One of the most interesting characteristics of light is that the path that it travels can bend.

Chandra X-ray Observatory has collected data for over sixteen years on thousands of different objects throughout the Universe.

This galaxy cluster, which was found about 5.7 billion light years from Earth, shattered several important astronomical records.

At the heart of the Milky Way galaxy, there is a supermassive black hole that has the mass equivalent of some four million Suns.

Light comes in different forms. The light that we see with our eyes is just a fraction of all light.

We rely on light - both natural and artificial - to brighten and power our world, but also for so much more.

Understanding how clusters grow is critical to tracking how the Universe itself evolves over time.

Oxymorons are often thought of as gaffes in language, but a new black hole discovery shows they can also represent important scientific advances.

Last time, we looked at the electromagnetic spectrum. This time we'll look at how astronomical images are made.

An astronomer's toolkit consists of many kinds of light, across the electromagnetic spectrum.
