NGC 6045

NGC 6045 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 6045 rather than just read about it. In short: NGC 6045 is a barred spiral galaxy located about 450 million light-years away in the constellation Hercules. NGC 6045 was discovered by astronomer Lewis Swift on June 27, 1886 and is a member of the Hercules Cluster.

Key takeaways

NGC 6045 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 6045 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 6045 from memory before moving on to harder problems.

Reference excerpt

NGC 6045 is a barred spiral galaxy located about 450 million light-years away in the constellation Hercules. NGC 6045 was discovered by astronomer Lewis Swift on June 27, 1886 and is a member of the Hercules Cluster. It is also a LINER galaxy.

Possible interaction NGC 6045 is very luminous in both X-ray and infrared light. This high luminosity in both X-ray and infrared has been suggested to be the result of a starburst event in the galaxy. It is thought that starburst events are caused by interactions or mergers with other galaxies. Also, NGC 6045 has a warped disk which may be due to an interaction with the elliptical galaxy NGC 6047 which lies around ~320,000 ly (97 kpc) from the galaxy.

Worked examples

Example 1 — a first encounter with NGC 6045

Start with the simplest possible case. Write down what NGC 6045 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 6045 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 6045 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 6045

In research: NGC 6045 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 6045 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 6045 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arp objects, Astronomical objects discovered in 1886, Barred spiral galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 6045 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.
