India’s space agency ISRO plans to launch Aditya-L1, a satellite designed to observe the Sun, on 2 September. The spacecraft will travel to the Sun–Earth Lagrange Point 1, about 1.5 million kilometres from Earth, where it can keep the Sun continuously in view. The mission follows India’s successful Chandrayaan-3 Moon landing and represents a major step in the country’s expanding space programme, aimed at improving understanding of solar activity.

Britain and Spain were narrowly divided on the question.

Apple has filed a patent application that describes using motion sensing to detect lip and head movements so Siri could recognize commands without relying only on a microphone.

Spain's annual Tomatina festival draws thousands each year to the town of Buñol, where participants playfully pelt one another with overripe tomatoes.

The event lasts about an hour, and people commonly wear goggles and old clothes; there is a small participation fee of about €12 to help manage the crowd.
