What looks like a neon pink treble clef floating out in space is actually a bizarre source of radio waves spotted deep in the cosmos.

Faint in X-rays but bright in ultraviolet light, new objects found by NASA's Chandra space telescope could help solve two great astrophysical mysteries.

A trio of NASA space telescopes teamed up to capture a gorgeous new look at the glowing spiral galaxy NGC 4258 and its two anomalous extra arms.

Using the Chandra X-ray spacecraft, astronomers have seen a jet from a feeding supermassive black hole churning gas surrounding a galaxy nicknamed the "red potato."

NASA's Chandra X-ray Observatory has released four stunning images of cosmic wonders, depicted in red, white and blue for the America 250 anniversary on July 4.

"We could already see changes in the jet, but never with this level of detail in X-rays."

NASA's Chandra X-ray spacecraft has detected the supernova wreckage of a dead star that erupted 1,700 years ago and ejected debris at 2 million miles per hour.

What's the truth behind this unusually tranquil city of galaxies?

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

NASA is canceling the AXIS X-ray space telescope mission concept, saying it failed to meet key requirements. But the project leader thinks there's another reason.
