This image taken by the Mars Reconnaissance Orbiter spacecraft’s HIRISE instrument on Oct. 23, 2022, of the northern plains of Arabia Terra shows craters that contain curious deposits with mysterious shapes and distribution. For instance, the deposits are located on the south sides of the craters, but not usually in the north, and are found only in craters l...
The James Webb Space Telescope spies the spiral galaxy NGC 7469, located 220 million light-years from Earth in the constellation Pegasus, in this image released on Dec. 21, 2022. This galaxy is very dusty, but Webb’s infrared vision can peer through to observe features like the intense ring of star formation close around its bright center. Download the full-...
On Dec. 24, 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders became the first humans to orbit the Moon, and the first to witness the magnificent sight called “Earthrise.” As the spacecraft was in the process of rotating, Anders took this iconic picture showing Earth rising over the Moon’s horizon. In 2018, the International Ast...
Dec. 22, 2022 — Expedition 68 Flight Engineer and NASA spacewalker Josh Cassada prepares a roll-out solar array for its deployment on the International Space Station’s (ISS) Port-4 truss segment as the orbiting lab flew 262 miles above the Atlantic Ocean off the coast of Namibia. Astronauts Frank Rubio and Josh Cassada conducted a spacewalk on Th...
Hawaii’s big island and its two major volcanoes Mauna Kea and Mauna Loa rest under a partly cloudy sky on Feb. 8, 2022, in this view from the International Space Station. Mauna Loa, the world’s largest active volcano had been quiet for nearly 40 years. However, in 2022, the volcano began to stir, showing increased numbers of small earthquakes and subtl...
By taking a closer look at one of Webb’s first images, the iconic Cosmic Cliffs, scientists have found dozens of energetic jets and outflows from young stars previously hidden by dust clouds. The discovery marks the beginning of a new era of investigating how stars like our Sun form, and how the radiation from nearby massive stars might affect the developmen...
On Dec. 18, 2022, InSight did not respond to communications from Earth. As expected, the lander’s power has been declining for months, and it’s assumed InSight may have reached its end of operations. NASA will declare the mission over when InSight misses two consecutive communication sessions with the spacecraft orbiting Mars, part of the Mars Relay Network ...
NASA is taking a leading role to help integrate new types of Advanced Air Mobility aircraft like air taxis and delivery drones into the sky, helping emerging markets to safely develop an air transportation system that moves people and cargo between places previously not served or underserved by aviation. NASA is working with private sector developers of elec...
A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of...
Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly. NGC 6956 is a barred spiral galaxy, a common type of spiral galaxy with a bar-shaped structure of stars in its center. This galaxy exists 214 million light-years away in the constellation Delphinus. Scientists used NASA’s Hubble Space Telescope to image NGC 6956 to...
