Tens of thousands of people a year, ranging from 3-year-olds to 93-year-olds. And one of the things everyone finds hard to comprehend is the sheer scale of the universe. We’re used to dealing with a daily existence spanning mere metres. Sometimes we drive hundred of kilometres; […]

Some of those rings – made of house-sized chunks of ice – have recently been snapped by the Cassini space probe alongside the planet’s diminutive moon Epimetheus (just 113 kilometres across). Released today, but taken on December 5, 2014, Cassini was 2 million kilometres […]

For more than 20 years now it has been churning out spectacular views of the cosmos. And this latest image of the galaxy NGC 7714 is no exception.   It beautifully illustrates how, over time, gravity can sculpt wondrous sights out of galaxies. A […]

They were first discovered in 1976 and their exact nature remains elusive. The new image shows […]

Those observations appear to reveal the asteroid has a moon of its own. The main asteroid is 325 metres across and its companion measures 70 metres. Click the image below to see an […]

Now they have released details of its dimensions and possible evidence of alien moons nestled within. The rings encircle the planet J1407b. As the planet orbits its star, its set of more than 30 rings periodically blocks out some of the star’s light. Such […]
