NGC 5713

NGC 5713 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 5713 rather than just read about it. In short: NGC 5713 is a peculiar, asymmetric galaxy in the constellation Virgo, about 90 million light-years away. Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 is very different from most normal spiral galaxies.

Key takeaways

NGC 5713 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 5713 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 5713 from memory before moving on to harder problems.

Reference excerpt

NGC 5713 is a peculiar, asymmetric galaxy in the constellation Virgo, about 90 million light-years away. Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 is very different from most normal spiral galaxies. While most spiral galaxies either have either two well-defined spiral arms or a filamentary spiral-like structure, this spiral galaxy has only one visible spiral arm in its disk. This makes it a galaxy of the Magellanic type. Gravitational interactions with the nearby spiral galaxy NGC 5719 may be responsible for producing the disturbed, asymmetric structure including the single spiral arm. NGC 5713 is at the center of a small group of spiral galaxies that also includes NGC 5691, NGC 5705, and NGC 5719. The satellite galaxies around both NGC 5713 and NGC 5719 have somewhat different velocities, and as the two galaxies interact it appears that their respective satellite systems are merging. It is a member of the NGC 5746 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.

Star formation

Compared to many other nearby spiral galaxies, NGC 5713 appears to be a site of relatively intense star formation activity. The boost in star formation in NGC 5713 may be linked to the gravitational interactions with NGC 5719. The interactions are expected to disturb the orbits of gas clouds in NGC 5713, thus causing the clouds to collide with each other. The collisions cause the clouds to collapse and form new stars, hence leading to the increased star formation seen in NGC 5713.

Worked examples

Example 1 — a first encounter with NGC 5713

Start with the simplest possible case. Write down what NGC 5713 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 5713 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 5713 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 5713

In research: NGC 5713 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 5713 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 5713 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Interacting galaxies, NGC objects, Peculiar galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 5713 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.
