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 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.

Video Description: 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 a 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. If you liked this video, subscribe to the NASA.

There may not be any humans aboard NASA's #Artemis I flight test, but there will be a special canine: Snoopy! Learn why Astronaut Snoopy is flying to space when Artemis launches on its historic mission around the Moon and back. Artemis I is the first integrated flight test of the Space Launch System rocket that will send the uncrewed Orion spacecraft around the Moon and back to Earth. The mission will check out all spacecraft systems for the first time before crew fly aboard Artemis II. It's one more step toward taking the next giant leap: sending the first astronauts to Mars. Get all the info on this historic mission.

Science Launching on Northrop Grumman's CRS-18 Mission to the Space Station The 18th Northrop Grumman commercial resupply services mission to the International Space Station carries scientific investigations of topics such as 3D printing of knee cartilage, plant mutations, and mudflow structure—along with a demonstration of camera technology and small satellites from Japan, Uganda, and Zimbabwe. The Cygnus spacecraft carrying these investigations to the orbiting laboratory is scheduled for liftoff no earlier than Nov. 6, 2022, from the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility on Wallops Island, Virginia. Learn more about some of the scientific research traveling to the station on this.

After months aboard the International Space Station, the astronauts of NASA’s SpaceX Crew-4 mission are returning home. Traveling back to Earth inside a SpaceX Dragon capsule are NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, along with ESA (European Space Agency) astronaut Samantha Cristoforetti. During their time aboard the orbiting laboratory, these crew members contributed to ongoing and new scientific investigations and technology demonstrations, work that is helping to prepare humans for future space exploration missions and generating innovations and benefits for humanity on Earth.

We’re testing a new way of landing on Mars… by crashing into its surface. The Simplified High Impact Energy Landing Device (SHIELD) is a lander concept being tested at NASA’s Jet Propulsion Laboratory (JPL). It could one day provide a new way for low-cost missions to land on Mars. Rather than rely on parachutes or retrorockets, SHIELD would include a collapsible, accordion-like base to absorb the energy of a landing. A full-size prototype of the base was tested on Aug. 12, 2022. The prototype was hurled at the ground from the top of a nearly 90-foot-tall (27-meter-tall) drop tower at JPL. A steel plate ensured the impact was even harder than what would be experienced on Mars. The design worked: After crushing against the steel plate at 110 mph (177 kph), several electronic components inside the SHIELD prototype, including a smartphone, survived the impact.

NASA Explorers Season 5, Episode 4: The South Pole When Artemis astronauts land on the Moon, they’ll travel to sites never before visited by humans. Namely, they'll explore the South Pole region, home to the Moon’s largest crater, areas of near-constant light and deep shadows, and some of the coldest temperatures in the solar system. Exploring the South Pole will teach us more about the Moon’s history, as well as the history of our solar system. It's home to frozen water, which is crucial for living sustainably on the lunar surface and exploring deeper into the solar system. Artemis astronauts will explore the Moon on behalf of all of us and bring back lunar rocks and soil for analyses by generations of scientists who will help us gain unimaginable insights into our cosmic history.

An image from NASA’s James Webb Space Telescope reveals a remarkable sight: at least 17 concentric dust rings emanating from a pair of stars located about 5,300 light-years from Earth. Each ring was created when the stars came close together, and their colliding stellar winds (streams of gas they blow into space) caused some of the gas to compress into dust. Collectively known as Wolf-Rayet 140, the stars’ orbits bring them together about once every eight years, so just like the growth rings of a tree trunk, these dusty loops mark the passage of time: The 17 rings reveal more than a century of stellar interactions. And while other Wolf-Rayet stars produce dust, no other pair is known to produce rings quite like Wolf-Rayet 140. Because the stars’ orbits are elliptical rather than circular, the distance between the stars changes constantly, and dust forms only when they are close. The amount of dust produced by this interaction varies, so the system doesn’t form a perfect bullseye. One of the densest regions of dust production creates the bright feature repeating at 2 o’clock.

NASA Moon Phases 2022 – Northern Hemisphere – 4K

In this video, measurements collected by the Waves instrument aboard NASA’s Juno spacecraft during its close flyby of Jupiter’s moon Europa on Sept. 29, 2022, have been converted to an audible frequency. As the white line moves across the spectrogram, which is a visual way of representing signal strength over time, the variation of frequency of the plasma waves observed near Europa can be heard as the plasma density varies. The video shows data collected over approximately 1.5 hours during the Europa flyby.

Take in a unique 360-degree view of NASA’s Space Launch System rocket and Orion spacecraft – from high up in Kennedy Space Center’s Vehicle Assembly Building – as it begins its rollout to Launch Complex 39B. Targeted for launch no earlier than Aug. 29, Artemis I will mark the first integrated test of the SLS and Orion.
