NGC 1589

NGC 1589 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 1589 rather than just read about it. In short: NGC 1589 is a large spiral galaxy in the constellation of Taurus. Its velocity with respect to the cosmic microwave background is 3,729±9 km/s, which corresponds to a Hubble distance of 179.4 ± 12.6 Mly (55.00 ± 3.85 Mpc).

Key takeaways

NGC 1589 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 1589 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1589 from memory before moving on to harder problems.

Reference excerpt

NGC 1589 is a large spiral galaxy in the constellation of Taurus. Its velocity with respect to the cosmic microwave background is 3,729±9 km/s, which corresponds to a Hubble distance of 179.4 ± 12.6 Mly (55.00 ± 3.85 Mpc). However, three non-redshift measurements give a closer mean distance of 154.38 ± 1.90 Mly (47.333 ± 0.584 Mpc). It was discovered by German-British astronomer William Herschel on 19 December 1783.

NGC 1589 group NGC 1589 is the largest galaxy in a group of galaxies named after it. The NGC 1589 group (also known as LGG 117) has nine galaxies, including NGC 1586, NGC 1587, NGC 1588, NGC 1620, UGC 3054, UGC 3058, UGC 3072 and UGC 3080.

Supernova One supernova has been observed in NGC 1589: SN 2001eb (Type Ia, mag. 16.3) was discovered by Tom Boles on 29 August 2001.

Worked examples

Example 1 — a first encounter with NGC 1589

Start with the simplest possible case. Write down what NGC 1589 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 1589 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 1589 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 1589

In research: NGC 1589 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 1589 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 1589 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1783, Discoveries by William Herschel, MCG objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1589 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.
