NGC 3319

NGC 3319 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 3319 rather than just read about it. In short: NGC 3319 is a barred spiral galaxy in the constellation Ursa Major. It was discovered by William Herschel on Feb 3, 1788.

Key takeaways

NGC 3319 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 3319 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 3319 from memory before moving on to harder problems.

Reference excerpt

NGC 3319 is a barred spiral galaxy in the constellation Ursa Major. It was discovered by William Herschel on Feb 3, 1788. It is rich in gas and lacks a galactic bulge. NGC 3319 is relatively isolated. It is in a small group of galaxies including NGC 3104, NGC 3184, and NGC 3198. The nearest galaxy to it is probably NGC 3198, 4.2 million light-years (1.3 megaparsecs) away. NGC 3319 is a Seyfert galaxy, with an active galactic nucleus (AGN) that was identified in 2018. NGC 3319 is a candidate for hosting an intermediate-mass black hole. The probability of having the black hole having a mass less than 105 M☉ has been placed at 84%.

Worked examples

Example 1 — a first encounter with NGC 3319

Start with the simplest possible case. Write down what NGC 3319 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 3319 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 3319 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 3319

In research: NGC 3319 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 3319 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 3319 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1788, Barred spiral galaxies, Barred spiral galaxy stubs, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 3319 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.
