Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Sum up what this says about mustard donuts. 

Just when you thought you would be hoarding mustard, thanks to a potential upcoming shortage, along comes another option for enjoying this condiment — and it’s not what you think. 

French’s Mustard is celebrating National Mustard Day (August 6) with a surprising tangy treat: the French’s Mustard Donut. Consumers nationwide can get their hands on this limited-edition snack for free this Saturday — both in-store at Brooklyn-based artisanal bakery Dough Doughnuts and nationwide online.


Created in partnership with the iconic donut shop, this mustard-flavored hole is a far cry from the condiment’s original intro in 1904 on a hot dog at St. Louis’s famous World’s Fair. But we’re not mad. The bold flavor of French’s Classic Yellow Mustard and Dough’s signature brioche recipe allows donut-devourers and mustard-lovers to come together for a reimagined classic glazed option topped with a vibrant sweet and savory mustard coating and cake crumble.
Response: The French’s Mustard company is celebrating National Mustard Day (August 6) by releasing a mustard-flavored donut, which they plan to give out limited editions of for free in some places. This is very different from its original release, but mustard lovers should enjoy it.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Explain the purpose of the Hubble Space Telescope mentioned in the following paragraph:

The Hubble Space Telescope, launched into low Earth orbit in 1990, has provided some of the most detailed images of celestial objects ever seen. Its mission is to gather data on the universe's structure and the life cycles of stars and galaxies. By observing in various wavelengths, it has expanded our knowledge about dark matter, black holes, and the evolution of the cosmos.
