HONOLULU — Snow fell on Hawaii’s tallest peak this week, briefly turning the mountaintop into a winter wonderland. The summit area of Mauna Kea on the Big Island got about 2 inches of white powder. But it’s not unusual for snow to fall at the higher elevations on Mauna Kea during the wetter, winter months. “Combination of cold temperatures and moisture equals snow when it’s below freezing,” Ballard said. Centuries-old stories say Mauna Kea is the first-born son of the sky father and earth mother.

But it could be explained by magnetic fields — fields that were, in fact, found to be so strong that it was determined to be the most magnetic massive star ever recorded. It even gave rise to a new definition: a “massive magnetic helium star.”Now, scientists suspect that one day, the star will collapse in a supernova explosion. But it’s a massive step forward in unlocking the mysteries of magnetars, which have confounded scientists for decades. The mysteries of a magnetic starThe massive magnetic helium star at the heart of the study is part of a two-star system called HD 45166. Scientists already knew that about 10% of neutron stars are also magnetars.

CNN —A Jupiter-like planet located 520 light-years from Earth may be an unlikely survivor after its host star had a temper tantrum. The gas planet is known as 8 UMi b and was named Halla after its initial discovery by Korean astronomers in 2015. The exoplanet orbits a giant star larger than our sun named Baekdu, located in the Ursa Minor, or “Little Bear,” constellation. Halla orbits Baekdu at a distance about half that between the Earth and the sun at 0.46 astronomical units, or 42,759,659 miles (68,815,020 kilometers). While our solar system only has one star, many stars across the universe exist in binary pairs.

A supernova has exploded in the Pinwheel Galaxy 21 million light-years away. Named SN 2023ixf, it sets itself apart by being one of the brightest seen in a decade. The supernova, which appeared in the Pinwheel Galaxy 21 million light-years away, is one of the biggest and brightest in our skies in a decade, Space.com reported. But this supernova, named SN 2023ixf, sets itself apart by its proximity to Earth: it's located in the Pinwheel Galaxy, which is only about 21 million light-years away. The Pinwheel Galaxy is located close to two of the stars in the handle of the Big Dipper.

CNN —A sparkling new supernova has appeared in the night sky, and a telescope atop Mauna Kea in Hawaii was perfectly poised to capture the aftermath of the cosmic burst. The supernova was first spotted within the spiral arms of the Pinwheel Galaxy by Japanese astronomer Koichi Itagaki on May 19. The Pinwheel Galaxy is in the direction of the Ursa Major constellation, about 21 million light-years from Earth. The new supernova glimmers bright blue in one of the galaxy’s spiral arms in the bottom left of the image. It’s the second supernova observed in the Pinwheel Galaxy in 15 years.
