Most of us are familiar with Jane Taylor’s nursery rhyme, ‘Twinkle, Twinkle, Little Star,’ which compares the dense balls of burning hydrogen that litter the universe to ‘diamonds in the sky.’ According to new research, Taylor’s charming metaphor can be taken quite literally.

As detailed in a paper published on Wednesday in Nature, astronomers at the University of Warwick in the UK obtained the first direct evidence of a star’s core turning into a crystal of solid oxygen and carbon. What’s more, the research suggests that the sky is full of stars that are undergoing or have completed crystallization and that our own Sun will one day transform into a crystal as well.

The 25 Best Oculus Rift Games Day #5

It was over six years ago now that a small group of people gathered together to run a Kickstarter campaign for a first-of-its-kind VR headset. They raised nearly $2.5 million and the Oculus Rift was born. Fast forward to 2018 and the Rift has been on the market for two and a half years and amassed an impressive ecosystem of games in that time. We’re here to pick the 25 best.

Throughout the week we’re going to be updating this list with five games a day in ranked order, leading up to the game we’ve crowned as, yes, the very best game on the platform. Once we’re done, this will be our new and definitive list, replacing our previous, smaller version. Updates will appear on this very page so make sure to check back through the week.
