What powers this unusual nebula? CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. The star likely detonated when it ran out of elements near its core that could create stabilizing pressure with nuclear fusion. The resulting supernova remnant, nicknamed the […]

What’s happening over the water? Pictured here is one of the better images yet recorded of a waterspout, a type of tornado that occurs over water. Waterspouts are spinning columns of rising moist air that typically form over warm water. Waterspouts can be as dangerous as tornadoes and can feature wind speeds over 200 kilometers […]

In visible light NGC 1333 is seen as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus, it lies at the edge of a large, star-forming molecular cloud. This Hubble Space Telescope close-up frames a region just over 1 light-year […]

Along a narrow path that mostly avoided landfall, the shadow of the New Moon raced across planet Earth’s southern hemisphere on April 20 to create a rare annular-total or hybrid solar eclipse. A mere 62 seconds of totality could be seen though, when the dark central lunar shadow just grazed the North West Cape, a […]

This view of the Antennae Galaxies, two large galaxies colliding 60 million light-years away, is one of the first research images from the Super Pressure Balloon Imaging Telescope (SuperBIT) that launched on a scientific super pressure balloon April 16, 2023 (local time New Zealand). via NASA https://ift.tt/0MGKm5x

Spanning light-years, this suggestive shape known as the Seahorse Nebula appears in silhouette against a rich, luminous background of stars. Seen toward the royal northern constellation of Cepheus, the dusty, obscuring clouds are part of a Milky Way molecular cloud some 1,200 light-years distant. It is also listed as Barnard 150 (B150), one of 182 […]

On some nights the sky is the best show in town. On this night, auroras ruled the sky, and the geomagnetic storm that created this colorful sky show originated from an increasingly active Sun. Surprisingly, since the approaching solar CME the day before had missed the Earth, it was not expected that this storm would […]
