The hot temperatures are still causing problems across Europe, with damaging wildfires in Germany, the Czech Republic, Spain and France. Meanwhile, California in the USA has also been hit with its biggest wildfire of the year so far, causing huge amounts of damage to land and wildlife.
Meanwhile, high above the Earth, Samantha Cristoforetti became the first European woman to conduct a spacewalk. Over the course of seven hours spent outside the
International Space Station, Samantha helped to prepare the European Robotic Arm for its first operations.
In sad news, visionary scientist James Lovelock passed away at the age of 103 this week. Lovelock is best known as the creator of the
Gaia hypothesis, which proposes that life on Earth functions as a single self-regulating organism.

Scientists, who participated in an Arctic research mission, have returned to Istanbul after the 22-day expedition. A team of nine scientists, who sailed in the Barents Sea with a research vessel called Polar eXplorer, carried out scientific research for 14 different projects at 24 different locations.

There are tiny ripples on the tops of the dunes, only several metres from crest-to-crest. These merge into larger mega-ripples that radiate outward from the dunes. The larger, brighter formations that are roughly parallel are called 'Transverse Aeolian Ridges' (TAR). These TAR are covered with very coarse sand. The mega-ripples appear blue-green on one side of an enhanced colour cutout while the TAR appear brighter blue on the other. This could be because the TAR are actively moving under the force of the wind, clearing away darker dust and making them brighter. All of these different features can indicate which way the wind was blowing when they formed. Photo by NASA/JPL-Caltech/University of Arizona Cheers drive! Driver?

Not only that, but this spacewalk was also the first conducted by a European woman, and the first conducted by a European in an Orlan spacesuit from the International Space Station.
