ON 23 September 1938, engineers from the Westinghouse Electric & Manufacturing Company sank a time capsule deep into the ground at Flushing Meadows Park in New York City, venue of the 1939 World’s Fair. Among other artefacts, the contained a printed “key to English” that described the words, sounds and grammar of 20th-century American English to help its discoverers, 5000 years in the future, understand a language that presumably would be as foreign to them as Hittite is to us.
The author of the document, John Harrington of the Smithsonian Institution in Washington DC, presumed that modern English would be radically changed by the year 6939. But how? Is it possible to say what English will be like 5000 years from now, or even 500?
Will it be like this: “I punya manglish iz wely chekai wan lah, singlish lagi terok, i tok chinglish beter”?*
Or this: “Our Father, who comes to us from above, your name is holy”?**
Or this: “It musve ben some girt jynt thing hy hy up and with a shyning and a flashing to it time back way back when they had boats in the air and all the res of it”?***
It’s a safe bet that the discoverers of the Westinghouse time capsule will need to use Harrington’s key, because 5000 years is a long time in the life of any language. Only 1600 years ago, the people who spoke the languages that would form the core of English had not yet migrated to England. A thousand years ago, English was a language so different from our own you’d have to learn it as a foreign language; very few people…
![Astronomers have long known that understanding how star clusters come to be is key to unlocking other secrets of galactic evolution. Stars form in clusters, created when clouds of gas collapse under gravity. As more and more stars are born in a collapsing cloud, strong stellar winds, harsh ultraviolet radiation and the supernova explosions of massive stars eventually disperse the cloud, and their light can bear down on other star-forming regions in the galaxy. This process is called stellar feedback, and it means that most of the gas in a galaxy never gets used for star formation. Researching how star clusters develop can answer questions about star formation at a galactic scale. Now, the state of the art has been further developed with both Hubble and Webb working together to provide a broad-spectrum view of thousands of young star clusters. An international team of astronomers has pored over images of four nearby galaxies from the FEAST observing programme (#1783), trying to solve this mystery. Their results show that it is the most massive star clusters that clear away their gaseous shroud the fastest, and begin lighting their galaxy the earliest. The team identified nearly 9000 star clusters in the four galaxies in different evolutionary stages: young clusters just starting to emerge from their natal clouds of gas, clusters that had partially dispersed the gas (both from Webb images), and fully unobstructed clusters visible in optical light (found in Hubble images). With Webb???s ability to peer inside the gas clouds, they were able to then estimate the mass and age of each cluster from its light spectrum. This image shows a section of one of the spiral arms of Messier 51 (M51), one of the four galaxies studied in this work, as seen by Webb???s Near-Infrared Camera (NIRCam). The thick clumps of star-forming gas are shown here in red and orange, representing infrared light emitted by ionised gas, dust grains, and complex molecules such as polycyclic aromatic hydrocarbons (PAHs). Within these gas complexes, each tens or hundreds of light years across, Webb reveals the dense, extremely bright clusters of massive stars that have just recently formed. The countless stars strewn across the arm of the galaxy, many of which would be invisible to our eyes behind layers of dust, are also laid bare in infrared light. [Image description: A large, long portion of one of the spiral arms in galaxy M51. Red-orange, clumpy filaments of gas and dust that stretch in a chain from left to right comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small stars. A faint blue glow around the arm colours the otherwise dark background.]](https://images.newscientist.com/wp-content/uploads/2026/05/13114322/SEI_296271016.jpg)
