Moon and Sun Over Wyoming

The Moon is seen passing in front of the Sun at the point of the maximum of the partial solar eclipse near Banner, Wyoming on Monday, Aug. 21, 2017. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe. Photo Credit: (NASA/Joel Kowsky) via NASA https://ift.tt/0bwCDny

Martian Barchan Dunes

This image shows two types of sand dunes on Mars. The small dots are called barchan dunes, and from their shape we can tell that they are upwind. The downwind dunes are long and linear. These two types of dune each show the wind direction in different ways: the barchans have a steep slope and crescent-shaped "horns" that point downwind, while the linear dunes are stretched out along the primary wind direction. Linear dunes, however, typically indicate a wind regime with at least two different prevailing winds, which stretch out the sand along their average direction. In several places in this image, you can find barchan dunes turning into linear dunes as they are stretched out, but they both seem into indicate the same wind direction. via NASA https://ift.tt/JUr0S58

Apollo 9 Astronaut David Scott’s Spacewalk

Excellent view of the docked Apollo 9 command and service modules (CSM) and lunar module (LM), with Earth in the background, during astronaut David R. Scott's stand-up spacewalk, on the fourth day of the Apollo 9 Earth-orbital mission. Scott, command module pilot, is standing in the open hatch of the command module. Astronaut Russell L. Schweickart, lunar module pilot, took this photograph of Scott from the porch of the LM. Inside the LM was astronaut James A. McDivitt, Apollo 9 commander. via NASA https://ift.tt/J05U8Ag

Women of NASA Langley Research Center

In honor of Women’s History Month 2024 and those who paved the way for them, hundreds of female staff – from artists to administrative support, educators to engineers, and scientists to safety officers – gathered in front of the Katherine G. Johnson Computational Research Facility at NASA’s Langley Research Center in Hampton, Virginia, on Feb. 6, 2024. via NASA https://ift.tt/ae03xCz

Hubble Uncovers a Celestial Fossil

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 Galaxy as our galaxy’s nearest galactic companion, but it is more accurate to say that Andromeda is the nearest galaxy that is not in orbit around the Milky Way galaxy. In fact, dozens of satellite galaxies orbit our galaxy and they are far closer than Andromeda. The largest and brightest of these is the LMC, which is easily visible to the unaided eye from the southern hemisphere under dark sky conditions away from light pollution. via NASA https://ift.tt/pun109z
