Q1208+1011
Q1208+1011 is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Q1208+1011 rather than just read about it. In short: Q1208+1011 is a gravitationally-lensed quasar discovered in April 1986 by Hazard, McMahon and Sargent. It has a redshift of 3.80, and was the most distant astronomical object ever observed at the time of its discovery.
Key takeaways
- Q1208+1011 belongs to astronomy; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Q1208+1011 to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Q1208+1011 from memory before moving on to harder problems.

Worked examples
Example 1 — a first encounter with Q1208+1011
Start with the simplest possible case. Write down what Q1208+1011 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.
Example 2 — changing one variable
Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Q1208+1011 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.
Example 3 — an exam-style question
Typical questions about Q1208+1011 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
Applications of Q1208+1011
- In research
- Q1208+1011 appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
- In technology and industry
- Engineering practice reuses Q1208+1011 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
- In the classroom
- Q1208+1011 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1986, Quasars, Virgo (constellation), so understanding it makes those chapters shorter.
- In everyday life
- Look for Q1208+1011 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
