NGC 5308

NGC 5308 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 5308 rather than just read about it. In short: NGC 5308 is an edge-on lenticular galaxy in the constellation of Ursa Major. It was discovered on 19 March 1790 by William Herschel.

Key takeaways

NGC 5308 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 5308 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 5308 from memory before moving on to harder problems.

Reference excerpt

NGC 5308 is an edge-on lenticular galaxy in the constellation of Ursa Major. It was discovered on 19 March 1790 by William Herschel. It was described by John Louis Emil Dreyer as "bright, pretty large" when he compiled the New General Catalogue. A small, irregular galaxy near NGC 5308 has been given the designation LEDA 2802348. NGC 5308 was imaged by the Hubble Space Telescope in 2016. The galaxy appears to be a flat, smooth disk, typical of most lenticular galaxies. Many large globular clusters orbit the galaxy; these are visible as tiny dots surrounding the galaxy, and are mostly made of old, aging stars similar to the galaxy itself.

NGC 5322 Group According to A.M. Garcia, the galaxy NGC 5308 is a member of the NGC 5322 group (also known as LGG 360), which contains at least ten other galaxies, including NGC 5322, NGC 5342, NGC 5372, NGC 5376, NGC 5379, NGC 5389, UGC 8684, UGC 8714, and UGC 8716.

Supernova One supernova has been observed in NGC 5308: SN 1996bk (Type Ia, mag. 14.5) was discovered by Piero Mazza and Stefano Pesci on 12 October 1996, located 10.5" south and 17.9" west of center of the galaxy.

Worked examples

Example 1 — a first encounter with NGC 5308

Start with the simplest possible case. Write down what NGC 5308 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 5308 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 5308 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 5308

In research: NGC 5308 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 5308 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 5308 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lenticular galaxies, Lenticular galaxy stubs, NGC objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 5308 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.
