An orphaned giraffe nuzzling a wildlife keeper at Sarara camp in Kenya, one of 70 pictures being sold by Prints for Nature (printsfornature.com) to raise money for work by the Conservation International charity.

The International Space Station (ISS) moving in front of the sun in November 2020 by astrophotographer Andrew McCarthy. These incredible photos capture the clearest images ever taken of the International Space Station (ISS) moving in front of both the moon and the sun. The photos, taken within days of one another, were captured in the space of less than a second, as the space station could be clearly seen zooming across against the bright backdrops of both moon and sun. Photographer Andrew McCarthy, from California, USA, said the photo of the ISS in front of the sun, in broad daylight, was “one of my trickiest shots ever”.
