The universe is so big that it troubles one's mind to even think about it, but the objects within the universe are equally as astonishing. The Earth seems like a pretty big place however it is merely a spec of dust compared to the largest objects and structures in the universe, the closest object to us that even makes it onto the truly massive scale is our own yellow dwarf star; The Sun. The Sun makes 99.86% of the mass of our solar system and you would be able to fit 1.3 million Earth’s inside of it. On the scale of the cosmos, the Sun is actually pretty tiny compared to VY Canis Majoris which is located around 5000 light years from Earth and is the largest star ever discovered. This red supergiant star has a radius of 950-1200 times the size of the Sun which is simply unassailably big.
In this documentary, we take a look through the largest known objects in the universe. Starting from objects such a the largest volcano in the solar system, Olympus Mons located on Mars. The biggest known stars as aforementioned, the largest galaxy spanning hundreds of thousands of lightyears and then on to galaxy superstructures. The scale of the universe is genuinely incomprehensible from the very small as investigated in the BBC Horizon documentary “How small is the Universe” to the very big. Our imaginations are now having to catch up with the facts.
