An experimental, uncrewed and reusable spacecraft being developed by China completed its second mission on Monday after remaining in orbit for 276 days, according to Chinese state media.
Why it matters: Very little is publicly known about the spacecraft, though experts have speculated that it could one day be used to interfere with satellites in orbit.
Climate change made a heat wave that struck Western Europe and Northwest Africa in April at least 100 times more likely to occur, a new study finds.
Why it matters: The study, from the World Weather Attribution initiative, concludes that without human-caused warming, this heat wave would have been "almost impossible." Its findings are based on peer reviewed, published methods, but the new research has not itself been peer reviewed yet.
This is one in a string of studies to come to similar conclusions on extreme heat events.
