NGC 7329

NGC 7329 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 7329 rather than just read about it. In short: NGC 7329 is a large barred spiral galaxy located in the constellation Tucana. Its velocity with respect to the cosmic microwave background is 3,148±8 km/s, which corresponds to a Hubble distance of 151.4 ± 10.6 Mly (46.43 ± 3.25 Mpc).

Key takeaways

NGC 7329 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 7329 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 7329 from memory before moving on to harder problems.

Reference excerpt

NGC 7329 is a large barred spiral galaxy located in the constellation Tucana. Its velocity with respect to the cosmic microwave background is 3,148±8 km/s, which corresponds to a Hubble distance of 151.4 ± 10.6 Mly (46.43 ± 3.25 Mpc). Additionally, 29 non-redshift measurements give a closer mean distance of 145.67 ± 3.35 Mly (44.662 ± 1.028 Mpc). It was discovered by British astronomer John Herschel on 20 July 1835. The luminosity class of NGC 7329 is II and it has a broad HI line.

Supernovae Two supernovae have been observed in NGC 7329:

SN 2006bh (Type Ia, mag. 14.8) was discovered by South African amateur astronomer Berto Monard, in Pretoria, on 2 April 2006. SN 2009iu (Type Ib, mag. 15.5) was discovered on 1 September 2009 by the CHASE (Chilean Automatic Supernova Search) project, a project searching for supernovae visible from astronomical observatories in the southern hemisphere.

NGC 7329 group NGC 7329 is a member of a group of galaxies that bears its name. The NGC 7329 group (also known as LGG 462) has at least 11 members, including NGC 7358, NGC 7408, NGC 7417, IC 5222, IC 5227, IC 5244, IC 5250, IC 5266, IC 5272 and ESO 109-32.

Worked examples

Example 1 — a first encounter with NGC 7329

Start with the simplest possible case. Write down what NGC 7329 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 7329 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 7329 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 7329

In research: NGC 7329 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 7329 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 7329 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1835, Barred spiral galaxies, Discoveries by John Herschel, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 7329 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.
