A short time ago, the VISTA (Visible and Infrared Survey Telescope for Astronomy) was doing a “warm-up” routine. It was pointed to a random spot and took a photo. You know, like you, with a new camera, might take a shot of the street outside your house.

But in this analogy, when you took a shot of that street outside your house, you caught the newest Ferrari driving by, or of that model from the Fiat Abarth commercial, or of . VISTA, in an unintentional moment, captured a stunning image of 47 Tucanae, otherwise known as NGC 104.
