NGC 1106

NGC 1106 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 1106 rather than just read about it. In short: NGC 1106 is a lenticular, non-barred spiral galaxy with considerable structure (type SA0^+), located in the Perseus constellation. It was discovered by astronomer John Herschel on 18 September 1828.

Key takeaways

NGC 1106 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 1106 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1106 from memory before moving on to harder problems.

Reference excerpt

NGC 1106 is a lenticular, non-barred spiral galaxy with considerable structure (type SA0^+), located in the Perseus constellation. It was discovered by astronomer John Herschel on 18 September 1828.

Characteristics In 2016, astronomers confirmed NGC 1106 contains a Compton-thick active galactic nucleus, after extensive analysis of the galaxy's X-ray spectra. Due to the AGN in its center, it's also classified as a type II Seyfert galaxy, meaning it has the characteristic bright core of a Seyfert galaxy, as well as appearing bright when viewed at infrared wavelengths.

Star formation A study released in 2022 detected active star formation in NGC 1106. The research involved the use of far-ultraviolet and mid-infrared analysis, both techniques are extensively used as star formation rate tracers.

NGC 1086 Group NGC 1106 is a member of the NGC 1086 Group (also known as LGG 78). The other three galaxies are: NGC 1086, UGC 2349, and UGC 2350.

Worked examples

Example 1 — a first encounter with NGC 1106

Start with the simplest possible case. Write down what NGC 1106 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 1106 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 1106 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 1106

In research: NGC 1106 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 1106 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 1106 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1828, Discoveries by John Herschel, Galaxies discovered in 1828, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1106 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.
