon. Anything that crosses this boundary gets trapped forever! Wrap your head around this mind-bending concept with our simple explanations. But don't worry, you don't need a rocket scientist degree to get this! We'll break down complex ideas into easy words and fun visuals, so you'll have a blast learning about these cosmic enigmas. Join the Space Chat We're not just here to talk at you-we want to hear your thoughts too! Drop your questions and ideas in the comments section, and let's explore the universe's mysteries together.
