SpARCS1049+56

SpARCS1049+56 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 SpARCS1049+56 rather than just read about it. In short: SpARCS1049+56 is a galaxy cluster whose heart is bursting with new stars and located at a distance of about 9.8 billion light-years away from Earth. It was discovered by NASA's Hubble and Spitzer space telescopes on 2015.

Key takeaways

SpARCS1049+56 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SpARCS1049+56 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SpARCS1049+56 from memory before moving on to harder problems.

Reference excerpt

SpARCS1049+56 is a galaxy cluster whose heart is bursting with new stars and located at a distance of about 9.8 billion light-years away from Earth. It was discovered by NASA's Hubble and Spitzer space telescopes on 2015. The galaxy cluster has a redshift of 1.7 and a mass of (3.5±1.2)×1014 M☉ estimated from weak gravitational lensing.

Worked examples

Example 1 — a first encounter with SpARCS1049+56

Start with the simplest possible case. Write down what SpARCS1049+56 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 SpARCS1049+56 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 SpARCS1049+56 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 SpARCS1049+56

In research: SpARCS1049+56 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 SpARCS1049+56 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: SpARCS1049+56 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Galaxy cluster stubs, Galaxy clusters, Ursa Major, so understanding it makes those chapters shorter.
In everyday life: Look for SpARCS1049+56 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.
