This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope. The colors in Hubble’s visible light image, which marks the 36th anniversary of the mission’s launch on April 24, are reminiscent of an underwater scene filled with fine-grained sediments fluttering through the ocean’s depths.

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way. Astronomers used NASA’s James Webb Space Telescope to examine 29 Cygni b, an object

New nighttime maps based on NASA satellite imagery are upending assumptions, revealing a world where artificial brightening and dimming have intensified over the past decade. The findings show intense flaring over major oil and gas fields in the United States, while factors such as rural electrification and energy conservation are changing how billions around the

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy,

NASA’s first Artemis II science officers—Kelsey Young, Trevor Graff, and Angela Garcia—are pioneering a new era of mission operations by integrating advanced lunar science directly into Mission Control. Their work will shape how future Artemis crews observe, analyze, and deepen our understanding of the Moon.

Patches of open water in the region contributed to low sea ice extent across the Arctic in March 2026, which tied with the lowest maximum observed in the satellite record.

Listen to this audio excerpt from Erik Richards, Near Space Network Mission Manager: For Erik Richards, supporting NASA’s first crewed Artemis mission to the Moon and back is the culmination of a career spent helping spacecraft communicate with Earth. Like many kids who grew up at the height of the Space Shuttle Program, Richards dreamed of spaceflight — a dream that eventually took him from the remote McMurdo Station in Antarctica to

Media are invited Tuesday, April 21, to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for a look at the agency’s Nancy Grace Roman Space Telescope, which recently completed construction and is wrapping up prelaunch testing. This will be one of the last opportunities to view the fully integrated flagship telescope before it ships to

For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence

NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere. Both sense sunlight reflected from Saturn’s banded

For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82.

The highly competitive NASA Hubble Fellowship Program (NHFP) recently named 24 new fellows to its 2026 class. The NHFP enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observations, simulations, experimentation, or instrument development. Over 650 applicants vied for the 2026 fellowships, representing an oversubscription rate of 27

As NASA seeks to understand the mysteries of the universe, the agency is advancing technologies to locate and explore Earth-like planets far beyond our solar system. A key element of this research involves observing reflected light from exoplanets, which can reveal indicators of Earth-like features such as water and oxygen. However, detecting this faint reflected
