Sculpted by Luminous Stars

Mon, 04/14/2025 - 2:23pm
This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and the Hubble Space Telescope have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.

Sixty Years in Canberra: NASA’s Deep Space Network

Tue, 04/08/2025 - 3:36pm
This March 4, 2020, image shows Deep Space Station 43, a 70-meter-wide (230-feet-wide) radio antenna at NASA’s Deep Space Network facility in Canberra, Australia. The facility celebrated its 60th anniversary on March 19, 2025, while also breaking ground on a new radio antenna. The pair of achievements are major milestones for the network, which communicates with spacecraft all over the solar system using giant dish antennas located at three complexes around the globe.

X-ray Clues Reveal Destroyed Planet

Wed, 04/02/2025 - 1:10pm
In about 5 billion years, our Sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful – as is the case with this planetary nebula called the Helix Nebula. Astronomers study these objects by looking at all kinds of light. This images show X-rays from NASA's Chandra X-ray Observatory (magenta), optical light data from NASA's Hubble Space Telescope (orange, light blue), infrared data from the European Southern Observatory VISTA telescope (gold, dark blue), and ultraviolet data from GALEX (purple) of the Helix Nebula.

Turning Vanes inside the Altitude Wind Tunnel

Fri, 03/28/2025 - 12:55pm
In this February 1944 publicity photo, men stand in front of turning vanes inside the Altitude Wind Tunnel (AWT) at the National Advisory Committee for Aeronautics Aircraft Engine Research Laboratory. The AWT was the only wind tunnel capable of testing full-size aircraft engines in simulated altitude conditions. A large wooden drive fan, located on the other side of these vanes, created wind speeds up to 500 miles per hour.

Like Sands Through the Hourglass…

Mon, 03/24/2025 - 2:25pm
Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows incredible new detail and structure within these lobes, including asymmetrical lines that appear to run into one another. L483 is 650 light-years away in the constellation Serpens.
