Free CPD-Accredited Course Opens the Cosmos to Curious Minds Everywhere
Alison has launched a new CPD-accredited course: Decoding the Universe: An Introduction to Astrophysics. This free online course demystifies the science of space — explaining how stars are born and die, how galaxies form, what black holes actually are, and how astronomers piece together the history of the universe from light that has travelled billions of years to reach us. Reviewed by Dr. Nina Stankovic, who holds a PhD in Physics, the course requires no scientific background and is designed for anyone who has ever looked up and wanted to understand what they are looking at.
The course guides learners through the core concepts of astrophysics in plain language: the nature of light and electromagnetic radiation, the life cycles of stars, planetary systems and their formation, the structure and scale of galaxies, cosmic events such as supernovae and neutron stars, and the origins and large-scale structure of the universe itself. Each topic builds genuine understanding rather than surface-level familiarity, giving learners the tools to follow real scientific discussions and discoveries with confidence.
A Golden Age of Space Discovery — and a Widening Knowledge Gap
We are living through one of the most extraordinary periods in the history of space science. The James Webb Space Telescope, fully operational since 2022, has captured images of galaxies more than 13 billion light years away — light that left its source before Earth existed. Its observations have challenged existing models of early galaxy formation and opened new questions about the rate at which the universe is expanding. Meanwhile, missions to Mars, the detection of thousands of exoplanets beyond our solar system, and the first images of a black hole's event horizon have brought astrophysics to the front pages of newspapers worldwide.
Yet for most people, these discoveries arrive as spectacular images with little context for what they mean. The science behind them — how we measure cosmic distances, what the spectrum of a star's light tells us about its temperature and composition, why certain stars collapse into neutron stars while others become black holes — remains inaccessible to anyone without a university background. The observable universe spans an estimated 93 billion light years and contains approximately two trillion galaxies. Most of us have no framework for what any of that means.
Why Astrophysics Education Belongs to Everyone
Mike Feerick, Founder and CEO of Alison, stated: "Curiosity about the universe is one of the most universal things about being human. We think everyone — regardless of their educational background or where they live — deserves access to the knowledge that helps them understand what scientists are discovering about the cosmos. This course was built for the person who has always wanted to understand space, not just look at it."
This launch expands Alison's growing portfolio of science and STEM education courses, reinforcing its commitment to making the knowledge of universities and research institutions freely available to every learner on the planet.
