In this image from April 10, 2022, sunlight glints off the Atlantic Ocean in this photograph from taken by the crew of the International Space Station as it orbited 262 miles above. Every 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. Learn More International Space Station Facts and Figures Image Credit: NASA...
NASA and the National Park Service worked together to create a web-based tool that helps park managers better understand the impact of outdoor lighting and noise on animal species in national parks. The website allows park managers to choose a time period, such as the spring or winter seasons, and then zoom into a particular park to see sound and nighttime l...
Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial “missing link” between young star-forming galaxies and the first supermassive black holes, using data from the Hubble Space Telescope to make this discovery. This artist’s impression is of a supermassive black hole that is inside the ...
What looks like a red butterfly in space is in reality a nursery for hundreds of baby stars, revealed in this infrared image from NASA’s Spitzer Space Telescope. Officially named W40, the butterfly is a nebula – a giant cloud of gas and dust in space where new stars may form. The butterfly’s “wings” are giant bubbles of hot, interstel...
In the early morning hours of April 12, 1981, NASA launched is first Space Transportation System, or space shuttle, mission, carrying astronauts John Young and Robert Crippen into orbit. Mission Commander John Youn had already flown in space four times, including a walk on the Moon in 1972. Bob Crippen, the pilot, was a Navy test pilot who would go on to com...
A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in this image from the Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143. The pair contains the glittery, distorted, star-forming spiral galaxy NGC 2445 at right, along with its less flashy companion, NGC...
Axiom Mission 1 (Ax-1) is in the foreground on Launch Pad 39A with NASA’s Artemis I in the background on Launch Pad 39B on April 6, 2022. This is the first time two totally different types of rockets and spacecraft designed to carry humans are on the sister pads at the same time—but it won’t be the last as NASA’s Kennedy Space Center in Florida continues to ...
Japan’s Geiyo Archipelago, in the Seito Inland Sea, was once home to pirates. From the 9th to the 16th centuries, the pirates dominated the Inland Sea and terrorized the coasts of East Asia. Until the Shimanami Kaido (Inland Wave Sea Road) was completed in 1999, the Geiyo Islands were a remote region, accessible only by boat. This ASTER image was acqui...
NASA and industry partners are working towards a future that sees aviation meet cleaner sustainability standards. To that end, new designs for the airplanes of tomorrow, such as the Transonic Truss-Braced Wing (TTBW) concept shown in this image from 2021, are being tested by researchers and engineers. The TTBW is essentially a classic tube-and-wing passenger...
Every winter, a layer of carbon dioxide frost (dry ice) forms on the surface of Mars. At its greatest extent in mid-winter, this frost reaches from the poles down to the middle latitudes, until it is too warm and sunny to persist. In most places this is around 50 degrees latitude, similar to the latitude of southern Canada on Earth. However, small patches of...
