A little-studied star, TYC 3203-450-1, upstages a galaxy in this Hubble Telescope image from December 2017. Both the star and the galaxy are within the Lizard constellation, Lacerta. However, the star is much closer than the much more distant galaxy. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy ab...
Auroras and hazes glow in this composite image of Jupiter taken by the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). NIRCam has three specialized infrared filters that showcase details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum: the auroras are mapped to redder co...
This view of the crescent Earth over the Moon’s horizon was taken during the Apollo 15 lunar landing mission. Apollo 15 launched from the Kennedy Space Center on July 26, 1971 via a Saturn V launch vehicle. Aboard was a crew of three astronauts: David R. Scott, mission commander; James B. Irwin, lunar module pilot; and Alfred M. Worden, command module ...
T-38 planes are a fixture of astronaut training, assisting pilots and mission specialists to think quickly in changing situations. Here, our T-38s fly in formation above the Space Launch System (SLS) rocket on Launch Pad 39B. The SLS and Orion spacecraft for the Artemis I mission will launch no earlier than Aug. 29, 2022. Astronaut Andrew Morgan posted this ...
This time lapse of the Milky Way Galaxy taken from the International Space Station (ISS) also captured a lightning strike on Earth so bright that it lit up the space station’s solar panels. Astronaut Kjell Lindgren posted this on Twitter and Instagram on Sept. 2, 2015, saying, “Large lightning strike on Earth lights up or solar panels.” See more ...
The supersonic X-1E research aircraft was the last of NASA’s experimental X-1 series of aircraft. From 1955-1958, it made 26 flights and one captive flight (attached to a carrier aircraft). Research flights took place over what is now NASA’s Armstrong Flight Research Center in Edwards, California. In this photo from November 2021, the X-1E looks toward...
The core of NASA’s Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft’s main body will for the next two years be the focus of attention in the facility’s ultra-hygienic High Bay 1 as engi...
A paddlewheeler makes its way up the Mississippi River as the Moon rises over New Orleans on Sunday evening, Aug. 22, 2021. The August Sturgeon Moon, which was also a rare Blue Moon, was full at 7:02 a.m. local time Sunday but the nearly full Moon still put on a show when it rose over New Orleans later that evening. New Orleans is home to the NASA Michoud As...
Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter ...
NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen atop the mobile launcher as it is rolled up the ramp at Launch Pad 39B, Wednesday, Aug. 17, 2022, at NASA’s Kennedy Space Center in Florida. NASA’s Artemis I mission is the first integrated test of the agency’s deep space exploration systems: the Orion spacecraft, SLS rocket, an...
