Chance Triple Alignment: Plane, Space Station, SunThis shot captured an unexpected silhouette. Which is it? It isn’t the sunspots, the small dark regions caused by concentrated magnetic fields visible around the Sun’s bright disk. Sunspots typically last for weeks and were expected, since these spots were seen previously. It isn’t the I…Read More

Chasing the Moon’s ShadowChasing the shadow of a New Moon, NASA’s WB-57F high altitude research aircraft took to the skies off the coast of Iceland on August 12 to observe a total solar eclipse. At 50,000 feet the aircraft was piloted along the precisely determined path of totality to maximize its time in the Moon’s shadow. A suite of hig…Read More

Launch of the Roman Space TelescopeA new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST’s main mirror is more curved, its…Read More

M74: A Grand Design SpiralIf not the most grand, then this spiral galaxy is at least one of the most photogenic. An island universe of about 100 billion stars, 32 million light-years away toward the constellation Pisces, M74 presents a gorgeous face-on view. Classified as an Sc galaxy, the grand design of M74’s graceful spiral arms are traced by…Read More

Eclipse Pairclipses tend to come in pairs. Twice a year, during an eclipse season that lasts about 34 days, Sun, Moon, and Earth can nearly align. Then the new and full phases of the Moon, separated by just over 14 days, create a solar and a lunar eclipse. But only rarely is the alignment at both new moon and full moon during a single eclipse…Read More
