NGC 1343

NGC 1343 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 1343 rather than just read about it. In short: NGC 1343 is a peculiar barred spiral galaxy located in the constellation Cassiopeia, with its eastern edge extending slightly into Camelopardalis. The galaxy is notable for its intense starburst activity within its bright blue inner ring, which surrounds a compact core.

Key takeaways

NGC 1343 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 1343 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1343 from memory before moving on to harder problems.

Reference excerpt

NGC 1343 is a peculiar barred spiral galaxy located in the constellation Cassiopeia, with its eastern edge extending slightly into Camelopardalis. The galaxy is notable for its intense starburst activity within its bright blue inner ring, which surrounds a compact core. A faint bar connects to this ring, and subtle spiral arms with visible star clusters extend outward. NGC 1343 is also associated with a faint dwarf companion galaxy and has hosted a recorded supernova event. It was discovered by the German-British astronomer William Herschel on October 17, 1786. Due to its low surface brightness and position behind the Milky Way’s dust, NGC 1343 is relatively faint when observed from Earth.

Structure and companion galaxy The nearly circular inner ring is a distinctive feature, likely formed by resonance effects typical in barred galaxies. It shows a slight gap and is connected to the core by a faint bar. A faint dwarf companion, designated HFLLZOA G134.74+13.65, is located northeast of the core. A possible faint star stream or bridge suggests gravitational interaction, though NGC 1343's disk shows minimal distortion.

Supernova One supernova has been observed in NGC 1343. SN 2008dv (Type Ic, mag. 18.2) was discovered by Japanese astronomer Kōichi Itagaki on 1 July 2008.

Worked examples

Example 1 — a first encounter with NGC 1343

Start with the simplest possible case. Write down what NGC 1343 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 1343 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 1343 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 1343

In research: NGC 1343 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 1343 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 1343 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Barred spiral galaxies, Cassiopeia (constellation), Discoveries by William Herschel, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1343 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.
