Within the tempestuous Carina Nebula lies “Mystic Mountain.” This three-light-year-tall cosmic pinnacle, imaged by the Hubble Space Telescope’s Wide Field Camera 3 in 2010, is made up primarily of dust and gas, and exhibits signs of intense star-forming activity. The colors in this composite image correspond to the glow of oxygen (blue), hydrogen and nitroge...
This NASA/ESA Hubble Space Telescope observation has captured the galaxy CGCG 396-2, an unusual multi-armed galaxy merger which lies around 520 million light-years from Earth in the constellation Orion. This observation is a gem from the Galaxy Zoo project, a citizen science project involving hundreds of thousands of volunteers from around the world who clas...
We’re less than one week away from the July 12, 2022, release of the first science-quality images from NASA’s James Webb Space Telescope, but how does the observatory find and lock onto its targets? Webb’s Fine Guidance Sensor (FGS), developed by the Canadian Space Agency, was designed with this particular question in mind. Recently it captured a...
A new NASA citizen science project, Jovian Vortex Hunter, seeks your help spotting vortices – spiral wind patterns – and other phenomena in photos of the planet Jupiter. Another NASA citizen science project, called Junocam, seeks help from members of the public processing images from NASA’s Juno Mission and choosing targets for the spacecraft. However, the n...
The last rays of an orbital sunset burst through Earth’s horizon as the International Space Station flew 258 miles above Brazil in this image from June 2022. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. Want more station facts? Visit International Space Station Facts and Figures. Image Credit: NASA...
In this image from 2014, an adult osprey, carrying a fish in its talons, prepares to land in its nest atop a speaker platform in the press site parking lot at NASA’s Kennedy Space Center in Florida. In the background is the 209-foot-tall U.S. flag painted on the side of the 52-story Vehicle Assembly Building, which serves as the central hub of NASA’s p...
NASA’s Oceans Melting Greenland, or OMG, airborne mission found that most of Greenland’s glaciers that empty into the ocean are at greater risk of rapid ice loss than previously understood. OMG’s six-year field campaign studied the ocean’s role in glacial ice loss by gathering precise measurements of ocean depth, temperature, and sali...
In this image from 2014, brightly glowing plumes of the Large Magellanic Cloud (LMC) appear almost like an ocean current with turquoise-tinted currents and nebulous strands reaching out into the surroundings. This image shows part of the Tarantula Nebula’s outskirts located within the LMC, a small nearby galaxy that orbits the Milky Way and appears as ...
A NASA CubeSat designed to test a unique lunar orbit is safely in space and on the first leg of its journey to the Moon. The spacecraft is heading toward an orbit intended in the future for Gateway, a lunar space station built by the agency and its commercial and international partners that will support NASA’s Artemis program, including astronaut missions. T...
“A piece of my story that I think needs to get told is that broken crayons still color. “So often we hear that there’s this cycle of hurt, and hurt people hurt people, and if you came from something, you have to be a product of your environment. “I do feel like, in a lot of ways, we are, whether you want to be or not. The people that ...
