Astronomers have used Chandra X-ray Observatory and other telescopes to show that a very distant galaxy is undergoing an extraordinary boom of stellar construction.

The story of how stars are born and eventually die can be a complicated one.

Astronomers have found a pair of extraordinary objects that dramatically burst in X-rays. This discovery, made using data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton observatory, may represent a new class of explosive events.

Each year, Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data that have been stored in its archive.

The Sun can create powerful storms capable of knocking out communication satellites and damaging electrical power systems on Earth.

First discovered in observations from Chandra and XMM-Newton over a decade ago, this object has some interesting properties.

During the summer of 2015, scientists and the public alike were treated to a flood of images and discoveries about Pluto as the New Horizon spacecraft made an unprecedented flyby of the dwarf planet.

When stars have more than about 8 times as much mass as the Sun, they end their lives in a spectacular explosion called a supernova.

Galaxy clusters are incredibly important objects in the Universe since they are the largest objects in the Universe held together by gravity.

In science, pressure is defined as the amount of force over a given area. This means you can have the same amount of force over two different areas and end up with different results.
