NGC 1349

NGC 1349 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 1349 rather than just read about it. In short: NGC 1349 is a lenticular galaxy in the constellation Taurus. The galaxy lies about 290 million light years away from Earth, which means, given its apparent dimensions, that NGC 1349 is approximately 80,000 light years across.

Key takeaways

NGC 1349 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 1349 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1349 from memory before moving on to harder problems.

Reference excerpt

NGC 1349 is a lenticular galaxy in the constellation Taurus. The galaxy lies about 290 million light years away from Earth, which means, given its apparent dimensions, that NGC 1349 is approximately 80,000 light years across. It was discovered by Lewis Swift on December 20, 1886. The galaxy is characterised as a lenticular galaxy, having a disk and a bulge. Almost 95% of the stars in the bulge are old, created more than 6 billion years ago, while the stars in the disk are younger, as 59% have ages between 1 and 6 billion years. The spectrum of the nuclear region shows it is a combination of a LINER and a star formation area. The outer region of the galaxy features structures that look like spiral arms. These spiral structures host about 80% of the galaxy's total H-alpha emission and are a place of active star formation, in HII regions. The star formation rate is estimated to be 0.1–0.3 M☉ per year. The galaxy appears to be isolated.

Worked examples

Example 1 — a first encounter with NGC 1349

Start with the simplest possible case. Write down what NGC 1349 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 1349 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 1349 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 1349

In research: NGC 1349 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 1349 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 1349 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1886, Discoveries by Lewis Swift, LINER galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1349 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.
