The difference between dark matter and dark energy, simply explained.
Dark matter could be made of black holes
Are tiny black holes the gravitational glue holding galaxies together?
If dark matter is everywhere, why do some galaxies seem to contain none at all?
What does it mean to find a galaxy without dark matter, or with very little of it?
7 pioneering dark matter scientists
The term ‘dark matter’ was coined over a century ago. Here are 7 scientists who shed light on astronomy’s biggest mystery.

Cosmologist and author Dr Paul Parsons tackles the subject of dark matter. The extract is taken from his new book, The Beginning and the End of Everything, which explores the story of the cosmos from the Big Bang to the end of the Universe.
Latest hunt for dark matter begins
The Axion Dark Matter Experiment will begin its quest to find axions - a hypothetical particle that could explain dark matter.
Big and Small in Space at Ed Sci Festival
In its first week, the Edinburgh International Science Festival 2018 examined the implications of scale in the cosmos, reports space writer Paul F Cockburn.

Scientists have released the most accurate map to date of the structure of dark matter in the Universe, supporting the theory that dark energy and dark matter make up most of the cosmos.
What is dark matter?
The Universe consists mostly of the unknown substances dark matter and dark energy, but what exactly are they?
Dark matter left early galaxies alone
Early spiral galaxies spun much slower than those in the current Universe, implying that dark matter did not dominate their mass at these times.
Galaxy found that is 99.99% dark matter
The exact nature of the elusive substance known as dark matter remains a mystery, but observations of massive cosmic structures may hold the key. The latest discovery is a galaxy that consists almost entirely of dark matter.
Universe is expanding faster than expected
The Hubble Space Telescope has revealed that the modern Universe is expanding at a faster rate than it did shortly after the Big Bang.

A new survey mapping dark matter is giving astronomers the techniques to understand more about dark energy and its role in the expansion of the Universe.
Black holes could be ideal dark matter labs
The gamma rays produced when dark matter particles collide are rare and difficult to observe. A new NASA simulation shows how the power of black holes could provide conditions for greater detection.
