NGC 1692

NGC 1692 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 1692 rather than just read about it. In short: NGC 1692 is a lenticular galaxy and also a LINER galaxy located in the constellation of Eridanus. The galaxy has a redshift of (z) 0.035 which corresponds to a Hubble distance of 156 ± 11 megaparsecs or 510 million light-years and it was first discovered by an American astronomer named Ormond Stone on 11 December, 1885.

Key takeaways

NGC 1692 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 1692 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1692 from memory before moving on to harder problems.

Reference excerpt

NGC 1692 is a lenticular galaxy and also a LINER galaxy located in the constellation of Eridanus. The galaxy has a redshift of (z) 0.035 which corresponds to a Hubble distance of 156 ± 11 megaparsecs or 510 million light-years and it was first discovered by an American astronomer named Ormond Stone on 11 December, 1885.

Description NGC 1692 appears to look like an elliptical galaxy despite being categorized as a lenticular according to NASA/IPAC Database website, with an undisturbed appearance. It has one companion, an edge-on spiral galaxy located south-east from it with a C-shaped appearance. Evidence also shows that NGC 1692 also presence of excessive ultraviolet emission, traces of young stellar populations but absence of emission lines in its optical spectrum. The galaxy has also been categorized as a radio galaxy of low-luminosity or alternatively, a weak-line radio galaxy (WLRG) of Fanaroff-Riley Type I classification. When imaged with Very Large Array (VLA), it has a double lobed structure with a radio jet located towards the direction of north-west, which terminates in a hotspot region. However when the southern part was observed, there is no radio jet but instead a warm-spot feature located at the edge of the radio lobe. Earlier imaging made in 1993, found evidence it is surrounded by diffused radio emission but no sign of any radio core. There is also a presence of a steep power-law component. Other imaging also showed the source is compact with a double structure with radio emission likely originating from hotspots rather the core region. A study of its host galaxy has found out, there are evidence of flux on the western side, just beyond its nucleus region. This suggests the galaxy might have an asymmetric appearance.

Worked examples

Example 1 — a first encounter with NGC 1692

Start with the simplest possible case. Write down what NGC 1692 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 1692 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 1692 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 1692

In research: NGC 1692 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 1692 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 1692 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1885, Discoveries by Ormond Stone, ESO objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1692 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.
