One of the most exciting developments in astronomy in the last couple of decades has been the discovery and study of planets around stars other than our Sun.

The AstrOlympics project explores the spectacular range of science that we can find both in the impressive feats of the Olympic Games as well as in cosmic phenomena throughout the Universe.

The new results suggest that at least some of the supermassive black holes in the early Universe formed through this direct collapse method.

In modern times, astronomers have observed the debris field from this explosion - what is now known as Tycho's supernova remnant - with many telescopes including the Chandra X-ray Observatory.

A new study tries to tackle the questions surrounding dark energy by examining properties of X-ray emission from galaxy clusters.

Recently, astronomers have performed such a study using observations with Chandra of two comets, named ISON and PanSTARRS.

A little more than a century ago, as seen from the Earth, a star exploded near the center of the Milky Way galaxy.

A new study using data from Chandra X-ray Observatory has shown that storms from the Sun are triggering auroras in X-ray light.

Two of these Frontier Fields galaxy clusters, going by their abbreviated names, are MACS J0416 and MACS J0717.

Astronomers have used Chandra X-ray Observatory to discover a jet from a very distant supermassive black hole being illuminated by the oldest light in the Universe.
