SKA Word of the Week

Welcome to the SKA Word of the Week page, our education and outreach initiative designed especially for the web and social media!

Every week, on our social media channels and on this page, our team of leading experts brings you a word, acronym or phrase associated with the SKA to help you better understand our universe. Here you will find everything from AGN, exascale and HPC to Zeeman Splitting. With time, these words will grow into an SKA glossary available right here for you to become more familiar with the SKA.

The SKA Word of the Week exists in ultra-short version on Twitter, in a more developed version on Facebook, and in its complete version on this webpage with more background information and links.

We hope you enjoy this fun, learning tool and share the words of the week with your friends on your social media!


Big Data
SKA Organisation chief Architect Tim Cornwell tells about the IT end of the SKA telescope and its challenges by explaining what we mean when we talk about "Big Data"


Cosmic Magnetism
One of the key science goals of the SKA will be to study cosmic magnetism. Everybody knows about magnetism, but what about cosmic magnetism?


We asked our Director General Phil Diamond to think of one word closely tied to the SKA, and here's what he answered. See what Global means for him in the context of the SKA.
Gravitational wave
In early 2014, the team behind the BICEP2 experiment announced they had discovered evidence of gravitational waves in the Cosmic Microwave Background, which supports the theory of the Big Bang and the inflation of the Universe. So what are gravitational waves?


The SKA is often mentioned with excitement among the HPC (High-Performance Computing) community. Chief Architect Tim Cornwell explains what HPC means.


We often use the word "precursor" when talking about SKA-related telescopes, so what do we mean by this?


Transformational science
The SKA will undertake transformational science that will revolutionise our understanding of physics. But what does this mean? SKAO Director of Science Robert Braun explains.
