NGC 5483

NGC 5483 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 5483 rather than just read about it. In short: NGC 5483 is a barred spiral galaxy in the constellation Centaurus. The galaxy lies about 60 million light years away from Earth, which means, given its apparent dimensions, that NGC 5483 is approximately 60,000 light years across.

Key takeaways

NGC 5483 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 5483 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 5483 from memory before moving on to harder problems.

Reference excerpt

NGC 5483 is a barred spiral galaxy in the constellation Centaurus. The galaxy lies about 60 million light years away from Earth, which means, given its apparent dimensions, that NGC 5483 is approximately 60,000 light years across. It was discovered by John Herschel on March 15, 1836. NGC 5483 has a small bulge and a small bar. From the ends of the bar emerge two well defined spiral arms in a grand design pattern. The arms have initially some knots but their outer parts are smoother. They fade after completing about half a revolution, when they became wide and diffuse. The galaxy has a faint outer arm to the north. There are also visible spiral arcs, which do not appear to be branched of the principal arms, and dust lanes. The galaxy has a large complex HII region that is about 4 arcseconds across. The star formation rate of the galaxy is estimated to be about 3.1 M☉ per year. In the centre of the galaxy lies a supermassive black hole, whose mass is estimated to be 106.79 ± 0.38 (2.6 - 15 millions) M☉, based on the pitch angle of the spiral arms. One supernova has been detected in NGC 5483, PSNJ14102342-4318437. It was discovered on 15 December 2015 by MASTER at an apparent magnitude of 14.4. It was classified spectrographically as a type Ib supernova. NGC 5483 doesn't belong to a galaxy group, but it is located in a galaxy cloud which also includes the galaxies IC 4362, IC 4386, IC 4402, and IC 4441.

Worked examples

Example 1 — a first encounter with NGC 5483

Start with the simplest possible case. Write down what NGC 5483 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 5483 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 5483 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 5483

In research: NGC 5483 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 5483 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 5483 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1836, Barred spiral galaxies, Centaurus, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 5483 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.
