Discover how dying stars transform into black holes, areas of mass so great that even light can't escape. Physics - Universe - Learning Points. When a star dies, it collapses and condenses into a single point, known as a singularity. The...

What are stars made of? How are they born, how do they live, and how do they die? Physics - Our Solar System - Learning Points. Our nearest star is the Sun. A star is formed from a cloud of dust and gas, which shrinks under gravity and...

The Sun is dying, and getting hotter as it does. As life on Earth becomes unsustainable, could we move to Mars? Physics - Universe - Learning Points. The Sun will die in approximately 5 billion years. As the Sun ages, it will get hotter,...
