Despite searching with NASA's Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh billions of times the mass of the Sun is anywhere to be found.

A new trio of examples of 'data sonification' from NASA missions provides a new method to enjoy an arrangement of cosmic objects.

Astronomers using Chandra have found a bubble of ultra-hot gas at the center of a planetary nebula in our galaxy called IC 4593.

A new study using data from NASA's Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy?

What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common?

Scientists have studied more than 700 quasars -- rapidly growing supermassive black holes -- to isolate the factors that determine why some of these black holes launch jets and others do not.

By turning Chandra, Hubble, and Spitzer images into sounds, a new project allows users to 'listen' to the center of the Milky Way and other objects.

Humanity has "eyes" that can detect all different types of light through telescopes around the globe and a fleet of observatories in space. From radio waves to gamma rays, this multiwavelength approach to astronomy is crucial to getting a complete understanding of objects in space.

A new sequence of Chandra images, taken over nearly a decade and a half, captures motion in Kepler's supernova remnant.

Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster.
