Stunning new Solar Orbiter images capture explosive activity on the sun
A new series of images from the Solar Orbiter spacecraft is giving scientists the clearest view yet of the sun's volatile lower atmosphere-and unlocking critical insights into the forces behind solar eruptions and space weather. On March 9, 2025, while nearly 48 million miles from the sun, the Solar Orbiter spacecraft was oriented to capture a sweeping view of the solar surface, the European Space Agency noted. Using a 5x5 grid, its Extreme Ultraviolet Imager (EUI) took six high-resolution images and two wide-angle views at each position. The result was a massive mosaic of 200 images, stitched together to create the widest high-resolution image of the Sun ever captured. "What you see is the Sun's million-degree hot atmosphere, called the corona, as it looks in ultraviolet light," the ESA explained. Astronomers say these images reveal the "middle zone" of the sun, between its stable surface and its erupting outer corona, where magnetic fields twist and plasma eruptions begin. The visible surface of the sun, called the photosphere, is about 10,000 degrees Fahrenheit, according to Strangely, the outermost layer of the sun's atmosphere-the corona-is much hotter, regularly reaching between 1.8 million and 3.6 million degrees. In some cases, it can spike as high as 72 million degrees, according to NASA. This superheated outer layer is made of plasma, a hot, electrically charged gas. It's also where powerful solar events like flares and eruptions begin. Scientists hope the data will eventually help explain why the sun's outer atmosphere is millions of degrees hotter than its surface-one of solar physics' biggest mysteries. The images come just as Solar Orbiter enters its closest pass of the sun to date. Solar Orbiter is a space mission of international collaboration between ESA and NASA. A team from University College London is using the data to better understand how solar storms develop. Understanding solar storms is key for improving space weather forecasting on Earth. The same activity that lights up the aurora can also interfere with satellites, GPS systems and power grids.

NASA shares new panoramic images revealing Mars' surface features
Listen to article NASA has released breathtaking panoramic images of Mars, offering an unprecedented view of the planet's diverse terrain. Captured by rovers and orbiters, the high-resolution images reveal rugged mountains, sweeping valleys, vast dunes, and evidence of ancient water flows on the Red Planet's surface. The newly released images provide a detailed and immersive perspective of Mars, giving scientists and space enthusiasts a chance to explore the planet like never before. The panoramas, stitched together from hundreds of individual images, highlight the dramatic variations in Mars' landscape, from cratered plains to towering cliffs and dusty plains. According to NASA's Jet Propulsion Laboratory (JPL), the images were captured using state-of-the-art cameras aboard rovers like Perseverance and Curiosity, as well as orbiters such as the Mars Reconnaissance Orbiter. "These stunning panoramas give us a new appreciation of Mars' geology and environmental history," said Dr. Lori Glaze, director of NASA's Planetary Science Division. "They help us understand how Mars evolved and where we should focus future exploration." Key Highlights from the Mars Panoramas The newly released images include: Jezero Crater: The landing site of Perseverance Rover, believed to be an ancient lakebed that once held water, possibly providing conditions for microbial life.

Gale Crater: Explored by the Curiosity Rover, this area features sedimentary layers that could hold clues about Mars' past climate. Why These Images Matter The panoramic views are not just for public fascination—they serve as critical data points for future missions. By studying rock formations, erosion patterns, and atmospheric conditions, scientists can determine potential landing sites for human missions and robotic exploration. The images also fuel NASA's long-term goals for Mars exploration, including the upcoming Mars Sample Return mission, which aims to bring Martian soil and rock samples back to Earth for in-depth study. Future Mars Exploration Plans NASA, in collaboration with international space agencies like ESA (European Space Agency), is working toward sending astronauts to Mars in the 2030s. The newly released images provide valuable insights for determining safe landing zones, identifying resource-rich locations, and understanding the planet's geological history. As Mars exploration continues, these images remind us of the vast and mysterious world beyond Earth, bringing us closer to answering one of humanity's biggest questions: Was Mars ever home to life?

Super Bowl Halftime Protester Gets Lifetime Ban After Gaza-Sudan Flag Stunt
A performer during Sunday night's Super Bowl halftime show unfurled a Palestinian and Sudanese flag and ran around the field before being tackled by security. The person was part of the 400-member field cast during Kendrick Lamar's performance but his demonstration was not part of the script, the NFL said in a statement to HuffPost. 'The individual hid the item on his possession and unveiled it late in the show,' the league said. 'No one involved with the production was aware of the individual's intent.' The man's flag had both countries' flags stitched together with 'Sudan' and 'Gaza' written across it. Roc Nation, which produced the show, also said that the act 'was neither planned nor part of the production and was never in any rehearsal.' The NFL said, 'The individual will (be) banned for life from all NFL stadiums and events.' The New Orleans Police Department said the man was ejected from the stadium without arrest or a court summons issued. The man first appeared waving the flag while standing on top of a car as the entertainers danced below him. He jumped off the vehicle and then the stage when a person with long hair appeared to approach him. Once on the field, he ran in circles waving the flag before being tackled and dragged off the green, video shows. Both Sudan and Palestine have been in turmoil, with Palestinians enduring an ongoing war between Israel and the military group Hamas, which has controlled the Gaza Strip since 2007. Sudan, meanwhile, has been locked in a civil war since the removal of its longtime autocratic President Omar al-Bashir in 2019.
