NASA Tech to Use Moonlight to Enhance Measurements from Space

NASA will soon launch a one-of-a-kind instrument, called Arcstone, to improve the quality of data from Earth-viewing sensors in orbit. In this technology demonstration, the mission will measure sunlight reflected from the Moon— a technique called lunar calibration. Such measurements of lunar spectral reflectance can ultimately be used to set a high-accuracy, universal standard for […]

Hubble Studies Small but Mighty Galaxy

This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (the Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of galaxies that the Milky Way […]

NASA Employees Named 2025 Service to America Medals Honorees

Two NASA employees are being  honored as part of the Samuel J. Heyman Service to America Medals, also known as the Sammies, recognizing outstanding federal employees who are addressing many of our country’s greatest challenges. Rich Burns of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and John Blevins of Marshall Space Flight Center in […]

Hubble Studies a Spiral’s Supernova Scene

This serene spiral galaxy hides a cataclysmic past. The galaxy IC 758, shown in this NASA/ESA Hubble Space Telescope image, is situated 60 million light-years away in the constellation Ursa Major. Hubble captured this image in 2023. IC 758 appears peaceful, with its soft blue spiral arms curving gently around its hazy barred center. However, […]

NASA Launching Rockets Into Radio-Disrupting Clouds

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13. The atmospheric features SEED is studying are known as Sporadic-E layers, […]

NASA+ Documentary “Cosmic Dawn” Reveals Untold Story of James Webb Space Telescope 

What does it take to gaze through time to our universe’s very first stars and galaxies?   NASA answers this question in its new documentary, “Cosmic Dawn: The Untold Story of the James Webb Space Telescope.” The agency’s original documentary, which chronicles the story of the most powerful telescope ever deployed in space, was released […]

NASA’s Webb ‘UNCOVERs’ Galaxy Population Driving Cosmic Renovation

Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today. “When it comes to producing ultraviolet light, these small galaxies punch well above their weight,” said Isak Wold, an assistant […]

NASA’s CODEX Captures Unique Views of Sun’s Outer Atmosphere

Key Points: Scientists analyzing data from NASA’s CODEX (Coronal Diagnostic Experiment) investigation have successfully evaluated the instrument’s first images, revealing the speed and temperature of material flowing out from the Sun. These images, shared at a press event Tuesday at the American Astronomical Society meeting in Anchorage, Alaska, illustrate the Sun’s outer atmosphere, or corona, […]

Frigid Exoplanet in Strange Orbit Imaged by NASA’s Webb

A planetary system described as abnormal, chaotic, and strange by researchers has come into clearer view with NASA’s James Webb Space Telescope. Using Webb’s NIRCam (Near-Infrared Camera), researchers have successfully imaged one of two known planets surrounding the star 14 Herculis, located 60 light-years away from Earth in our own Milky Way galaxy. The exoplanet, […]

Hubble Captures Starry Spectacle

A galaxy ablaze with young stars is the subject of this NASA/ESA Hubble Space Telescope image. Named NGC 685, this galaxy is situated about 64 million light-years away in the constellation Eridanus (the River). NGC 685 is a barred spiral because its feathery spiral arms sprout from the ends of a bar of stars at […]
