IC 1296

IC 1296 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 IC 1296 rather than just read about it. In short: IC 1296 is an extremely faint barred spiral galaxy of Hubble-type SBbc in the constellation Lyra in the northern sky. It is estimated to be 238 million light-years from the Milky Way and about 97,000 light-years in diameter.

Key takeaways

IC 1296 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IC 1296 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IC 1296 from memory before moving on to harder problems.

Reference excerpt

IC 1296 is an extremely faint barred spiral galaxy of Hubble-type SBbc in the constellation Lyra in the northern sky. It is estimated to be 238 million light-years from the Milky Way and about 97,000 light-years in diameter. It was discovered by Edward Emerson Barnard on October 2, 1893. IC 1296 is only 4 arc minutes away from the well-known Ring Nebula in the night sky. Planetary nebulae and galaxies are rarely observed together because planetary nebulae are galactic objects and are concentrated toward our galactic center, where extragalactic objects – such as distant galaxies – are rarely observed there due to absorption by gas and dust.

Supernova One supernova has been observed in IC 1296: SN 2013ev (Type II, mag. 17.2) was discovered by the Italian Supernovae Search Project (ISSP) on 11 August 2013.

Worked examples

Example 1 — a first encounter with IC 1296

Start with the simplest possible case. Write down what IC 1296 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 IC 1296 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 IC 1296 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 IC 1296

In research: IC 1296 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 IC 1296 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: IC 1296 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Barred spiral galaxies, Discoveries by Edward Emerson Barnard, IC objects, so understanding it makes those chapters shorter.
In everyday life: Look for IC 1296 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.

Frequently asked questions

What is IC 1296 in simple terms?

Why does IC 1296 matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IC 1296?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
