What’s happening across that field? Pictured here are not auroras but nearby light pillars, a phenomenon typically much closer. In most places on Earth, a lucky viewer can see a Sun pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually, […]
How would you feel if the Sun disappeared? Many eclipse watchers across the USA surprised themselves in 2017 with the awe that they felt and the exclamations that they made as the Sun momentarily disappeared behind the Moon. Perhaps expecting just a brief moment of dusk, the spectacle of unusually rapid darkness, breathtakingly bright glowing […]
Methalox rocket engine firing, Odysseus’ landing legs absorb first contact with the lunar surface in this wide-angle snapshot from a camera on board the robotic Intuitive Machines Nova-C moon lander. Following the landing on February 22, broken landing legs, visible in the image, ultimately left the lander at rest but tilted. Odysseus’ gentle lean into […]
This densely populated group of stars is the globular cluster NGC 1841, which is part of the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way galaxy that lies about 162,000 light-years away. Satellite galaxies are bound by gravity in orbits around a more massive host galaxy. We typically think of the Andromeda […]
Murriyang, the CSIRO’s Parkes radio telescope points toward a nearly Full Moon in this image from New South Wales, Australia, planet Earth. Bathed in moonlight, the 64 meter dish is receiving weak radio signals from Odysseus, following the robotic lander’s February 22 touch down some 300 kilometers north of the Moon’s south pole. The landing […]
Following a launch on Feb. 15, Intuitive Machines’ Odysseus lander touched down in the Moon’s south polar region on Feb. 22 and has since transmitted valuable scientific data back to Earth. via NASA https://ift.tt/chQM5Jq
In 46 BC Julius Caesar reformed the calendar system. Based on advice by astronomer Sosigenes of Alexandria, the Julian calendar included one leap day every four years to account for the fact that an Earth year is slightly more than 365 days long. In modern terms, the time it takes for the planet to orbit […]
“Anyone you see on the streets, their color or background doesn’t matter; we all come into this world the same way. You’re equipped with skills, so find your passion and go for it.” – Dr. Charles Gatebe, Chief of Atmospheric Science Branch, NASA’s Ames Research Center via NASA https://ift.tt/Dfitlce
How does the sky turn dark at night? In stages, and with different characteristic colors rising from the horizon. The featured image shows, left to right, increasingly late twilight times after sunset in 20 different vertical bands. The picture was taken last month in Syracuse, Sicily, Italy, in the direction opposite the Sun. On the […]
A female (left) and a male roseate spoonbill get together near the tall grasses at the edge of a pond in the Merritt Island National Wildlife Refuge, northwest of Kennedy Space Center in Florida. Spoonbills inhabit areas of mangrove such as on the coasts of southern Florida and Texas. These birds feed on shrimps and […]
