Present perfect continuous — used to describe ongoing research or actions that started in the past and are still relevant now. "Scientists have been looking at an exoplanet."
Adjective vs. noun use of 'potential' — as a noun it means existing capability ("the data has potential"); as an adjective it refers to future possibility ("potential atmosphere"). "Scientists are looking at the potential atmosphere around TRAPPIST-1e."
Passive voice with 'dominated' — shows that something is controlled by or mostly made up of something else. "The atmosphere of TRAPPIST-1e is dominated by nitrogen."
Indirect speech / reporting verbs — the hosts summarise what Caroline said using verbs like explains, mentions, and goes on to say, a common feature of English news and educational discourse. "Caroline explains that scientists have discovered that the planet exists in the habitable zone."
About this video
This episode of BBC Learning English's 6 Minute English series focuses on the exoplanet TRAPPIST-1e — a rocky, Earth-sized planet 40 light years away that sits in the "habitable zone" around its star. Hosts Neil and Becca chat with science journalist Caroline Steele, who explains how scientists have ruled out a hydrogen- or carbon dioxide-heavy atmosphere and found small clues pointing to nitrogen dominance — a possible sign of life. The episode also includes a fun quiz question: how long would it take to drive a car to the Sun at 100 km/h? (The answer is 170 years, not 1,700!)
For shadowing practice, this video is close to ideal at the A2 level. Neil and Becca speak at a clear, measured pace with standard British accents and very little overlap. The dialogue alternates naturally between two speakers, giving learners short, manageable chunks to repeat. Caroline Steele's expert commentary introduces slightly more complex sentence structures, offering a gentle step-up challenge within the same listen.
This episode suits beginner-to-lower-intermediate learners (A2–B1) who want to build confidence with science and space vocabulary in everyday conversational English. By shadowing it, learners will practise noun phrases like habitable zone and potential atmosphere, get comfortable with the phrasal verb rule out, and pick up the natural rhythm of British small-talk and question-answer dialogue.
Idioms & expressions
rule out — to dismiss or eliminate a possibility entirely. (Scientists have ruled out that the planet is full of hydrogen.)
fingers crossed — an expression (sometimes a physical gesture) used to hope for a good or lucky outcome. (Caroline says "fingers crossed it has enough nitrogen.")
step closer — making incremental progress toward a goal. ("That's one step closer to finding life.")
head over to — to go to a place or website, used informally. ("Head over to our website for a quiz.")
find out — to discover or learn information, especially after waiting. ("We'll find out the answer to the question later.")
go on to — to continue doing something, especially after finishing something else. ("Caroline goes on to explain why they think TRAPPIST-1e may be habitable.")
