NGC 1373

NGC 1373 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 1373 rather than just read about it. In short: NGC 1373 is a dwarf elliptical galaxy located 61 million light years away in constellation of Fornax. The galaxy was discovered by astronomer John Herschel on November 29, 1837, and is a member of the Fornax Cluster.

Key takeaways

NGC 1373 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 1373 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 1373 from memory before moving on to harder problems.

Reference excerpt

NGC 1373 is a dwarf elliptical galaxy located 61 million light years away in constellation of Fornax. The galaxy was discovered by astronomer John Herschel on November 29, 1837, and is a member of the Fornax Cluster. NGC 1373 is a host to a supermassive black hole with an estimated mass of 4.6 million solar masses. 63 known globular clusters have been observed surrounding NGC 1373, along with 13 observed planetary nebulae.

Physical characteristics NGC 1373 is one of the most compact and faint elliptical galaxies in the Fornax Cluster. As NGC 1373 is a compact elliptical galaxy, in the Fornax Cluster, it is expected to have older and more metal-rich populations of stars than similar compact elliptical galaxies of lower masses. It is thought that NGC 1373 originated as a more extended galaxy that transformed into a compact dwarf as it fell falling through the cluster. NGC 1373 appears to be interacting with the galaxy NGC 1374 and is separated from the galaxy by a distance of around 980,000 ly (0.3 Mpc). This is evident as observations using the VLT Survey Telescope reveal the presence of a faint filament of matter connecting the two galaxies.

Worked examples

Example 1 — a first encounter with NGC 1373

Start with the simplest possible case. Write down what NGC 1373 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 1373 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 1373 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 1373

In research: NGC 1373 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 1373 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 1373 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1837, Dwarf elliptical galaxies, Fornax, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 1373 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.
