Dense bands of dust streamed offshore from southern Morocco in summer 2024. The VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite acquired this image of a plume of Saharan dust as winds lofted it over the Atlantic Ocean on Aug. 24, 2024. via NASA https://ift.tt/izYHECe

A nearby star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1.5 degree wide field-of-view would span about 150 light-years. In the sharp color composite image faint details of the region’s gas and dust clouds are highlighted with narrowband image data against a backdrop […]

When can you see a black hole, a tulip, and a swan all at once? At night — if the timing is right, and if your telescope is pointed in the right direction. The complex and beautiful Tulip Nebula blossoms about 8,000 light-years away toward the constellation of Cygnus the Swan. Ultraviolet radiation from young […]

What if Saturn disappeared? Sometimes, it does. It doesn’t really go away, though, it just disappears from view when our Moon moves in front. Such a Saturnian eclipse, more formally called an occultation, was visible along a long swath of Earth — from Peru, across the Atlantic Ocean, to Italy — only a few days […]

When this picture was taken in July 1994, Dr. Irene Duhart Long was director of the Biomedical Operations and Research Office at NASA’s Kennedy Space Center in Florida. She was responsible for the program management of the center’s aerospace and occupational medicine, life sciences research, environmental health programs, and the operations management of the life […]

Did you see it? One of the more common questions during a meteor shower occurs because the time it takes for a meteor to flash is similar to the time it takes for a head to turn. Possibly, though, the glory of seeing bright meteors shoot across the sky — while knowing that they were […]

Do underground oceans vent through canyons on Saturn’s moon Enceladus? Long features dubbed tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s South Pole and creating Saturn’s mysterious E-ring. Evidence for this has come from the robot Cassini spacecraft […]

The full Moon and Earth’s shadow set together in this island skyscape. The alluring scene was captured Tuesday morning, August 20, from Fiji, South Pacific Ocean, planet Earth. For early morning risers shadowset in the western sky is a daily apparition. Still, the grey-blue shadow is often overlooked in favor of a brighter eastern horizon. […]
