NGC 3464

NGC 3464 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 NGC 3464 rather than just read about it. In short: NGC 3464 is a barred spiral galaxy in the constellation of Hydra, discovered 14 January 1886 by Ormond Stone. Supernovae Four supernovae have been observed in NGC 3464: SN 2002J (Type Ic, mag. 16.8) was discovered by LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches) on 21 January 2002.

Key takeaways

NGC 3464 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NGC 3464 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 3464 from memory before moving on to harder problems.

Reference excerpt

NGC 3464 is a barred spiral galaxy in the constellation of Hydra, discovered 14 January 1886 by Ormond Stone.

Worked examples

Example 1 — a first encounter with NGC 3464

Start with the simplest possible case. Write down what NGC 3464 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 NGC 3464 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 NGC 3464 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 NGC 3464

In research: NGC 3464 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 NGC 3464 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: NGC 3464 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Barred spiral galaxies, Barred spiral galaxy stubs, Discoveries by Ormond Stone, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 3464 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.
