NASA APOD Features Barnard's Loop Glowing Over Twin Volcanoes

·1 views

NASA's Astronomy Picture of the Day (APOD) for July 28, 2026, showcases an image of Barnard's Loop set against a backdrop featuring twin volcanoes. APOD is a long-running NASA program that highlights a different astronomical image each day, accompanied by an explanation from a professional astronomer. Barnard's Loop is a large emission nebula located in the constellation Orion, faintly visible as a sweeping arc of glowing hydrogen gas. The featured image appears in both original and annotated versions, helping viewers identify key celestial features.

NASA to Live Stream Total Solar Eclipse Crossing Europe and Arctic in August

A total solar eclipse will occur on Wednesday, August 12, crossing parts of Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and a small section of Portugal. NASA plans to broadcast the event live, offering viewers coverage from multiple points along the eclipse's path. The stream will also feature interviews with scientific experts to provide context and insight into the phenomenon. NASA will make the coverage available across several online platforms for audiences worldwide.

Curiosity Rover Photographs 20-Foot Sand-Capped Martian Butte Named Miraflores

NASA's Curiosity Mars rover captured an image of a sand-topped rock formation on June 11, 2026, marking the 4,923rd Martian day of the mission. The feature, informally named 'Miraflores,' stands approximately 20 feet (6 meters) tall. The image was taken using the rover's Mast Camera, known as Mastcam. The butte formed as the softer rock surrounding it gradually eroded away, leaving the more resistant structure standing in a broad valley.

Curiosity Rover Finds Largest Concentration of Polygons on Mars Surface

NASA's Curiosity Mars rover captured a 360-degree panorama of a vast terrain covered in polygon-shaped surface features on June 19–20, 2026. The images were taken on the 4,930th and 4,931st Martian days, known as sols, of the mission. While Curiosity has previously encountered polygons on Mars, scientists noted this is the largest concentration of such formations the rover has ever observed in a single location. These geometric surface patterns are of scientific interest as they can indicate past freeze-thaw cycles or drying of ancient wet material.

NASA Curiosity Rover Spots Honeycomb-Like Rock Patterns on Mars

NASA's Curiosity rover has photographed a field of honeycomb-shaped geometric patterns while climbing a Martian valley known as 'Valle Grande.' The structures, called polygonal fractures, measure roughly 1.5 to 3 inches across. Mission scientists recognized the formations, having encountered smaller patches of similar shapes on previous occasions. The discovery adds to Curiosity's ongoing geological survey of the Martian surface.
