This week, the UK endured a record-breaking
heatwave which has also been affecting vast swathes of Europe, with numerous damaging wildfires affecting many countries, including France, Spain, Portugal, Greece and Italy. Temperatures in the UK hit 40°C in a number of locations, while in Portugal, a temperature of 47°C was recorded.
In happier news, three critically endangered Sumatran tiger cubs made their first public appearance this week at London Zoo. The tigers, who are on the IUCN red list of threatened animals, are so far developing well.
If you are a fan of stargazing, or even just looking to make a wish or two, the
Perseid meteor shower started this week, and should be visible for a number of weeks.

These jellyfish are small, yet covered in many stinging cells that can cause pain long after contact. They can also be damaging to tourism, emptying beaches if they appear in large numbers.

The sophisticated robot, known as the Sample Transfer Arm, as seen in this image released on 19 July 2022, will play a crucial role in the success of the Mars Sample Return campaign. The joint endeavour between NASA and ESA aims to bring martian samples to Earth by 2033.

The cubs remained inside the Zoo’s behind-the-scenes cubbing den for the first few weeks of their lives, before recent warm weather prompted Gaysha to bring them outside.
