In the vast expanse of the cosmos, where stars shimmer and galaxies collide, lies a tapestry of mysteries waiting to be unraveled. Get ready to be captivated by the wonders and the biggest mysteries that lie beyond our reach, awaiting discovery in the depths of the universe in this 4K space documentary. Topics covered- 1. Olber’s Paradox (Why is space black?) 2. First Contact 3. Vanishing of Planet Dagon (Fomalhaut b) 4. Pioneer Anomaly

A world first. New footage from Mars rendered in stunning 4K resolution. We also talk about the cameras on board the Martian rovers and how we made the video. A question often asked is: ‘Why don’t we actually have live video from Mars?’ Although the cameras are high quality, the rate at which the rovers can send data back to earth is the biggest challenge. Curiosity can only send data directly back to earth at 32 kilo-bits per second. Instead, when the rover can connect to the Mars Reconnaissance Orbiter, we get more favourable speeds of 2 Megabytes per second. However, this link is only available for about 8 minutes each Sol, or Martian day. As you would expect, sending HD video at these speeds would take a long long time. As nothing really moves on Mars, it makes more sense to take and send back images.

The International Space Station is the largest man made object in space. It was built in pieces and then launched into space and assembled in orbit. This video explains each interior area, crew living quarters and scientific equipment. If you want more information like this please stay connected to my channel.

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 4Kx 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 as magnetic 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. On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time lapse. There are usually only a few bright regions visible at time and they shift and flash like small fires. From these regions there are wispy loops reaching up above the surface that rapidly change shape and size. On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun. Please Like And Share This Video
