Explained: Here’s how Earth could meet its end

A team of mostly US-based researchers have identified a planet that is heading toward a collision with its ageing sun. This could potentially offer a glimpse into how Earth could end one day

Astronomers spot ‘invisible’ black hole for the first time using Hubble Space Telescope

While it may seem that black holes are by definition invisible, they can still be detected through the way they interact with other objects owing to their strong gravity

Brightest comet of 2021 to pass by Earth on 12 Dec; here's all you need to know

The comet is travelling at a speed of 158,084 miles per hour (71 kilometres per second), but due to its distance from the Earth, it will appear as a slow-moving object to observers
