# NASA paints the cosmos red, white and blue for America's 250th

To mark the United States' 250th anniversary, NASA's Chandra X-ray Observatory has released a set of cosmic images rendered in red, white and blue — a patriotic flourish wrapped around some genuinely striking science about the universe's most violent places.

It is part celebration, part demonstration of how modern astronomy actually works.

## The images

NASA's Chandra X-ray Observatory team has [released a set of composite images](https://science.nasa.gov/missions/chandra/nasas-chandra-reveals-red-white-blue-universe-for-us-250th/) of cosmic objects, processed in red, white and blue, to mark the United States' 250th anniversary in 2026. The collection features Cassiopeia A, the glowing debris of an exploded star; NGC 3603, a nebula cradling a cluster of young stars; the spiral galaxy Messier 94; and ZwCl 0024+1652, a distant cluster of galaxies.

The colors are not what your eye would see. They are a code: each hue marks data from a different telescope, layered into a single picture. The blues and purples generally show the X-rays that Chandra itself detects — high-energy radiation that pours out of the universe's hottest, most extreme environments — while reds, whites and other tones carry infrared, visible-light and other data from observatories such as the James Webb and Hubble space telescopes and ground-based instruments.

## What Chandra sees

Launched in 1999, [Chandra is one of NASA's "Great Observatories,"](https://science.nasa.gov/missions/chandra/) a fleet that includes Hubble. Where visible-light telescopes show starlight, Chandra reveals the X-ray universe: the searing neighborhoods around black holes, the shock waves of exploded stars, and the billion-degree gas that fills the space between galaxies in giant clusters — gas so hot it shines only in X-rays and would be invisible to any ordinary camera.

That is why the featured objects were chosen. Cassiopeia A is a supernova remnant whose blast wave is still expanding centuries after the star tore itself apart. NGC 3603 is a stellar nursery lit up by the X-rays of massive young stars. And the glow of a galaxy cluster like ZwCl 0024+1652 traces vast reservoirs of superheated gas binding hundreds of galaxies together.

## Pride and wonder

Space agencies often produce themed imagery to mark anniversaries and draw the public's eye, and this release is squarely in that tradition. But the patriotic palette also illustrates a serious point about how astronomers work: no single wavelength of light tells the whole story. By combining X-ray, infrared and visible data, researchers build a fuller portrait of objects that shaped the cosmos. Nearly 27 years after it launched, Chandra is still helping to paint that picture — this time, for a birthday.
