NGC 6008

NGC 6008 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 6008 rather than just read about it. In short: NGC 6008 (sometimes referred to as NGC 6008A) is a barred spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 4,959 ± 8 km/s, which corresponds to a Hubble distance of 73.2 ± 5.1 Mpc (~239 million light-years).

Key takeaways

NGC 6008 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 6008 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 6008 from memory before moving on to harder problems.

Reference excerpt

NGC 6008 (sometimes referred to as NGC 6008A) is a barred spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 4,959 ± 8 km/s, which corresponds to a Hubble distance of 73.2 ± 5.1 Mpc (~239 million light-years). It was discovered by French astronomer Édouard Stephan on 10 June 1880. NGC 6008 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.

NGC 6052 Group According to A.M. Garcia, NGC 6008 is part of the NGC 6052 group (also known as LGG 403). This group has at least 13 members: NGC 5975, NGC 6020, NGC 6030, NGC 6032, NGC 6052, NGC 6060, NGC 6073, IC 1132, CGCG 137-037, UGC 10127, UGC 10197, and UGC 10211.

Supernova One supernova has been observed in NGC 6008:

SN 2023apm (Type II-P, mag. 19.45) was discovered by the Zwicky Transient Facility on 23 January 2023.

Worked examples

Example 1 — a first encounter with NGC 6008

Start with the simplest possible case. Write down what NGC 6008 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 6008 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 6008 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 6008

In research: NGC 6008 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 6008 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 6008 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1880, Barred spiral galaxies, Discoveries by Édouard Stephan, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 6008 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.
