Solar Orbiter spacecraft obtains first images of the sun's poles
The European Space Agency on Wednesday released images taken in March using three of Solar Orbiter's onboard instruments. They show the sun's south pole from a distance of roughly 40 million miles (65 million km), obtained at a period of maximum solar activity. Images of the north pole are still being transmitted by the spacecraft back to Earth.
Solar Orbiter, developed by ESA in collaboration with the U.S. space agency NASA, was launched in 2020 from Florida.
Until now, all the views of the sun have come from the same vantage point - looking face-on toward its equator from the plane on which Earth and most of the solar system's other planets orbit, called the ecliptic plane.
Solar Orbiter used a slingshot flyby around Venus in February to get out of this plane to view the sun from up to 17 degrees below the solar equator. Future slingshot flybys will provide an even better view, at beyond 30 degrees.
"The best is still to come. What we have seen is just a first quick peek," said solar physicist Sami Solanki of the Max Planck Institute for Solar System Research in Germany, who heads the scientific team for the spacecraft's Polarimetric and Helioseismic Imager instrument. Reuters

Mystery light over U.S. East Coast sparks UFO speculation online
Ammon News - A mysterious spiraling light spotted in the night sky over the eastern United States sparked UFO speculation online, but was likely the result of a rocket launch. Witnesses reported seeing the ball of light, which appeared to have a spiral shape around it, in the Tuesday night sky over New Jersey, Pennsylvania and Connecticut, with some reports indicating it was seen as far west as Ohio. Photos and videos of the light sparked speculation online, with some suggesting it could be a sign of extraterrestrial visitors. Others pointed out, however, that the timing of the light coincided with the United Launch Alliance's Vulcan Centaur rocket, which took off shortly before 9 p.m. Tuesday in Cape Canaveral, Fla. The rocket was carrying an an experimental navigation satellite into orbit for the U.S. military. A second rocket was also launched around the same time in Africa. UPI

Pictures of 'zombie-rabbits' with twisting black horns go viral
Ammon News - Photos of rabbits in Colorado with black, horn-like growths around their faces have gone viral, with some describing the animals as "Frankenstein-", "zombie-" and "demon-rabbits". Residents in Fort Collins near Denver recently began posting pictures of the cottontail bunnies, causing a stir online. "This is how the zombie virus starts," posted one Instagram user on a post showing the rabbits. "We've got freaking zombie rabbits now?!" posted another on YouTube. So what's going on? Firstly, the pictures are real - despite some wishing they weren't. "One time I need this to be AI," wrote one Instagram user on a post showing the horned bunnies. The rabbits are suffering from a relatively harmless disease called Shope Papilloma Virus, according to Colorado Parks and Wildlife. Although the wildlife agency is getting calls from people spotting the infected rabbits in Fort Collins, they're not an unusual sight, according to spokesperson Kara Van Hoose. The disease is mainly found in America's Midwest, according to the University of Missouri, and is more noticeable in the summer, when the fleas and ticks that spread the virus are most active. The virus can also spread through rabbit-to-rabbit contact but not to other species like humans or dogs and cats, according to Ms Van Hoose.

Auction of world's largest Mars meteorite sparks ownership debate
Ammon News - The recent auction of a Martian meteorite for a record-grabbing $5.3 million at Sotheby's New York has sparked questions over its provenance and renewed debate over who gets to claim rocks fallen from the heavens. The hefty 54-pound (25-kilogram) stone is the largest Martian meteorite ever discovered on Earth, according to its Sotheby's listing, and was found in November 2023 in the vast Saharan desert in Niger. The government of Niger has announced that it will open an investigation following the auction, saying it appears to "have all the characteristics of illicit international trafficking." On Friday, the government suspended exports of precious stones and meteorites until further notice. Sotheby's has rejected the accusations, insisting that the meteorite was "was exported from Niger and transported in line with all relevant international procedure." In light of the controversy, however, a review of the case is underway, a Sotheby's spokesperson told AFP. "The stone journeyed 140 million miles through space, and hurtled through Earth's atmosphere before crashing in the Sahara Desert," the Sotheby's listing said. Following its discovery, the jagged, ochre-colored stone was then sold to an international dealer, briefly exhibited in Italy, and eventually ended up in the auction catalog in New York. For American paleontologist Paul Sereno, who has worked closely with Niger's authorities for years, all signs suggest that the stone left the country "illicitly." "Everybody's anonymous from the person who found it, the dealers, the guy who bought it, everybody's anonymous," he told AFP, making no secret of his frustration. AFP
