Best of 2024: Total Solar Eclipse in Indianapolis
A total solar eclipse is seen from the Indianapolis Motor Speedway, Monday, April 8, 2024, in Indianapolis, Indiana. A total solar eclipse swept across a narrow portion of the North American continent from Mexico’s Pacific coast to the Atlantic coast of Newfoundland, Canada. A partial solar eclipse was visible across the entire North American continent along with parts of Central America and Europe.

Red and Green Aurora Move Through Earth’s Atmosphere
iss072e031823 (Oct. 7, 2024) -- Peering through the window of the SpaceX Dragon Endeavour spacecraft, NASA astronaut Matthew Dominick captured this image of the SpaceX Dragon Freedom spacecraft as vivid green and pink aurora swirled through Earth's atmosphere while the International Space Station soared 273 miles above the Indian Ocean.

RIP Jimmy Carter
Carter wrote the following on June 16, 1977 and placed it in Voyager 1, which is the most distant human-made object from Earth:
This Voyager spacecraft was constructed by the United States of America. We are a community of 240 million human being among the more than 4 billion who inhabit the planet Earth. We human beings are still divided into nation states, but these states are rapidly becoming a single global civilization.
We cast this message into the cosmos. It is likely to survive a billion years into our future, when our civilization is profoundly altered and the surface of the Earth may be vastly changed. Of the 200 billion stars in the Milky Way galaxy, some – perhaps many – may have inhabited planet and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message:
“This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problem we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe.”
--- Jimmy Carter, President of the United States of America, the White House, June 16, 1977

Hubble Spies a Cosmic Eye
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disk takes on an almond shape, giving the galaxy the appearance of a cosmic eye.

NASA Runs X-59 Engine in Maximum Afterburner
NASA’s X-59 quiet supersonic research aircraft completed its first maximum afterburner test at Lockheed Martin’s Skunk Works facility in Palmdale, California. This full-power test, during which the engine generates additional thrust, validates the additional power needed for meeting the testing conditions of the aircraft. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to overcome a major barrier to supersonic flight over land by reducing the noise of sonic booms.

Hang a Shining Star Upon the Highest Bough
Here is a new version of the “Christmas tree cluster.” NGC 2264 is a cluster of young stars between one and five million years old. (For comparison, the Sun is a middle-aged star about 5 billion years old – about 1,000 times older.)

Commercial Moon Rovers Under Test
Through NASA’s Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the Moon’s South Pole region, exploring more of the lunar surface than ever before. Recently, the agency completed the first round of testing on three commercially owned and developed LTVs (Lunar Terrain Vehicle) from Intuitive Machines, Lunar Outpost, and Venturi Astrolab at NASA’s Johnson Space Center in Houston.

NASA’s Terra Satellite Captures 2015 Eclipse Shadow
During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA's Terra satellite passed over the Arctic Ocean on March 20 at 10:45 UTC (6:45 a.m. EDT) and captured the eclipse's shadow over the clouds in the Arctic Ocean.

Gateway: Wired for Deep Space
A maze of cables and sensors snakes through a major piece of Gateway, humanity’s first space station around the Moon, during a key testing phase earlier this year to ensure the lunar-orbiting science lab can withstand the harsh conditions of deep space.

Chandra and Webb Spy a Cosmic Wreath
NGC 602 is a star cluster that lies on the outskirts of the Small Magellanic Cloud, one of the closest galaxies to the Milky Way. This image combines X-rays from NASA's Chandra X-ray Observatory and infrared data from NASA's James Webb Space Telescope (JWST).

Artemis II Core Stage Moves to High Bay 2
Teams with NASA’s Exploration Ground Systems transport lower the agency’s 212-foot-tall SLS (Space Launch System) core stage into High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Dec. 11, 2024. The one-of-a kind lifting beam is designed to lift the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters on top of mobile launcher 1 for the SLS core stage.

Atmospheric Probe Takes Flight
An atmospheric probe model attached upside down to a quad rotor remotely piloted aircraft ascends with the Moon visible on Oct. 22, 2024. The quad rotor aircraft released the probe above Rogers Dry Lake, a flight area adjacent NASA’s Armstrong Flight Research Center in Edwards, California. The probe was designed and built at the center.

Hubble Captures an Edge-On Spiral with Curve Appeal
This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies that we see edge-on.

Orange Lava, Blue Lagoon
Landsat 9 captured this image of lava coming from an eruptive fissure near Stóra Skógfell peak on Iceland's Reykjanes peninsula. Lava from the eruption flowed across major roads and closed in on the Blue Lagoon, a popular tourist destination. This natural color scene is overlaid with an infrared signal to help distinguish the lava’s heat signature.

Astronaut Suni Williams and Astrobee
NASA astronaut and Expedition 72 Commander Suni Williams checks out the Astrobee robotic free-flyer in the Kibo laboratory module outfitted with tentacle-like arms containing gecko-like adhesive pads to demonstrate satellite capture techniques. Development of this robotic technology may increase the life span of satellites and enable the removal of space debris.
