Evening eclipse. Just before the Sun set on 2 July, observers at La Silla Observatory in the Atacama Desert, Chile, were treated to the sight of a total solar eclipse. This composite photo shows the path of the setting Sun and the moment that it was completely obscured by the Moon.
Bird breath. On a cold Virginia morning, amateur photographer Kathrin Swoboda snapped this red-winged blackbird (Agelaius phoeniceus) blowing out what look like smoke rings. The rings are actually formed by the warm, condensed breath of the bird as it sings. The photo won Swoboda the grand prize in the 2019 Audubon Photography Awards.
High-resolution brain. Researchers have imaged an entire human brain in greater detail than ever before. Scientists have developed a specially designed container and custom electronics to conduct magnetic resonance imaging on the organ, donated by a 58-year-old woman. The scan took 100 hours and generated 8 terabytes of data, the researchers report in a paper posted on 31 May on the preprint server bioRxiv1. The resulting image has a resolution of 100 micrometres; previously, only small regions of the brain had been imaged in such detail.
Rover assembly. Engineers at NASA’s Jet Propulsion Lab in Pasadena, California, install legs and wheels on the agency’s Mars 2020 rover. The assembly takes place in a clean room, and the team members wear ‘bunny suits’ to prevent any contamination. The mission will launch in July 2020, and the rover will land on Mars in February the following year.
Bleached anemone. Just like coral, sea anemones can be bleached by excess exposure to heat and light. This anemone in the Red Sea has lost the algae it once hosted — which provided it with oxygen and food — and has become colourless. Bleaching events are becoming more common with the warming climate. This image by Morgan Bennett-Smith won the ‘Human Impact’ category in Ocean Conservancy’s 2019 photo contest.
Moon light. July marked the 50th anniversary of the Apollo 11 Moon landing, with commemorative events taking place around the world. In Washington DC, a celebratory light show at the Washington Monument included this life-size projection of the Saturn V rocket used during the Apollo mi
