When Daniela, a science teacher from Montevideo, heard that NASA had launched a new space telescope, she stopped her lesson mid-sentence. She had been explaining the solar system to her students when a notification appeared on her phone. "This changes everything we can look for," she told them, setting the phone down on her desk.

Daniela spent the rest of that evening reading everything she could find about the mission. The telescope, which is roughly the size of a tour bus, had been designed to search for planets beyond our solar system. She found that detail particularly striking. Something so large had been built to detect objects unimaginably far away — planets that no human eye had ever seen directly.

The mission's scale impressed her most. According to what she had read, the telescope aims to identify more than 100,000 planets outside our solar system. Daniela told her partner that she could hardly believe that number. She said that scientists had apparently spent years designing instruments sensitive enough to carry out a search of that size. The telescope, whose capabilities had been described as extraordinary by several researchers, was also built to help unravel deeper mysteries about how the universe works.

By the following morning, Daniela had already prepared a new lesson around the launch. She wished she had known about the mission earlier, so she could have planned something more detailed. Still, she felt that the timing might have been perfect. Her students, who had seemed distracted all week, were suddenly asking questions she had never heard from them before. One student asked whether any of those 100,000 planets might support life. Daniela said she did not know — but that was exactly the kind of question the telescope had been launched to help answer.

Grammar Spotlight

Non-defining Relative Clauses

noun + , who / which / whose / where , + extra information

When do we use it?

  • Use a non-defining relative clause to add extra, non-essential information about a noun that is already clearly identified — the sentence still makes sense without it.
  • Choose 'who' for people, 'which' for things or ideas, 'whose' to show possession, and 'where' for places — never use 'that' in non-defining clauses.
  • Use them to make writing richer and more sophisticated by weaving in background details without starting a new sentence.

How is it formed?

noun (already identified)+, who / which / whose / where + extra information ,+main clause continues

Commas are essential — they signal the clause is extra, not defining

★Commas = bonus info you could remove!

See it in action

  1. Daniela, who is a science teacher from Montevideo, stopped her lesson the moment she saw the notification.

  2. NASA's new telescope, which was launched earlier this year, has already changed how scientists search for distant planets.

  3. Daniela's students, whose curiosity about space had been growing all term, were thrilled by the news.

  4. The classroom, where Daniela had been explaining the solar system just minutes before, suddenly felt connected to the universe.

Remember this

Defining (no commas — essential)

  • •The teacher who stopped her lesson was Daniela. (tells us WHICH teacher)
  • •The telescope that NASA launched is revolutionary. (identifies WHICH telescope)

Non-defining (commas — extra info)

  • •Daniela, who stopped her lesson, is a science teacher. (we already know who Daniela is)
  • •The telescope, which NASA launched this year, is revolutionary. (already identified)

If removing the clause makes the noun unclear, it is defining (no commas); if the noun is already identified and the clause is just bonus detail, it is non-defining (use commas).

Discussion Questions

View answers for the comprehension questions
  1. 1.She stopped because the news about NASA's new space telescope felt immediately significant to her science lesson — she recognized that it had direct relevance to what she was teaching her students about the solar system.
  2. 2.She found it striking that something as large as a tour bus had been built to detect planets unimaginably far away — objects that no human eye had ever seen directly. The contrast between the telescope's physical size and the extraordinary distance of its targets made the detail stand out.
  3. 3.The article implies that the launch gave her students a new sense of curiosity and engagement. Students who had seemed distracted all week suddenly began asking questions Daniela had never heard from them before, suggesting the real-world event sparked genuine intellectual interest.
  4. 4.She herself reflects on this, saying she wished she had known earlier so she could have planned something more detailed. It is likely she would have prepared a more thorough lesson in advance rather than putting one together overnight.
  5. 5.The article strongly implies that a timely, real-world scientific event can transform student engagement. Daniela's students shifted from being distracted to asking deep, original questions — suggesting that connecting lessons to live discoveries can have a significant motivational effect.
