Aurora – the dancing glow of ionised particles in Earth’s upper atmosphere – is not unique to our planet.

Long before corporations acknowledged Black Lives Matter, they championed the plights of specific endangered species.

To human eyes, Saturn’s moon Enceladus looks relatively plain. Shift the wavelength away from the optical, however, and Enceladus starts to look a lot more interesting, as new images amply demonstrate. Although its surface is scored with deep chasms and gorges, Enceladus seems fairly uniform otherwise, with a glistening white ice shell, like a giant snowball

As a species, humans have populated almost every corner of the earth. We have developed technologies and cultures which shape the world we live in.
