Select three words you have highlighted to recycle into your own sentences. Identify all the words in the article that you think are not common words, and particularly good choices for the writer to have chosen. Some are in the glossary, but there might be extra ones from the article that you think are exceptional as well. There are plenty of wow words (ambitious pieces of vocabulary) being used in the article.

Rewrite the article for someone who is ‘time poor’ so that they could get the gist of the story in under 100 words. This news story is quite long and includes a lot of detail. Though the presence of a black hole was thought to be the only plausible* explanation, the new image provides the first, direct visual proof. In the 1990s, astronomers mapped the orbits of the brightest stars near the centre of the Milky Way, confirming the presence of a supermassive compact object there, work that led to the 2020 Nobel prize in Physics. Located 27,000 light years from Earth, its existence has been assumed since 1974 when an unusual radio source was detected at the centre of the galaxy. The black hole has been given the name Sagittarius A* (pronounced A-star), or Sgr A* for short, because it was detected in the direction of the constellation* Sagittarius. Picture: AFPĮHT project scientist Geoffrey Bower, of Taiwan’s Academia Sinica, said: “These unprecedented* observations have greatly improved our understanding of what happens at the very centre of our galaxy.” Media_camera Center for Astrophysics astrophysicist Michael Johnson speaks during a news conference in Washington DC to announce the first image of Sagittarius A*, a supermassive black hole at the centre of the Milky Way galaxy. This glowing halo* swirls around the black hole’s boundary beyond which nothing, not even light, can escape its gravitational pull*.ĭr Issaoun said that from Earth the black hole would look about the same size as a doughnut on the surface of the Moon. The image does not show the black hole itself – because it is completely dark – but the glowing ultra-hot plasma* and gas that encircles the phenomenon* in a bright ringlike structure. “Today, right this moment, we have direct evidence that this object is a black hole.” “For decades, we have known about a compact object that is at the heart of our galaxy that is four million times more massive than our Sun,” said Harvard University astronomer Dr Sara Issaoun. The image, produced by a global team of scientists known as the Event Horizon Telescope (EHT) Collaboration, is the first, direct visual confirmation of the presence of this invisible object, and comes three years after the very first image of a black hole from a distant galaxy. An international team of astronomers has captured the first image of a supermassive black hole at the centre of our own Milky Way galaxy.
